We believe in exposing audiences to diverse theatrical works which instill a sense of wonder, arouse empathy, and celebrate playing and the spirit of play.
We believe theatre available to young people should fortify community and family relationships across age groups through the shared experience of performed stories.
We believe in works of diversity in style, tradition, ethnicity, ability, gender, and age.
We work to distill the concept of 'all ages' experience with critical, discerning artistry.
We stand for community engagement, artistic enrichment and professional development.
We want Solar Stage to be a part of the village that raises a child.
Solar Stage is a registered charitable organization, with professionally audited statements annually and receives funding and support from the Ontario Arts Council Endowment Fund.

Stage Manager: Julie Rush; Set and Costume Designer: Rebecca Ballarin; Lighting Designer: Yehuda Fisher

In spite of the discovery of small cracks in the shield building at the Davis-Besse Nuclear Power Station, FirstEnergy expects to have the plant return to service around the end of November.
Ronald Seeholzer, Vice President Investor Relations, says in a letter to investors dated Oct. 31 that a team of structural concrete experts and Davis-Besse engineers have determined the cracking doesn't affect the facility's structural integrity or safety.
It was Sunday evening after Thanksgiving break in 2009 the Escobar sisters, Abby and Gabby (born just 15 months apart) were at their East Toledo home relaxing before school started again when their mother discovered that an electric blanket had caught fire upstairs in her bedroom.
The flames moved quickly across the carpet and soon their entire home was engulfed in flames. Emotions were running high as they called the fire department. As they watched their house burning, tears flowed knowing that they were losing so much. In the end, no one was hurt or injured, but the Escobars lost everything and did not have insurance to cover the damages.
Negotiations for the Ottawa County Sheriff's Department union have entered the fact-finding stage.
"It (the contract proposal) went to the fact finder last Friday," said Sheriff Steve Levorchick. "They should come back in 30 days with a ruling. It will either be settled or head to conciliation."
Last May, veteran police sergeant Michael Powell gave a presentation to Woodmore's High School students.
This year, Sgt. Powell came back to Woodmore to spread the message of being street smart to seventh grade students. Powell shared the presentation with parents and community members as well.
In its Oct. 17 and Oct. 24 editions, The Press published its Voters' Guide for the November 8 General Election that included candidate profiles in Northwood and Oregon. In the Oct. 24 edition of The Press, Oregon city council and school board candidates answered a series of questions posed by The Press regarding issues facing the community. The Voters' Guide published seven of eight Oregon city council candidates' answers to the questions. The answers of Mike Sheehy, an incumbent councilman who is also president of council, were accidentally omitted. The Press regrets the error. Here are Sheehy's answers to the questions:

Sitting under an umbrella at a little pizza joint in the Paseo Arts District it's hard to imagine I'm in Oklahoma City.
With a locally brewed F5 Ale in hand, the ultra-hoppy beer feels more Pacific Northwest than American Heartland. But the scorching heat and hints of Southwest architecture places me in Oklahoma.
A new piece of public art is going up on the southwest corner of the Memphis Light, Gas and Water Division parking garage Downtown. The UrbanArt Commission and city of Memphis called for entries that would display the city's rich African-American and cultural heritage. The winning design is by Michael Roy and Derrick Dent. The 70-foot-tall mural at South Main and Dr. Martin Luther King Jr. Avenue should be completed in the next couple of weeks.
2014: Hard Rock Cafe Memphis' new location opens at the corner of Beale and Second streets after 17 years at Beale and Hernando.
1976: ZZ Top headlines a Fourth of July concert at Liberty Bowl Memorial Stadium that also includes Lynyrd Skynyrd, Blue Oyster Cult and the Outlaws. Tickets are $12 at the gate.
Aretha Franklin's birthplace at 406 Lucy Ave. in South Memphis is getting an encore. Environmental Court Judge Larry Potter has suspended his demolition order for six weeks to give some breathing room to the LeMoyne-Owen College Community Development Corp.'s recently revived campaign to turn the house into a museum.
More than 150 years ago, we fought our nation's most bloody war, a conflagration that claimed 620,000 lives, almost as many as were killed in all other American war efforts combined.
Despite the horror of it all, we just can't seem to learn a lesson, possibly because of Southern hardheadedness, and a century and a half later, we seem doomed to an eternal task: pushing Sisyphus' rock to the top of a hill only to have it chase us back to the bottom.
A local business owner has stepped up with $15,000 to save Aretha Franklin's birth home, but the effort may be too little too late.
The dilapidated house at 406 Lucy Ave. is headed for demolition unless a realistic and fully-funded plan emerges within the week, said Steve Barlow, an attorney with blight-fighting law firm Brewer & Barlow PLC.
Loflin Yard will be packed Monday night with creatives and young professionals who for almost three years now have been gathering monthly for meetings at different hotspots around the city that follow the same format.
He found the old South Memphis movie theater that became Stax Records. He recorded more than 100 hit records for numerous record labels in a 10-year period in a nondescript building at Danny Thomas Boulevard and Chelsea Avenue.
Six groups from Memphis and elsewhere inspected the Mid-South Coliseum this week, taking the city of Memphis up on an offer of four hours each to look over the mothballed 12,000-seat arena.
The city made the offer after it allowed a tour of the arena by the Coliseum Coalition and architects as the group pursues a plan to possibly restore or renovate the coliseum for future use.
You didn't think this would be easy, did you?
If it was, any one of our previous efforts at overcoming a heritage and history of violence as a way of life would have done the trick by now.
The Memphis City Council's budget committee completed its budget reviews Tuesday, May 31, recommending a 1.5 percent pay raise for city employees other than fire and police and $300,000 in grant funding to hire a full-time director for the Whitehaven Economic Development Council.
It took six hours. But the Memphis City Council's budget committee completed its budget reviews Tuesday, May 31, with a recommendation of a 1.5 percent pay raise for city employees other than fire and police and $300,000 in grant funding to hire a full-time director for the Whitehaven Economic Development Council.
The innovation efforts starting to bear fruit in Memphis' medical community didn't just appear miraculously.
Leaders of this effort started to plow rock-hard ground years ago.
While business innovation is difficult, health and medical innovation aimed at commercial applications is much more brutal. The reward for a breakthrough at this level is greater, but so is the risk, with investors' capital burned through quickly whether or not an idea is brought to fruition.
