Title: Noise reducing assemblies for disc brakes for vehicles
IPC: F16D55/224
Filed: 1976-07-31
Abstract: In a disc brake of the sliding yoke reaction type the noise due to "squeal" or "twitter" is substantially eliminated by resiliently biassing the yoke in grooves in a stationary member so that it engages an upper face of a groove on one side of the brake and a lower face of a groove on the other side. A dampening assembly may be provided between the yoke and a complementary face of one of the grooves. Alternatively the noise may be reduced by providing an abutment of stepped outline on the yoke which engages a friction pad assembly to apply it to the disc when the brake is applied.

Title: Prefabricated concrete component erection and transport anchor - has projecting arm engaging recess in disc coupling head near slit
IPC: E04G21/14
Filed: 1978-05-04
Abstract: The erection and transport anchor is for embedding in prefabricated concrete components. It is used where the surface on the coupling side, perpendicular to its longitudinal axis, does not have the anchor joint end protruding beyond it. There are spreader arms, or similar anchoring units, protruding from the anchor plane, together with a visually regulated coupling aperture for a locking bolt on the coupling head, bounded by an anchor bridge forming the joint end, projecting into a cut-out in the concrete. The cantilevered arm on the anchor bridge engages a recess in the disc-shaped coupling head sited between the slit for the joint end of the anchor and the head central opening. When the anchor is stressed in serving for erection, a fitting surface lies against a surface on a sidewall of the recess inside the coupling head cross-sectional surface.

Title: Low weight reciprocating engine
IPC: F02F1/10
Filed: 1978-10-05
Abstract: An internal combustion V-8 engine is disclosed having an aluminum semi-permanent mold head cast by a low-pressure die-cast process and an iron block cast by the evaporative casting method. The block and head have controlled thickness walls throughout to optimally lower the metal/working volume ratio of the engine. The block employs barrel cylinder walls cast integrally and unsupported except at the barrel ends and at a siamese connection between adjacent barrels the barrels are maintained under a predetermined level of compression to eliminate fatigue failure and suppress sound. The block is sand cast and the head is totally formed with a three piece die and one sand core cluster, except for one passage which is drilled subsequent to casting. The engine is reduced in weight by at least 20% over conventional comparable engines torque and horsepower is improved even though the cooling system capacity has been reduced to less than half that of a conventional cooling system.
