40169 W. Peter Trower Applications such as medical tomography, x-ray defectometry, and metallurgical processing require high resolution spectrometric detectors. At present, the desired resolution can only be achieved using germanium crystals cooled to cryogenic temperatures, conditions which severely limit applicability. This project will develop x-ray and gamma-ray detectors that operate at r ...

THE CONCEPT FOR A BULK OPTICALLY-CONTROLLED SEMICONDUCTOR SWITCH (BOSS), WHERE TWO DIFFERENT WAVELENGTH LASERS ARE USED TO GENERATE AND QUENCH PHOTOCONDUCTIVITY WAS RECENTLY INTRODUCED BY SCHOENBACH AND LAKDAWALA AT OLD DOMINION UNIVERSITY (ODU). INSTEAD OF SUSTAINING PHOTOCONDUCTANCE BYLASER LIGHT, AS IN CONVENTIONAL PHOTOCONDUCTIVE SWITCHES, ONE LASER IS USED TO DRIVE THE SWITCH INTO A CONDUCTIV ...

41242 TPL, Inc. A number of industrial processes generate wastewater with heavy metal contamination. Existing cleanup processes have difficulties in achieving low metal contamination levels, especially in the presence of competing nontoxic ions, high ionic strengths, and particulate matter; costs of cleanup can be prohibitively high. An effective and economical process to remove heavy metal ions ...

40900 November 18, 1996 JP Accelerator Works, Inc. Linear collider accelerator systems, proposed to extend the frontiers of high energy physics research, require thousands of megawatts of peak rf power at microwave frequencies. Existing rf power devices such as klystrons are limited in rf peak power to levels that would require thousands of devices to po ...

40879 November 13, 1996 Karta Technology, Inc. In almost all glass-manufacturing processes, production yield depends critically on the viscosity of the melt. Because the glass viscosity is a function of temperature, most active control systems monitor the temperature of the molten glass. However, temperature readings are not reliable for measuring viscos ...

40394 November 18, 1996 Lynntech, Inc. Due to their high power density for both stationary or mobile applications, fuel cells employing solid polymer electrolytes have promising applications ranging from portable power sources to electric vehicles to commercial buildings. In a fuel cell, a solid polymer electrolyte should function as an acid electrolyte, ...