Memphis City Council Budget Committee Chairman Edmund Ford Jr. likens it to the television show "Shark Tank."
Instead of entrepreneurs, leaders of nonprofits made their pitches to the budget committee Tuesday, May 24, for grants from the council as part of the budget process.
That didn't take long. Fired one day, hired the next for Dave Joerger now formerly of the Grizz.
In the 1970s Memphians could watch back-to-back broadcasts of professional wrestling and roller derby taking place at the Mid-South Coliseum.
The popularity of both full-contact sports eventually tapered off. While World Wrestling Entertainment has since developed a national audience, the latter has reemerged as a women-only sport with a grassroots following of computer geeks and soccer moms, said Brooke Gettys, co-captain with Memphis Roller Derby.
South Street is now named G.E Patterson Boulevard in one of two name changes since the thoroughfare was a dirt road trod by horses and the wagons they pulled.
The only reminder of the street's status as an epicenter of the violence 150 years ago this month that killed 46 people and burned every black church and school in the city to the ground is a plaque unveiled Sunday, May 1, in Army Park.
I thought about skipping church Sunday and playing golf. After listening to the House of Representatives' debate on the Bible bill, I could probably skip church for a month and still be in good standing.

Main St. in Collierville. The students' research centered on the ways Collierville contributed to the World War II effort and was affected by the war. Visit colliervillemuseum.org.
A week ago, the board of the Overton Park Conservancy had a visitor at its meeting – Richard Smith, the Memphis Zoo's representative in the ongoing private mediation talks between the conservancy and the zoo.
As much as Tennessee Republicans want to put a happy face on the departure of Senate Speaker and Lt. Gov. Ron Ramsey, holding it together in the wake of his departure will be an awesome task.
The local effort to fight blight has been in recent years a machete-like action to cut through bureaucratic red tape and get possession of the most blighted properties.
So there have been a lot of press conferences where bulldozers are featured prominently to demolish the targeted property.
J.R. "Pitt" Hyde III is not Memphis' most famous name across the state of Tennessee. But he is an important name, has a deep and rich story worth telling, and that is exactly the point.
Let the coaching drumbeat resume after the Tigers Sunday post-season collapse one game past Tulsa.A confession here – I am so sports challenged that I thought UConn was a team from Alaska until I saw it spelled out.In my defense, who associates Huskies with Connecticut?My point is what happens next isn't just about basketball. It's about a change with a good track record of being emotional in the worst way.It's linked to how we want to be known for treating people and what they think of us as a result of that.In those two areas, it's never just business. It's always personal.Josh Pastner's four predecessors were each very different case studies in this regard.It could have been any stop in any city with a basketball court and a one-and-done star he could find and recruit to John Calipari. But he still had to hide under a blanket in the back seat of a car on the way to the airport and lie about it long after everyone knew.Knew about the Kentucky job that is. The mess he left at the university would surface shortly thereafter.Tic Price was two fast seasons and the proof that the Memphis job isn't just about what happens on the court and the attendance at games.Price was clearly excited about coming to Memphis. He clearly understood the importance and heritage of Tigers basketball and valued it. And he wasted no time at all getting lost in the Memphis that is not a part of that all encompassing world.It was the only job Larry Finch wanted and ultimately the job he couldn't continue to have. That after ignoring conventional wisdom as a player and coming from Melrose High to Memphis State, bringing a beloved team with him and then picking Memphis again in the ABA over the Lakers in the NBA.None of that was considered in pushing him out the door and then naming a building after him.Dana Kirk wanted to be the hustler John Calipari was. He was certainly impersonal enough about it and he took the team to an era where a post-season NCAA bid was expected and is still expected to this day.But his impersonality exacted a high cost and he paid most of that cost. Although you could argue the experience for his team that produced some legendary players also made some of them legendary casualties of his emotional distance. It didn't allow him to go elsewhere because he never figured out that he was being underestimated just as much as the team whose needs he ignored was in the national view of college basketball. While Calipari dodged big trouble twice, Kirk wasn't even in Calipari's league when it came to ducking and timing.We are past our inferiority complex. That's what the last NFL drive of the 1990s did for us. But it's not necessarily a bad thing that we see the people chosen to occupy these very public positions as a reflection to the world of who we are.
How was your weekend, Memphis? Here's our weekly roundup of local happenings you need to know about, from the first look at the Greater Memphis Chamber's proposed diversity program to a truly Irish celebration of St. Paddy's Day.
Anne Dixon has joined BRIDGES as vice president of finance and chief financial officer. Dixon, who is a Bridge Builders alumna, is responsible in her new role for financial reporting and analysis to help BRIDGES leadership in performing their responsibilities.
How was your weekend, Memphis? In a few short days it'll be time to "spring forward" – but let's not get ahead of ourselves. First, check out our weekly roundup of area happenings, from a discussion with local changemakers to the inaugural Memphis Black Restaurant Week…
The Midtown Memphis Development Corp. is set to honor seven individuals and organizations for their "mojo" in promoting and preserving the Midtown area.
To each his or her own on Valentine's Day observances Sunday that become Valentine's Day memories with the arrival of Monday.
The Majestic Grille, for instance, had the movies Roman Holiday and Casablanca back to back on the screen of the movie theater turned restaurant.No sound, but you really don't need sound for the scene where Audrey Hepburn takes the throne with Gregory Peck and a beatnik Eddie Albert among the press corps at the rope line.And The Majestic saved The Second Line in Overton Square with a loaner of some champagne after Second Line ran a bit short.Chef Kelly English thanked the Majestic via Twitter for "saving our sweet Valentine's Day asses."
The Memphis Symphony Orchestra has been awarded a grant from The Andrew W. Mellon Foundation for planning a musician diversity fellowship program.
The foundation, which invests in the arts and cultural heritage, has been a strong supporter of MSO innovation and community engagement work in the past.
After the January into February weekend we had with its outbreak of spring fever, you might wonder if groundhogs are allowed to change their minds or if shadows that are the result of television lights count as a prediction on the winter's length.Or maybe it would be appropriate to have a weather map that includes the Groundhog Day immunity zones – areas where the long shadow of the groundhog does not venture.Note to television meteorologists: This would in no way interfere with your right to declare large parts of your viewing areas as places of "potentially severe weather" far into the future. But you will need a different color for the Groundhog Immunity Zones.
