Electromechanical and fiber-optic interface devices that transmit either electrical power or electronic data between a stationary element and a rotary  element, allowing unencumbered 360-degree rotation. Applications are in aircraft, satellites and space vehicles, and in many types of industrial equipment  including medical machinery. Slip Rings: 2003 TERMS: Moog provides hardware for two types of plastic processing machinery. The first  type is injection molding in which hot molten plastic is injected into cold molds using  a hydraulic piston. After the part cools and solidifies, the mold is opened and the part  is ejected. The second type is blow molding which begins by using heat to soften a  plastic so that it can be extruded (pushed out) into a hollow tube called a parison.  While the tube is still soft, a mold closes around the tube, pinching the top and  bottom of the tube. Then, a pin is introduced and air is forced through the pin  blowing the tube into the shape of the mold cavity. Gravity Probe B is a satellite being built by Stanford  University and Lockheed Martin Missiles and Space to test two unverified predictions of Albert EinsteinGLYPH<213>s general theory  of relativity. The experiment will check minute changes in the direction of spin of four gyroscopes orbiting at a 400 mile  altitude directly over the poles of the Earth. The gyros will measure how space and time are warped by the presence  of the Earth and how the EarthGLYPH<213>s rotation drags space-time around with it. MoogGLYPH<213>s aircraft actuators are designed to provide flawless performance over time  measured in decades. Periodically, the actuators need overhauling to bring them back to their original specifications. MoogGLYPH<213>s overhauls and repairs guarantee the use of original factory parts and assembly and testing by expert technicians. Aircraft Aftermarket: Gravity Probe B: 23 Plastics Market:
