Abstract: A seal assembly (10) comprising a sealing body (40), a shoe (42), a first collar (44), and a second collar (46). The shoe (42) is positioned within a space defined by radially inner surfaces of the sealing body (40), the first collar (44) is positioned on a first axial side of the sealing body (40), and the second collar (46) is positioned on a second axial side of the sealing body (40). These components (40, 42, 44, 46) collectively form inter-component sealing surfaces, pocket sealing surfaces, gate sealing surfaces and/or part sealing surfaces which prevent the infiltration of outside fluid into, and the escape of operative fluid from, a fluid coupling.

Abstract: A composition and process for forming an electrodeposited coating comprising a co-deposit of a metal and MCrAlY particles. The composition includes a metal and a MCrAlY particles, and the electrodeposited coating comprises a metal matrix and MCrAlY particles dispersed in the matrix. In one aspect, a coating is provided that exhibits excellent oxidation resistance and tribological characteristics at high temperatures, including up to at least about 1350° F. A high temperature coating may comprise a nickel/cobalt alloy matrix comprising MCrAlY particles and chromium carbide particles dispersed in the nickel/cobalt matrix.

Abstract: An engine exhaust system comprises duct pieces and a thermally expandable sealing joint for interconnecting their adjoining ends. The sealing joint comprises a tubular body including a first axial end portion, a second axial end portion, and a bridge portion extending therebetween. The first end portion is at least partially positioned within a female recess of the first duct piece and the second end portion is at least partially positioned with a female recess of the second duct piece. The bridge portion can extend across a gap and/or it can be positioned partially within female recesses. Upon thermal activation, the sealing joint radially expands permanently to engage the inner radial surfaces of the duct pieces.

Abstract: An engine exhaust system comprises duct pieces (201, 202) and a sealing joint (30) for interconnecting their adjoining ends. The sealing joint (30) comprises a one-piece tubular body (31) including a first axial end portion (331), a second axial end portion (332), and a bridge portion (34) extending therebetween. The first end portion (331) is at least partially positioned within a female recess (231) of the first duct piece (201) and the second end portion (332) is at least partially positioned within a female recess (232) of the second duct piece (202). Depending upon the thermal expansion-contraction conditions in the exhaust system, the bridge portion (34) can extend across a gap (24) and/or it can be positioned partially within female recesses (231) and (232).

Abstract: A process chamber 10 comprising a container (12), a lid (14), and a sealed interface (16) therebetween. The container's interface surface (30) and/or the lid's interface surface (32) includes at least one groove (36) in which a seal (40) is situated. The seal (40) comprises an elastomeric element (50) and a metallic element (60). The elastomeric element (50) and the metallic element (60) can be arranged and adapted to seal the chamber's interface (16) sequentially during its conversion to a sealed condition. And/or the elastomeric element (50) and the metallic element (60) can be arranged and adapted to seal the chamber's interface in series once the lid (14) is in its sealed condition.

Abstract: A spring seal for sealing in high temperature applications includes a jacket and a spring member disposed within the jacket. The spring member is constructed to control a sealing load or spring rate of the spring seal relative to opposing flanges while the jacket is constructed to provide a sealing surface relative to the opposing flanges. The spring member is manufactured from a cast blade alloy, thereby allowing the spring member to maintain its spring back characteristics at relatively high temperatures of about 1300° F. and greater. Accordingly, the spring member minimizes the formation of a leak path between the spring seal and the opposing flanges. In one embodiment, the spring member is manufactured with a substantially U-shaped cross-section. With such a configuration, the spring seal provides substantially balanced, opposing forces on the jacket to minimize the formation of gaps between the spring seal and the flanges.

Abstract: A seal (40) for sealing an interface between a container and a lid of a process chamber. The seal (40) comprises a metallic or polymeric sealing element (50) and an elastomeric sealing element (60) that are arranged to seal the interface in series, with the metallic or polymeric sealing element (50) being situated to encounter processing activity upstream of the elastomeric sealing element (60).

Abstract: Seal (20) is formed in two halves (22A, 22B) mated along a transverse centerplane (502). Each half faces outward from an associated side of centerplane (502) and includes centrally apertured (100) metal body (22A, 22B). Each body has an outwardly projecting hub (24A, 24B) having an outward-facing engagement surface (25A, 25B). A web (26A, 26B) extends radially outward from the hub (24A, 24B) to a perimeter and has interior and exterior surfaces. Bodies (22A, 22B) are secured to each other by an annular weld (40) to form a seal body. A longitudinal separation between the engagement surfaces (25A, 25B) is compressible via flexing of webs (26A, 26B) from relaxed separation to a range of compressed separations. In the compressed separation, the surfaces are sealingly engaged to respective ones of the first (44A, 44B) and second (45A, 45B) conduits. On each side of seal (20) there may be two polymeric sealing rings 44A, 44B) and an annular retainer (66A, 66B).
