Abstract: A laminated packaging film useful for skin-packaging electrostatic-sensitive items and protecting the items from electrostatic damage during packaging and while the items are vacuumed, contained, and removed from packages. The film includes a pair of sheets of highly resistive, heat-sealable plastic between which is sandwiched a sheet of conductive, heat-sealable plastic. The film resists the buildup of static charges while the item is being packaged and forms a protective Faraday cage while the item is contained in the package.

Abstract: A highly accurate rapid gimbal assembly method utilizes two fixtures for establishing the critical gimbal assembly parameters of yield and axis of intersection and an adhesive for bonding each mating surface of the gimbal assembly for holding the components of the gimbal assembly in their adjusted positions. The fixtures include an inner/outer gimbal fixture for holding the inner and outer gimbals in relative position for bonding and a gimbal/post fixture for holding the gimbal assembly in alignment on the support post for bonding. These fixtures and assembly method eliminate the need for use of shims between the mating surfaces for establishing alignment of the critical parameters.

Abstract: Apparatus for preventing a missile's rocket exhaust gases from contacting and adversely affecting, such as by overheating, the launch rails from which a missile may be launched. Such apparatus includes an angled member having first and second leg portions, the end of the first leg portion being pivotably secured to the rail. A member having an angled surface is mounted to the second leg portion. Prior to the launching of said missile, the apparatus is in a first operative position such that it is out of contact with said launch rail. When the exhaust gases are emitted from said missile, a portion of the exhaust is incident upon the angled surface which causes the apparatus to rotatably pivot into contact with the launch rail, whereby portions of two surfaces of the launch rail are protected from the exhaust.

Abstract: An electronic controller for an internal combustion engine provides a ratio control signal corresponding to a respective air/fuel ratio, and responds to an air flow signal, a fuel flow signal and the ratio control signal to control fuel flow as to make the ratio of air flow to fuel flow substantially equal to said respective air/fuel ratio. The ratio control signal is developed from a base run ratio control signal as modified in response to various parameters such as engine temperature, manifold pressure, idle, manifold vacuum, fuel temperature, wide open throttle, engine speed, and start. The controller also provides speed-up circuit for promptly responding to change in air flow and dynamic braking for the fuel metering pump. The pump speed circuit includes a range extender.

Abstract: A nosepiece for a drill motor. The nosepiece is adjustable to allow the nosepiece length to be changed rapidly to compensate for different drill lengths. The nosepiece is threaded to mate with threads on the drill motor housing and can be adjusted longitudinally along the motor center line axis. When the nosepiece is threaded along the housing to a desired location it is locked in place by a locking ring keyed to the nosepiece and fixed in position on the drill motor housing by a hand adjustable set screw.

Abstract: A deployment system for a deployable truss structure particularly adapted to space applications which has high structural efficiency and can be remotely operated in a controlled, sequential manner. The truss in its deployed configuration exhibits a "diamond" cross section. Each of the four sides of the structure is essentially a "Warren" truss. Diagonals on the opposite sides of each diamond incorporate a mid-span hinge and the other two diagonals are rigid tubes. When packaged, all elements of the truss are folded so that they are parallel to one another and contained between two guide rails. The guide rails are located on either side of the diamond truss. The horizontal strut connection points or nodes are fitted with rollers that are locked in the guide rails for movement therealong. The deployment initially lifts upright truss members to the vertical position, forming the basic diamond shape of the truss.

Abstract: A clustered munition in a system for low altitude aerial delivery, which releases multiple rocket powered missiles, each having the capability to cruise at a constant altitude and search for a target. Once a target is identified, the missile homes on and strikes the target. In the preferred form the target seeking means is a radiometric seeker operating in the millimeter wavelength range, in which metal or similarly reflective targets stand out against the background and provide a significant signal which is used to program the terminal action of the missile.

Abstract: A dual-path, multicontact connector for a printed circuit board includes two perpendicular groups of contacts and a plurality of internal switches which permit conductivity to be selectively established between one or more pairs of contacts or between either contact of each pair and an electrical circuit on the circuit board. Each contact of a contact pair is included in a respective group of contacts. The perpendicular arrangement of the contact groups allows one group of contacts on the dual-path connector to engage corresponding contact groups on adjacent abutting dual-path connectors. Selective operation of the internal switches in a series of abutting connectors can provide alternate conductive pathways to electrical circuits on any board through the contacts of one or more adjacent connectors.

Abstract: An assembly of fiber optic couplers of substantially identical form in an integrated array comprising two sets of optical fibers arranged side by side across an arcuate surface, epoxied in place, and lapped to develop mating planar surfaces which expose at least partially lapped portions of the respective optical fibers. Preferably, a launch coupler array is provided in which one set of optical fibers is of smaller diameter than those of the other set and is lapped to a depth sufficient to sever the fiber cores. The two lapped faces are then aligned so that one set of severed ends of the smaller fibers is joined with the exposed core portions of the other set of fibers. Selection of fiber size and lapping of the second set of fibers is performed to develop opposed mating portions of individual fibers which are substantially equal in extent and dimensions.

Abstract: An improved airframe body decoupling system for a body gimballed sensor on an interceptor aircraft or guided missile. Body rate gyro information is employed for internal decoupling so as to eliminate decoupling match sensitivity to receiver errors. The true measure of sensor position from the gimballed antenna potentiometer is differentiated and then externally decoupled to produce the desired line-of-sight rate for use by the guidance/control section of the proportional navigation guidance system.