In sports, it is natural for some – maybe even many – to say what a player, coach, team or even a city can't do. Memphis knows this well.
There were doubts about the viability of a Downtown minor-league baseball park. But 16 years after AutoZone Park opened at Third Street and Union Avenue, the ballpark is as beautiful as ever – thanks in part to some $6.5 million in upgrades following the team's purchase by the parent St. Louis Cardinals.
You will find Memphis sports fans everywhere – including in the Redbirds dugout at AutoZone Park.
"Our players like having the NBA here and FedExForum nearby," said Memphis Redbirds general manager Craig Unger.
Everybody talks about the weather but nobody does anything about it – isn't that how the saying goes?In our case, it might be better to say everybody talks about the television weather coverage but nobody does anything about it.As we all know now, Memphis dodged the "blizzard" warning artfully and passive-aggressively teased by several television stations who shall go un-named here because they know who they are and you do too.That's because they spent much of the day of "the blizzard that wasn't" whining about the reaction from viewers who complained about the hype and then the promos the stations ran the day of the big fizzle.We didn't get much in the way of snow in Memphis, but we got a couple of feet of hype.
We hope everyone survived Snow Terror '16 and is looking forward to a fun, productive week ahead that's free of milk and bread runs. (Saturday's high temp is 60 degrees – woohoo!) Here's your weekly rundown of events and happenings worth paying attention to…
Way back in the 1990s, perhaps before the Grizzlies and FedExForum were even a twinkle in anyone's eye, Chris Wallace came to Memphis and The Pyramid for a preseason NBA game featuring Michael Jordan and the Chicago Bulls.
Democratic presidential contender and Vermont Senator Bernie Sanders didn't make it the city after all following the weekend's debate among the Democratic presidential contenders.
This week, hundreds of investors, community builders and federal leaders gathered at the third annual Rural Opportunity Investment Conference, which ended with a discussion of spurring economic development through tourism.
On a clear day, the song goes, you can see forever.In Memphis though, it seems that no two politicians will see exactly the same thing or have precisely the same opinion.On a somewhat sunny but not necessarily clear Tuesday in our fair city there was a lot to see.
Football fans in Charlotte, N.C., have had a fun season watching the NFL's Carolina Panthers reel in 15 wins, a near perfect season, and secure the top playoff seed in their conference.
And it could turn out to be quite the edge for the Panthers in their quest to reach the Super Bowl.
Memphis-Mayor elect Jim Strickland announced on Christmas Eve that he will eliminate eight positions in the current administration, one of them vacant. And a ninth positon will become a part-time position. Strickland will also follow through on his long-held desire to end the city's involvement in and funding of the Memphis-Shelby County Music Commission.
University of Memphis football fans will head to Birmingham, Ala., next week to celebrate a bowl game appearance that could see the team finish with 10 wins for a second straight season.
It's been a historical run, and the Birmingham Bowl appearance will give the Tigers a rare chance to play against Auburn University. The game's 11 a.m. kickoff makes it a plausible day trip, but then Birmingham has plenty to offer anyone thinking of spending a night or two.
The Memphis City Council approved the Graceland West planned development Tuesday, Dec. 15, the third phase of Graceland's expansion to a 120-acre campus on both sides of Elvis Presley Boulevard.
The last Memphis City Council meeting of 2015 came with few speeches from departing council members and a crowded agenda as well as a few leftovers the new council will have to deal with.

An applicant seeking to operate a used car lot at 704 Vance Ave. will go before the Shelby County Board of Adjustment Wednesday, Dec. 16, in what seemingly would be a cut-and-dry affair with the BOA staff recommending conditional approval.
For some high school seniors, college is the first time they leave home. For others, college isn't in the cards. A local nonprofit, One Step Initiative, is looking to make college a nearer possibility by sending high school seniors abroad and providing them with ongoing professional support.
Kim Winstead found retirement boring.

Tredwell covers for Swann and Panesar
Follow England's tour of India on ecb.co.uk - click here for all the latest news, exclusive interviews, video highlights and match reports
James Tredwell is to link up with England's squad ahead of the third Test with India at Kolkata next week as cover for fellow spinners Graeme Swann and Monty Panesar.
The Kent off-break bowler was yesterday named in England's Twenty20 and one-day international squads, also against India next month and in January.
The tourists have called him up as an understudy to Swann and Panesar in the middle of a four-match series currently standing at 1-1 following their famous victory at Mumbai.
England seem sure to play two spinners in the final two Tests, after Panesar and Swann combined to take 19 wickets at the Wankhede Stadium - and Tredwell, recently named his county's new captain, is therefore set to fly to India early.
"Tredwell has performed really well for us," said England team director Andy Flower. "He can make a real impact as a spin bowler. He is arriving in Kolkata on December 1 as cover.
"We have some spinners with the Performance Programme. But Tredwell is a senior spinner and will stay with us for the Tests."
The 30-year-old has played just one Test - during March 2010 against Bangladesh in Dhaka where he took six wickets.

ENDODONTIC DENTISTRY provides the background, based on current practice by experts practising in the field of root canal therapy. The endodontic dentist operates on a diseased tooth by opening up access to the canal. Then he debrides the canal which means the removal of all the soft tissue. Then he irrigates the canal to remove any pulpal remnants, any or most of the bacteria, then he enlarges the canal to remove any irregularities or rough surfaces on the inside of the canal, and the enlarging process is continued so that he can now put in a "POINT". A "point" is generally made of a thermoplastic material such as gutta percha, and is indeed referred to as a "GUTTA PERCHA POINT". Silver wire points are also used, but this is not within the purview of this invention. A Gutta Percha point as commonly used is made by "Indian Head Inc" in Switzerland. It consists of a thermoplastic thermoadhesive rod about 11/2 inches long and varying in diameter from 0.010" to 0.090", different diameters being designated by different size numbers.
