Patent DE-4137207-A1 (DE)
Inventor: SOWA WOLFRAM DR
IPC: H05B41/28
Filed: 1991-11-12
Abstract: The invention relates to a circuit arrangement for operating discharge lamps. A high-frequency signal is coupled out of the series-resonant circuit (5) via a coupling element (7) which preferably consists of an RC element, and said high-frequency signal is supplied to the centre tap (M2) between the filter inductors (FD1, FD2) of the high-frequency filter (1). In this case, the technical characteristic data of the coupling element (7) are optimised empirically in such a manner that the high-frequency signal which is fed in at the centre tap (M2) is superimposed on the high-frequency interference voltages in the mains supply leads in antiphase, at the same frequency and approximately at the same amplitude. In consequence, the high-frequency interference voltage level in the mains supply leads can be reduced by approximately 10 dB. <IMAGE>

Patent DE-4201194-A1 (DE)
Inventor: NEUSTADT ALF DIPL ING
IPC: H04B1/10
Filed: 1992-01-18
Abstract: Received TDMA signals can have greatly fluctuating levels section by section. In DC-coupled amplifier circuits, the received signals are falsified by deviations from zero (offset voltages) which occur. Conventional correction or calibration methods use control mechanisms which do not take into account the level fluctuations or an offset drift and easily lead to wrong compensation of individual signal sections. Other methods are dependent on time intervals with known mean value which are defined in the received signal. It is the object of the invention to represent a correction method and circuit arrangement which achieves a self-setting (sliding) correction value which does not greatly fluctuate, whilst at the same time avoiding wrong compensation. This is achieved by the fact that the individual time slots are selected by means of a limit value in a comparator. <IMAGE>

Title: Data reduced speech communication based on non-harmonic constituents - involves analogue=digital converter receiving band limited input signal with digital signal divided into twenty one band passes at specific time
Inventor: KOENIG FLORIAN DIPL ING
IPC: H04K1/00
Filed: 1992-02-06
Abstract: The signal processing stages appertain to a digital input-side, data-reduced speech signal synthetisation, i.e., the prodn. of a bit-data-minimised spectral range information. The band-limited input signal (IN) is fed to an analogue/digital convertor which cuts out on digital signal transmission. The input-side original telephone signal remains spectrum-related in a scanned, complete, non-bandpass-divided version in extent and phase. In this element (2) is simplified the actual digital connection, viz. the input signal spectrum (LE), as a function of the frequency (f) in a transmission range (fU = 300 Hz up to fO = 3.4 kHz). The connecting element (3) in the signal flow plan describes the signal analysis, e.g., fast-Fourier transformation, filtration, etc., or the recognisable alteration in the presentation of the spectrum (L) as a function of frequency (f). The digital signal at a specific time point is divided with its spectrum into 21 bandpasses. ADVANTAGE - For data-reduced speech communication.

IPC: E02D7/14
Filed: 1992-04-03
Abstract: The control unit has an upper position sensor (30), which responds to the reaching of the desired upper end position of the impact wt. (10). An additional lower position sensor (34) responds to lower end position of the wt.. Third and fourth position sensor (32,36) are provided at the same level of the upper and lower sensors (30,34). The output signals of the position sensors which are located at the same (30,32) are fed to the inputs of an OR gate. A control stage (42) of the control unit (28) depends on the output signal from the OR gate. A fault detection circuit is acted on with the output signals of the position sensors (30,32). This then prepares a fault signal, if within a lifting or falling phase or a movement cycle of the wt., an input signal is not received from those position sensors (30,32) located at the same level. ADVANTAGE - Automatic operation is still also possible with failure of one position sensor and indication is given of failure. Repair can follow at next standstill.
