Patent DE-3115497-A1 (DE)
Inventor: SCHMITT WALTER ING GRAD
IPC: G01P13/04
Filed: 1981-04-16
Abstract: A frequency-to-voltage converter for a digital tachometer is disclosed which is responsive to two measured signals generated by a rotational transducer. These two measured signals are applied to a direction discriminator which generates multiple pulse trains in response to the transducer. Each of these pulse trains has a frequency no less than that of the measured signals and the pulse trains are offset with respect to one another in phase angle. Each of the pulse trains is applied to a separate switching circuit which acts to generate a respective sequence of constant energy pulses. These sequences of constant energy pulses are summed in a summation amplifier and passed via a low pass filter to one input of a differential amplifier. The other input of the differential amplifier is coupled to the direction discriminator by a similar sequence of switching circuits, a summation amplifier, and a low pass filter. The output signal of the differential amplifier is proportional to the rotational velocity sensed by the transducer.

Title: Light circuit for interruption-sensitive high-pressure lamps
Inventor: LOEF CARL DIPL ING
IPC: H05B41/46
Filed: 1981-04-29
Abstract: A circuit for high-pressure lamps, in the case of which, when the mains power supply voltage is present but has briefly been interrupted, incandescent lamps or low-pressure gas-discharge lamps produce sufficient light during the lamp cooling time. A circuit of this type having incandescent lamps is known, but not for high-pressure lamps with an increased starting voltage, and likewise not in conjunction with low-pressure gas-discharge lamps. In the case of the invention, a series circuit (which is located between the lamp output of the high-pressure lamp ballast unit and the opposite phase or neutral conductor) of specific inductance (L2 inductor coil), capacitance (C2) and an incandescent lamp (G1) locks the passage of the high-frequency starting voltage so that there is no adverse effect on the starting process. At normal mains frequency and when the high-pressure lamp has failed, (L2) and (C2) raise themselves with respect to one another and the incandescent lamp (G1) burns brightly (Figure 1). In a further version using low-pressure gas-discharge lamps (LL), these lamps start and burn only when the high-pressure lamp has failed and the voltage ULL is thus high enough (Figure 2). <IMAGE>