Many problems arise, which this invention seeks to overcome. One of the problems is repeated X-Rays in the mouth of the patient. X-Raying is always time-consuming and not always accurate, due to the anatomy at the end of the tooth and the angle at which the X-Ray is taken. The time of development and fixing, the X-radiation of progressive and successive X-Rays are all necessary to avoid the over-instrumentation of the canal, which means that the dentist must not force the implant material (the gutta percha point) inside the canal, past the apex of the tooth to create an irritant. But how is the proximity to the apex to be visualized other than by repeated and progressive in-tooth X-Rays? This invention provides an answer as specified in these specifications and in the drawings and claims. The dentist seeks accuracy. The end of the guttapercha "point" theoretically should terminate at the apex of the tooth or one mm. in front of the apex. Many times an X-Ray taken of the apex of the tooth shows the gutta percha point to be shy of the apex when it is actually touching the apex. This is due to the fact that the apex of the tooth is curved towards the film and the Gutta Percha point goes around and also follows the curvature of the root canal and is actually at the very end of the tooth. Many times, and in about 75% of the cases encountered by Dr. Pitz over sixteen years and about 4000 cases of root-canal surgery, the apex is not at the end of the tooth but somewhere off to the side. If the location is not accurate, then, and in the absence of intimate contact of the implanted gutta percha point with the white blood cells, and in the presence of the remnants of the pulpal tissue, or the presence of bacteria, there will be an antigen antibody reaction and anything might happen to traumatise the patient, from an apical scar, to a fulminating abscess, to a cyst. The new implant and the implantation technology invented here, permits the progression of the implant to be read by an electrical resistance reading offered by the conductive carbon fibers contained therewithin or thereabout, and as a final step an electrical force is applied to the same conductive fibers causing them to get heated hot. This heating is regarded as the endogenous heating capability of the new implant. By the application of electrical current, or supersonic vibrations the point will get heated by virtue of the carbon fibers therewithin. The amount of heating, the periods of heating are all controlled by the dentist during the progression of the point towards the apex of the canal. Simultaneously the proximity indicating capability of the point is utilised by an electrical meter reading. This endogenous capability ensures, in the hands of the trained dentist, that the inside of the canal is never overheated to cause tissue damage. The thermoadhesive point is finally tamped ("condensed") into place towards the end of the canal close to the apex. The point in its final place as electrically measured and in addition if desired, endogenously heated, is able to seal the entire root-canal with physiological elegance.
Conventional implantation may be used. Here the dentist heats the point in a flame to soften it. The surface softening is not enough to survive the heat loss suffered by external contact with the substance of the tooth. The point must have enough adhesiveness at its distal end to seal the apical area. A hand tool called the P.C.A. Inserter is used to push in the point. It has a large sphere of metal about 0.025" in diameter above the terminus of the instrument and removed therefrom. This instrument or a similar instrument provides a heat-sink or heat reservoir which is conducted to the terminus of the instrument. There is a failure inherent in this heat-sink type of instrument because of the relative difficulty of conducting heat applied to the proximal end of the implant to the extreme distal end while being heat-sealed to the apical area of the tooth canal.
The novel implantation process, applicable to this proximity indicating gutta percha point, is the implantation during the endogenous heating achieved by the point because of its carbon content or other resistance-heatable materials comprised therein, or thereabouts. Implantation during the endogenous heating utilises an outside electrical current applied to the fibers from proximal end to distal end. It may also utilise ultrasonic energy applied by means known to the ultrasonic art, at the proximal end of the implant during insertion. These instruments in the form of a miniature hammer or a horn are supplied by the Branson Sonic Power Company Danbury Conn. amongst others. The ultrasonic energy applicator may be combined with a drilling means so that there is the maximum effective energy available to be used selectively or in combination, for the root canal preparation and the implantation of the "point", and at some stage, the removal of detritus.
The carbon fibers confer the advantage of transmission through the point from proximal to distal end, with heat-softening achieved either wholly or partly by the ultrasonic action.
When endogenous heating is to be effectuated by the use of an electrical current to achieve electrical resistance heating several modalities are possible. Firstly, a terminal is attached to any part of the point, either along its entire length from proximal to distal and an electric current is furnished to heat the fibers, and by conduction, the circumambient qutta percha. Second, as a second alternative, terminals are attached to a selected portion of the length, and only this portion will undergo resistance heating, with the rest of the point acquiring heat by conduction in the unconnected portions. As a third alternative two points are used as a single point thusly: the distal ends are heat sealed with the fibers of each touching. The proximal ends provide the two terminals for the supply of electric energy. When this occurs, the distal end reaches great heat, probably because of a near short circuit. However, heating can be provided in any manner due to the endogenously heatable quality invented.
The tooth 10 has a pulpal area 14. Pulpal area 14 has been evacuated and detritus removed. Canal containing pulpal area 14 shows one apex 16.
Into the tooth with its prepared root-canal is inserted the invented point 20. Point 20 indicates by electrical or electronic measurement and due to its inherent electrical conductivity as here invented, the position of its distal end with reference to the apex 16. Meter 32 is connected to the proximal end of the point 20. A power source 30 is provided.
This shows the "point". The general number of the figure is 20. Point comprises carboncontaining organic plastic 22.
A thermoplastic resin is coated on to Carbon Fiber Tow. The thermoplastic resin is Gutta Percha. The Tow is Celion� Carbon Fiber K 3000 made by the Celanese Corp New York City N.Y. K 3000 signifies that there are 3000 filaments in the strand of tow. The Gutta Percha is pressure-extruded on the strand of tow using a short barrel 15:1 Rubber Extruder heated 200 F.-225 F.-250 F., the last heat being at the die. Upon cooling the coated Carbon fiber tow is compacted and bonded into a thin rod-shape about 0.013" in diameter. This rod, coated as described, is used as a root-canal implant for narrow root canals.
When inserted into the prepared and evacuated root canal, the distal end when it touches the apex of the tooth will show a conductivity of 40 micro-amps and will indicate to the dentist that optimal intrusion has been reached. At this point heat is applied to either end to soften the entire implant and cause it to thermoadhesively bond to and into the root canal. Meter readings will be different for different sets of conditions.
