  • Patent number: 4598884
    Abstract: A gimbal-less infrared (IR) target sensor for mounting in an IR transmissive nose cone of a guided missile comprises a fixed, concave, primary mirror mounted coaxially in the base of the nose cone; a fixed, convex, secondary mirror mounted at the focus of the primary mirror; and a plurality of IR sensing units having IR transmissive elements located around the periphery of the primary mirror. A shaped-charge is located aft of the primary mirror. The IR-transmissive elements incorporate IR-conductive fiber optics to transmit the IR signal to detectors aft of the shaped-charge for detection, processing, and missile guidance.

  • Patent number: 4594945
    Abstract: A thin frangible cork barrier conforming to the contour of the burning surface of individual solid propellant grains in a multiple grain rocket motor prevents premature ignition of the protected grain by the heat of combustion of previously ignited adjacent grains and is expelled through the rocket motor nozzle upon ignition of the protected grain. In a second embodiment, the thermal protection afforded by the frangible cork barrier is augmented by bonding to a thermally-protective elastomer layer which is in turn bonded to the propellant grain burning surface. By virtue of the composition and structure of the embodiments, thermal protection is afforded. Upon ignition of a protected grain the thermal barrier breaks up so as to pass readily through the throat of a small motor nozzle.

  • Patent number: 4592280
    Abstract: An improved electro-explosive squib device is disclosed with filter/shield characteristics rendering the device substantially immune to electromagnetic environments, thus preventing accidental ignition of the squib device. The invention provides for adapting existing squibs or constructing new squibs with immunity to the electromagnetic environments while adding only a minimal amount of material to the device, thus minimizing the possibility of personnel injury caused by debris ejected from rocket propellant ignited by the squib device. These benefits are achieved while maintaining reliability and extended shelf life, and at minimal cost of conversion or manufacture of the squib devices.

  • Patent number: 4590741
    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.

  • Patent number: 4588145
    Abstract: An improved missile tail fin assembly. The missile utilizes four tail fin assemblies, each assembly comprising a fitting having three locking portions, each of which comprises a gudgeon having a pair of locking teeth, and a fin having mating recesses for the locking portions. A portion of the material associated with recesses of the two forward locks of each fin is removed, leaving clearances which permit limited rotation about the fin pivot axis in one direction only. When the fin is loaded in a direction to produce clockwise torque, all three locks which form the lock assembly are loaded approximately equal and this locates the elastic axis of the tail lock approximately just aft of the center of pressure which produces a small increase in cant angle with load. When the tail fin is loaded in the direction to produce a counterclockwise torque, the aft lock of the assembly will take all the torque. This moves the elastic axis further aft thus producing a larger increase in cant angle with load.

  • Patent number: 4581977
    Abstract: An apparatus and method for establishing the alignment of heat seeking missiles with the longitudinal axis of a launch pod within which the missiles are contained is disclosed. A housing containing a heat source and collimating optics provides a simulated distant infrared target for the missiles. A tapered probe rigidly attachable to the housing fits securely into a central alignment socket in the launcher pod. The probe is accurately offset from the center line of the alignment socket by the housing to establish the optical axis of the simulated target parallel to the axis of the launcher pod, and in front of the stored missiles. The position of the missile within the launch pod is adjustable to maximize the target signal strength received by the missile from the simulated target to achieve missile alignment with the axis of the launcher pod.

  • Patent number: 4568562
    Abstract: A method for electroless overplating of a conductive metal on printed wiring circuitry components mounted upon a plastic substrate which eliminates deposit metal overgrowth upon the plastic substrate and plastic bonding materials. The substrate and printed wiring are treated by exposure to a tetrafluoromethane plasma environment to chemically passivate, or neutralize, the plastic or adhesive substrate surface areas prior to electroless plating of the printed circuitry elements, thus preventing the establishment of catalyzing ions on the plastic or adhesive surfaces and subsequent lay down of the deposited metal thereon.

  • Patent number: 4566656
    Abstract: A projectile trajectory correction system, the projectile itself including a unique steering arrangement. The projectile, initially part of a shell cartridge, is fired, and its position is automatically sensed. A corrected trajectory necessary to hit a target is calculated and data commands are transmitted to the projectile. The data command signals are sensed by an antenna on the projectile. The antenna in turn generates a signal which is fed to the projectile steering mechanism which is deflected in response thereto to steer the projectile onto the correct trajectory. The steering mechanism includes an elongated rod extending from the rear of the projectile into the surrounding air stream. Deflection of the rod provides the actual steering.

  • Patent number: 4564423
    Abstract: Reusable mandrels for fabricating bumped circuit base sheets may be formed by alternative methods. One method involves the selective etching of a copper sheet to develop pits or cavities at predetermined locations. A thin plating layer is deposited on the base sheet, covering the surface including the depressions to form the mandrel. After passivation of the plated surface, copper is plated thereon to form the sheet with the bumps in place. This sheet is then peeled off the mandrel so that the mandrel may be reused for making subsequent bumped sheets. An alternative method of forming the reusable mandrel involves the selected build-up of a base metal sheet by plating with a compatible material about islands of photoresist. Thereafter, the photoresist is removed, leaving cavities where the islands had been. This surface is then plated with a thin layer of nickel to form the permanent mandrel.

  • Patent number: 4558918
    Abstract: A cable shield to connector back shell termination device includes a back shell of a multi-pin cable connector, a plurality of metallic tubes adapted to receive individually the end of a shielded cable such that substantially full circumferential conductive contact is maintained between each cable shield and a tube, and a cluster of such tubes conductively bonded together and shaped to fit the back shell for conductive bonding to the back shell. A second embodiment employs a conductive sleeve for conductive mounting on the cable shield. Ridges or fins extending generally lengthwise on the sleeve frictionally, conductively contact the metal tubes. In this manner an uninterrupted conductive surface is maintained at the connector. The connector enclosure thus provides a shield against the intrusion of electromagnetic energy in the environment in which the electrical or electronic wiring and circuits must operate.
