Title: Spring wire contact for cross-bar switches - has contact element at free end of spring contact in wire axial direction
Inventor: DOST WILLIBALD
IPC: H01H1/06
Filed: 1973-06-29
Abstract: The contact element is so applied to the free end of the contact spring in the wire axial direction that the spring end is not surrounded by the same as would be the case with a sleeve. The contact element may be a ball of a contact alloy welded to the spring end. A spherical head may be formed by upsetting on the free end of the contact spring, and the head may be galvanically coated with a contact surface. The contact is intended for telephone relays requiring contact rivets of rare metal, possibly in the form of double contacts. Since such contacts are not easily welded in miniature contact spring sets, the contact spring with the upset head removes the drawbacks.

Title: Electronic control for car fresh air fan - has motor current regulated for air pressure forced into car during travel
Inventor: FEHR WERNER
IPC: H02P7/288
Filed: 1973-08-16
Abstract: The electric fan motor is controlled by an electronic circuit to give a set supply current in relation to the selected fan speed. This current is modified by temperature sensors inside and outside the vehicle and by a temperature selector. The air pressure into the system from the ram effect, when the vehicle is moving, is monitored by a sensor which reduces the motor current accordingly. If the motor current drops below a set value w.r.t. the set conditions, the motor trips out and is reset when the ignition is switched off, or if the fan speed selector is turned down. An override circuit allows the motor to run at maximum for a set period after the ignition is switched on, to clear the windscreen.

Title: DC voltage converter with chopper and positive feedback - allows output to be held constant independent of input voltage variations
Inventor: MIEDEL LOTHAR
IPC: H02M3/338
Filed: 1974-03-07
Abstract: The d.c. voltage converter has an output voltage that follows variations in the input voltage but can also be held constant independent of input variations. The chopper contains a transistor coupled over an output transformer positive feedback winding to a control circuit. A variable resistance is connected between the transistor and the positive feedback winding and has its resistance determined by an actual-value winding belonging to the output transformer.
