Ronald Matsuura, D.D.S
Call (408) 354-1717
Though dental implants are a great option for restoring multiple missing teeth, it's also a perfect solution if you're missing only one tooth. In that case, Los Gatos's Dr. Matsuura can implant a device in the jawbone surrounding the missing tooth which serves as a replacement for a tooth root and an individual crown. This unique solution is referred to as a single-tooth implant crown.
Once in place, the implant crown looks, feels, and functions like your natural tooth. It's cleaned and flossed just like your other teeth, and unlike bridges or other restorations, you don't need special tools to clean around your new tooth. You will need to practice effective oral hygiene, however, and the friendly staff at Ronald Matsuura, D.D.S will be happy to talk to you about caring for your mouth.
For more information about dental implants as a replacement for a single tooth—or to make an appointment with Dr. Matsuura—call Ronald Matsuura, D.D.S today at (855) 548-8465.

The blueness of a wound cleanseth away evil: so do stripes the inward parts of the belly.

Luke 11:40-41
Ye fools, did not he that made that which is without make that which is within also? But rather give alms of such things as ye have; and, behold, all things are clean unto you.

For meat destroy not the work of God. All things indeed are pure; but it is evil for that man who eateth with offence.

Should we ban cheap booze? Or tell medics, and now church leaders, to mind their own business and leave how much we drink and what we spend to us?
Doctors argue they are minding their own business. Our health is their business. And right now the nation's health is in freefall because, medics warn, the drop in drinks prices, and the rise in stress levels, tempts more to stock up and swig more of the stuff at home.
Blackpool has the highest rates of chronic liver disease in the country and one of the lowest life expectancies, particularly for men.
Blackpool's director of public health, Dr Arif Rajpura supports strategies for imposing a minimum price policy on alcohol – below which prices must not fall – contending: "Cheap alcohol is costing the NHS dearly." There's also concern at numbers of younger drinkers pre-loading, drinking more at home, before going out, generally later, to top up.
Now the Methodist, Baptist and United Reform Churches have added their voice to health professionals calling for minimum prices on alcohol – after a survey highlighted the impact on communities of so-called feral kids getting smashed on cheap booze and running amok.
Ruth Pickles, vice president of the Methodist Conference, says: "We want a minimum unit price – not a minimum cost price which is what the government has agreed."
Critics say loss leading cheap beers and spirits marketed by discount outlets, supermarkets and bar owners are partly to blame for the rot in health – and social standards. Yet the footfall has fallen just as assuredly at churches as it has at community pubs, signs of the times seen in the numbers of churches as well as pubs shut.
Health secretary Andrew Lansley, who is preparing to launch a new year drive aimed at ending the country's binge drinking culture, concedes deep rooted drinking habits won't be curbed by a rise in the price of booze.
"The causes of binge drinking are too complex to be solved simply by raising prices," he says.
"Alcohol consumption and alcohol misuse are not on a straight line to each other. Are we saying because a bottle of vodka isn't £8 but £12.50 they won't preload with vodka for a night out when they are in clubs where they pay £5 for a drink?
"They're still going to binge drink because it's a behaviour issue."
With the jingle of tills accompanied by the jangle of bottles in supermarket trolleys shoppers are rattled by moves to ban cheap booze. Blackpool office worker Sarah Dawson, who stocks up as Asda, says: "Oh, give us a break. Drink is part of the spirit of Christmas.
"I've not had a girls' night out for ages, we're not having an office party, and we're working to silly o'clock each day.
"We'll probably all relax by having a drop too much.
" I look for deals on supermarket comparison sites then hit the shops but I never leave with just drink in the trolley."
Mike Mason, 24, of Llandudno, working as a contractor in Blackpool until April, swoops on six boxes of brand name lager, two for £16, at Sainsbury's, to stash for Christmas at the seafront flat shared with three other workers, who have stocked up on Becks and Stella.
"Do the maths," says Mike. "£16 for two, normally £13.99 for one, 15 bottles, 275ml. It brings it down to about 50p a bottle. Sorted..."
Plea not to punish the pubs...
Blackpool Pubwatch chairman Craig Southall (right) argues it is time for all elements of society to put their houses in order - but not at the expense of the drinks trade.
"We've put up with enough," he adds. "The way forward is through education not eradication. Right across society. Get to the kids faster. Re-educate drinkers.
"Take it from me, if minimum pricing is forced through it may be 50p this year, 60p next, and before long it will be £3 for a half lager, so don't say you weren't warned, and pubs will be priced out of existence.
"We need to find the fundamental root causes of why people drink to excess, rather than what they drink or how much they pay.
"Petrol prices have gone up but people haven't stopped driving. People who drink will always find money for drink.
"Whatever happens supermarkets will win. I buy my own drink there to drink at home, but also spend on food. But if you want an experience, and not just a drink, go out to a pub ... and that's what you're paying for, the surrounds, a manager looking out for you, entertainment, atmosphere, meeting other people and not sitting at home socially networking with a bottle of cheap lager. We're losing out on real community spirit."
Craig, licensee of town centre Yates, says publicans are coping with a double whammy of reduced office parties and the loss of Friday as the definitive night out because of longer working hours or shorter cash.
He adds: "This Friday represents the first big Friday night out in ages because most want a clear head for Christmas Day.
"Saturday's taken over as the big night out."

