Abstract: A joint restraint assembly for connecting pipe ends together, or to other objects, which includes a body encircling the pipe. The body has a plurality of cavities adjacent to the pipe with a segment configured to fit into each cavity. One or more threaded bores are disposed through the body into each cavity. A threaded bolt extends through each threaded bore to engage the segment in that cavity, and to pre-load the segment against the pipe when assembled thereon. Mechanical or pressure loading, tending to pull the pipe out of the restraint assembly, causes the segment to self actuate, and the application of increasing load causes a proportional increase to the force engaging the segment to the pipe. The joint restraint assembly reliably accommodates comparatively high levels of mechanical loading and/or pipe internal pressure, and does so without relying upon the limited force produced by the threaded bolt pre-load on the segments at the time of assembly.

Abstract: An arrangement is set forth for mounting knife edge seals on a rotating bladed disk for sealing cooperation with sealing lands on a ring, fixed against rotation, connected to the inner ends of adjacent vanes. The knife edge seals are fixed to a sealing member which is removably positioned on a cylindrical-like flange on the disk. Radially mounted headed pins, held in position by centrifugal force during engine operation, fix the sealing member to the disk flange, while a pin retaining ring holds the pins in place when the disk is at rest.
