Title: Radial piston pump for liquid discharge - has plastic impact absorbing insert in base of piston
Inventor: MUETSCHELE HANS ULRICH DIPL IN
IPC: F04B1/04
Filed: 1973-07-20
Abstract: A cylinder with spring loaded inlet and discharge valves contains a piston which is given a reciprocating motion by a cam on the drive shaft. The piston is kept against the cam by the fluid pressure in the cylinder. The base of the piston has a recess containing a plastic insert, which is longer than the piston recess. In normal operation the insert is compressed so that the base of the piston rests on the cam. Without fluid ion the cylinder, the insert expands and takes up the space between piston and cam so that initial entry of fluid does not cause a shapr knock of piston against cam.

Title: Finishing tooth flanks of hardened gear wheels - gear hob with relieved cutting blades cleans out tooth valleys
Inventor: KIMURA KANBEI
IPC: B23F5/22
Filed: 1974-01-04
Abstract: Procedure for finishing the tooth flanks of a shaved and hardened gear wheel comprises the step of working opposing tooth flanks with a gear hob whose cutting blades clear out the tooth valleys and whose side edges, used for the shaving of neighbouring tooth flanks, are relieved rearwards at an angle of between 25 deg. and 60 deg. relative to the rotational direction of the hob. The cutting resistance and the rubbing between the workpiece and the cutting edge which appear before the cutting process are reduced as a result of the lowered angle of cut. The generation of heat is prevented and the cutting process is almost free of thrust.

The contact blade may have tapered ends to facilitate entry into the fixed jaws, and plated contact faces. Part of the inactive area of the electrode may be cut away to allow better cooling oil circulation.