Unveiling the Beauty of Statistics
At Brandt Ronat and Company we are often tasked with presenting data in a compelling manner, so we're always on the lookout for new programs, methods and designs to inspire these visualizations.
One such thing is Gapminder's Trendalyzer. The Trendalyzer is an extremely powerful tool for understanding the world through a variety of indicators over a long period of time. Its ease of use belies its depth, which is why I'm writing this article now and not in 2008…
I first saw the Trendalyzer in action in late 2008 when I watched Hans Rosling's TED presentation Debunking Myths about the "Third World". I was captivated by his moving circles, so when I found out I could play with that very tool I rushed over to the website to give it a try.
I looked at a few different indicators for several minutes then went back to work and forgot about it until the other day. I received a tweet with a link and the words "Perhaps best graphical use of data on the Web". So in hope of discovering something astounding I could share with co-workers and clients, I clicked and found my self back at Gapminder.
Since 2008, I've had a greater need for having a variety of visualization solutions in my bag of tricks, so I decided to take another look. It turns out they were wrong.
It's not just the best graphical use of data on the Web, it is the most intuitive way to visualize multiple data sets over time.
To do this, Trendalyzer charts each "entity" (often a country) using color, size and movement.
One great thing is that all the parameters for the graph are pulled from the URL, so it's easy to share the same setup with others.
For instance, I made a chart that explores the relationship between a country's infant mortality rate, its life expectancy, its income per person and its total fertility.
I have tracked USA and China, so their paths will be displayed as trails of points, while the other countries are transparent. Infant mortality is measured on the x-axis, total fertility on the y-axis, life expectancy by color of the point, and total income by the size of the point. If you press play (at the bottom) the time line will begin and the points will move and grow as time moves along.
They have many different indicators that you can have displayed by one of the 4 dimensions (axes, size, color), making this a very powerful, but very intuitive way to present a lot of time-based data.
Another cool thing they have is Map view:
Map view puts the points on a map of the world and allows 2 indicators to be measured by size and color.
Their main goal in making this data and software available is to fill a data gap between people who want to explore this world data, but don't have access to it, or can't interpret it in its raw forms. They're also hoping that access to this data will make falling back on assumptions, stereotypes and common sense unnecessary.
Google purchased the software behind this and they offer it free of charge.
I haven't tried using the Google version and uploading my own data yet, but I'm looking forward to getting a chance to try it out.
The main thing to remember is that it's hard for raw figures to inspire someone. When you allow a user to explore your data in a way that's relevant to them, you can easily get them energized about your cause. Would you rather look at this and this or have those numbers come alive like this?

Lawyer in Milford on Sea
You may not believe it, but a simple visit to your local high street can be fraught with dangers. Here are just a few examples of the types of accidents that can occur in shops in Milford on Sea:
- Accidents caused by products falling from shelving, usually as a consequence of incorrect stacking techniques;
- Accidents caused by absentminded supermarket staff who fail to look out for customers when moving items through the aisles on large trolleys;
- Slip, trip and fall accidents caused by spillages; and
- Accidents caused by hazards such as leaking fridge-freezers.
If you have been injured through no fault of your own, you must report your accident to the shop's owner and fill out an accident report form. If the shop's owner insists on completing the form on your behalf, you must read their entry carefully to ensure that the record accurately reflects the nature and severity of your accident. If the record is not entirely accurate but you sign to confirm the details provided, you may jeopardise your chance of securing the compensation you deserve.
An accident lawyer in Milford on Sea can advise you of your legal rights

Skip to comments.Prayer Req MarySecretary & Kidney Transplant Success Praise Thread
Posted on 11/06/2009 9:12:38 AM PST by JoyaEdited on 11/07/2009 7:02:50 AM PST by Admin Moderator. [history]
PLEASE continue to pray for MarySecretary and her recovery from a successful kidney transplant operation.
THANKS to everyone who has prayed. Please continue.
Here's some comments off of FB:
From: Jerry S. Subject: Mary's Surgery Date: Friday, November 6, 2009, It is 4:45 am we just got home the hospital; Marys surgery went well, she now has a new kidney and the doctor seemed please with the results. Thank you very much for your prayers and please keep them up because there is a long road to recovery, also keep Richie in your prayers that he can get some rest. You prayer warriors are much appreciated, may Gods blessing be upon you. Love pastor Jerry
+* +* +* +*
From: April T. Subject: Mary Date: Friday, November 6, 2009, 8:41 AM I called the hospital this morning. They just brought Mary into her room a little before 8:00. Due to the out break of H1N1 in the area visiting hours are restricted to 12:00 - 8:00 p.m.
Also, children under 17 are not allowed to visit at this time. They also ask if anyone with a runny nose or flu type symptoms would not visit the hospital.
The nurse did not have any other information for me, other than Mary is very sleepy now. (That is quite understandable).
I stand amazed at the talent God has given to man, to even make such an operation possible.
May our prayers continue to seal Mary's healing.
Blessed are Thou HaShem our G-d, King of the Universe, Who heals the sick!

Mary, may God rest your soul in peace.

Our oldest daughter and oldest of all the kids. I am so proud to be her mother and to enjoy watching her grow up. She not only looks like her daddy but is just like him. Social, fun and outgoing! She is such a huge help in this family and I rely on her so much! I miss her when she isn't around. She is a sophomore this year and I can't believe it!
Our oldest son! Jaylen is going into 5th grade. He is our sports kid, always loves to throw around any time of ball! He has a sweet personality and is the quiet one of the bunch, like his mom! He loves his cousins and helps to take care of the youngest ones. He will be a great daddy one day!
Our youngest son and middle child, he is the loudest of the bunch. He is so full of personality you know when he isn't around. Being the life of the party people are drawn to him. But beware he LOVES to tell stories! We call him our Preacher because has a 3 point sermon every time her talks! He is in third grade.
Our girly girl! Since she was little she loved shoes, dresses and skirts. She wanted to dress up wherever she went. Now she is getting into lip gloss and I have a feeling makeup will be an issue sooner than we did with Aryianna. She has such a sweet side but can stick up for herself in a group of five! She is in second grade.
Our youngest daughter, youngest child. The baby of the group. She loves being the baby as well. She has taken after her sister, Akayla-Joy in that she loves to dress up wherever she goes. I love her little dimples and hope she stays little just awhile longer. She is so excited to start Kindergarten and go to school with the rest of the kids this year!

