Abstract: A high pressure plastic pipe coupling in which a formed in situ annular wedge converts axial loads on a flanged ring to compressive hoop stress loads on a reinforced resin pipe.

Abstract: A fixed cavity, integral bonded, flexible coupling for joining ferrule terminated tubing ends in an aircraft environment in which a clam shell coupling is spring loaded at its hinges so as to bias it toward an open configuration. The clam shell coupling latches in a closed configuration by means of a plurality of latch pawls engaging latch pins, with the latch pawls being spring-biased into engagement with the latch pins.

Abstract: A snubber having a seal assembly in which a seal having a generally U-shaped cross section encircling a reciprocating rod is engaged with a separate integral wedge element in such a way that radial loads are applied so as to force the outer lip of the seal outwardly and the inner lip of the seal inwardly. The outwardly directed radial load is uniform around the entire seal, and the inwardly directed radial load is likewise uniform around the entire seal; however, the inwardly directed radial load is greater than the outwardly directed radial load.
