THE PROPOSED WORK INVOLVES APPLICATION OF SUPPORTED MOLTEN SALT CATALYSIS TO THE CATALYTIC ENDOTHERMIC DEHYDROGENATION OF HIGH ENERGY-DENSITY AVIATION FUELS. THE CATALYSTS OF INTEREST ARE HETEROGENEOUSLY DISPERSED PLATINUM AND NICKEL, TO BE USED ALONE OR IN BIMETALLIC CLUSTERS. THE MOLTEN SALTS TO BE USED INCLUDE BINARY AND TERNARY EUTECTICS INVOLVING ALKALI METAL CHLORIDES AND HYDROXIDES. THE SUP ...

CURRENT FRAME BUFFER TECHNOLOGY IS NOT OPTIMIZED FOR USE WITH GENERAL PURPOSE PROCESSORS. THIS PROPOSAL IS FOR A PROGRAM TO DEVELOP A BREADBOARD FRAME BUFFER WHICH IS EFFICIENTLY ACCESSED BY SUCH PROCESSORS. THE FRAME BUFFER IS BASED ON THE VME BUS AND IS SCALABLE TO LARGE AMOUNTS OF IMAGE MEMORY AND VERY FAST IMAGE ACQUISITION RATES. ALL IMAGE DATA IS RANDOMLY ACCESSIBLE AT HIGH SPEED. ANTICIPATE ...

THIS NATION HAS MORE THAN 11 MILLION MANHOLES WHICH NOW NEED, OR SOON WILL NEED, TO BE REHABILITATED. CURRENT TECHNIQUES ARE EITHER TOO COSTLY OR DO NOT LAST. THIS RESEARCH SPEAKS TO THIS PROBLEM THROUGH DEVELOPMENT OF AN INNOVATIVE TECHNIQUE OF RESTORING MANY OF THESE STRUCTURES AT LESS THAN HALF THE COST OF THE RELIABLE METHODS AVAILABLE TODAY. THE CONCEPT USES A NEWLY DEVELOPED APPLICATOR WH ...

This Phase I research is intended to evaluate the feasibility of manufacturing low-cost, acid-resistant sanitary sewer pipe from sulfur concrete. Sulfur is an abundant mineral recovered from coking, natural gas processing, and petroleum refining. Secondary recovery of sulfur, resulting from environmental regulation, produces more material than is needed by U.S. industry. The U.S. Bureau of Mines ...

A high repetition rate mid infrared laser (3-5 microns) capable of providing multispectral output covering all bands used by infrared missile would make a solid state laser based IRCM system a potentially attractive replacement for black body infrared jammers. We propose a novel laser concept that can provide the desired spectral output at repetition rates exceeding the current state-of-the-art. W ...

IN AN EFFORT TO REACH HIGHER POWERS, LASER RESEARCHERS HAVE DEVELOPED LARGER AND INCREASINGLY COMPLEX DEVICES. AN ALTERNATE SCALING APPROACH IS TO COMBINE THE OUTPUT POWER OF MANY SIMPLE LOW-POWER LASERS IN AN ARRAY. MICROLASERS ARE THE PERFECT ARRAY ELEMENTS BECAUSE THEY ARE MASS-PRODUCIBLE AND HAVE POLARIZED, SINGLE-FREQUENCY, DIFFRACTION-LIMITED OUTPUTS. RESEARCHERS HAVE DEVELOPED A UNIQUE M ...

Presently there are no broadly tenable, narrow linewidth souces that operate throughout the mid-infrared (mid-IR) region of the spectrum, from 1 to 5 microns. Traditional sources have very low spectral brightness (low power per unit spectral bandwidth). This proposal describes a novel approach to produce a source with very high spectral brightness, tunable over the range of 1.1 to 4.3 microns. ...

The high cost of near-to-mid infrared laser sources is problematic for many military applications, such as seekers where sources are short lived. Order-of-magnitude cost reductions are needed for 10-20 watt, 1-micron lasers. The proposed approach to reducing costs involves using novel manufacturing processes to greatly reduce parts count and assembly time, thus reducing cost. When applied to a ...
