A method of forming metal flake from metal particles comprises charging metal particles, liquid and milling material from a mill and operating the mill to form the metal flake. A portion of the metal flake, liquid and milling material is removed to the mill at a rate substantially commensurate with the charging thereto and milling material is separated from the liquid and metal flake.

The apparatus for grinding of the inner or the outer surface of an annular workpiece, especially a race ring for an antifriction bearing, includes a fixed holder for hydrodynamically centering the workpiece, a rotating driver, and a pressing device. A respective workpiece can be held by the holder and is pressed with one end face by the pressing device against the respective end face of the driver...

A vehicle gearbox has a brake for dampening idle rattling, which is in this case in the form of a conical frictional surface on the low-speed gearwheel on the output shaft and a brake cone carried by a disc fixed to the output shaft. The disc and the cone have coacting structure which presses the cone against the frictional surface when the low-speed gearwheel rotates more rapidly than the output ...
