A bolt retention clip for a gas turbine engine rotor assembly includes a main plate section defining a central aperture, the central aperture sized to receive a bolt therethrough. Also included is a pair of bolt retention tabs extending away from a first face of the main plate section to axially retain a head of the bolt. Further included is a first clip retaining tab extending away from the first face of the main plate section for insertion into a groove of a rotor structure. Yet further included is a second clip retaining tab extending away from a second face of the main plate section for engagement with an edge of the rotor structure.

A torsion washer of the present disclosure includes a base portion and an elastic unit extended from the base portion. The elastic unit includes an external elastic arm and a torsion-adjusting arm arranged inside the external elastic arm. A space surrounded by the base portion and the external elastic arm is divided into a hole and a slot, in air communication with the hole, by using the torsion-adjusting arm. A distance, i.e., a radius, between the external elastic arm and a center of the hole is larger than a distance, i.e., an interference distance, between the torsion-adjusting arm and the center of the hole. Moreover, the present disclosure provides a torsion device including a plurality of the torsion washers and a shaft coupling through the holes of the torsion washers, and the shaft is configured to selectively contact each torsion-adjusting arm.

Some implementations can include step pegs having safety locks.

An assembly for operating a device, such as a variable vane, has an arm, a stem to which the arm is connected, the stem having a slot, and a member having a tab which fits into the slot.

A bushing includes an upper collar with a lower sheath and an annular shoulder intermediate the collar and sheath. The collar has a plurality of spaced apart notches and the sheath has a plurality of spaced apart slits that may be circumferentially aligned with the notches. The sheath has a plurality of spaced apart ribs projecting outward circumferentially offset from the slit for assisting in maintaining the sheath within a hole in a fastener with the annular shoulder against the fastener. A securing member with an elongate shank extending from a head with a distal portion is maintained in the longitudinal opening in an upright position aligned with the hole. As the fastener is driven longitudinally through the opening and hole, force from the fastener causes the bushing to break away and yields direct contact between the securing member head against the top surface of the fastener.

A support member is for supporting a conductive member such as an electrical wire and is for installation in an automatic transmission, and includes a main body portion made of a resin and plates that are made of a metal and are to be fixed to the body of the automatic transmission via bolts. The main body portion has attachment portions to which the plates are attached, and elastic lock portions that project within the attachment portions and have elasticity capable of restricting removal of the plates from the attachment portions.

Disclosed is a space saving, heat-damage reducing, mess-avoiding hanging apparatus for cookware or bakeware closures and related methods. In use, the apparatus may be (a) contained within cookware/bakeware while the closure or lid is closing the cookware/bakeware or (b) used to hang the closure or lid on to the bakeware/cookware in a handle-out orientation via laying the hook of the apparatus over a lip or edge of the cookware or bakeware.

A clamping element (9) is specified configured to be pressed to a baseplate (2) of at least one power semiconductor module (1) comprising a mold (4), comprisingat least one contact area (10) being configured to be in direct contact to at least one clamping area (7) of the baseplate (2) being free of the mold (4), andat least one recess (11) provided in the baseplate, whereinthe recess (11) and the contact area (10) are configured to face the baseplate. Further, a method for producing a power semiconductor device is specified.
