Abstract: A clutch release bearing for use with a friction clutch for automotive vehicles having a ring-shaped spring release member. The clutch release bearing is formed as an anti-friction bearing wherein one of its race members has a portion extending axially away from the rolling bodies. The extending portion projects a distance sufficient to be inserted within the bore of the spring release member and to pass behind the rear wall and engage therewith. The race members of the bearing are made of sheet metal and are folded to provide substantially radial walls adapted to engage the front face of the spring release member or the clutch release actuating member. The projection of the one race member may be cylindrical or it may project as a ring-shaped body having slots forming resilient fingers interengaging with the arms of the spring release member.

Abstract: The actuator assembly is a unitary structure comprising a self-braking rotary power unit and a spring clutch mounted on a frame and interconnected so that the spring clutch transmits the rotary driving force of the power unit to a load to thereby effect its movement in one direction, the power unit and spring clutch co-acting when the power unit is inoperative to hold the load in a selected position. An electro-magnetic device coacts with the spring clutch to cause the spring to disengage and allow the load to move in a direction opposite of the one direction.

Abstract: A self-locking hinge for use as a pivotal connector between two pivoted members and adapted to lock the members in a fixed angular relation. The hinge comprises a pair of circular plates that are rigidly affixed to opposite faces of one member and rotatably connected to the other member. The circular plates are used to laterally support both of the members and to guide the other member as it is rotated from a folded position to a fully extended position. The hinge is locked in the fully extended position by means of a locking ring that is slidably engaged with the other member. When such other member is fully extended, the ring engages corresponding locking indentations at the periphery of the circular plates and thereby blocks the movement of the other member in one angular direction. The movement of the other member is blocked in the opposite angular direction due to the abutting of the hinge ends of the members.
