Abstract: Integrally molded dust door latches for a video cassette. The latch never needs to be preloaded and includes a planar latch body having a flexing member formed integrally therein to impart inherent spring action to the latch. The latch includes two lateral supports and a first and second projections which enter openings formed in the cassette base. The latch is assembled in the cassette such that the latch can flex or deflect via the flexing member when pressure is applied to one of the projections.

Abstract: A flexible coupling has at least one and more commonly a plurality of diaphragms having a particular profile. The profile has first and second contoured sections. The first contoured section has a radially-inwardly decreasing thickness and extends to near the center of the diaphragm and the second section extends therefrom and has a radially-inwardly increasing thickness such that the bending moment developed by axial deflections is small near the thinnest section or the center of the diaphragm, and the stress levels are minimized throughout the diaphragm. The diaphragm profile as described is analytically optimized to tolerate greater axial deflection and bending before the fatigue and endurance limits of the diaphragm material are reached than has heretofore been the case.

Abstract: An all-steel clutch having at least one eccentric pack of spring plates which holds the clutch halves axially at a distance in the unloaded condition and is so inclined by an acute angle to the axial normal plane that a slight axial displacement of the clutch halves in relation to one another produces a comparatively large angular offsetting, thereby enabling angular displacements caused by loading to be compensated.

The runner plates comprise straight track sections continued with substantially constant profile over their entire length, and between these a middle rib which is continued to each of the runner plate ends with substantially constant profile. The curved track sections connect the straight track sections and pass transversely through the middle rib.

The fluid chamber (24) is defined also by two opposite end walls (25, 28), one (25) of which comprises an annular, nonresilient contact element (37) which is axially displaceable between an active seal position in which it is urged against the seal elements (33, 34) and shoulders (43, 30) on the spindle portion (22) and the fluid chamber wall (20), respectively, and a rest position.

Abstract: A flexible coupling of the type having hubs secured to aligned shafts and connected to one another through the use of a belt surrounding the hubs and engaging teeth on the hubs is improved by forming projections on the interior of the belt which engage complementary receptacles on the hub teeth to prevent the hubs from moving apart in the direction transverse to their rotation.

Abstract: A restriction flange formed integrally on one end of each cylindrical holder in a sliding universal joint abuts the bottom surface of the respective transmitting groove to prevent inclination of the holder relative to a center axis of the outer member of the joint.

Abstract: A rolling bearing arrangement for an anti-locking brake system has a pulse ring with projections directed toward the fixed ring. The surfaces of the projections that activate the pulse generator are cut during the hard working of the bearing ring. The pulse generator is integrated in the rolling bearing arrangement. Thereby, on one hand, tolerance limited operational differences in the amplitude and shape of the pulses are avoided, especially during slow rotational speeds of the bearing ring. Furthermore, external influences on the pulse generator and pulse ring caused by rough roads do not occur due to the hermetic encapsulation of the sensitive components.

Abstract: The assembly comprises a pair of semi-circular steel shells. The inner surface of one shell forms a circular recess. A flat cylindrical annular seal element is seated in and fills the recess. The element is resilient and deformable. It has concentric protruding ribs on its top and bottom surfaces. The seal element is positioned to circumscribe a leaking small hole or crack in the wall of an internally pressurized pipeline. The shells are then circumferentially clamped against the pipeline to cause the element to seal around the leak and to effect tight shell-on-pipe contact. The steel side wall of the recess confines the compressed seal element. The side edges of the shells are then welded together longitudinally and circumferentially to create a permanent pressure vessel sealing and containing the leak.
