  • Patent number: 6452105
    Abstract: A coaxial cable structure incorporating a physical interruption in the outer jacket or sheath of the cable. This interrupts the continuity of the outer conductor and serves to block DC (direct current) and low frequency electrical signals. Also, it greatly reduces heat transmission along the cable. The interruption is achieved by placing a specially fabricated stub in series with the coaxial cable. The resulting coaxial cable assembly acts like a band-pass filter which, although blocking DC and lower frequency electrical signals, is able to transmit RF (radio frequency) signals at selected frequencies. The entire assembly, including the stub, can be made hermetic.

  • Patent number: 6446906
    Abstract: Pyrotechnic actuator cover/fin release system designed for high G forces of gun-launched-systems. As safety feature, system allows the pyrotechnic actuator to be installed as one of the last steps of the final testing sequence and removed safely on disassembly. A first cam action develops initial ejection. Subsequently firing the pyrotechnic pushes both the fins and the covers outward via a second cam surface. The release system both holds covers securely latched until commanded to release and then unlatches covers prior to pushing them open. The cover eject sequence results in the flight forward edge of cover being kicked into air stream. Thereafter the cover is lifted and rotates about its aft release hinge until, at about 30 degrees of rotation, the hinge disengages. The fins then are driven into the fully deployed state by a spring and piston/wedge mechanism on the actuator shaft.

  • Patent number: 6315239
    Abstract: An integrated system for missile steering, which uses both jet reaction control (JRC) and aerofin control systems, is provided with a variable coupling mechanism for adjusting the relative responsiveness of the two systems in accordance with the pressurization state of the JRC system pressure chamber. In one embodiment, the pivoting action of a joystick which actuates the gas flow control pintles of the JRC system is permitted only under sufficient pressurization of the pressure chamber. In a second embodiment, the extent to which the pintles protrude from their controllable housings is adjusted according to the pressure in the pressure chamber. In this manner, when JRC is undesirable or is unavailable, the missile aerofins are permitted their full range of motion without being constrained by the pintles.
