  • Patent number: 6896305
    Abstract: A high-load capability non-explosive cable release mechanism for retaining the adjacent ends of two cables and releasing them upon receiving a signal from a remote source. The cable release mechanism has a casing for housing two non-explosive actuators (NEAs), which also has a center bore for housing a jaw and ramp assembly. Each NEA is connected to the jaw and ramp assembly for independently operating the jaw and ramp assembly to retain or release the proximal ends of the two cables. Upon receiving the signal by any one or both of the NEAs, the jaw and ramp assembly will release the adjacent ends of the two cables from the casing.

  • Patent number: 6193535
    Abstract: A connector assembly which includes conventional components that are well known in the connector assembly field but which includes within it an improved ceramic deadface which is located at a front face plate on an interior portion of the connector assembly. If the connector is separated so that the deadface is exposed, then in the event that location with the deadface exposed faces an area of extreme high temperature, the deadface preserves the connector assembly and prevents internal components including plugs and wires from being destroyed or melted. The connector assembly involves the incorporation of a novel ceramic deadface on the interior portion of the connector assembly which is able to withstand extreme high temperatures.

  • Patent number: 5752847
    Abstract: A plug (12) and receptacle (14) connector has its unmating force determined in part by a generally circular helical spring (20) received in a slot (22) on one of the connector parts which resiliently resists separation by engaging a ridge (18) on the other connector part. A pressure ring (26) also exerts a selectively adjustable separation force on the connector parts serving to fine tune the summation actual separation force to a precise predetermined value.

  • Patent number: 5748066
    Abstract: A controller (24) is provided to selectively release an initiator (12) having first and second members (14,16) that clampingly engage an object (18) preventing it from moving in an urged direction. A spring wire coil (20) holds the members (14,16) tightly about the object, one coil end affixed to one of the members and the other coil end is held by a pair of link wire loops (82,86) of the controller (24) which is also removably secured to one of the members (14,16) by a bolt (36). When it is desired to release the object (18) an electric current is passed through the link wire loops (82,86) of sufficient magnitude to cause the loops to break, releasing the coil (20) to unwind and, in turn, release the object for urged movement.

  • Patent number: 5438173
    Abstract: The present invention is a cell bypass switch particularly designed for aerospace applications. The cell bypass switch can sense a battery cell failure and automatically opens an alternate path around the failed cell, bypassing the failure and allowing the remainder of the battery system to continue its function. The cell bypass switch is designed to be placed in parallel with the battery cell it protects. The present invention includes two electro-mechanical actuator assemblies which are mounted on the top end of the housing for operating two plungers respectively. Each of the electro-mechanical actuator assembly includes two spool halves which are held together by a tight winding of a restraining wire that terminates in a bridge wire connecting two electrical terminals of the electro-mechanical actuator. Each spool, by virtue of the restraining wire winding, can restrain a spring loaded plunger.