Cleveland Facebook murder suspect Steve Stephens hunted across US.
Facebook vowed to "do better" after the social network unwittingly played host to a series of disturbing videos that culminated in the shooting and killing of an elderly man.
The social networking titan said on Monday it will review its "reporting flows" so that people can flag video and other content that violates its standards. It's also exploring technologies like artificial intelligence to help prevent these videos from being shared in their entirety.
The suspect, Steve Stephens, 37, on Sunday posted videos of both his intent to murder someone and then the act itself. He later went on Facebook Live to discuss the killing, according to CBS News. Cleveland police say a nationwide manhunt for the suspect is underway. Police identified the victim as Robert Godwin Sr., 74.
Who is the suspect?
Stephens works as a case manager at Beech Brook, which is an Ohio-based behavioral health agency that serves children and families, according to the Associated Press. Williams said Stephens has "a lot of traffic violations" but no criminal record. Stephens is also affiliated with the Omega Psi Phi fraternity, the AP reports. Beech Brook spokeswoman Nancy Kortemeyer said in a statement to the AP that the agency was "shocked and horrified" by the killing.
Stephens is considered "armed and dangerous" and appears to have "deep, deep issues," Williams said. The woman who is mentioned in the video is "safe" in an undisclosed location, according to police. She is among several people who have cooperated with authorities in the investigation.
Investigators were able to have a brief phone conversation with Stephens early in the investigation, Williams said. Authorities urged the suspect to turn himself in for the "heinous crime."
Stephens is wanted on an aggravated murder charge. The 6-foot-1 man was last seen wearing a dark blue and grey or black striped polo shirt and driving a white Ford Fusion.
The grisly videos are just the latest incident in which Facebook has dealt with disturbing content that has been broadcast to its site, available for users to share and comment on. The company envisioned live video as a tool to bring people closer together, but the dark, unexpected consequence has been the raft of suicides, rapes and murders that have appeared on the site.
Facebook's role as an arbiter of this content came into question when two graphic videos played a critical role in the Black Lives Matter movement. Other disturbing videos on the platform include four people in Chicago being charged with hate crimes in January after they apparently beat and tortured a mentally disabled man. Also in Chicago, police are still searching for those involved in the alleged gang rape of a teenage girl last month. Dozens reportedly watched the assault live on Facebook.
On Monday, Facebook said it disabled Stephens' account within 23 minutes of receiving the first report about the murder video, and two hours after receiving a report of any kind.
"But we know we need to do better," Justin Osofsky, vice president of global operations, said in a blog post.
The company said it didn't get a report about the murder video until more than an hour and 45 minutes after its posting, and never received a report about the first video. It only received a report of the third video, a Facebook Live video, after it ended.
Facebook added that it has thousands of people reviewing millions of items every week. "We prioritize reports with serious safety implications for our community, and are working on making that review process go even faster," he said.
Facebook also shared the timeline of events:
11:09 a.m. PT: First video, of intent to murder, uploaded. Not reported to Facebook.
11:11 a.m. PT: Second video, of shooting, uploaded.
11:22 a.m. PT: Suspect confesses to murder while using Live, is live for 5 minutes.
11:27 a.m. PT: Live ends, and Live video is first reported shortly after.
12:59 p.m. PT: Video of shooting is first reported.
1:22 p.m. PT: Suspect's account disabled; all videos no longer visible to public.
Syracuse University professor Roy Gutterman, an expert on media laws and free speech, said Monday that with nearly 2 billion users, he doesn't know whether the social network will be able to prevent more violent videos such as the Easter Day shooting from appearing.
"I don't care how many algorithms you employ, you're not going to be able to catch everything," he said. "People are surprised by the violence we see, but it's the world we live in now."

Check with the architectural engineering department for course registration deadlines, and construction materials program requirements. Please use the form above to request admissions info for Sauk Valley Community College.
Architects spend much of their time in offices, where they develop plans, meet with prospective clients, and consult with engineers and other architects. They also visit construction sites to prepare initial drawings and review the progress of projects to ensure that clients are satisfied. About 1 in 5 architects were self-employed as of 2017, and the average salary for architects was $76,100 annually.
There are typically three main steps to becoming a licensed architect: completing a professional degree in architecture, gaining relevant experience through a paid internship, and passing the Architect Registration Examination. A typical bachelor's degree program includes courses in architectural history, building design using computer-aided design and drafting software (CADD), structural engineering, construction methods, and professional practices. The design studio is a central component of most architectural programs, where students apply the skills and concepts learned in the classroom to create drawings and three-dimensional models of their work. Beyond major requirements within the architectural engineering department, you may consider Wake Tech automation as a complementary elective to your primary course of study.

text: Why do we love holidays so much?\nOther than the obvious (all the delicious food that will be eaten), it's always a fun occasion to dress up, do your hair and makeup, and be all glammed up! In today's blog post, we collaborated with our beautiful friend Missy Sue to show you a really simple yet beautiful holiday hairstyle: the french braid crown.\n\nThis hairstyle looks intricate, yet consists of simple 2 french braids put together with a hair accessory. Missy also added a few wefts of her clip-in Dirty Blonde Luxy Hair extensions for extra length and volume - this is, of course, optional - but hair extensions make this hairstyle so much more dramatic because of that extra 'oomph'. If you're not too familiar with them, check out this blog post. \nWatch the video below or scroll down for step by step instructions on how to create this beautiful and glamorous holiday hairstyle:\n[video url="https:\/\/www.youtube.com\/watch?v=coSEkui_qec"]\nHow to: French Braid Crown\n\n\nPart your hair as you desire - it can be a deep part, or a middle part.\nStart to french braid your hair on one side until you reach your ear. To learn how to french braid, check out this youtube video. \nOnce you reach the ear, continue doing a regular three strand braid all the way down with a small section of hair, like this: \n\nCriss cross two bobby pins at the end of the braid, so that it doesn't unravel while you work on the other side, like so: \n\nRepeat the exact same step on the other side - french braid until the ear, then regular three strand braid all the way down. \nAll is left to do is criss cross the two braids at the back, like a crown, add in your favorite accessory and you're done! \n\n\n\n\n\n\n\n

