Abstract: In a disc brake, a brake lining support forms a brake ring from one or more support segments, each segment having a lining pad or pads attached to such segment so that the resulting force from frictional braking passes through the attachment device that non-rotatably supports the segment.

Abstract: A fluid pressure operated mechanism for a vehicular disk brake which includes two expansion elements capable of moving in opposite directions to each other. A compensating unit located between the two expansion elements to maintain a given stroke of the expansion elements and eliminate excess play which may be developed as a result of brake lining wear. The compensating unit takes the form of a one piece connecting link having return spring portions engaging one of the expansion elements and frictional gripping portions connected to the other of the expansion elements.

Abstract: Seals for providing sealing contact between the rotary piston and the apexes of the casing of a rotary type combustion engine, compressor, or pump for sealing the several pressure chambers, one from the other or others, during operation. The seals are disposed in radially formed slots at each apex of the housing and are so constructed to permit pressure in the chamber being pressured to be communicated to the rear side of the seal, or the side opposite that which makes sealing contact with the rotary piston, so that such pressure acting on the rear side may assist the spring normally acting against the same side in forcing the seal against the rotary piston with greater pressure and thereby provide a better sealing effect.
