Abstract: A high rate rechargeable silver-zinc pile type battery including a plurality of bipolar electrodes which are assembled into a full scale multi-cell pile. Each of bipolar electrodes includes a positive side having a porous silver matrix attached to silver foil and a negative side having a porous zinc structure vapor deposited on silver foil. A separator including three different components in layers is disposed between the positive and negative sides of the bipolar electrode. An epoxy adhesive is used to position and retain a seal in its proper location to electrically isolate the individual electrodes and form a cavity for retention of the electrolyte. Intercell connectors of etched silver foil serve as the cell case and active material substrate as well as the series connection between individual cells for electrical continuity.

Abstract: A spring compressing tool including a plate having three spaced holes therein. A center hole is provided to allow access to the locking nut of the caster assembly and two other holes in the plate are in alignment with two already available holes in the caster flange. Two elongated threaded studs extend through the aligned holes in the plate and flange elements with nuts engaging the threaded portions above the plate and below the flange holding the spring compressed and the outer and inner cylinders in a fixed relative position while the locking nut of the caster is removed. Loosening of the nuts on the elongated studs allows the outer cylinder to move upward causing the pressure on the caster spring to be relived gradually until the spring is fully expanded and can be safely removed. The spring is replaced in the caster assembly by reversing the procedure outlined.

Abstract: An air dropped penetrator or projectile for a gun, (herein referred to as the munition), adapted for use in fracturing and penetrating a hard concrete target or a similar highly resistant target. In the most basic and generic form, the munition includes: a forward kinetic energy penetrator section, an aft follow-through ungula-shaped penetrator section, and a frangible intermediate section in the form of a tube which releasably interconnects the forward section and the aft section, thereby forming an integrated munition. Upon impact of the munition on the target, the frangible intermediate section breaks, thereby separating from the forward and aft sections, and also separating the forward and aft sections. The forward section fractures the concrete target and penetrates it; and, the aft section follows-through the fractured and penetrated target.

Abstract: An outrigger arm assembly to prevent a would-be intruder from successfully climbing over a fence. The outrigger arm assembly is mounted on top of the fence. Each hollow fence post is interconnected to a hollow outrigger arm by a replaceable collar which breaks when a load in the range of 20 to 30 pounds is applied to the outrigger arm, resulting in the downward movement of the outrigger arm, and the fall of the climber. The assembly also includes a movement sensor, within the hollow arm, which is activated and provides an alarm signal, when the outrigger arm is moved more than a predetermined number of degrees, such as the downward movement of the outrigger arm. The assembly further includes a coiled spring, positioned within the hollow fence post and extending into the hollow outrigger arm, by which the arm is automatically returned to its original defensive position, after the load is removed.

Abstract: An air-cooled, variable-throat, convergent-divergent nozzle for a turbojet engine. Active cooling constituent structures of the nozzle include: passages, for flow of cooling air, integral to, and within, convergent and divergent flaps and seal members; finned sections in nozzle components which are provided air from the passages; air exit slots on the convergent flaps; a hinged connection at each convergent flap-to-divergent flap (and divergent seal member) interconnection; staggered air outlet openings in each divergent flap; and, a tubular air feed system to provide cooling air from each divergent flap to an adjacent cooperating divergent seal member. Passive cooling is accomplished: by seal members overlapping adjacent side edges of convergent and divergent flaps, preventing leaking of cooling air and hot gas through the side edges; and, by a sealing hinged connection at each convergent flap-to-divergent flap (and divergent seal member) interconnection.

Abstract: An apparatus for automatically decoupling two bodies that are coupled and are under a tension load. Unlike the prior art, the decoupling is actuated and accomplished entirely mechanically, and without the use of any explosives; and, the apparatus is reusable.

Abstract: A system which automatically: removes rounds of ammunition from their presently-existing standardized ammunition shipping/storage container; transfers the removed rounds and loads them into an aircraft system for use; separates the returning downloaded spent cases from the returning unfired rounds; and, repackages the unfired rounds back into shipping/storage containers. The system includes: an ammunition trailer on which are carried the filled shipping/storage containers of unfired rounds of ammunition; a loader assembly which is the major component of the system and onto which the containers of ammunition are loaded; flexible chuting that houses ammunition round-conveyor elements and that is attached at one and to the loader assembly; and, a loader/aircraft interface unit which is attached at one end to the other end of the flexible chuting, and is attached at the other end to the aircraft and the aircraft gun system for use of the rounds of ammunition.

Abstract: A relatively small bidirectional polymeric piston seal especially useful for cryogenic refrigerators having an E-shaped metallic spring retainer and two wound spring seal expanders positioned between two L-shaped polymeric seals. The L-shaped design permits the use of conventional tooling with high strength abrasive polymeric compounds while maintaining tighter tolerances during manufacture thereby keeping frictional resistance at a uniform level to produce longer wear life at the required high pressure forces in two directions.

Abstract: A clamping device for securing a workpiece such as an electronic package to a support such as a heat sink. A curved slot is machined around a central opening in the body of a configurated flat metal clamp having an extending lip which contacts the edge of the workpiece. The central opening in the clamp body receives a hold down screw member which threadably engages the support. When the hold down screw is fully tightened against the support with the extending lip over the workpiece, the known clamping force predetermined by the thickness and configuration of the clamp body is applied. The need for a torque wrench and specific fastener torque values to prevent possible distortion of the surface of the heat sink is eliminated.