SHEU 2 [IF 3 I may M EHNOVENTORS 055 DAN/6 E. 540%50/14, J6 BY r I APPARATUS AND METHOD FOR SIMULATING SPACECRAFT EROSION subjected to extremely severe temperature and heating conditions while moving at very high velocities relative to atmospheric gases, dust, rain, ice particles, vapor, micrometeorites and the like. The effect on heat shield materials, antennas, optical windows and the like surfaces when contacted and eroded by such material is of particular interest and importance to spacecraft designers and operators. Heretofore, to obtain experimental data, reliance has been placed to a high degree on telemetered information relayed from actual spacecraft to ground stations. Such results are obtained at high cost in time, equipment and human effort. Furthermore, only extremely fragmentary and limited results are obtainable and securing these is determined largely by chance.
in view of the foregoing it is a primary purpose of the present invention to provide simple, effective, highly reliable ground-based. equipment operable under predetermined conditions repeatable at will for testing erosion resisting capabilities of a wide variety of materials under any of many selected exit or re-entry conditions simulating trajectory conditions of spacecraft including changing pressures, altitudes, attitudes, temperatures, heat transfer, wind and skin fric-, tion loads, ablation, densities, and velocities. For this purpose there is provided a high strength chamber capable of being evacuated to any desired degree. Any selected test object or material is supported for index ing movement successively into the flow path of independently operable high velocity accelerators. Each accelerator is operable to impact the test object with gas and/or with selected particulate at a desired velocity after the test surface has reach a temperature and a heat transfer rate corresponding to that calculated to exist under an assumed selected condition; The very high temperatures and heat rates involvedare produced by various gas heaters including the unique plasma generator means disclosed herein located in the evacuated chamber. Desirably, the heatermeans incorporates provision for initiating and controlling its operation including means for shielding the test object from the generator until its operation has reached a desired level. The particle and gas accelerators are arranged in an array about a focal point occupied by the test object-which is arranged to bestationary or indexed into successive alignment with the individual accelerators whereupon the latter is automatically activated. The accelerators employed to accelerate particulate onto the test object preferably include a support forthe particulate downstreamjfrom the pressure generating chamber, the outlet to the latter being closed by a burst diaphragm. Provision is made for 2 catching the diaphragm debris thereby eliminating any possibility of the debris impinging on the test object.
Accordingly, it is a primary object of the present invention to provide an environmental erosion simulator for testing the effect on various materials and objects traveling in the atmosphere or in space. including exit from and re-entry into an atmosphere such as that surrounding the earth. 1
Another object of the invention is the provision of apparatus and a method for determining the ablative and erosion effects produced thereon under various environmental conditions and for'recording and observing the effects produced upon encounter with gas and/or particulate.
Another object of the invention is the provision of environmental simulator apparatus including a plurality of-individual accelerators together with means for indexing a test surface successively into the path of an individual accelerator and for thereupon activating that accelerator.
Another object of the invention is the provision of environmental simulator apparatus including means for reaching the desired temperature and heat rate of the test object and thereupon subjecting the heated surface to collision with selected particulate under pre-selected accurately known conditions and for recording the results produced before subjecting the surface to collision with other known particulate.
Another object of the invention is the provision of a novel apparatus and methodfor simulating the exit or re-entry of a test object into a planetary atmosphere while recording the effects produced on the surface under a succession of different pre-selected conditions.
Another object of the invention is the provision of environmental simulator means including means for passing a test object through an excursion traversing-a pre-selected series of conditions of differing types.
Another object of the invention is the provision of environmental simulator means by which the erosion effects produced on a test object can be determined and recorded while the test object follows a prescribed path under pre-selected conditions.
Another object of the invention is the provision of environmental simulator means for simulating the passage of a test object through a variety of different environmental conditions and including means for determining the velocity of different kinds of particulate impacting the test object at different times during a single test cycle.
Another object of the invention is the provision of simulator apparatus for simulating encounter of a test object while heated or cooled with successive increments of particulate at known velocities and of known mass and at known time intervals.
v Another object of the invention is the provision of unique apparatus and method of simulating a partial or .complete trajectory of a spacecraft in flight and recording a wide variety of conditions and effects produced .thereon under pre-selected conditions,
simulated space environmental conditions and regulatable to heat test objects to temperatures and heating rates produced by wind and skin friction loads acting on missiles, spacecraft and the like traveling at velocities including the hypersonic range.
These and other more specific objects will appear upon reading the following specification and claims and upon considering in connection therewith'the attached drawings to which they relate.
Referring now to the drawings in which a preferred embodiment of the invention is illustrated.

The lower end of the shaft is coupled to a driving motor 28through gearreduction means 29. Also sup ported on theouterend of shaft is a rotary switch designated generally having a contactor 31 fixed to shaft 26 and effective 'to bridge a pair of axially aligned contacts 32, 33 at each index position. It will be un-. derstood that there is a pair of contacts 32, 33 for each of the gas accelerators and that these contacts are mounted in a ring 34 of insulating material.

FIG. 6a is' a fragmentary cross-sectional view of an alternate trigger system for firing the acceleratorrand FIG. 7 is a cross-sectional view taken along line 77 on FIG. 3 showing details of the particulate discriminator;
FIG. 8 is an elevational view,largely' in cross section, of another preferred embodiment of the invention;
FIG 9 is a top plan viewgon a reduced scale of FIG. 9;

