  • Patent number: 5833934
    Abstract: The reaction of alkali, alkali-earth metal hydride with water is utilized for the generation of hydrogen in a novel generator configuration. This overcomes the problems encountered in earlier hydride based generator configurations inasmuch as it overcomes the problem associated with the expansion of the hydride upon its conversion to hydroxide or oxide when reacting with water. This is accomplished by using a hydride cartridge of unique configuration. The combination of the corrugated cartridge structure and the wicking material dispersed throughout the cartridge facilitate the complete utilization of the hydride and water in a demand responsive mode. This is important in applications where intermediate hydrogen storage is impractical, as is the case in the use of these generators--e.g., for electric power generation in fuel cells in general and for Underwater Vehicles specifically because space restraints.

  • Patent number: 5833853
    Abstract: A method of manufacture of a radial-flow filter particularly suitable for use as an input filter in a subterranean fluid (oil, gas, water) well starts with a length L of multi-perforate pipe, which may be an integral part of the production tubing of the well. The pipe is mounted in an engine lathe with the perforated length L between the headstock and the tailstock of the lathe. With the pipe rotating, a strip of metal wool, preferably stainless steel wool, is wrapped around the pipe in repeated, overlapping helical layers each aligned at an acute angle X to the pipe axis, with adjacent layers angularly displaced by an angle 2X. The completed filter may have a tubular wire mesh around the pipe, between the pipe and the innermost layer of steel wool, and a multi-perforate sheath over the outermost layer of wool.

  • Patent number: 5829437
    Abstract: A method and system for detecting an incipient tumor in living tissue such as that of a human breast in accordance with differences in relative dielectric characteristics. A generator produces a non-ionizing electromagnetic input wave of preselected frequency, usually exceeding three gigahertz, and that input wave is used to irradiate the living tissue, being effectively focused into a minute, discrete volume within the tissue to develop a non-ionizing electromagnetic wave at that position. The illumination location is shifted over a portion of the living tissue in a predetermined scanning pattern. Backscatter signal returns from the living tissue are collected to develop a backscatter return signal wave.

  • Patent number: 5827595
    Abstract: A panel adaptable for use in automotive trim applications has a laminate of a support layer and an A-side layer made of vinyl or cloth. The support layer is made of a thermoformable material such as foam, felt or polypropylene. The laminate is thermoformed to impart the contour of a rigid substrate to which the panel will be attached. The support layer retains the desired contour without the use of other materials. The panel may have a shirred appearance imparted thereto by the inclusion of a plurality of gathers thermoformed into the support layer.

  • Patent number: 5815980
    Abstract: A device for the control of mosquito larvae includes a float and a self-contained electrical power source positioned on or within the float. There is a light source extending downwardly from the float and connected to the power source for activation thereof. A walled enclosure depends from the float, which enclosure will be filled with water when the float is placed upon the surface of a body of water. There is a generally 360.degree. circumferential opening generally intermediate the ends of the enclosure which permits the passage of mosquito larvae into the enclosure when attracted by the light source. The opening is located generally adjacent the light source and mosquito larvae attracted by light from the source will swim into the enclosure and then upwardly seeking air and will shortly thereafter expire due to the lack of air within the enclosure.

  • Patent number: 5818732
    Abstract: A process to determine the optimal initial settings for a series of timers in a timed-contribution batch process, based on the feed material flow rate and the composition of the material. The optimum initial timer arrangement is that which results in the maximum possible product output in the shortest possible batch time; this condition is realized when all of the minimum product requirements, as determined by the minimum timer settings, are satisfied at approximately the same time. The process first monitors the accumulation rates of the various constituents of the feed material for a discrete period of time, during which time a sensing device records the individual accumulation rates. Values representing the accumulation rates are normalized to the value of the greatest accumulation rate. A multiplier is applied to the resulting ratios to determine the optimal initial minimum timer settings. The maximum timer settings may be arithmetically or algebraically derived from the minimum timer settings.
