Abstract: High density heatsinks for microcircuit packages are formed by first mold-pressing a composite powder of free-flowing spray-dried particles of an inexpensive high thermal conductivity material having a high coefficient of thermal expansion (CTE) such as copper and at least one other low CTE material such as tungsten, the proportions of which are adjusted to match the CTE of the microcircuit material. The pressed compacts are sintered in order to achieve an homogeneous distribution of the melting copper throughout the structure. A multilevel embodiment of the heatsink comprises two bonded layers of metals or composites having their coefficients of thermal expansion adjusted to match those of the semiconductor material and of any supporting structures respectively, wherein the second layer in contact with the supporting structure has a high CTE and the other has a lower CTE.

Abstract: In a banner display device where a plurality of banners are mounted end-to-end upon a carrier web to form a scroll which is wound on a pair of parallel and spaced-apart rollers, means carried on the scroll for stretching or decompressing a medial section of a displayed banner sufficiently to eliminate wrinkles and small distortions. One embodiment uses means for propelling the medial section away from the web comprising resiliently flexible banner end sections or resiliently flexible strips framing the banner which, when partially wound over the rollers, resiliently assume a more planar tangential position in relation to the rollers, thereby allowing the medial section to jut anteriorly away from the carrier.An embodiment further comprises two independent lateral support members capable of being mounted within enclosures having widely different widths. Components such as motors, transmissions, roller mounting spindles, control sensors and circuitry are mounted directly on the support members.

Abstract: A device for releasably fastening a cover slab to the opening of a crypt or niche extending back from a vertical support wall. Each device is positioned at a common point of adjacency of a plurality of slabs. Each device has a rotatively mounted locking plate for engaging slots in the sides of each of the slabs. The plate has a cutaway sized and dimensioned to allow for the passage of one of the slabs through the cutaway when the cutaway is rotated into proper alignment. Keyed tool means for turning the plate indicated the positioning of the cutaway.

Abstract: A non-lethal weapon for disabling an engine such as that of a fleeing car by means of a high voltage discharge that perturbs or destroys the electrical circuits. The transmission of the disabling voltage to the distant target is via two channels of electrically conductive air. The conductive channels are created by multi-photon and collisional ionization within the paths of two beams of coherent (laser) or collimated incoherent ultraviolet radiation directed to the target. A single beam may be used when the high voltage source and the target are grounded. The high-voltage current flows from electrodes at the origin of the beams along the channels of free electrons within them.

Abstract: A drilling template for carving into the lateral edge or the jamb of a door, a cavity shaped and dimensioned to receive either a flanged lock or its strikeplate has a series of drill bit bores at regular spaced-apart intervals along a central line, a pair of lateral legs with sharp ends, and mounting holes corresponding to those of the lock or strikeplate. The template is designed to be hammered into the door edge or jamb until the sharp edge-ended edges define the outline of the lock flange or of the strikeplate as well as the amount of wood to be removed to form the mortise necessary to nest those elements. The template can be screwed in place through mounting holes that correspond to those of the lock or strikeplate. A drill is used to rout the cavity through the drill bit bores. Guides in either side of the bores prevent lateral movement of the bit, but allow slight longitudinal swing to remove material that may remain between holes.

Abstract: A hot water distribution system incorporating a pump positioned close to, and between each set of hot and cold water taps to which periodically move the cooled-down water content of the hot water distribution line through the cold water distribution line back to the hot water tank until the total content of the hot water line has a predetermined temperature. The pump is provided with a valve responsive to pump-generated pressure to prevent backflow when the pump is not in use and the pressure in the cold water distribution line is lower than the pressure in the hot water distribution line, such as when water is drawn through a cold water tap.

Abstract: A compact, rugged, long-lasting, battery-powered light fixture suitable for use as an emergency signal, marker, or flashlight has a lighting element made from a phosphorous-based luminescent film section curled into a cylindrical shape and packaged within a transparent tubular enclosure. The AC power supply and batteries are held in the center of the enclosure inside the lighting element.

Abstract: In the manufacture of molded or laminated articles from composite materials such as fiber-reinforced and carbon or metal-loaded resins, the vacuum plastic bag or other air-tight barrier commonly used during the pressing, heating and curing phases is eliminated. Instead the various process cycles are conducted in one or more fluid-tight pressurizable chamber under various types of atmospheres to eliminate air pockets, vaporize and evacuate moisture and residual solvents, and suppress surface bubbling and frothing of pressed out fluids.

Abstract: Atomized metal particles distributed within a resin matrix form a composite that can be selectively heated by exposure to microwave radiations. The composites can also be formed into non-electrically conductive but thermally conductive dielectric and magnetic structures by appropriate selection of metal particles and matrix materials.

Abstract: A portable, light-weight, electrically powered device that derives at least part of its power from manual mechanical input means having a rotatively mounted battery which provides electrical power but also acts as an mechanical inertial storage mechanism. The kinetic energy of the moving battery is capable of being utilized via a generator to energize the device's electrically powered element. In one embodiment, a compact high-output generator is disclosed for providing increased current over a given time period for recharging the battery. In another embodiment a rotatively mounted canister is provided for mounting one or more batteries or other variable mass materials if generator power is used exclusively. Manual input occurs via enclosed gear-based hand levers.

Abstract: Heatsinks for microcircuit packages are formed by first mold-pressing a composite powder of free-flowing spray-dried particles of copper and at least one other denser material such as tungsten and/or molybdenum breakably agglutinated in nodules grouping sub-nodules of surface alloyed pairs of particles of each metal, the proportions of which are adjusted to match the thermal expansion characteristics of the microcircuit material. The pressed compacts are then heated in a sintering furnace at 1090.degree. C. to 1150.degree. C. in order to effect an homogeneous distribution of the melting copper throughout the structure. The process results in a readily usable component having good thermal conductivity and matched thermal expansion that requires no further machining.

Abstract: A portable musculature exerciser designed to be mounted against a door provides a pair of parallel bars jutting out from the face of the door as well as a horizontal chin-bar for use in a variety of exercises. The back of the door provides a dorsal support in the performance of some of those exercises. The device comprises a generally U-shaped grab-bar suspended by a triple-strap yoke to a ribbon-like tail. The tail has a series of protrusions spaced apart along its length. When the tail is swung over the top of a door and the door is closed against its frame, one of the protrusions caught between the top edge of the door and its lintel prevents the tail from slipping out. The grab-bar can be knocked down into three elongated parts that can be conveniently stored in a briefcase or similar enclosure.
