Patent DE-2339365-A1 (DE)
Title: Steering column switch for windscreen washer and wiper - has two self cancelling positions controlled by sprung tongue of contacts
Inventor: ERDELITSCH HERBERT
IPC: B60Q1/14
Filed: 1973-08-03
Abstract: The switch lever is pivoted to a horizontal pivot pin in the switch housing fixture and presses against a projection on a sprung tongue which carries a contact bridge in one position, and a second contact at its extreme end. The sprung tongue is a separate part which locks in an opening in the switch fixture. The tongue projection is provided with a recess into which a finger extending from the switch lever is fitted, the tongue is first depressed until contact is made with the extreme end contacts. In order to complete the second circuit, the resistance offered by the stop finger must be overcome when the bridge completes the second circuit by joining the contacts.

Patent DE-2409636-A1 (DE)
Title: Cable clamp which locks under load application - has diagonally moving block inside clamp bracket
Inventor: STAFFORD LAWRENCE RALPH
IPC: F16G11/04
Filed: 1974-02-28
Abstract: A clamp which is used to attach a load to a rope or cable is self locking when the load is applied to a lever. The lever which is located on a pivot is placed in a slotted wedge piece. A U-shaped bracket encloses the wedge block so that the rope is clamped between the two components. When the lever end is loaded, the other end rests against a transverse inclined plate, thus pulling the clamp block downwards and against the clamping bracket. The clamping force is thus proportional to the load carried by the clamp. When the load is removed a tension spring resets the lever so that the clamp is free.

Title: Control system for motor - has sensor controlling stator supply and containing core driven in and out of saturation during rotation
Inventor: WARREN ANTHONY CHARLES
IPC: H02K29/12
Filed: 1974-03-07
Abstract: The control system for an electric motor has a sensor to control current supply to the stator. The sensor contains a saturatable magnetic core forming a pole face next to the rotor pole face. The magnetic core is exposed to a pre-magnetising field of such a magnitude that when the rotor rotates about its axis the core is driven in and out of saturation. The pre-magnetising or background field is produced by a permanent magnet or by an electromagnet. A coil wound around the core provides the output that determines the stator supply regulation.

Title: Safety insert for pneumatic type - with trapezoidal internal tyre to hold outer tyre on wheel rim
Inventor: WITTNEBEN HERMANN DIPL ING
IPC: B60C17/01
Filed: 1974-06-12
Abstract: The pneumatic tyre (5) has a tubeless structure and is fitted onto a conventional wheel rim (2).

Title: Coaxial valve actuating mechanism - has diaphragms moving in opposite directions at right angles to valve spindle
Inventor: FEINAUER WERNER
IPC: F16K31/165
Filed: 1974-12-10
Abstract: The mechanism has two coaxial diaphragms working against spring action, and whose movement, resulting from application of pressure, shifts the valve spindle in the opening direction. The diaphragms (2, 3) move in opposite directions, and a act on a drive mechanism (17) between them coupled to the spindle (23), which is at right angles to their direction of movement. The drive mechanism can incorporate a gearwheel, meshing with a rack on the valve spindle and other racks coupled to the diaphragms. Alternatively a crank drive mechanism can be used, the two bearing of the connecting rod to the valve spindle being so positioned that they are in line with it in the shut position.

Title: Squirrel-cage rotor async. motor - has massive low-carbon iron rotor with circular and straight slots filled with copper
Inventor: KAMMERLING WALTER
IPC: H02K17/16
Filed: 1974-12-19
Abstract: The squirrel-cage asynchronous motor has a rotor consisting of a massive shaft of iron with a very low carbon content. The squirrel cage is formed by copper filled slots, in the surface of the shaft. The slots consist of axially parallel lengths and circular parts. The copper can be replaced by aluminium or any other good metal of good conductivity. The light construction of the cage reduces the effects of centrifugal force and improves the motor characteristics at high speeds. The copper may be deposited into the slots by casting, injection, brazing, welding or electrolytic deposition. The rotor may form a part of the motor shaft.
