Title: Turn indicator control circuit for vehicle - employs electronic processor to determine whether short item or continuous signal is selected
Inventor: SCHRUMPF HANS
IPC: B60Q1/40
Filed: 1979-07-06
Abstract: The application is to turn indicator circuits allowing selection of a short time duration signal for overtaking, or a long duration signal signifying a turn. The latter signal is cancelled by a switch operated by turning the steering sheel through a defined angle. The proposed circuit modifications reduces to three the number of leads required between the direction selector switch and the flasher circuit. The flasher unit is controlled by an electronic logic circuit. This receives two signals from the selector switch on the steering column which indicates direction and whether a continuous signal is required. One lead is needed for each direction, and one for ordering continuous signalling for a turn. The electronic logic evaluates the incoming signals and operates the flasher unit accordingly.

Title: Calibration test circuit for optical measurement instruments - has generator supplying phased signals and averaging circuit
Inventor: KRAUSE GERHARD
IPC: G01N21/27
Filed: 1979-11-02
Abstract: A circuit for automatically testing the calibration of optical measurement instruments, esp. analysis instruments, measures the attenuation of light passing along a measurement path to a photoreceiver with an electronic evaluation circuit determining the reduction in the measurement signal. The automatic test procedure is simplified and its accuracy improved. The attenuation is a result of a defined reduction of the electrical parameter influencing the indication signal which is split up into pulses for the averaged reduction. An averaging stage connected in front of the indicator has a time constant greater than the pulse interval. The lamp voltage, modulator control voltage or photoreceiver output signal may be converted into pulsed form using a test signal generator.

Title: Plastics clamping device - with piezoelectric scanner for temp. compensation of clamping pressure
Inventor: BILDNER CAROLYN
IPC: A63C9/08
Filed: 1980-01-23
Abstract: A clamping device to secure elastically deformable materials such as plastics, for example in milling machine tools, is an integration of a physical scanner with an electronic display. Piezoelectric elements are built in to monitor the clamping pressure. If a rising temperature raises the clamping pressure, the adjustment of the clamp relative to the stationary part effects a longer distance until an optical indicator indicates equilibrium. The distance is shortened in case of a temperature drop. This eliminates damage by excess pressure or slackness by loss of pressure.
