Abstract: A key rack with a unique stacking system is provided. The key rack has grooves and/or curves provided thereon such that the grooves and or curves of one key rack fit into the grooves and/or curves provided on another rack thereby allowing one rack to combine with a second rack to form a larger key rack system. The key rack has a tier system of hooks that allow for one tier of hooks to be horizontally and vertically offset from a second tier of hooks.
Abstract: The invention is a novel body armor that comprises a metallic layer having a surface contoured for close fitting to the wearer, the layer bounded by an outer perimeter, a second layer of organic material located adjacent the metallic layer, the layer of organic material having the same surface contour as the metallic layer, an inter-layer of releasably engageable fasteners inserted between the metallic layer and the organic material layer to form a multi-layer laminate, and a layer of semi-flexible plastic surrounding and in contact with the outer surfaces of the metallic layer, to form an armor unit cover.
Abstract: A device for correcting residual mis-convergence errors in a color cathode ray tube, the tube including a narrow-necked section, located at the rear thereof, in which electron guns mounted therein generate forwardly-directed red, blue and green electronic beams, an outwardly-opening center skirt section, extending forward from the narrow-necked section, and terminating in a wide perimeter surrounding a relatively flat, pixel-coated, viewing screen section that is arranged generally orthogonal to the axis of the narrow-necked section and upon which the electronic beams are directed to strike the pixels to produce color and images for viewing from the front of the tube, and further having at least one pair of electromagnetic coils mounted outside the tube, for initial focusing of the electron beams during their travel from the guns to the screen, the device including a separator made of a plastic, including a high density of magnetizable particles therein, the separator arranged for placement about the outside
Abstract: A compact, lightweight, steerable, high-power, microwave weapon including a self-powered, steerable vehicle having at least one exterior antenna support surface, a self-powered, microwave radiation source mounted in the vehicle and including a waveguide to connect the power source to the exterior surface, a feed horn, extending from the waveguide means, including a window transparent to microwave energy for receiving and radiating a pulsed, high-energy microwave radiation beam, a transreflector fixedly mounted on the exterior surface arranged spaced-apart and above the feed horn and having a concave surface facing the feed horn window and formed of a plurality of electrical conductors held in parallel order in a frame, and a twistreflector pivotally mounted opposite and spaced-apart from the concave surface of the transreflector and adapted to receive microwave energy reflected to it from the concave surface of the transreflector and to rotate the polarization by 90° and reflect the microwave energy back

Abstract: A bait-holding lure made of a front element, a rear element spaced-apart from the front element, a cage, defined by spaced-apart front open end and rear open end, the cage arranged between the front element and the rear element, the cage having a hollow interior forming a cavity for retaining a quantity of bait therein, the cage further defined by a perforated, contoured outer wall throughwhich water may flow to carry the taste and scent of the bait into the surrounding water, and a spindle containing a straight portion arranged to pass axially through the cage, a first aperture formed in the front element, and a second aperture formed in the rear elements to hold them in axial alignment, the spindle further including a return bend forming one end of a bent segment spaced-apart from the spindle, the segment containing a bend and a hamulus for connection to the spindle under bias pressure from the return bend to hold the front element, the cage, and the rear element in close assembled formation on the spindle.
Abstract: A launchable, multi-sensory distraction grenade including a base, three outer grenade walls arranged together on the base to pivotally move from a first position, to a second position, extending outward laterally from the base in different directions, to form lateral legs to support the base after it lands on a surface, a plurality of spring fingers retaining the walls in contact with the base, at least two distraction devices mounted in the grenade for initiating an extended period of personnel distraction in the area of the grenade with its walls in their second position, a distraction device ignitor and safety trigger at least a portion of which is external the casing for controlling the ignition means.

Abstract: A method and apparatus for rejecting signals exhibiting pulse pile-up and devices incorporating the method and/or apparatus. A pulse sensor senses pulses and an analog-to-digital converter digitizes the sensed pulses into discrete ADC values over a plurality of time slices. The digitized pulses are stored in a FIFO memory for processing by a classification processor. The processor qualifies the pulse and marks its first time slice. The processor includes accumulators that calculate parameters from various regions of the pulse. The calculated parameters are compared to criteria from identical regions of known, non-piled pulses. Pulses whose calculated parameters meet the criteria are accepted and stored in one memory location, and pulses whose calculated parameter do not meet the criteria are rejected and stored in another memory location.
Abstract: A jamb system for framing panels, in which at least one of the panels is arranged to slide by another panel along a set of tracks, including an elongated top jamb including one elongated top guide member for each panel, each member including an elongated rail for guiding a panel along its travel within the jamb, and a key spacer member, the top guide members and the key members each adapted to interlock through their respective walls to form a rectilinear assembly, including slanted wall portions arranged to mate in adjacent juxtaposition with each other to accept a threaded fastener therethrough and an elongated side jamb for each panel, and an elongated key spacer member for insertion between each pair of the elongated side members allowing the panels to move along the rails within the jamb, past each other, adapted to interlock through their respective walls, the side members and the key members including slanted wall portions arranged to mate and accept a threaded fastener there through to hold the side j
Abstract: A device for increasing the sensitivity of a testing instrument in determining the presence of an electronic component, such as a miniature ceramic chip capacitor, at the test station before beginning the test procedure, including a signal booster having an input and an output in operable arrangement for boosting an incoming alternating signal from the testing device by a multiple greater than one, connecting the input of the signal booster between the signal output of the testing device and the station for positioning the component for measuring, and connecting the output of the signal booster between an independent direct current power supply and the test station to boost the signal of the presence testing program by a multiple that brings the measurable signal of the component within the range of sensitivity of the testing instrument.
Abstract: A buoyancy compensator vest, for providing buoyancy at various underwater depths, having a rigid back board, for supporting an air tank vertically on the rear surface of the board at the back of the diver, surrounded in part by a bladder, for inflating and deflating, and a vest back panel including a pair of spaced-apart over-the-shoulder straps projecting from the top panel edge for joining with a pair of side portions extending about the chest of the diver, and a waist belt passing from behind the compensator vest about the panel side portions and the user's waist to complete the vest, the improvement of a pouch, defined by front and rear surfaces and including an openable panel to expose the interior thereof, the pouch interposed the back board and the scuba diver's back and containing a cushion for placement against the back of the diver, to cushion the back board and tank against the diver's spine, the pouch having openings formed therein to allow filling and draining of water during under
