Segmented Lasing Tube for High Temperature Laser Assembly
U.S. Patent 5,497,392
March 5, 1996
A ceramic lasing tube having a plurality of cylindrical segments of the same inner and outer diameters nonrigidly joined together in axial alignment; insulation of uniform thickness surrounding the lasing tube; a ceramic casing, preferably of quartz, surrounding the insulation; and a fluid-cooled, metal jacket surrounding the ceramic casing.

John M. Halpin
Large Core Fiber Optic Cleaver
U.S. Patent 5,501,385
March 26, 1996
A device and method for cleaving optical fibers with core diameters greater than 400 micrometers to produce high-damage-threshold end surfaces. The device includes scribing means, a chuck assembly, and a fiber connector block. The fiber is scribed and then biased to apply cleaving tension.


Daniel M. Makowiecki
Nano-engineered Explosives
U.S. Patent 5,505,799
April 9, 1996
An explosive and fabrication method having a plurality of very thin, stacked, multilayer structures, each composed of reactive inorganic components separated by an organic component such as carbon. Upon detonation, the separator material reacts with the inorganic components to generate high temperatures and produce a working fluid or gas.

Organic Aerogel Microspheres and Fabrication Method Therefore
U.S. Patent 5,508,341
April 16, 1996
The formation of organic aerogel microspheres ranging from about 1 micrometer to about 3 millimeters in diameter by inverse emulsion polymerization with agitation. The aerogel microspheres can be pyrolyzed to produce doped or undoped carbon aerogel microspheres. The size and structure of the microspheres are determined by the processing procedures and the chemical formulation.

Flat Panel Ferroelectric Electron Emission Display System
U.S. Patent 5,508,590
April 16, 1996
A device that can produce a bright, raster-scanned or non-raster-scanned image from a flat panel by relying on electrons emitted from a ferroelectric emitter impinging on a phosphor. This device, unlike many flat panel technologies, does not require ambient light or auxiliary illumination for viewing the image.


Kurt H. Weiner
Method for Materials Deposition by Ablation Transfer Processing
U.S. Patent 5,508,065
April 16, 1996
A process in which a thin layer of semiconducting, insulating, or metallic material is transferred by ablation from a source substrate (which is coated uniformly with a material of a desired thickness) to a target substrate by means of a pulsed, high-intensity, patternable beam of energy.


Clinton M. Logan
Cooled Window for X-Rays or Charged Particles
U.S. Patent 5,509,046
April 16, 1996
A window that is capable of handling the thermal load from scattered x rays, electrons, or ions. The window offers good structural integrity and a very high capacity for removal of heat with minimum attenuation of the beam. The window has microchannels inside it through which coolant is pumped to cool the window.


Thomas E. McEwan
Time-of-Flight Radio Location System
U.S. Patent 5,510,800
April 23, 1996
A method and apparatus for detecting time-of-flight of electromagnetic pulses from a transmitter on an object to a receiver by sampling the pulses with controlled timing such that the time between transmission and sampling sweeps over a range of delays. An equivalent time sample signal is produced that can be processed to indicate object position.


Thomas E. McEwan
Homodyne Impulse Radar Hidden Object Locator
U.S. Patent 5,512,834
April 30, 1996
An electromagnetic detector and method in which a homodyne oscillator modulates pulses from a pulse generator and transmits them to a hidden object. Reflected pulses are detected by a receiver that includes a sample and hold circuit that is gated by the pulse generator to produce an averaged detected signal. The receiver includes an AC coupled amplifier and a rectifier connected to the homodyne oscillator to demodulate the detected signals.
