Patent DE-3136989-A1 (DE)
Title: Measuring device in an internal combustion engine
Inventor: WESSEL WOLF ING GRAD
IPC: G01F1/28
Filed: 1981-09-17
Abstract: A measuring device in an internal combustion engine is proposed for the flow rate, related to a stroke, with a flap-type flow meter whose flap deflection determines the position of a potentiometer (15), the supply voltage of the potentiometer being dependent on the speed of rotation. In this way, an output signal of the flow meter is obtained which is inversely proportional to the stroke-related flow and the flow meter is suitable both for detecting the load of the internal combustion engine and, in conjunction with the measurement, the rate of exhaust gas feedback. <IMAGE>
Patent DE-3140342-A1 (DE)
Title: Device for separation of liquids in piping for gaseous media
Inventor: KALTENTHALER WOLFGANG ING GRAD
IPC: F16L55/09
Filed: 1981-10-10
Abstract: In closed piping for gaseous media, which for example contain a compressor, small amounts of oil from the lubrication system of the compressor occasionally penetrate into the unit. To remove these oil constituents, a separating device is arranged in the pipe system of the unit, which according to the invention is based on the observation that oil constituents or other liquid constituents creep along the walls of the tubes. The separating device is designed in such a manner that the liquid constituents creeping along the walls are trapped and are passed into a container (oil sump of the compressor). This device can also be used for the removal of liquid refrigerants in refrigeration units.

Title: Process for regulating the rich gas heating of coke ovens
Inventor: STRUCK CARL-HEINZ DIPL CHEM
IPC: C10B21/10
Filed: 1981-11-06
Abstract: In a process for regulating the flame length and for optimising the vertical temperature distribution in coke oven heating flues heated by rich gas, to which rich gas is fed via lines which run from the nozzle basement of the oven battery through the particular regenerator partition above and end in a burner head which is located in the lower section of the heating flue, while the combustion air heated in the regenerators enters through orifices at the bottom of the heating flue, a gas of low calorific value, which can be blast furnace top gas, generator gas or reaction gas from a direct-reduction reactor, is fed to the individual heating flues in the immediate vicinity of the end of the burner head. The gas of low calorific value can wholly or partially consist of combustion exit gases. The feeding of the gas of low calorific value is appropriately effected via an annular space surrounding the end of the burner head.
Patent DE-3147364-A1 (DE)
Title: Circuit arrangement for an audible signal generator
Inventor: FRYSTACKI HENRYK DIPL ING
IPC: B06B1/02
Filed: 1981-11-30
Abstract: The amplitude of the signal voltage of a clock generator is modulated in order to generate a ringing signal. It receives an envelope which is characterised by a steep leading edge and a gently falling trailing edge. The modulator is an operational amplifier (OP) (Fig. 2), at whose inverting input the signal voltage of the clock generator (TG) is continuously present, and whose non-inverting input is connected to ground via a resistor (R4) and a capacitor (C1) connected in parallel. The amplification of the operational amplifier (OP) is selected in such a way that, even when the signal voltage is present, the output remains at zero saturation. If the capacitor (C1) is charged by a pulse generator (IG) via a diode (D), the output of the operational amplifier transmits the amplitude-modulated signal voltage to the audible signal generator. <IMAGE>

Patent DE-3203800-A1 (DE)
Title: Illuminating device of a test projector for colour television cameras
Inventor: BREI VACLAV
IPC: H04N17/02
Filed: 1982-02-04
Abstract: The illuminating device consists of a light source, a device for homogenising the light density of this light source, a device for controlling light intensity, and a device for setting various light colours in the illuminating device. It ensures a high degree of homogeneity and stability, both in colour and in level, even under extreme environmental conditions. The illuminating device is very simple, compact and of light weight so that it can be accommodated in a very small space. With a constant aperture of the projection lens and the colour of the light remaining the same, the intensity of illumination at the image pick-up tubes can be continuously controlled in the range from zero to approximately 100 lux and the power consumption of the light source can be clearly below 10 W.

Patent DE-3204827-A1 (DE)
Title: Sidetone-free radio monitoring installation
Inventor: MENNING HERMANN DIPL ING
IPC: G08B13/16
Filed: 1982-02-11
Abstract: The receiver evaluates the incoming modulation voltage which controls the activation of the loudspeaker. Two fundamental options can be employed here:   1.) Continuous modulation of the transmitter by the microphone voltage only; recognition of relevant signals in the receiver through complex signal analysis or activation of the loudspeaker as from a predefined demodulated AF voltage. 2.) In addition to the continuous modulation of the transmitter by the microphone, modulation with a code signal as soon as a relevant microphone voltage is recognised in the transmitter. This defined code signal is decoded in the receiver and leads to activation of the loudspeaker. r