The tow of example #1 is strip-coated using a strip-coating or "wire coating" die in a four heat-zoned 20:1 barrel. The coating does not completely embed itself around each fiber but is concentrated on the outside surface. The coated tow, when cooled will be a rod-shaped material, about 0.016" in diameter. The ends of the rod make better electrical contact at the apical end of the root canal. The rod is cut into 1.5 inch lengths for root canal implants. Apical indication is at 40 micro-amps approximately. The implant is then heated and caused to flow into and bond into the root canal. Heating may be by conventional means or by use of the endogenous heating capability of the implant as here disclosed, the heating continuing at any stage of implantation.
This was a repeat of Example #1 except that the Gutta Percha was compounded with a filler in particulate form.
______________________________________GUTTA PERCHA: 100 gramsZinc Oxide, Lead-free 50 gramsInert Color 3 gramse.g. Red oxide Color (Fe2 O3)TiO2 0.5 grams______________________________________
Extruder temperatures were increased 5 degrees F. in the first and second zones and by 10 degrees F. in the final zone.
This is an improvement on Example #3, in that the particulate filler is highly radioopaque in comparison with the other ingredients. Here Bismuth oxychloride was used.
______________________________________GUTTA PERCHA: 100 gramsBISMUTH OXYCHLORIDE 25 gramsZinc Oxide, lead free 25 gramsInert color (e.g. Fe2 O3) 3 grams______________________________________
Extruder conditions are the same as Example #3. Virgin Stock is preferred here, because re-cycled or re-worked scrap showed a tendency to develop non-uniform coloration in the finished Gutta Percha Point.
This is an improvement deriving from and pertaining to Examples 1,2,3,4, and succeeding examples where carbon fiber is used. It is the achieving of greater radioopacity of the Carbon Fiber component by plating said fibers with a metal.
______________________________________CARBON FIBER (Tow) Of Example 1 ONE LENGTHMetallized Carbon Fiber Tow ONE LENGTH______________________________________
The lengths are placed alongside each other in any configuration. Thus one length may lie alongside the other and parallel thereto either contiguously or spaced therefrom. The disposition of the lengths may not only be in parallel fashion. They could be twisted together; intertwined; braided, or one length could be served with the other. The measurement of "one length" signifies that the filament content of the two can be widely different whether it be the Graphite fiber tow or the radiopaque metallized Carbon fiber tow, the more Carbon fibers, the more radiolucent, the more metallized carbon fibers the more radioopaque, and their relative proportions may vary from 0.5 to 99.5% and viceversa. In example that was specifically used as a benchmark we used an exact 1:1 ratio, there being 3,000 filaments in the length of Carbon Fiber tow, and 3,000 filaments in the length of the metallized Carbon Fiber Tow, and the same filamentary composition of the same denier was used:
______________________________________For the Graphite Fiber: CELION � 3000 K Carbon Fiber sold by Celanese Corp. New York City N.Y.For the Metallized Carbon Fiber: CORE FIBER was Celion � 3000 K METAL PLATING was Nickel. Silver also was used, and is preferred in this Dental use. CHARACTERISTICS OF METAL PLATING: Coating is 0.5 Microns thick. Coating is 50% of total Fiber weight.______________________________________
While the metallized fibers are more radio-opaque than the Carbon fibers, due to the higher position of the Metals in the Atomic Table, compared with Carbon, we found that the electrical conductivity of the root-canal implant was improved. A comparative tabulation is as follows:
______________________________________ELECTRICAL CONDUCTIVITYFIBER: OHMS/CM. OHMS/1000 strands/cm______________________________________Carbon 0.36 4.27Nickel coated 0.008 0.10Silver coated 0.004 0.04______________________________________
Gold coated fiber was also used, and this is the most radio-opaque, however, the metal coating can be of any metal cation, with the obvious exclusion of toxic metals and/or radioactive metals, and/or physiologically unacceptable metals, taboo for oral use.
This concerns the use of Gutta Percha from Solvent suspension.
______________________________________Gutta Percha 100 gramsToluene 200 gramsMethylene Dichloride 200 gramsAcetone (or other Ketone) 200 grams.______________________________________
Heat, mix, & dissolve. Use closed mixer in standard fire-proof techniques. The Gutta-Percha Lacquer is coated on to tow, in this case, the same tow used in Example 1, namely Celion� Carbon Fiber 3,000K. The tow is coated in the manner of a wire enamelling machine, slightly modified, modification mainly designed to minimize abrasion of the fibers during handling. The first dip into the lacquer achieves compact rod-form bundling. The second and subsequent dips sizings will build up the coating so that the final root-canal implant conforms to the dimensions used in dentistry namely: (These are the popular sizes)
Gutta Percha "POINT" #5
Gutta Percha "POINT" #20
Gutta Percha "POINT" #25
Gutta Percha "POINT" #35
In this example and its modifications, the carbon fiber tow may be of any number of filaments, from 100 through 12,000 per strand of tow. Furthermore, the tow coated may be a composite of unmodified Carbon fibers and metal-plated carbon fibers, as explained in Example #6.
The Solids material used in solution-coating of Example #6 comprises particulate material: For 100 Grams Gutta Percha substitute:
______________________________________GUTTA PERCHA 50 gramsZinc Oxide 25 gramsInert Color 2 gramsTiO2 1 gram______________________________________
The solids material used in solution coating of Example #6 comprises particulate non-conductive material and particulate conductive material. Particulate conductive material may be used with or without other particulate materials. Particulate material with conductivity is selected from Conductive Carbon Black particles which may be either of Furnace black, Channel Black, Lamp black, or of Graphitic fibers, singly or in any combination.
For the graphitic fibrous particles, the source is Carbon Fiber chopped to a small size. representative materials being:
a. "THORNEL"� Trade mark of the Union Carbide Corp Chicago Ill. 60606 (Fiber chopped to 0.040".)
b. "MAGMAMITE�" Trade mark of the Hercules Corp, Wilmington Del. U.S.A. Fiber marked "MAGMAMITE�", also a trade-mark of the Hercules Corp. Grade used was 1800/AS Chopped 0.250".
These relatively long fiber particles had the unusual result of making a better root-canal implant composition than the pulverised chopped "Thornel�" which had a length of 0.040. The probable reason is that the Magmamite�1/4" fibers broke down during compounding to a satisfactory size, but in so doing, did it in a manner that maintained high conductivity, again postulating or surmising a reason that the slow separation of the fibers did not permit immediate encapsulation by the insulating Gutta Percha.
