Patent DE-3730399-A1 (DE)
Title: Method and device for transmitting a digital signal
Inventor: WITTNEBEN ARMIN
IPC: H04B1/62
Filed: 1987-09-10
Abstract: In a transmitter, a digital base-band signal drives a frequency modulator via a pulse-expanding filter. In the receiver, the received signals are fed via a bandpass filter to a frequency discriminator for demodulation. The demodulated signal is filtered in a low-pass filter and passes through a pulse-compressing filter before threshold decoding. A plurality of identical receivers can be connected in such a manner that the bandwidth of the bandpass filter becomes smaller and smaller in successive branches. The pulse-expanding filter has a constant frequency response amplitude and a linearly rising group delay time, while the pulse-compressing filter has a frequency response which is the conjugate-complex of the said filter.

Title: Process and circuit arrangement for picture data reduction for digital television signals
Inventor: STROBACH PETER DR ING
IPC: H04N19/96
Filed: 1987-09-30
Abstract: A process for picture data reduction for digital television signals, a subtraction being carried out in a preprocessing operation to establish the difference between a signal which was generated at an instant t-1 and stored in a picture memory and a signal which is produced at an instant t, so that by this preprocessing a picture-to-picture prediction error signal is formed, the picture-to-picture prediction error signal thus formed having to be coded in the form of an error picture for its transmission. The picture-to-picture prediction error signal is coded without further preprocessing by breaking down into blocks of variable size, which can be written to by a so-called Quadrtree data structure, for which purpose the picture-to-picture prediction error signal is represented in each case in each of the blocks of variable size by its average luminance value and the size of the blocks being varied in such a way that, starting from a basic block of the size m.n picture elements (pixels), they are subdivided as need be in such a way that four sub-blocks of the size m/2.n/2 are produced, which sub-blocks (I, II, III, IV) are in turn subdivided as need be in the same manner into a further four sub-blocks of the size m/4.n/4 and so on. <IMAGE>

Abstract: A device for measuring the liquid level in containers, especially the oil level in internal combustion engines of motor vehicles, has a temperature-dependent resistance element which is arranged in a container in such a way that it spans the range of the possible level fluctuations, and a comparator which measures the voltage drop across the resistive element. In order to reduce the calibration cost and to obtain a continuous measurement of the liquid level which is done as reliably as possible, a second temperature-dependent resistance element provided, which is arranged in the liquid container in such a way, that it spans the range of the possible level variations and may be continuously loaded with current via a second resistor. Furthermore, the comparator compares the voltage drop across the second resistance element with the voltage drop across the first resistance element.

Filed: 1987-12-18
Abstract: Modern telephone sets exhibit supplementary circuits (ZS) such as hands-free talking, display and so forth, which are connected in parallel with a speech circuit (SP) and a transmit amplifier (SV). To be able to provide, on the one hand, a large proportion of a current made available via a telephone line (FL) to the transmit amplifier (SV) (high transmitting power) and, on the other hand, the greatest proportion of the current also to the supplementary circuits (ZS), the speech circuit (SP) and the transmit amplifier (SV) are connected in series between a first wire (La) and a second wire (Lb) of the telephone line (FL). A power-feeding circuit (S) is connected in parallel with the speech circuit (SP) with a first terminal (A1) and a second terminal (A2), a third terminal (A3) of the power-feeding circuit (S) being connected to the second terminal (A2) via the supplementary circuits (ZS). Between the first and second terminal, a voltage regulating circuit (SR) is connected which drives a voltage-control current source (SQ) of the power-feeding circuit (S) in dependence on a nominal voltage allocated to the speech circuit (SP), the third terminal (A3) forming the output of the current source (SQ). <IMAGE>

Title: Method for drawing a cable into a cable duct system, and a device for winding up a cable
Inventor: POREMBA JOHANNES DIPL ING
IPC: B65H75/36
Filed: 1989-01-16
Abstract: When laying long cables which are intended to be drawn into empty tubes of a cable duct system from an interruption point in the cable duct system, originating in two directions, the problem exists that a long piece of cable must be unwound from a cable drum and must be intermediately stored in order to have the second cable end available. For intermediate storage of a residual piece of cable (6), the invention proposes a winding-up device (7) by means of which the cable (6) can be wound up in figure of eight loops (15).

Title: Cleaning surface water - where rain-water etc. is cleaned in system consisting of sedimentation stage, sepn. of floating matter and biological filtration
IPC: B01D21/00
Filed: 1989-06-09
Abstract: The flow velocity of the water is first reduced, floating impurities are removed from its surface and it is subjected to a biological cleaning process before being allowed to soak into the ground. Removal of floating impurities may take place during or after the velocity redn.  stage, and biological cleaning may be combined with this first treatment stage. The water is accumulated to a certain surface level during the treatment before being allowed flow to waste. The system comprises a tapering inlet channel, a sedimentation and accumulation tank, a floating material separator and a biological filter tank from which the water flows to waste. The separator is installed in one of the pipelines leading from the sedimentation tank to the biological filter tank, and the amt. of water flowing to it is controlled by a flow device. The filter tank is filled with a granular material such as gravel, and is at least partially planted with plants. The floor of this tank is at a lower elevation than the floor of the outlet drainage channel, and its upper edge is above the normal water level in this channel. USE/ADVANTAGE - Used where cleaning of accumulated rainwater, melted snow, etc. from surface drains is required before allowing it to be disposed of. The return of the water to seas or lakes or the ground water table without contamination is made possible, and the proposed system is effective and economic and operates independently and without the need for energy input for pumping, etc.
