Title: Network with one central and many mobile stations - has operating radio sender of a mobile station which is periodically switched off
Inventor: JEROMIN JENS-PETER
IPC: H04W52/02
Filed: 1974-01-03
Abstract: A mobile station receiver is switched on, and this state continue so long as it receives a transmission from the central station H.F. carrier, and finalises when the mobile station selective call evaluator receives the corresponding selective call. The selective call evaluating device switches off the sender current by means of a bistable relay. The mobile station bistable relay is tripped back to its initial state, in which the sender is supplied, when the central station transmits a call signal differing from the mobile station selective call by at least one digit. For example 1-4-0-1-7 might be a calling sequence for the mobile station to receive, and 0-4-0-1-7 might be the sequence to switch it off-line.

Title: Short-circuit no-load monitor for AC generator stator winding - has relay preventing generator de-excitation when loaded
Inventor: DROSTE WERNER DR ING
IPC: H02H7/06
Filed: 1974-01-11
Abstract: The short-circuit monitor, for an a.c. generator stator winding, de-excites the generator in its no-load condition when a short circuit occurs between its windings, but blocks this de-excitation process with relays when the generator is loaded. The star-coupled windings each have a monitoring coil coupled via transformers to three rectifiers. The rectifier outputs are combined and passed over the blocking relay contacts to the trigger that operates the de-excitation circuitry when a short occurs with the windings on no-load. The blocking relay contacts open when the generator is loaded (i.e. not protected against shorting) and closed when unloaded (i.e. protected against shorting).
