Title: Motor vehicle windscreen wiper circuit - uses Schmitt trigger output to control auxiliary switching transistor base with input set by dry-wiper key switch
Inventor: BERGMANN EDUARD
IPC: B60S1/08
Filed: 1978-12-15
Abstract: The electrical switching circuit in direct current network for a motor-driven vehicle is used to operate the windscreen-wipers during a stalling interval and a dry screen delay. The wiper motor with a pre-selected holding position-switch is controlled by closing the 'interval' switch or operating the drying-action switch. The output of a Schmitt trigger controls the base of an auxiliary transistor - acting as a switch - which has an inductive load, ie. relay. The emitter path is set at a supply voltage via the relay and the collector at a reference voltage. The input is controlled via a dry wiping-key-switch, time-gating circuitry ie. a RC - stage and a diode. The Schmitt trigger, is set a zero potential at the output and the transistor conducts, when an upper threshold value of 2/3 UB is attained at the input. The transistor during discharge of the capacitor via a resistor - at the reference potential - between the RC - stage and diode is parallel switched via a series network of resistances and diodes when the lower threshold value of 1/3 UB of the Schmitt trigger is attained.

Title: Test facility for use in digital data exchange - uses PCM test word which is fed from common control during routing to test call stores
Inventor: RAMBOLD THOMAS DIPL ING
IPC: H04M3/24
Filed: 1979-02-13
Abstract: The method is for testing the speech memory stores of a PCM TDM exchange. The stores are located in the various TDM switching highways and are used for both writing in and reading out of the signals passing through the exchange. The PCM test word is read into each store in the exchange time frame scan rotation and, after being held in the store, is read out of the store on the scanning cycle for comparison with the original test word. The test word originates from the exchange common control and is read in during the call set up period. It plays no part in routing the call but is used to prove the switching modules as the call is routed through the various modules of the exchange. The latter comprises two common control units (MP1, MP2) routing calls from the incoming lines (ZL) through the exchange switch blocks (MTSO-3). The common controls (MP1, MP2) are connected through multiplexers (MPMO, MPM1, MPM2, MPM3) to the switch block to achieve maximum diversity and security. The stores under test are located in the switch blocks (MTSO-3).