The coating formula thus is representative of other coating formulations and comprises: (for its solids component)

A straight-through extrusion process is used as an alternative to the coating of longitudinal carbon fibers, which are not used here. The much cheaper and more easy to handle chopped Carbon fibers are used. The chopped Carbon fibers are described in Example #8 above. A compound is devised as follows suitable for extrusion into strands or calendering into sheets or for pelletizing into a molding compound suitable for Injection Molding or for Compression Molding.
______________________________________GUTTA PERCHA 100 GramsChopped Carbon Fiber 5 to 300 GramsZinc Oxide, Lead free 50 to 75 gramsInert fillers for color 5 grams______________________________________
Compounding is effected on a 6"�12" rubber and plastics Mill made by Reliable Machinery Co in N.J. The back roll is faster than the front roll. The rolls are heated to 180 degrees F. The Gutta Percha is thrown on to the mill, the fillers added gradually and the heat on the rolls being maintained to about 250 degrees F. Adiabatic (frictional) heat generates the additional heat. Use Scraper blade to strip off the highly sticky mass. Rolls are closed to 0.010", cooled and the compound is then easily cut off and stripped from the mill roll. Right after stripping the sheets are placed in a multiple platen slab cooler to cool down into a smooth flat sheet.
The compounds with the high percentage of Carbon Fiber to Polymer are used in heavy cross section root canal implants.
Furthermore, the subsequent processing of the compound will diminish the electrical conductivity until the final desired mechanical shape is fabricated. Where much grinding and shredding and mechanical shear is exerted as in extrusion, it is necessary to use the higher percentage Carbon fiber compound. The Final Products are thusly fabricated:
a. By rolling. This is the ancient method of producing the shape referred to in Example 6, where the sizes are given. The flat sheet produced by this example is slit into fine ribbons, about 0.050" wide. A ribbon is immersed into hot water (160 degrees F.), stretched and rolled between the fingers, or through the opening section of a rolling machine. The rolling machine, which may or may not be proprietary is fairly simple. There are two belts, one over the other and tensioned one over the other. One belt moves faster than the other and this differential speed produces a rubbing action which rolls the strip into a rod shape.
b. By extruding. A one-inch vertical extruder is mounted over a tank of cooling water under the surface of which is a conveyor belt. The Gutta Percha Compound is extruded through a spaghetti die as strands. These strands when cooled are dried by a cool air jet and chopped into 11/2" lengths. A Foster-Allen Chopper is preferred from the many in the field. The Vertical extruder is made by Killion in New Jersey. It is electrically heated and thermostatically controlled in the heating zones and in the die-head.
c. By Injection Molding: The compound is chopped and fed into the hopper of the injection molding machine. Cooling time is necessary for a period longer than the conventional polyolefin and usual injection molding compounds, because in the case of this compound it is essential that the material be cooled from the hot state where it is sticky and amorphous, to the cool state when it becomes crystalline and hard. The phase change must take place before the molded point is stripped from the mold.
d. By Compression Molding: Press at 250 degrees F. until the mold halves close. Cool under confinement and remove. Heating is for the shortest time possible. With steam at 100 p.s.i. heating took 15 seconds. Mold was aluminum. Cooling with water at 55 degrees F. took 3 minutes. Press was 9"�12".
This improved root-canal implant has a dual functionality. It retains its rod-form shape and stiffness while in contact with the environs of the apical end of the root-canal and continuously indicates the location and proximity of the apex, even after the gutta-percha is being softened and forced into intimate contact with the interior of the canal, with the action of heat and pressure from the dental compactor. After the filling and compacting process is on the way to completion, the distal end will begin to soften and fill the convoluted minute channels and passageways at the apical end. It retains its electrical proximity sensitivity almost to the end of the operation. To achieve this the central core consisting of carbon fiber filaments is given a primary coat of a resin solution applied and dried thereon. The priming coat comprises a resin which softens at a temperature higher than the enveloping gutta percha compound.
A suitable priming resin is gum Copal which has a long history of acceptance as an endodontic material. This priming resin is designed to melt after the gutta-percha around it melts, and amalgamate with the gutta percha when both are hot. If they are not compatible, as for example when the priming coat is made of collodion, there will be no amalgamation with the gutta-percha. Separation and exfoliation will take place. The Copal core is completely compatible with the gutta-percha. There are other resins which will achieve this dual-functionality root-canal implant. Preferred resins are: (amongst others)
a. Polyterpenes, m.p. 100 degrees C. "PICCOLYTE�"
b. Hydrocarbon Resins-"PICCOPALE�" 85 (85 deg.C.)
"Piccolyte�" and Piccopale� are trade marks of the Neville Co. Pittsburgh PA.
Around the prime-coated special purpose functionality-oriented Carbon fiber tow, are added coatings of a softer (135 F. to 160 F.) GuttaPercha. The Root-Canal Implant will retain its shape when heated and pushed into the root-canal. While the outside Gutta integument is soft, amorphous, thermoadhesive and flowing into the inner rugosities of the canal, the central fiber bundle is shape retentive. The dentist pushes it into the region of the apex, and the position is readable because of the conductivity of the still-intact bundle of fibers. Simultaneously, and "pari passu" the outside guttapercha has achieved softness and adhesion, thermoadhesively, to the inside of the canal at the proximal end of the invented `point`, and the heat is about to reach towards and soften the distal end. Then the distal end will reach its destination and be adhered in the apical area. The heating process amalgamates the inside stiff prime coating on the Carbon fibers with the outside Gutta Percha, and the entire implant will have been sealed in its cavity. The significant proximity-indicating aspect of this modification is that the distal end will not get soft till the near-termination of the operation, and therefore will not fold over upon itself, blocking further progress of the "point" towards the increasingly narrowing channels at the approaches to the apex. This example of the root canal implant may be referred to as the dual thermoplasticity implant, the thermoplasticity of the binder at the central core area being different from the thermoplasticity of the binder on the outside layers.
As a variation it is possible to use the same thermoplastic resin, but in two formulations. The first formulation is of a higher melting point than the second. The second, softer formulation is made by adding plasticizer to the first formulation; for example:
Binder for the central core carbon fibers: Gutta Percha
Binder for the outer part: Gutta Percha 100 parts with Ceresin Wax 10 parts, as plasticizer.
