Abstract: A double-barreled tool for inserting and extracting electrical contacts includes an inner barrel and an outer barrel, the inner barrel being coaxial with the outer barrel and fully retractable therein. Each barrel has an elongated slot which are in alignment with one another. A means is provided for retracting the inner barrel into and extending the inner barrel from one end of the outer barrel. The contacts have lead wires extending therefrom. To extract and electrical contact from its installed position within an insulator body cavity, the contact lead wire is first slipped into the aligned slots of the inner and outer barrels. Then, the tool is guided along the wire and into the cavity, until the outer barrel impacts the dielectric within the cavity at a point at which the cavity narrows. At this juncture, the inner barrel is extended from the other barrel such that the end of the inner barrel approaches the electrical contact, thereby releasing the contact.

Abstract: Fixed parallel cargo rails are positioned on the cargo bed floor of an aircraft, spaced sufficiently to fit a pallet snugly therebetween. A plurality of collinear slots arranged along the length of the cargo bed floor are positioned just inboard of each rail. The slots are evenly spaced and oriented lengthwise with respect to the cargo bed floor. A dog extends above the cargo bed floor from each slot and is adapted to engage a notch in the cargo. While engaged, the dog is adapted to move along its slot, thereby moving the pallet lengthwise along the cargo bed floor. The pallet is passed bucket brigade style from one dog to the next.Another aspect of the invention is the employment of movable cargo rails on the cargo ramp. The rails are slidable widthwise across the ramp within mounting slots, thus permitting the spacing between the rails to vary. The result is that loading cargo onto the ramp and aligning it with the fixed cargo rails on the cargo bed floor is made much easier.

Abstract: A pitch stabilization system for an ejection seat includes a gyroscope rotor assembly having a pinion gear attached to two rotor wheels. The rotor assembly is mounted with a geometry to precess in response to change in the pitch rate of the seat. Precession of the gyro rotor rotates a vernier rocket with the resulting thrust applying a correcting moment to counter the adverse moment causing the ejection seat to pitch. When the seat is at rest in the cockpit of the aircraft, the rotor pinion gear teeth engage the teeth of a rack mounted stationarily to a fixed attach point on the aircraft. When an ejection force is applied to the seat, by a catapult or the like, the rotor wheel is rotated by virtue of the interengaging relationship between the rotor pinion gear teeth and the rack teeth so that by the time the ejection seat exits the cockpit the rotor disengages from the upper end of the rack, and is fully spun to operating revolution so that it can precess gyroscopically.

Abstract: This invention is an integrated anthropomorphic g-suit, with a breathing regulator and means for protecting the user of the suit from hostile environments. The suit has a flexible, distensible, impermeable inner liner that conforms to a user's body, and a flexible, impermeable, nondistensible outer liner that fits over the inner liner, to trap a thin layer of fluid between the inner and outer liners. The suit acts as a tank of fluid, so that the suit exerts a hydrostatic pressure on the user's body, preventing blood from draining from the user's head, when the user is subjected to acceleration. The breathing regulator is responsive to the pressure of the fluid in the suit, such that the pressure of the breathing gases being supplied to the user is approximately the same as the fluid pressure in the thoracic region of the suit. The regulator can vary the pressure of the breathing gas, automatically as a function of ambient pressure.

Abstract: A powered canopy breaker attached to an ejection seat, that fractures a canopy when the seat is ejected. The breaker has a piston that is operatively connected to an explosive cartridge. When the seat is ejected, the piston engages the canopy, pushing the piston a predetermined distance until the cartridge is detonated. The detonated cartridge ignites a detonating cord that fractures the canopy.

Abstract: This invention is an apparatus and method for applying sealant to a countersunk fastener hole. The apparatus comprises a sleeve, an adapter tube within the sleeve, a nozzle housing attached to the adapter tube, and a tip within the nozzle housing. A guide pin is attached to the adapter tube and follows an oblique slot in the sleeve. To operate, the sealant applicator is inserted into a countersunk fastener hole, engaging the tip with the countersink of the hole. The tip depresses into the nozzle housing, ejecting sealant onto the countersink. The adapter tube is pushed into the sleeve, moving the guide pin along the oblique slot in the sleeve. This guide pin movement rotates the adapter tube, nozzle housing and tip, causing the tip to uniformly spread the sealant around the countersink.

Abstract: An apparatus for removing the metal wire braid shielding from jacketed electrical wire. It uses a male/female die set and avoids moving the wire braid while cutting. A carousel is provided which readily accommodates different wire sizes.

Abstract: A process and resulting structure for a window typically used on weapons with infrared sensors. The window has a plurality of transparent blocks connected in a mosaic pattern. Between the blocks are slots, that allow a coolant to flow through and cool the window, such that the window does not have a thermal signature.

Abstract: A powered canopy breaker attached to an ejection seat, that fractures a canopy when the seat is ejected. The breaker has a piston that is operatively connected to an explosive cartridge. When the seat is ejected, the piston engages the canopy, pushing the piston a predetermined distance until the cartridge is detonated. The detonated cartridge thrusts the piston back, fracturing the canopy.

Abstract: A crushable, composite, columnar, self-stabilized structure for absorbing energy by progressively reacting compression forces along the axis of the structure. The compression failure initiates at one end and progresses to the second end of the stiffener in a controlled fashion in that at any cross section, the local compression strength at that point is less than the general stability strength of the remaining structure.

Abstract: Ejection seat rails that guide an ejection seat out of a vehicle, wherein the seat has rollers that travel along the rails. The rails are constructed such that the rollers simultaneously disengage from the rails, reducing the amount of tip-off that would occur if the rollers were to sequentially disengage.

Abstract: Disclosed is an advantageous system for heat rejection especially useful in the space environment.

Abstract: A duct for aircraft use which has ease of use and will resist degradation over time. Silicone impregnated cloth is supported by a nylon helix and covered with a protective braiding of KEVLAR.RTM., a commonly used polyamide fiber. The resulting tube can be strung through tight openings. The duct is equipped with a flexible flange for secure engagement. The flexible flange can be collapsed to reduce the cross sectional area for fitting through narrow openings.