FIG. 11 isa'fragmentary cross sectional view on an enlarged scale. taken along 1l-.-1l on FIG. 10 and showing details of typical impact craters.
Referring initially more particularly to FIG. 1, there is shown a typical spacecraft 10 in flight with its heat shield andheat sink 11 located foremost. Emanating from the rim'of the heat shield are the usual primary and secondary shock waves 12, 13. Not shown, but
' technique for subjecting shields such asfll and other exposed objects and surfaces to conditions substanshown in FIG. 5 is found particularly advantageous but tially identicalwith the conditions.experiencedvif actually' traveling along aparticular assumed trajectory. One; preferred embodiment of such asimulator-apparatus is designated generally 20 in FIG; 2. As there shown, the apparatus comprises, a high strength thicklocated'close to the center, of main housing 21. It will Housing 21 is equipped with an operators access port 33 of any suitabletype closable in an airtight manner by a cover 34. It will be understood that access port 33 may be positioned in any convenient location and usually along the lower side of housing 21. Another port is equipped with an optical window 35 shown in phantom lines in FIG. 2, and in full lines in its proper position in FIG. 5. Port 35 includes a high strength window 36 for use by an observer, an optical pyrometer or a recording camera, both representedschematically at 37 in FIG. 2. The optical port 35,36 may be located at the most advantageous position for viewing the test-s urface at the various'indexed positions occupied thereby during a particular test run. The window position it will be understood that other positions may be used and, if desired, additional observing ports may be provided.
Rigidly clamped to the upper end of the indexable retracted position indicated in dot-and-dash lines. A
second bracket 44' clampedto'the top of shaft 25 includes anjupright leg 45 here shown as formed of angle iron. Brackets 44, 45 support a suitable gas heater designated generally 46 for the testobject.
It will ,be understood that, for certain test runs. a suitable storage type heater of either the chemical or electrical type may be used particularly for lower velocity tests in the sub and supersonic ranges. Under these conditions well-known storage type heaters are adequate whereasat higher velocities it is preferred to use the novel plasma jet heater disclosed in detail herein and to be described presently.
Bracketarm 45 is provided with a discriminator 47 having details best shown in FIG. 7 and adjustably .clamped to bracket 45 by screws 48. The discriminator includes a small port-49 in alignment with a somewhat larger bracket port 50. By selecting a proper size port 49, the operator can restrict the. number and distribution of particlesallowed to pass onto a test object from a. particular particle accelerator.
Referring now more particularly to. FIG. 3,.it will 'be understoodthatthe plasma jet heater. 46 has a massive cooled or uncooled copper body-52 clamped. to the upper end of bracket 45 by'a clamping nut 53. Snugly threaded into the upper end of bodySZ by threads 54 is a sleeve of insulating material 55 supporting a cooled or uncooled tungsten or similar electrode 56,- The Outer. end of this electrode 7 is .provided with an enlarged threaded portion 57 removably seated in'sleeve 55 and havin'g'a'kerf 58 to facilitate disassembly. cooperatingelectrode 60 .is'mounted in abore 61 of sleeve 55 and connected via lead 62 to one end of a transformer secondary coil 63, the other end of the latter being con nected to electrode 56 via conductor 64. A capacitor- 67 is connected across secondary coil 63 and the transformer primary coil 68 is connected to a suitable power supply. When the transformer is energized, a high intensity spark 69 is created in the conical space 70 between the end of electrode 60 and the adjacent surface of electrode 56.
-Any suitable gas, as for example, hydrogen, nitrogen orargon can be introduced tangentially into conical chamber 70 via supply conduit 72. Thisrapidly spiraling gas flow, aided by the rotational effect produced by the rotating flux field created by current flow through coil 74, generates a high-efficiency, high-temperature supply of plasma which is accelerated to high velocity while expanding through the venturi-shapedpassage 75. This passage is formed axially of a copper nozzle 76 threaded into the outer end of main body 52. The temperature of the issuing plasma jet may be controlled and cooled by injecting a non-reacting gas, as nitrogen, or be greatly increased by intermixing a combustible component, such as hydrogen, supplied via 72 with an oxidant, such as oxygen, supplied into the throat zone of venturi 75 via supply conduit 77. Ignition of this combustible mixture, if required, is by an igniter 78.
The operation. of the plasma jet heater is highly flexible, the heater being capable of producing a wide range of temperatures depending upon the electrical energy input and the particular types and quantities of gases introduced viaconduits 72, 77. Forexample, hydrogen and oxygen combust to produce temperatures .up to a maximum of about 5 ,000 F. The plasma jet can be operated alone or in combination with combustible gases and is capable of producing the temperatures required for test purposes. When operating as a plasmav jet generator, electrodes, 56, 60 are suitably energized,
as for example, with 25,000 volts A.C. Coil 74 produces a rotating magnetic flux field in the vicinity of the electrodes and is energized as shown with one side of the coil being grounded via lead 90 to the main body of the generator and its other side connected 'via required power supply 91 and lead 92 to electrode 56.
Referring now more particularly to FIGS. 2, Sand 6,
there willbe-described a typical one of a plurality of gas opening into the interior of'housing 21 in desired alignment with the surface of the object to'be tested mounted on the axis at the inner end of shaft 26.
- Referring now to FIG. 6 there is showndetails of means for generating high pressure gas to activate the particle accelerator. Detachably secured, as by threads 100, to the inlet end of passage 99 is coupling 101- having a T-shaped passage 102. One end of the T-head of passage 102 forms a 'debris collector chamber whereas the opposite end comprises the outlet from a'small but high pressure gas chamber 104 extending axially of the thick walled housing member 105. Member '105. is threaded to outlet passage 102, the latter being normally sealed closed by a gas-tight, burst diaphragm 106. Sealed in the opposite end of pressure chamber 104 is an electrode 108 seated in the bottom of a deep cup-shaped Nylon bushing 109. Electrode 108 extends to the exterior of member and is suitably clamped in an assembled position.
A bank of heavy duty capacitors is chargeable from a high voltage DC power source, not shown, and has one lead 123 connected by nut 124 to the outer end of electrode 108 and its other lead 125 connected to body member 105 of the pressure generating chamber 104.
A solenoid 128 (FIGS. 2 and 6) is rigidly supported on a bracket 129 fixed to the main body 105 of the pressure chamber and its coil ends are connected to leads 126 and 127 to a power source 129 and to contacts 32, 33 of the rotary switch assembly 30.
Referring to FIG. 6 it will be understood that armature 132 of solenoid. 128 is normally positioned with its outer end extending across the outer end of a metal plunger-133 having a sliding gas-tight fit with bore 134 through the wall'of body member 105. The inner'end of plunger 133 is equipped with a Nylon extension 135 providing the support for the upper end of the teaser wire 136 having its lower ,endconnected to 'thecenter -of electrode 108. Under these circumstances, the
sure in chamber 104 acts to extend plunger 133 and brings teaser 136 into contact with the side wall of chamber 104 to complete a discharge circuit for the highly charged bank of capacitors 120. The abruptly released energy creates a large arc centrally of chamberll04 and this energy instantly creates a great temperature and pressure rise in the gas held captive in the chamber.
