Title: Vehicle spray gun motor speed control device - utilises optical head assembly to detect rotational speed of patterned disc
Inventor: FLEIG GUNTHER
IPC: B05B5/04
Filed: 1980-01-22
Abstract: The speed of a fluid motor is controlled by an optical feedback system to control a spray gun for the final coating on a motor vehicle. The speed takes account of the coating characteristics and the variable loading effects. The fluid motor comprises an output shaft on which an atomiser is mounted. A supply tube provides the coating material from one of several sources via contr controls and is sprayed onto an object which is at an electrostatic potential. An optical head assembly contains an optical fibre to conduct light from a source. An optical receiver mounted within the motor casing provides a signal reflected from a pattern on a disc on the motor shaft. Electronic circuits respond to the received light to compare rotational speed with a time base to provide a speed control signal for the motor.

Patent DE-3014214-A1 (DE)
Title: Digital signal transmission system - uses opto-electronic couplers controlling FETs transistors to increase transmitted signal frequency and gain
Inventor: KUNERT REIMAR ING GRAD
IPC: H04B10/80
Filed: 1980-04-14
Abstract: The appts. is used to give a required increase in switching precision and speed leading to an increase in transmission frequency which is achieved by adding a field effect transistor to the opto-transistor part of the opto-electronic coupler. The source and drain electrodes of the FET (8) are connected to the two lines (1,2) of the transmission link together with a low ohmic value resistor (9) between one line (2) and the source electrode. The FET gate is connected to the collector of the transistor (7) on the transmission side of the opto-electronic coupler (3). The conducting, or non-conducting state of the opto-transistor is reflected inversely in the FET. When illuminated, the transistor is maintained at, or just below, saturation limit by a diode (13) connected between the base and the low ohmic value resistor (9). A similar arrangement applies to the receiver (4,27) to regulate saturation. The FET works as a switch. With no illumination the switch is closed, with illumination open. The current drain of the phototransistor when conducting is materially lower than the flow through the FET when the latter conducts. The rapid switching capability, and the high gain change due to avoidance of saturation gives the required high frequency operation.

Title: Integrated telephone handset amplifier testing circuit - samples output amplitude and verifies occurrence of given measuring ratio within defined interval
Inventor: HEIDEL GERT
IPC: G01R27/28
Filed: 1980-05-31
Abstract: The testing circuit verifying the required amplifications or alternation ratio uses a test voltage (Pu) with a given frequency and amplitude to obtain a pair of control pulses (PT,ST) respectively fed to two evaluation devices (PB,ZB). The first of these samples the amplitude of the output voltage (PE) of the amplifier (pr) and the supplied control pulses (PT) are phase offset by 90 degrees relative to the test voltage (Pu). The other evaluation device (ZB) has a counter receiving the other control pulses (ST) and halted when a given measuring ratio appears at the output of the amplitude evaluation device (PB). The counter is combined with a comparator (GVE) and a store (FZ) to provide an output indicating if the measuring ratio has occurred within a time interval defined by max. and min. time values. The testing cycle is quick to carry out and provides a direct acceptable/ inacceptable read-out.
