A clamp assembly includes a pair of segmented leg members that are tandem-operated to capture and hold a circuit board or module in and to chassis slots. The leg members each comprise a plurality of distinct wedge segment having complementary, confronting wedge surfaces.
5192384 Methods for forming composite tubing having tapered ends March 9, 1993
Reinforced composite tubes having integral tapered ends are formed on mandrels which are tapered at each end. Reinforcement fabric is first conformed to the mandrel with at least one end of the fabric structure retaining an opening therein. The mandrel is disassembled and removed thr
5152556 High temperature tubing joint with threaded, split collar October 6, 1992
A connector system for joining a male tube to a female tube comprises an axially-split nut which extends across the region being joined. The female tube is externally threaded and mates with internal threads on one end of the axially-split nut. A shoulder formed in the other end of the
5137259 Self adjusting energized valve seal August 11, 1992
A seal and seat for ball valves is a circular, elastomeric open torus which is fitted between the ball element and the housing. The open torus has within it, a substantially "v" shaped spring that is fitted within the "u" shaped opening of the torus. In normal operation, the spring membe
5104636 Method of making aluminum oxide precursors April 14, 1992
Aluminum oxide ceramic composite articles having high flexural and tensile strength are produced by introducing a liquid aluminum oxide precursor material into a ceramic reinforcement fabric, curing the precursor material at an elevated temperature, and converting the cured precursor
5082354 Optical switch and color selection assembly January 21, 1992
An apparatus and method for providing optical switching or color selection capability uses cholesteric liquid crystals which reflect and transmit circularly polarized light and a variable wave retarder element together with phase reversing mirrors which recapture and recombine the reflec
5056678 Access port sealing device October 15, 1991
An access port cover is fitted with a sealing plug that is adapted to fit inside a conduit to provide an occluding seal. The conduit is also fitted with an inner flap that is automatically closed and latched when the cover is closed and latched. In a preferred embodiment, a ridge in the
5050240 Air cushion helmet support and ventilation system with air pressure regulator September 24, 1991
An air cushioned safety and/or display helmet. A thin cushion of air between the wearer's head and the inside of the helmet supports the helmet and distributes the helmet's weight evenly thus preventing development of pressure points and corresponding wearer fatigue. When used in a high
4955091 Method and apparatus for a vacuum assisted toilet system September 11, 1990
A non recirculating, low volume toilet system for aircraft includes a interim storage tank connected to the toilet bowl. A waste drain leads to a gate valve which opens to a vacuum assisted luid gas separator. The separator is connected to the main waste tank. In a first embodiment, the
4773445 Solenoid valve September 27, 1988
An improved solenoid poppet valve includes an endless magnetic gap loop which overlies the valve chamber. The axis of the poppet valve intersects the magnetic gap and can be self centered by the energizing of the solenoid. The valve chamber can be sealed from the solenoid coil and ma
4770500 Method and apparatus for multi color display September 13, 1988
An apparatus and method for producing a color display from a substantially monochromatic source utilizes a liquid crystal cell combination together with a plechroic filter to differentially polarize the light components comprising the light emitted from the source. The liquid crystal cel
