  • Patent number: 10718220
    Abstract: In accordance with some embodiments of the present disclosure, a gas turbine engine is presented. The engine has at least one turbine stage and each stage has a turbine disc concentric with the axis of the engine. The turbine disc has a turbine arm positioned axially from the disc and rigidly attached thereto. The drive arm is also concentric with the turbine axis and has an outer surface. The turbine stage also has a cover plate concentric with the turbine axis and covering at least a portion of the turbine disc. An arrangement of turbine blades are positioned around the periphery of the disc and are retained on the turbine disc at least partially by the cover plate. The system includes a spanner nut, and threads on a portion of the turbine drive arm. The spanner nut is threaded onto the turbine arm which applies an axial force on the cover plate, thereby retaining the cover plate.

  • Patent number: 8950755
    Abstract: A handheld tool is for facilitating installation of a resilient, elongate, generally rectangle-profiled gasket designed to tightly fit inside and along the partially obstructed perimetric channel of a watertight doorway onboard a marine vessel. As typically embodied, the inventive tool includes a straight handle (e.g., shaft or rod) and a head. The head includes a right-triangle profiled section and an L-shape-profiled section. The handle is perpendicularly connected to the hypotenuse surface of the right-triangle profiled section. The L-shape-profiled section has two interior surfaces forming an interior right angle that faces away from the hypotenuse surface. The bisector of the interior right angle is parallel to the handle and perpendicular to the hypotenuse surface. A user holds the inventive tool by the handle, controls the gasket so that a rectangular corner portion of the gasket fits inside the L-shape-profiled section's interior right angle, and forcefully manipulates the gasket into the channel.

  • Patent number: 8942001
    Abstract: A seal structure for an electronic control device having a circuit board housed in a watertight space a housing that is formed by fitting a plurality of fitting members together, has first and second seal portions which are formed at a fitting surface portion between the fitting members that are fitted together. One side of a pair of the fitting members of each of the first and second seal portions is provided with a seal groove, the other side is provided with a protruding line. An auxiliary seal groove and an auxiliary protruding line are formed on opposing surfaces of the seal groove and the protruding line at a merged part where the first and second seal portions meet each other. The auxiliary seal groove and the auxiliary protruding line continuously extend from the seal groove up to an end surface of the protruding line.

  • Patent number: 8936249
    Abstract: An increased resilience seal utilizing a sealed gas filled inner chamber in a bellows spring that functions as both a mechanical spring and a gas spring to provide a more constant level of separation force between two face plates to provide a seal between two mechanical components such as those found in an aircraft jet engine. The bellows spring is made of a plurality of walls that are joined together in a pressurized chamber that is filled with a gas, such as an inert gas. In alternative embodiments, the bellows spring is made of walls that are shaped and oriented to optimize the operating characteristics of the bellows spring when the pressure is increased in a sealed inner chamber in response to elevated temperature. In one embodiment, the walls forming a portion of the chamber overlap to optimize the geometry of the bellows spring.

  • Patent number: 8910950
    Abstract: A sealing gasket that provides a seal between two members. The gasket includes a base at one end of the gasket and a gutter-forming surface at the opposite other end of the gasket. There is a pair of sides that join the one end and the opposite other end of the gasket. The sealing gasket is movable between a compressed condition wherein the gasket provides a seal between the two members and an uncompressed condition wherein the gasket does not provide a seal between the two members. When the gasket is in the compressed condition, the gutter-forming surface deforms to form a gutter along the one end of the gasket.

  • Patent number: 8893909
    Abstract: The present invention relates to a pressure vessel (1) for a high pressure press, wherein the pressure vessel comprising a first sub-cylinder (4), a second sub-cylinder (6), pre-stressing means (8), and a securing member (16). The first and the second sub-cylinders (4, 6) are axially connected to form a cylinder body (2) for enclosing a high pressure medium. The first sub-cylinder (4) is in an outer wall provided with a first seat (22) for receiving a first part (24) of the securing member (16) and the second sub-cylinder (6) is in an outer wall provided with a second seat (26) for receiving a second part (28) of the securing member (16). The securing member (16) is fitted in the first and second seats (22, 26). The securing member (16), and the first and second scats (22, 26) are arranged such that the securing member (16), and the first and second scats (22, 26) cooperate to prevent separating axial movement between the first and the second sub-cylinders (4, 6).
