Title: Circuit arrangement for boosting low audio frequencies of a sound reproduction
Inventor: BARTHELT HANS-PETER DIPL PHYS
IPC: H03G9/14
Filed: 1985-01-31
Abstract: In the circuit arrangement for boosting low audio frequencies of a sound reproduction, e.g. in the form of a broadcast programme, a tape or cassette playback, the volume control normally provided is bypassed by tapping part of the audio frequency voltage on or upstream of the volume control, forwarding it via a chain comprising RC components and a potentiometer and then feeding it back in downstream of the volume control but upstream of an audio-frequency output amplifier, e.g. a broadcast receiver, tape recorder or cassette recorder. In order to prevent a short-circuit of the removed part of the audio frequencies or the part which is to be fed back in, a decoupling resistor is provided in each case between the potentiometer and the output amplifier or between the volume control and the output amplifier. By means of this circuit arrangement, the volume of low frequencies can be set independently of the general volume control due to the fact that the normal volume control is bypassed, the signal level in the diverted part of the audio frequency voltage increasing as the signal audio frequency decreases.

Title: Operational amplifier
Inventor: HOSTICKA BEDRICH
IPC: H03F3/30
Filed: 1985-02-06
Abstract: The invention relates to an operational amplifier with a differential amplifier stage and a current adjusting transistor which is common to both branches of the differential amplifier stage and the control potential of which is generated by an operating- point-adjusting circuit. The invention consists in that the operating-point-adjusting circuit consists of a voltage divider, an amplifier driven by the voltage divider and an invertor forming a control loop with the amplifier. The amplifier output is connected to the control electrode of the current adjusting transistor, and the transistors of the operating-point-adjusting circuit correspond to transistors of the differential amplifier stage to such an extent that the differential amplifier can be optimally modulated at the control potential occurring at the current adjusting transistor. This circuit is suitable, in particular, for MOS-type operational amplifiers with a great spread in threshold voltages of the transistors.

Patent DE-3512370-A1 (DE)
Title: Steam generator
Inventor: EGGERT HERMANN
IPC: D06F75/12
Filed: 1985-04-04
Abstract: For the treatment of textiles with water vapour, for example with a steam iron, the water vapour is not constantly required, and is therefore only to be available precisely when an operation is to be carried out. It has proved advantageous to provide steam generators for this purpose which work according to the so-called injection principle. According to this principle, water is sprayed, if required, via a dosing valve into an evaporator space which immediatley converts the water completely into steam and delivers it to the consumer. It is proposed to design the evaporator space of the steam generator (1) which consists of an evaporator hollow core (4) as a hollow funnel space (21) with a V-shaped cross-section in order thus to obtain a large evaporator surface with minimum overall dimensions and, to guarantee an optimum steam generating capacity, to spray the water from the cavity funnel tip into the hollow funnel space via a spray nozzle (24) which in this case generates a hollow conical spraying jet. <IMAGE>

Patent DE-3529466-A1 (DE)
Inventor: DENZAU HELMUT DIPL PHYS DR RER
IPC: G01V3/08
Filed: 1985-08-16
Abstract: At least one string of several spaced measuring probes for the measurement of surface potentials is laid on the surface of the earth in such a manner that several probes are located outside and several probes are located inside the area of the surface over a reservoir. The potentials measured by all probes are polled in a sequence of periodic cycles. The signals from each probe are, during each cycle, filtered to separate higher-frequency changes in the signals from substantially lower-frequency changes in the signals. For the higher-frequency changes in the signals from each probe, an average and/or a sum are determined as a measure of the higher-frequency amplitudes for each probe. The higher-frequency amplitudes for the probes of a string of measuring probes are compared and the location at which the higher-frequency amplitudes for two adjacent probes change abruptly is taken to be the hydrocarbon/water interface in the underground reservoir.