Referring to FIG. 6a, there is shown an alternate firing mechanism for the accelerators 95 which is simpler and avoids the time lag and inertia delays inherent in the electro-mechanical firing or triggering mechanism described above in connection with FIG. 6. The same or similar parts are designated by the same reference character distinguished by a prime. It will be noted that the upper end of teaser wire .136 is suitably secured to thesidewallof bore 104, as by anchoring it beneaththe rim of the burst diaphragm. The fast action firing switch comprises-a glass tube provided with electrodes 'l6l, 162 projecting toward one another and sealed within the opposite ends of theswitch tube 160. A third electrode 163 projects throughthe tube wall between electrodes 161 and 162. The latter are connected lead 123 between capacitor 120 and a terminal leadingto the lower end of teaser wire '136. The third electrode 163 is connected to the output lead 164 of a sequence timing device 165, it being understood that this timer is similarly connected to identical three electrode switches 160, for each of theaccelerators 95 or 95', The timermay be set to complete an energizing or firing .cycle to the respective fast action switches 160 for each accelerator which cycles are spaced apart by any desired time interval. Oncethe intermediate electrode 1 63 is energized with a firing potential, the entire gap between electrodes 161, 162 becomes ionized, and the power circuit is completed through teaser wire 136' substantially instantaneously. The firing of the next accelerator is initiated in like manner and, if so elected, in an extremelybrief and accurately timed interval after the firing of the previous accelerator.
If it is desired to accelerate a particular kind of particulate, one or more particles of the selected particulate is supported in the throat of venturi passage 99 by mounting the "same on Mylar film 142 clamped between barrel member 96 of the accelerator and.
When the burst diaphragm 106 fails it is forcibly ejected through outlet passage 102 into a debris retaining chamber 103 andremains captive there out of the stream ofhigh pressure gas-flowing from chamber 104 into v enturi passage 99 of the accelerator. In this manner the diaphragm debris is instantly castout of the stream of high pressure escaping gas and does not impede or interfere with the free flow and expansion of the gas through the accelerator.
Referring now to FIGS. 2 and 3, it will be understoo that the test object or material 150 being subjected to heat and erosion testing is suitably secured in the top of a cup-shaped mounting fitting 151 having a threaded shank 152 mating with threaded socket at the'upper end 26 of shaft 25. Supporting'within the cup-shaped fitting 151 is a strain gauge or other suitable transducer. 155 having a sensor 156 in intimate contact with the rear side of test object 150. Electrical leads 157 extend from transducer 155 to the exterior of test chamber 21, along with other electrical-lead wires, through a suitablefluid-tight bushing assembly 158 mounted in housing wall 21 (FlG.2-).
Referring now to FIGS. 811, there is illustrated a further exemplary embodiment of environmental simulator apparatus embodying the principles of thepresent invention wherein the same orv similar components are designated by the same numeral as in the first described embodimentbut distinguished therefrom by theaddition of a :prime. As will be recognizedfrom a comparison of FIGS. 1-7 with FIGS: 8 -11, the two apparatuses differinno major respect. The principal differences reside in the fact that a substantially larger number of, accelerators 95 are present and these'are arranged in a loop surrounding the main housing. As
there shown, the axes of the acceleratorsare inclined acutely to.a common planepassing through the-center of the test object. It will be understood thatthe angles of the accelerators with respect to this plane may vary at the discretion of the designer and as necessary in carrying out the objectives of a particular test. Although accelerators 95' are shown as similarly inclined to this plane, they may be inclined at various other angles relative to one another and there may be more than a single ring of accelerators carried by the opening through the wall of the apparatushousing. For example, it may be expedient for the purposes of a particular test to have two or more rings, or to locate the axes of the accelerators in a spiral encircling the te'st'chamber one or more times, with their discharge ends and axes converging on the test surface located at the upper end of the rotary shaft 25. By these expedients, it will be appreciated that the length'of a test run may be greatly increased over that possible with the first described embodiment.
It is also feasible to design the apparatus for rotation of the test object in a single direction and without need it for reversing the direction of rotation to return the test surface to a positionopposite the first'a'ccelerator. It will also be observed that barrier 43' and its operating solenoid 41 is shown in FIG. 8 as supportedfrom the main housing rather than from shaft, 25, as it is in FIG.
As is clearly shown in FIG. 8 heater 46' is supported by bracket means 45 attached to a removableclosure 34" sealed across an opening 33" in axial alignment with the shaft 25'. The axis'of stationary heater 46' is therefore in alignment with the center of test object the particulate forms definite craters on impact.
Referring to FIGS. l0 and, thereis represented typical impact craters 160, 161, eachof which usually includes a characteristic encircling rim. The depth of the crater and its diameter are a function of the velocity of the particle impacting on ring 47' and producing the, crater. The size of the particle can be accurately determined in advance of the test. It will be understood that. the size of ports 49' varies to suit the needs of the-pap ticular test beingmade and is usually so chosen that the majority of the particles emanating from a particular accelerator pass through the port. However, if the port is made sufficiently small, most of the particles will im-.
activation in sequence and as'determined by the opera-..
tion of the indexing motor 28 effective to close the electrical circuit to the accelerators in turn and advancing the test specimen or object into the path of the gas and particulate issuing therefrom.
OPERATION Let it be assumed that it is desired to conduct an oblative or erosion test on a particular material intended for use on the exterior of a spacecraft as the craft passes through a predetermined trajectory relative to the earth s atmosphere. A small plaque of material 150 chosen for the part is prepared and supported as indicated in FIG. 3 with its rear surface in contact with sensor 156 of transducer 155. The upper lip edge of the fitting 151 enclosing the transducer is so prepared as to support the exposed surface of the test object at an appropriate attitude, such as that indicated in FIG. 3.
If the trajectory is to pass through dust clouds, rain, snow, ice and micrometeorite showers, then the various accelerators 95 are properly prepared each with particulate of the type to be encountered by the test object during its trajectory. For example, the Mylar I diaphragm 142 of one accelerator is prepared with dust particulate. The corresponding diaphragm of another accelerator is prepared with water vapor; another with ice crystal particulate; another with micrometeorite particulate, etc. The pressure chamber 104 of each accelerator is also armed with a teaser 1'36, locked in its cocked position as shown in FIG. 6 by its associated armature 132 and the outlet end of each pressure chamber is equipped with a burst diaphragm 106.
The foregoing preparations having been completed with respect to each of the accelerators, each of the pressure chambers is charged with an appropriate quantity of gas via a charging conduit 152. While various gases may be employed, higher velocities are achieved using a very light gas, such as hydrogen or helium. The kind of gas and the pressure to which the chamber is charged has a direct bearing on the velocity attained by the gas as it discharges from the accelerator and on the velocity to which the particulate mounted on diaphragm 142 is accelerated. Accordingly, it is desirable that the charging duct 152 be connected with suitable gauge or pressure regulator means, not shown, to facilitate the gas charging operation.
