Title: Machine for lapping faces of disks -  has carrier plates with gear teeth offset and half plate thickness so that plates can be overlapped
Inventor: WITTSTOCK GERHARD
IPC: B24B37/08
Filed: 1990-09-15
Abstract: The lapping machine has carrier plates (14d) with apertures  loosely holding the workpieces (20d) between upper and lower working disks (22d). Gear teeth (16d) around the circumference of the carrier plates mesh with teeth on outer and inner boundary rings (10,12) so that when one of the rings is driven the carrier plates travel round the machine axis with a planetory motion. A specific feature of the machine is that the teeth on the carrier plates are offset to one side and are less than half the plate' width, allowing the paltes to be overlapped.  By this means the number of carrier paltes can be increased, for example, from five to eight plates. USE/ADVANTAGE - Increased machine capacity of lapping machine smoothing faces of dishes.

Patent DE-4133722-A1 (DE)
Inventor: LEUTNER WILFRIED
IPC: H02P7/29
Filed: 1991-10-11
Abstract: The present invention proposes a process for controlling electric motors with independent excitation and pulse-length modulated drive in which the efficiency of the motor on parking is relatively high and the point of the deflection manoeuver lies within the operative range of the electric motor. This means that the maximum efficiency and maximum output power coincide as closely as possible. The motor is so laid out that the "parking" operating point lies at the maximum efficiency at constant input power. The constant input power from the motor vehicle's own power system ensures that the motor voltage may be varied at will so that the motor characteristic is no longer a straight line. This provides the facility for uniting the maximum power and efficiency.
