Patent DE-3310242-A1 (DE)
Title: Circuit arrangement for surge-voltage protection, with an automatic reset
Inventor: GRUENSCH ECKHARDT
IPC: H02H9/04
Filed: 1983-03-22
Abstract: The invention relates to a circuit arrangement for automatic resetting of a surge-voltage protection device once it has tripped and is characterised in that a two-pole network, assuming two resistance values, is connected in parallel with the surge-voltage protection device, which two-pole network has such a low resistance after triggering of the surge-voltage protection device that the current through the latter falls below the value of its short-circuit latching current so that the surge-voltage protection device is extinguished, and in that, subsequently, the two-pole network is changed back to its high-resistance state. As a result of this uncomplicated arrangement, which just has to be connected in parallel in a simple manner, the blocking of a surge-voltage protection device is automatically cancelled, as a result of which long failures of unmanned stations, especially after thunderstorms and switching processes can be avoided.

Title: Supply lead for electrical apparatuses
Inventor: WANNER KARL DR
IPC: H01R13/639
Filed: 1983-11-30
Abstract: A supply lead for electrical apparatuses consisting of at least two cables (2, 3) and a plug coupling (4) is proposed, whose plug coupling is relieved of tension by means of a cable loop. The supply lead (1) itself carries a holder for fixing the cable loop. Said holder therefore does not need to be provided on the electrical apparatus or its handle itself. Plug couplings (4) which are remote from the apparatus can thus also be relieved of tension by means of a cable loop. A plug (5) having a sleeve (9) which is at the same time a handle and has a holder (7) with hooks (8) causes scarcely any added costs in manufacture. The handling of the holder (7) is so easily understood that it does not need to be especially explained. Holders (10, 11, 12) which are designed as loose components and are supported by the supply lead (1) are also specified. <IMAGE>

Title: Adjusting device for parts of pneumatic tube conveyor systems
Inventor: BLESSING ALBERT
IPC: B65G51/36
Filed: 1984-10-23
Abstract: An adjusting device for parts of pneumatic tube conveyor systems which can reciprocate between mechanically fixed end positions contains an electric motor which can reverse its direction of rotation. A switching device which is controlled by the control device of the pneumatic tube conveyor system is situated in the circuit of the electric motor, the electric motor being supplied with current in accordance with the desired direction of rotation via the switching means of the said switching device, and the switching device switching off the motor current when the respective end position has been reached. The electric motor can then only be restarted with rotation in the opposite direction. In order to dispense with end position switches which are to be actuated by the part, the current consumption of the electric motor depends on the actuation. A current sensor is situated in the circuit of the electric motor, the outlet of which sensor is connected to a threshold value switch, which controls the switching means situated in the circuit at their control inlet in such a way that when the threshold value is exceeded, the current, associated with the corresponding direction of rotation, for the electric motor is disconnected and also remains disconnected until the motor is restarted with a different direction of rotation.