This is a modification of Example #10. The binder around the central core fiber bundle resists heat softening as compared with the outer gutta percha, but this is achieved in a different fashion, by using a binder that is not a thermoplastic resin.
Said binder is an inorganic cement, namely cement such as Zinc Oxide-eugenol. The central core thusly bonded will permit intrusion into the root-canal because of its comparative rigidity under heating even past the temperature at which the outer gutta percha has achieved softening and heat flow under pressure. However the rigidity of the central fiber core is easily destroyed by additional pressure from the dental instrument applied during the penultimate stages of the operation. The formulation thus will be:
Binder for the central fiber core: ZnO-Eugenol
Binder for the outer section: Gutta Percha.
In this example conductive carbon fibers are thermoadhesively impressed into any gutta percha point as continuous filaments extending from proximal end to distal end and on the outside surface of the point. The outside surface need not be completely enveloped by these longitudinal carbon fibers. A few filaments and theoretically a single filament affording contact with an electrical terminal at each end of the point and along its entire length will be sufficient. In practice, and due to difficult conditions of handling these fine filaments, about 10 to 1,000 filaments are used.
A gutta percha point of conventional construction, as is commonly used in dentistry, is the starting material. Around this point is wrapped carbon fiber filaments in spiral fashion, serving as a conductive jacket all around the point. The wrapping is adhered into the outer surface of the point.
This jacketed point will conduct electricity from distal end to proximal end and will thusly have the apical proximity indicating feature claimed in this invention.
100% Solids Dental resin in liquid form: (curable) 100 gm
Chopped Carbon fiber See Example #8: 5 to 50 gm
Chopped metal plated Carbon fiber: (as X-Ray opacifier 2-25 gm.
A thermoplastic point is not used. Instead the fluid composition above, is injected into the root-canal with mild hydraulic pressure, and is converted into its final solid condition by heat or by any accelerator of the polymerisation reaction. What is referred to here as 100% solids resin is a trade term signifying that it is not a lacquer with a large proportion of liquid volatile solvents which evaporate and leave a void in their place. In dentistry Acrylic monomers, beta stage polymers, and other curable fluids are used capable of change from a fluid state to a solid state. One such system, also based on acrylic beta-stage resin appears in Chemical Week Aug. 9, 1978 and consists of "HYDRON�" resin, made by the National Patent Development Corp, New York N.Y. X-Ray photos must still be considered necessary--see column 3 of the work cited--because there is no proximity indicating attribute in the filling material. In this example a dental casting resin is rendered proximity indicating by conversion into a composite comprising conductive Carbon Fibers, for the purpose of filling a root canal.
In this embodiment a precursor sheet is made, and from it the finished points are chopped and rolled to size.

Composition is compounded on a Rubber mill or in a Banbury or in a Masticator, or in a MILLSTRUDER�. A Millstruder� is a combination machine which is able to mix a compound in its mixing section and discharge it through a milling section between two mill rolls which press down and size the material as a sheet the width of the mill rolls. Clearance between the rolls determines the thickness of the sheet. The sheet is cooled and pressed flat. The thickness for the most desired finished points should be 0.010", as the thickness of the precursor sheet. In this state, carbon fiber filaments are laminated or otherwise adhered to the surface of the sheet as threads running mostly in the warp direction. As a modification, cover sheet of gutta percha is laminated or adhered to the top of the laminated fiber sheet thus creating a sandwich of carbon fiber threads between plies of gutta percha. The carbon fibers may be laminated in any direction or even incorporated as random fibers, and not confined to a warp direction. Either the sandwich of carbon fibers or the single ply lamination is then cut into strips the width of the desired gutta percha point size, and rolled into rod form if desired as in example #9. The points made in this way have uninterrupted electrical conductivity of the conductive carbon fibers from distal to proximal ends and are proximity indicative in functionality.
A new dentistry has been created, of advantage to the patient. Root-Canal filling technology has been rendered expeditious, less costly, and with a minimum of X-Ray exposure to the patient. Conductivity of the root canal implant is the enabling means Reviewing the technique of root canal preparation, the dentist during instrumentation of the canal must know when to stop short of the apex. Step by step he enlarges the canal with a metal wire having cutting edges, (a "file") which also gauges and visualises and is visualised by X-Ray in the tooth as to its progression and location and depth. Repeated X-Rays of the file in the tooth are exposed during progression towards the apex. The file being metal is also used to indicate electrical readings which are translated to apical proximity readings. However it cannot go all the way in a dilacerated tooth, in most cases. Therefore the "File" cannot act as proximity indicator in such cases, locating the apex. It cannot act as a flexible sinuously proceeding conductor like the root canal implant herein specified in these specifications. It cannot be left in place. It cannot be heat-softened and adhered and condensed into the root canal, to be left in situ as a permanent root canal implant. Present point has all these modalities available to it. The electrical values attained at the conclusion of the insertion and close to the apex is approximately 40 microamps, for the file or for a silver wire point. The same meter gives the same values for the conductive point herein invented. One measuring device is called "FORMATRON"� made by Parkell in N.Y. A better device is made by Ammident Corp in Pennsylvania. Other methods of electrical sensing and depth measurement are by means of eddy currents or by capacitance, and proximity to the apex can be measured by the very point which will later be heatsealed into the canal. Instead of a metal "file", as stated, a silver point may be used for proximity indication in the same way as metal file or the specified invented root canal implant is used. Silver wire point may indeed be left in the canal as a point and used in a manner similar to a gutta percha point. There is a defect inherent to the silver point however. It cannot be heat sealed in place. Objections may be catalogued thus:
Objection #1: The silver root canal implant is not thermoplastic nor is it thermoadhesive. It cannot be softened in the canal.
Objection #2: The silver root-canal implant will not make intimate contact with the inside of the root canal cavity, and therefore will permit the flow of bacteria past it and into the region of the apex Therefore the silver implant ("wire") must be cemented into place.
Objection 190 3: A cement, or dentally accepted Zinc Oxide-Eugenol is used, but is not efficacious because it does not lute the silver intimately to cementitious paste, and again fissures, cracks, passageways will form between the silver point and its peripheries and the rugosities of the root canal in which it has been cemented.
