Title: Protective circuit for electrical appts. - has mechanically actuated switch for holding coil to connect appts. to three=phase mains
Inventor: RATHJENS WOLFGANG ING GRAD
IPC: H01H3/50
Filed: 1977-07-21
Abstract: A switch (13) in the circuit of a coil (12) is mechanically coupled to the safety contacts (11) by which a consumer apparatus (10) is connected to the three-phase mains. Hence the coil is energised only when the contacts have been closed, so that the coil needs to accept only a holding voltage, the pull-on energy for the switch (13) being applied mechanically. The coil therefore needs to be designed only for the holding voltage. The coil is connected between two-phases of the three-phase mains and includes a cut-out (14) and a thermal relay (15). The arrangement has the advantage of requiring less electrical energy for its operation than known arrangements.

Title: Vehicle mounted acceleration actuated switch - has stem and flat conductive base, tilted by accelerating weights altering capacitative effect
Inventor: BURMESTER RALF
IPC: H01H35/14
Filed: 1979-02-15
Abstract: A rotation symmetrical inertial body is deflectable against a restoring force. The body is coupled to a base surface at right angles to the axis of symmetry and outside the centre of gravity. The restoring force causes this base surface to rest against a supporting surface. The base surface and the conductive supporting surface form the plating of a plate condenser. Its capacity is changed by deflection of the inertial body and this effect is used to control a switching stage. In an embodiment a stem carries a disc at one end which constitutes the base surface. The other end is joined to the accelerating weight. The stem is tiltable and slidable near the disc and is mounted in the opening of a conductive supporting surface.

Title: Accumulator battery charging using wind driven generator - involves adjustment of generator current up to limit charging voltage, using generator frequency and preset frequency dependent function
Inventor: KOETHE HANS-KURT DIPL ING DR
IPC: H02J7/14
Filed: 1979-12-15
Abstract: The charging generator has a constant excitation field and a variable drive speed. Until the generator current has attained a limit charging voltage, it is controlled by a setting element (6) in response to the generator frequency preset function in such manner that for each drive speed the maximum generator output is adjusted. The generator output is supplied to the charged accumulator (11) via the setting element, minus a negligible magnitude. Preferably the generator current (I,G) is adjusted in accordance with the preset function to meet a specified exponential function whose power factor is between 0.25 to 1. On reaching the limit charge voltage a part of the tapped generator output may be converted into heat. The setting element is typically incorporated between the generator (3) and the accumulator, the setting element being connected to the control output of a regulator (9), whose input receives a generator frequency dependent signal.
