Patent DE-2428681-A1 (DE)
Title: DC motor speed control using tachogenerator - is fitted with circuit to compensate for speed signal failure
Inventor: SCHMIECHEN ARMIN
IPC: H02P7/293
Filed: 1974-06-14
Abstract: The object is to compensate for an interruption in, or failure of, the speed signal in such a way that a motor overspeed is avoided. The tachogenerator (G) driven by the motor is connected via two leads (1, 2) to the speed controlling circuitry (3) which has a high input impedance. A stabilized voltage source (E) is connected across the tachogenerator with an ohmic value resistor (4) in series. As long as the tachogenerator circuit is complete the proportion of the voltage (E) dropped across it is small since the circuit is of low impedance. If the circuit is broken the resistor (4) is in series with the controller (3) input and a large voltage appears across the input in consequence thus reducing the motor speed virtually to zero.

Title: Telephone network subscriber identification test system - uses polarised relay which is operated by exchange command signal
IPC: H04Q3/54
Filed: 1975-09-16
Abstract: The telephone network identification and test system consists of a number of subscriber equipments with their respective connection circuits. Each is connected to a coupling field, regional control and identifier unit. Operation of a subscriber apparatus causes an identification signal to be sent to the identifier unit which determines the coupling field connection position for that respective subscriber. This information is passed to the regional control. At the end of this sequence, a polarised isolating relay is operated. The normally-closed contacts (r1-r2) are connected across a detector circuit. To test the identification circuit, a signal is sent from the central exchange through the control to the respective connection unit.