Objection #4: The silver point cannot be drilled out for a metal post preparation where indicated conditions for post exist.
Objection #5: The silver point is subject to galvanic corrosion in the electrolytic ambience of the oral cavity.
In answer to objection #1 above:
Invented point is thermoplastic and thermoadhesive. It can be softened to an adherable condition to bond to the inside cavities of the canal.
In answer to objection #2 above:
Invented root canal implant makes intimate adhesive contact with the irregular surface configuration of the canal. No bacteria can flow past it.
In answer to objection #3 above:
Invented point is highly conforming and heat-adherable. An interface of an incompatible cement is not needed. If Zinc-Oxide-Eugenol paste is used as a lining of the cavity, the softened adherable implant of this invention will amalgamate with the exposed profile of the surface of the cement pushing it strongly into the walls of the canal.
Heat-softening of the invented point is by conventional heating or by endogenous heating which occurs upon the application of external power. Silver points cannot be heated and if heated will serve no useful dental purpose. Silver is not thermoadhesive like a thermoplastic resin is.
In answer to objection #4 above:
Invented implant can indeed be drilled out for later post preparation. Drilling out is almost better and quicker than drilling out conventional gutta percha points, due to the presence of carbon fibers.
In answer to objection #5 above:
The carbon fibers comprising invented root canal implant are not subject to galvanic corrosion. They are extremely chemically inert. They provide in addition a conductive ambience within the canal contiguous to the canal walls. This conductivity is true tissue conductivity from wall to wall, whereas the silver point, which is conductive per se, does not provide a complete conductive ambience due perhaps to corrosion, insulation of its outside surface by the luting cement. It is accepted that a conductive environment is tissue-friendly. Known gutta percha points are non-conductive. Present invented gutta percha point is conductive.
In summary:
No dental implant in the endodontic root canal art provides the mechanical strength of the fibrous reinforcement, the fibers being inert chemically and biologically, the fibers being conductive, and the implant being proximity indicative when measured by instruments known and readily available. It can be heated from end to end or sectionally in any sectional part. It can be heated by electrical resistance within the tooth during the operation or outside the tooth. It can be heated ultrasonically within the tooth during the operation.
Sources of supply of carbon fibers:
Carbon fiber as used in this invention may be from any precursor base carbonaceous material, including, polyacrylonitrile fibers, Pitch; Cellulose; Coal. Composition of the fiber is not relevant as long as it has conductivity and chemical inertness.

Gutta Percha Equivalents: For the purposes of this invention, use:
Gutta percha is the trans polymer of Isoprene. It is a naturally occurring polymer, PALAQUIUM GUTTA. It analyses as 90% Hydro carbon for the best grade from Malaysia. An inferior grade is known as balata and is familiar in golf balls. It comes from a related tree in South America, MIMUSOPS BALATA.
Both Gutta percha and Balata may be used, separately or mixed in any ratio, the higher the Balata, the softer the mass.
This is the trans polymer of Isoprene and is a synthetic product. It is sold by Polysar Corp, Sarnia, Ontario, Canada under the trade name of "TRANS PIP PP 301"�
1. Thermoplastic polymers of acrylic monomers, e.g. Butyl Methacrylate, Isobutyl methacrylate, mixed methyl methacrylate polymers
2. Styrenic block polymers, such as SBS, SIS,S-hydrogenatedbutadiene-S
3. Polyester thermoplastics, such as "Santoprene"� sold by Monsanto Co. Akron Ohio
4. Ethylene polymers and terpolymers
The precondition is thermoplasticity corresponding to the range of gutta percha to which dental techniques are adapted by ancient usage, and also freedom from physiological irritants. The contained carbon fiber in the finished thermoplastic implant being very chemically inert will not contribute to the catalytic breakdown of the polymer, to reversion, to embrittlement and the like.

The Surprising Things You Find at Twice Sold Tales
From the back of "Bitter Harvest,â an exposé on the real Cesar Chavez published by Orange Tree Press in July of 1970:
JOHN STEINBACHER, according to an editor of the Christian Science Monitor, is a "National Phenomenon.â
After five well received books, he suddenly emerged from his role as an everyday reporter to become nationally famous for his sensational "Charter Houseâ expose. His investigative report of a secret session for subverting America's youth by leading educators and professional sexologists was subsequently reprinted all over the nation in the millions of copies.
Since then, his School and Family column in the Anaheim Bulletin has resulted in nationwide fame for that newspaper.
A school teacher for 10 years, he spent seven years as a social worker in Los Angeles. In 1968 he worked with Walter Winchell on the Sirhan case, and from that came the book, "The Man, the Mysticism, the Murder.â
Steinbacher has written scripts for motion pictures, including "Pavlov's Children,â and is the author of numerous LP recordings, including The Child Seducers narrated by the famous screen star, John Carradine.
His Charter House series should have won him the Pulitzer Prize for exceptional investigative reporting, and probably would have if he had written a story favorable to the participating conspirators.
BITTER HARVEST has been acclaimed by professional editors and publishers as his finest achievement. Simple and direct in style, it manages to carry in its pages all the moving eloquence of a masterpiece.
With BITTER HARVEST, Steinbacher has written his own introduction to literary immortality.
Dear ol' uncle Johnwho knew you were such a Renaissance Man?

Powerline communications (PLC) is a favorable technique for many smart grid applications. By transmitting information over the existing powerline infrastructure, PLC has the benefit of low deployment cost. However, due to low transmit power, limited bandwidth, and harsh channel conditions, reliable long-distance and high-capacity PLC is challenging. Relay-aided (RA-) PLC is promising in addressing these issues. In this paper, we investigate the performance of the amplify-and-forward (AF) RA-PLC system from an information-theoretic perspective. The capacity of AF-based RA-PLC is analyzed for frequency-selective PLC channels. The capacity bounds are derived, and the optimal power allocation between the transmitting nodes and the optimal power distribution over the signal frequency band are obtained. The capacity benefits and features of AF-based RA-PLC are evaluated with two prevalent powerline channel models. Based on the signal attenuation model, the capacity of AF-based RA-PLC is compared with direct-link (DL-)PLC, and the effect of relay location is revealed. In addition, based on the transmission line (TL) model, the effects of branch density and load impedance on the capacity of AF-based RA-PLC are evaluated.