Abstract: A manually operated tool for relieving material on a 360.degree. staked aircraft bearing by performing an accurate concentric cut at a controlled feed rate with a nominal cutting force. Three equally spaced cutting blades stabilize the cutter assembly while an integral timing and blade calibration component also serves as a retention collar. The staked grooves of the bearing race provide for concentric positioning of the cutter instead of the bore of the bearing thereby preventing possible damages.

Abstract: A two stage remotely actuated structural latch especially suitable for supporting an aircraft canopy during flight as well as on the ground. One single part of the latch carries all of the load and the latch can be locked or unlocked from a remote location by use of a rod, cable or tube to acruate only non-structurally loaded pins and links which have high mechanical advantage in the first stage unlocking movement. This arrangement permits emergency canopy release during flight by the application of average human leverage and provides maximum pull up capability at the time of maximum mechanical advantage. A self-aligning and floating hook pin concept eliminates the need for hook and mating pin alignment.

Abstract: An adjustable fluid flow and spray control for use in conjunction with a manifold. The rate of flow of a fluid, and the rate of spraying of the fluid, are controlled by moving a pintle, instead of further deforming the manifold, as is conventionally done.

Abstract: An improved oil deaerator having an entrance tube with holes to allow much of the air to escape prior to entering the deaerator entry tube which is inclined and flattened causing the air/oil mixture to flow against the inside of the cylinder with the oil going to the outside and out the bottom louvers and the air escaping through a spout at the top. The unique design of the bottom with slotted or louvered oil exit openings and double cylinder arrangement reduces the possibility of the formation of a vortex.

Abstract: An ejector rack that is attachable to an aircraft and is for supporting and selectively releasing and/or ejecting a store that is carried internal of the aircraft, i.e., in a bomb bay. The store can be released from the ejector rack, and from the aircraft, in either of two ways, namely: by pushing on a manually operated release handle; or, by forced ejection, the only way used during flight of the aircraft. Forced ejection is achieved by sending an electrical impulse to either or both of two cartridges in the breech of the ejector rack, igniting the cartridge(s). Gas is generated thereby; and, the resultant pressure that is built up in a gas system in the rack provides force that acts upon an unlocking piston, causing the piston to move out of its "locked" position. In turn, the moving piston provides a force on a slide, rotating a latch that allows the main linkage bellcrank to rotate and thus to open two hooks which are holding the store, thereby releasing the suspended store.

Abstract: An intermittent motion device which converts input continuous motion into precisely timed output interrupted intermittent motion. In a generic preferred embodiment the device comprises a primary driver and a secondary driver that are attached to an input shaft, and a two-sided indexing driven wheel attached to an output shaft. The primary driver engages one of four drive slots on the primary side of the driven wheel, and rotates the driven wheel 72.degree. each time the input shaft makes one revolution. The secondary driver engages the one slot on the secondary side of the driven wheel, and rotates the driven wheel 72.degree. every fourth revolution of the input shaft. The indexing driven wheel is locked in a stationary dwell position between indexes by locking rollers on the driven wheel that engage in locking grooves in the primary and secondary driver wheels.

Abstract: An assembly adapted to perform sequentially the following: to extract horizontally rounds of ammunition from containers that are being indexed downwardly by a vertical conveyor; to position the extracted rounds of ammunition over a horizontal conveyor; and, to insert these rounds vertically downward into individual round-carrier elements of the horizontal conveyor. The preferred embodiment of the extraction assembly includes nine identical ammunition round extractor-release mechanisms (i.e., extractors), an extractor bar in which the nine extractors are mounted side-by-side, an extractor bar drive mechanism operatively connected to the extractor bar, an extractor roller element, and a horizontal extractor table with a drop-off section.

Abstract: A 30 inch ejector rack, for use with an aircraft, to support and release and/or forcibly eject a nuclear store (or a large conventional store) from the aircraft, with both the ejector rack and the store carried internal of the aircraft. Unlike the prior art, this ejector rack structurally incorporates, among other novel fundamental features and/or improvements: mechanical "spools", rather than valves or orifices, to obtain pitch or tilt of the store during forced ejection; bypass grooves near the end (i.e., the bottom) of the piston stroke to provide snubber action, thus preventing damage to the store due to impact of the piston and the store during ejection; cartridge debris screens in the gas system of the ejection rack and, structural configuration which permits quick removal of piston components for rapid and easy cleaning, without necessitating the complete disassembly of the ejector rack, or even the removal of the rack from the aircraft to which it is attached.

Abstract: An optical identification and communication system wherein an interrogator sends out a broad illuminator beam outside the visible range. Some of this radiation is collected by the transponder optic and focused on a converting phosphor. The response light is recollimated by the transponder optic and transmitted directly back at the interrogator. The use of co-axial optics along with color filters and an electronic "shutter" in the interrogator enables the transmitted and received radiation to be separated.

Abstract: A variable area nozzle which utilizes high pressure duct nozzle air directly to actuate a variable area nozzle and thereby control the nozzle throat area. A servo controlled air valve directs the duct air pressure into a pressure cavity causing the nozzle to move toward the closed position while the nozzle entrance pressure acting on the converging flaps urges the nozzle to move toward the open position while the pressure cavity is exhausted to ambient through the air valve. Thus, the need for mechanical and/or hydraulic drives with the associated cooling requirements to produce variations of the nozzle configuration are effectively eliminated.

Abstract: A holograph high resolution contact printer for use in transferring high resolution information, which is in the form of a pattern on a transparency, from the transparency to the light-sensitive photoresist material front surface of a light-recording medium having a light insensitive substrate rear surface, in which the light-sensitive photoresist surface previously has been exposed to a preselected diffraction grating, but the recording medium has not been developed.