' The next step to be performed is that of evacuating the interior of housing 21 to a high vacuum corresponding to that at the start of flight trajectory. Evacuation is accomplished using suitable evacuating equipment connected to the interior of housing 21 via conduit 156. The bank of capacitors 120 for each accelerator 95 is charged to a selected level desired for the associated accelerator following which the charging switch not shown is opened. The apparatus is now in readiness for the test run, it being understood that the optical pyrometers and the recording camera equipment indicated at 37 are properly positioned and trained on the test object 150 through window 36 and that the test object itself is slightly'misaligned with the first one of the row of accelerators 95 to be activated in succession. If the test object is operating in a raritied atmosphere as the first particulate is encountered, the test object is brought up to the appropriate initial temstabilized with heat shield 43 extended crosswise of the discharge end of the heater as is illustrated in FIGS. 2 and 3. Once the heater temperature has been stabilized to the selected temperature, solenoid 41 is activated to retract heat shield 43 whereupon the heater quickly heats the test object 150 to the proper temperature, simulating desired conditions as the first of the accelerators is activated.
The test run is initiated by starting motor 28 to rotate shaft 25 supporting the test object until the test object is aligned with the discharge end of the first of accelerators 95.
While not so shown, it will be understood that th test object and heater 46 need not be located opposite the focus of the axes of the series of accelerators as now shown in FIG. 2, but may be mounted on arms carried by shaft 25 and positioned to be indexed by this shaft successively into the path of the discharge from the accelerators 95. In fact, it may be desirable and is within the scope of this invention to make the supporting arm for the heater and the test object adjustable in length thereby to vary the proximity of the test object to the outlet end of the accelerators thereby to v ary the wind and skin friction loading on the test object. A solenoid operated step-by-step feed would suffice to. vary the radial length of the arm supporting the heater and the test object relative to the axis of shaft 25.
As the test object reaches this first index position, rotary switch 30 completes a circuit between contacts 32, 33 energizing the solenoid 128, thereby retracting armature 132 and allowing the pressure within chamber 104 to extend plunger 133 outwardly so that the upper end of teaser 136 completes a circuit for thehighly charged bank of capacitors 120. This creates a massive arc and releases the energy into the captive gas in chamber 104 thereby substantially instantly raising its temperature and pressure to the desired high value, rupturing diaphragm 106 and releasing this very high pressure gas into accelerator passage 99.
The debris of the diaphragm 106 is immediately rejected by being cast and held captive in debris chamber 103 whereas the pressurized gas flows into venturi 99, instantly destroying diaphragm 142 and accelerating the particulate thereon by drageffect to the desired velocity for the particular test condition being simulated. Usually, and if desired, the particulate is accelerated to hypersonic velocity but may be accelerated to any lower velocity prior to impacting on the test object. Only accelerated particulate aligned with port 49 passes through and impacts on the test object, all other particulate impinging on discriminator 47.
An observation is then made of the test object through window 36, and a photographic record is taken. Shortly thereafter motor 28 operates to index shaft 25 and test object into alignment with the axis of the next accelerator, stepping of the test object to its different indexed position preferably beinglcarried out in time-delayed sequence byany suitable programmed control for motor 28. As the. specimen rotates into alignment with the axis of the next accelerator, discriminator 47 and heater 46 are rotated therewith. Likewise, solenoid 41 controlling the operation of the heat barrier or shield 43 is also rotated since it is carried by and rotates with shaft 25. Rotary switch 30 will be understood as cooperating with brush carrying arm 31 to complete an energizing circuit for the successive tions change during the trajectory. Usually the trajectory progresses through atmosphere of varying density, a condition corresponding to changing temperature conditions on the surface of the test object. Such temperature changes irrespective of the direction of the change is readily achieved by regulating the operating condition of heater 46. This is accomplished in one of many ways including varying the applied voltage between electrodes 56 and 60 and/or the temperatures, types and quantities of gases introduced through supply; pipes 72, 77. An infinite degree of regulation is readily achieved by varying the pressure, quantities, preheated temperature and types of the gases introduced through these two pipes. Any substantial temperature change is preferably obtained while the heat barrier shield 43 is extended to lie between the heat and the test object. Once stableoperating conditions at a desired temperature are obtained and checked using an optical acute angle to a plane through the axes'of the several accelerators it will be understood that the test object may consist of a miniature representation of any object and that this may be disposed at any angle relative to the axis of the several accelerators by providing a suitably contoured supporting fitting 151 for the test object and for sensor 155. Likewise, it will be un' derstood that the heater 46 may be disposed at dif ferent angles by providing a suitable substitute bracket 44, 45. These various fittings and accessories may be varied widely and as found most suitable and convenient for conducting a particular type of test.
Although the foregoing description of the operation has been described with reference to the embodiment shown in ElGS. 1-7, it will be understood that the second illustrative embodiment operates essentially in the same manner except for obvious differences based on the described structural differences. Only shaft and the components attached to the shaft rotate. It will be understood that the electrical connections to the transducer shown in FIG. 3 may include slip rings, not
' shown, but mounted in well known manner on shaft pyrometer positioned opposite window 36 and trained on the adjacentsurface of the heat barrier, barrier 43 is retracted by energizing solenoid 41-v in the proper direction. Once the surface of the test object has been stabilized at the desired temperature and checked by the pyrometer, the next accelerator is activated provided the test object is in position therewith.
It will be understood that solenoid 41 for the heat barrier may be of-the double acting type which extends the barrier in one direction during one energizing cycle and retracts it during the next energizing cycle. Alternatively, the solenoid maybe of the single acting type which holds the barrier in one direction when energized and relies'upon spring action to restore the barrier to its alternate position when the solenoid is de-energized.
As is evident from FIGS. 3 and 4, conduits 71, 77 are there shown as discharging tangentially into the flow passage, but on the opposite sides thereof. This disposition of the gas inlets. promotes intimate mixing and more efficient heating. Any gas introduced through conduit .72 augments and increases the swirling initiated and produced by the rotating flux field of coil 74. It will be understood that thiscoil is protected from overheating by a suitable layer of heat insulating material 74' interposed between the coil and the main body of the heater. i
It is also pointed outthat thesensing device 155, 156 is connected-to appropriate dynamic recording equipment through suitable amplifiers to provide'a recordof the impact of particulate upon the test object during operation of each ofthe accelerators. Desirably, the same recorder making a record of transducer 155 also contains a runningrecordof the stabilized temperatures of heater 46 after these have been established for a particular index position.
Although the test object 150 as represented in the present drawing comprises a thin disc supported .at an While the particular apparatus and method for simulating spacecraft erosion herein shown and disclosed in detail is fully capable of attaining the objects and providing the advantages herein stated, it is to be -understood that it is merely illustrative of the presently object within said chamber, preheating and maintain ing the exterior surface of said test object heated to a temperature corresponding to that generated by travel of the object at a selected velocity under the said desired atmospheric environment condition, thereafter accelerating successive groups of preselected quantities, kinds and sizes of particulate matter to a relative velocity corresponding generally to said selected velocity of travel, and impacting said successive groups of accelerated particulate matter on the preheated test object in programmedsequence.

