Title: Thin wall rings for radial ball bearings - are suitable for bearings without radial or axial play with rings made from tube
Inventor: WILLERT FRANZ ING GRAD
IPC: F16C33/60
Filed: 1976-05-26
Abstract: In the manufacture of low cost ball bearings, the bearing inner and outer rings are cut from tubes and the edges of the rings are spun over to form rims of circular sections. On the outer bearing ring (1), the rims (2) point radially inward. On the inner bearing rings (4), the rims point radially outward. The balls (3) run on the rim of the rings. To make it possible to remove play between balls and rims, the inner ring is made from two parts (4, 6). The bore of one ring section (6) slides over the outside diameter of the other ring section (4). This makes it possible to remove the play in the ball bearing by pushing the sections together, before joining the two ring sections together.

Title: Cup seal for hydraulic brake cylinder - has coil spring carried longitudinally of cylinder to bias seal outwardly
Inventor: FRANZI RICCARDO
IPC: F16D65/22
Filed: 1976-06-14
Abstract: The piston seals for hydraulic brake cylinders for automobiles provide adequate sealing at low pressure and minimise the loss due to friction. A brake cylinder (2) contains two pistons (7) that are moved outwards against brake shoe actuators (16) by fluid pressure applied to the centre section (8). A close coil spring (14) operates against pressure plates to maintain a specified distance. The pressure plates operate against cup shaped seals (9) with a relatively thin inner section (9) and substantial annular section (10). The periphery has a radiused section to contact the cylinder bore. In operation the light spring force on the thin inner section maintains sufficient contact pressure to provide efficient sealing. Fluid pressure applied during braking compresses the seal against the bore to maintain the seal.

Title: Evaluation of timing signal on tape or film - includes reading out at one of timing frequencies stored data signal
Inventor: TRISSL KARL-HEINZ DIPL PHYS
IPC: G11B27/32
Filed: 1976-09-29
Abstract: The recording medium is possibly provided with a perforation for transport purposes, and the timing track is scanned, generating a corresponding electric code signal which is decoded, delivering a data signal containing the coded information, and a data timing signal containing the code signal period. The recording medium movement is mechanically or electrically scanned generating two phase shifted pulse trains. The pulse repetition frequency of both pulse trains is proportional to the recording medium transport speed, and the sense of the phase shift between the pulse trains gives the direction of its movement. Data signal is electrically stored at the date timing frequency, and read out at the frequency of one of the pulse trains in the same sense as during storage. The read out signal is processed at the frequency of one of the pulse trains.
