Patent DE-2534208-A1 (DE)
Title: Protective circuit for fuel fired vehicle heater - having pump operated by blower circuit with overload protection
Inventor: WIESNER JOSEF PETER
IPC: B60H1/22
Filed: 1975-07-31
Abstract: The fuel fired vehicle heater has a blower motor(M1) and a pump motor(M2) both linked to a protection circuit. The pump motor is fitted with a relay (Re11) operated by the blower current so that the pump only runs when the blower is operating. This prevents fuel swamping. The blower circuit is fitted with a current overload protection in which a thermal device (3, 4) operates a second relay(Re12) to switch off the complete system if the blower motor stalls. In order to cater for large starting currents in the blower motor in extreme cold, the thermal rise time of the second relay is chosen sufficiently long. The blower cannot operate until the thermal element cools down.
Patent DE-2540348-A1 (DE)
Title: Low friction load nut on lifting spindle - is self locking in case of power failure
Inventor: NUSSBAUM HANS DIPL ING
IPC: F16H25/22
Filed: 1975-09-10
Abstract: A load carrying nut (2) on a vertical load lifting spindle (1) has a number of equally spaced screw rollers (8) which are in mesh with the thread of the spindle (1). To reduce friction between nut and spindle, the screw rollers are located on pivot pins (3) by means of roller bearings (4). Axial thrust bearings (7) transmit the load from the nut body (2) to the screw rollers (8). A one way clutch (6) between the pivot pin (3) and the screw roller (8) prevents the rollers from rotating about the pivots when the load is lowered. This ensures that normal friction between nut and spindle occurs so that in case of a power failure, the nut would be self jamming.

Title: Heating unit for various types of surfaces - consists of continuous helical plastics tube
Inventor: SCHAEFER RAINER
IPC: F24D3/14
Filed: 1976-01-22
Abstract: The heating unit is for all types of surfaces, using heating tubes with a fluid heat carrier, fixed to a structural steel webbing.

Title: Clip-on inductive pulse pick-up - has compression springs between clip jaws and plastic holders
Inventor: HEILMANN WOLFGANG ING GRAD
IPC: G01R1/22
Filed: 1976-02-20
Abstract: The halves of a ferrite core respectively set in the jaws of a pick-up clip are held in plastic holders loosely mounted in the respective clip jaws. There are compression springs between the holders and the jaws that are weaker than the spring that pulls the clip jaws together.