Out in the yard, melons are ripe and ready for eating!
The Schoon's Hardshell melon that we ate earlier this week was lightly sweet and nicely cantaloupy. So far, none of this variety have split. Since we haven't had any big rainstorms up from the Gulf yet, I'm not sure that this summer has been a fair test of the variety's sturdiness in my yard, but I am happy with it so far!
The Sakata's Sweet melons are not having a good year in my yard. For unknown reasons, the plants were much slower in getting established than the other melons, and the vines have not been especially fruitful. The biggest melon from this variety in my yard is small, just a bit bigger than a softball, and I noticed yesterday that it had split open around the stem even though it wasn't all that close to being ripe. I picked it to bring into the house anyway. The other melons on these vines are even smaller —baseball size— so it is unlikely that I will grow this variety again, even if they turn out to be delicious. I really want more standard-size melons.
We've also eaten a Sugar Nut melon from the yard. This variety is greenish on the inside and so sweet it is like a little sugar-bomb in your mouth. Sadly, I found a split Sugar Nut melon in my garden early yesterday morning, but this variety had never split in my garden until now.
The great irony is that, this year, I recommended that we try growing Sugar Nut at the Plant-a-Row-for-the-Hungry (PAR) garden where I am a volunteer, because the other varieties that we had grown split so easily. We just have never been able to take many small melons to the donation center where we drop off our veggies, because so many little melons exploded before they were completely ripe. I had hoped that the Sugar Nuts would stay intact, like they had in my yard for the previous several years.
However, at the PAR garden yesterday morning, we found two Sugar Nut melons that had split. Of course, one of the Athenas had also split, and more dramatically than the Sugar Nuts, but I am a bit disappointed. The good news is that we were able to take 17.5 pounds of good, sweet, unexploded melons to the donation center in Marietta.

WASHINGTON, April 11, 2016 /PRNewswire-USNewswire/ -- The National League of Cities (NLC), National Governors Association (NGA), National Conference of State Legislatures (NCSL), U.S. Conference of Mayors (USCM), and the National Association of State Aviation Officials (NASAO) today released the following statement urging the members to adopt a bipartisan amendment to the Federal Aviation Administration (FAA) Reauthorization Act of 2016.
Amendment No. 3558 to H.R. 636 would preserve the balance of federal, state and local regulatory authority to ensure the continued safe integration of unmanned aerial systems (UAS). The amendment was submitted by Senator Dianne Feinstein (D-Calif.) and co-sponsored by Senators Thom Tillis (R-N.C.) and Richard Blumenthal (D-Conn).
"Section 2152 of The Federal Aviation Administration Reauthorization Act of 2016 broadly and unjustifiably preempts state and local authority. It also goes well beyond the basic assertion of the FAA's authority to regulate the safety of the national airspace system.
"Further, it infringes on traditional state and local powers to protect the basic rights of citizens and address gaps in federal regulations related to UAS. We offer our full support for amendment No. 3558 from Sen. Dianne Feinstein to preserve the balance of federal, state and local regulatory authority and ensure the continued safe integration of UAS."
