Title: Vehicle lights brightness regulating device - is used to reduce voltage for rear lamps etc. with headlamps on but can be reversed manually in foggy conditions
Inventor: RITTIRSCH KARL
IPC: B60Q1/14
Filed: 1976-06-25

Title: Flexible shaft coupling system - uses asymmetrical links with fastening pins to accommodate and reduce torques
Inventor: FEDERN KLAUS PROF DR ING
IPC: F16D3/62
Filed: 1977-06-02
Abstract: The coupling (10) consists of two coupling sections, and intermediate leaf spring-like links, for the non-turnable transmission of a torque from one section to the other. The links are formed so that they are asymmetrical to their tangentail longitudinal axis, so that the resultant of all forces transmitted in link centre extend through the axis of the fastening pins, or of axial lines of gravity of the groups of fitting pins of the link ends. Due to this, torques about the link boss at the link ends, which have to be accommodated during fastening of the round pins at the link ends, by friction engagement about the pin axis, canbe eliminated. Alternately, these torques can be reduced by the asymmetrical shaping, relative to a shaping symmetrical to the tangential longitudinal link axis.
