Title: D=A converter using two conversion laws - has digital input applied to converter through modulator with inversion technique for digital bits in second law case
Inventor: WINTZER KLAUS
IPC: H03M1/00
Filed: 1978-09-28
Abstract: The digital/analog converter is designed to operate using both the A-law and the u-law.

Title: Pushbutton circuit for vehicle electric devices - has pushbuttons divided into groups, each forming voltage divider with series connected resistor actuated by own transistor
Inventor: WESEMEYER JUERGEN DIPL ING
IPC: B60R16/03
Filed: 1978-12-29
Abstract: The push-button circuit consists of push-buttons coupled in parallel, via staged resistors in series, to form a group which is connected via transistor (28, 29) to a shared resistor (22). This forms a voltage divider connected to the supply. The divider tapping produces a signal voltage. The switching states of the push-buttons are interrogated by a microprocessor, using clock pulses at the control input of the transistor. The signal voltage at the divider tapping is also measured. The signal volrage is fed to the microprocessor which then initiates the appropriate switching step via a decoder(25). The switching paths of the push-button groups preferably lie at the divider tap via a transistor switching path behind the common resistor. The decoder may contain cyclically energised amplifier stages (33, 34), with outputs coupled each to a transistor control path.

Title: Determining exact position of hydraulic cylinder piston - using metal or gas spring in cylinder and couterpressure measurement
Inventor: HANNES HEINZ DIETER
IPC: F15B15/28
Filed: 1979-07-03
Abstract: The method and device for determining the exact position of a hydraulic cylinder piston to operate under external ambient conditions, esp. high temp., are applicable to the adjustment of foundry ladle sliders where high positioning accuracy is required.

Patent DE-2939234-A1 (DE)
Inventor: WEIGERT KURT ING GRAD
IPC: A61B5/05
Filed: 1979-09-27
Abstract: Current stimulation apparatus, in particular, exhibits an output stage as the current waveform generator for producing an output current through a patient's body as the load resistance. Such apparatus operates with a specifiable operating voltage and controls the patient current in a constant-current fashion in the case of a varying load resistance. Preferably, the patient current is here measured through determination of the voltage across defined resistance terminals, whereby magnitude as well as peak values can be displayed on the display units associated with the output stage. Up to the present time, the measuring and display units had been fed by power supply units which deliver a supply voltage in relation to operating potential. According to the disclosure, all units for measuring, further processing, and/or display of the patient current are decoupled from the operating voltage circuit and receive supply voltages which are directly defined in relation to ground potential.
