Abstract: The invention comprises an automated system 10 for the accurate positioning of movable parts bins 16 in relation to a preferred fixed location 26. The automated system consists of a number of movable parts bins 16 arranged on a conveyor 14 which is driven by a drive mechanism 18. The drive mechanism 18 controllably moves the conveyor 14 and therefore the bins 16 to desired locations in association with a coarse position sensor 24 and a final approach sensor 26. Both the sensors and the conveyor drive mechanism are interconnected with an electronic controller 28. This electronic controller monitors the position sensors in order to control the drive mechanism in a manner which positions the preselected parts bin at the desired location.

The laser diodes 26 are mounted to ceramic plates 25 that are excellent heat extractors and electrical insulators. The ceramic plates 25 have steps 32, 34 which permit diode mounting without plate to plate interference when the plates are assembled into the arrays 12. Conductive coatings on selected portions of the ceramic plates is used to electrically connect the diodes.

Abstract: A seal assembly 34 for forming an air seal around conduits or accessories 32 crossing aircraft engine bypass ducts 30. The seal assembly comprises a seal retainer plate 40, a seal plate 36 and a seal ring 44. The seal ring 44 has two opposingly sprung legs which seat and form air seals at the duct wall 30 and the seal plate 36.

Abstract: An automatic tape laying device for applying structural tape 24 to an underlying structure in order to fabricate a composite part. The tape laying device comprises a tape laydown head 10 and a plotting mechanism 60. The tape laydown head has two tape laying rollers 12, 14 arranged side by side and independently controlled. Generally, the tape laying rollers 12, 14 apply tape sequentially to a form as when the tape head is being moved back and forth. The tape head is oriented with a rotary orientation mechanism 90. A separate supply structure 70 parallel to the tape head 10 houses tape supply reels 76, 78 and tape cutting means 84, 86.

Abstract: A robot gripping device 10 for holding and gripping a variety of electronic components. The robot gripping device comprises a guide frame 12, a drive motor 34 and gripping blocks 24, 26 having fingers 42, 44. Finger 42 has prongs 66, 68 and 70 on fingertip 60. Finger 44 has prongs 76 and 78 on fingertip 62. The fingertips 60, 62 accommodate axial resistor-type components at v-grooves 80 and radial capacitor-type components are accommodated by fingertip portions 82, 84, 85 and 86. Cylindrical can shaped components are accommodated by a slight beveling at fingertip portions 82, 84, 85 and 86 as well as a set back of portion 83 on prong 68. The fingers are capable of controlled movements to various centered positions by means of motor 34. When the fingers are brought together they interlock.

Abstract: A liquid spring shock absorbing device 8 comprising an hydraulic piston 10 with an integral surge valve 14. The hydraulic piston 10 is positioned within a fluid filled piston housing 12 and is made up of a piston body 16, a spring reaction plate 22 and a piston heat 18. A large annular spring 30 and a small annular spring 36 are positioned adjacent to the spring reaction plate 22. Short duration shocks are transmitted by the fluid to cause rotation of annular spring 36 which opens relief valve port 42. Long duration, high intensity shocks cause compression of both annular springs, opening of relief valve port 42 and movement of hydraulic piston 10.

Abstract: A direct air cooling system 12 for electronics carried by aircraft. The cooling system provides a submerged air scoop 16 which directs outside air to several electronic modules 14. The air flows through passages 76 in the modules 14 which are adjacent to circuit boards 74, 78 bearing discrete electronic components 88. A foil layer 86 and aluminum fin stock help transfer heat from the electronic components to the directed air. Heated air is then exhausted through exhaust port 24 or 28.

Abstract: A rocket exhaust probe 10 for collecting particulates from a rocket exhaust plume. The probe comprises a tungsten nose tip 18, a tip holder 20, a probe body 22 and a tail section 24. Rocket exhaust gas enters the probe at the nost tip inlet 32 and passes into a mixing chamber 36 where the exhaust gas mixes with an inert cooling gas that cools and decelerates the exhaust gas. The mixture of exhaust gas and inert gas then passes into a diffusion chamber 50 where it further cools and decelerates before passing through a submicron particle collection filter 52.

Abstract: A fiber optic cable storage device 10 for securing fiber optic cable 36 with connectors 34, 35 on a spool 12. The spool 12 includes a drum 13 with a flange 16 and slot 15 that allows for stress free routing of cable 36 and connectors 34, 35 to a connector storage area 18. The connector storage area includes a drive plate 20 for mechanically reeling of the cable and connector holders 29, 30 for holding fiber optic cable connectors 34, 35. A removable cover 42 is used to trap the cable connectors 34, 35 in the holders 29, 30.

Abstract: A dual mode heat exchanger 10 for cooling airborne electronics 12 through a cold plate 14. The heat exchanger either radiates heat to air through radiator fins 18 or absorbs heat by evaporative cooling. A liquid coolant contained in grooves 16 of the cold plate 14 boils at a preselected temperature and thereby absorbs heat energy. Vapor released by the boiling liquid is exhausted through a hydrophobic filter membrane 24.

Abstract: A light-weight hyperbaric oxygen therapy hood assembly comprising a neckdam and hood having a gas inlet and outlet. The neckdam comprises a diaphragm which can be varied from an open to a closed condition for sealing of the neckdam around the neck of the patient, the diaphragm being concentric to the hood and neckdam. An inflatable bladder is providable at the back of the hood. A check valve is affixable to the gas outlet of the hood.

Abstract: Modular detonator device for use in series array line detonations. The detonator device comprises a case, a coupler and a base. A first electrical contact is disposed on the base and is coupled through an exploding bridgewire and the coupler to the case, where the external wall of the case comprises a second electrical contact of the device. The device may be battery-like in external configuration to facilitate end-to-end placement of a multiplicity of the device in a practically infinite series array, with external wiring necessarily being connected only to the lead and the trailing end of such series array.
