Patent DE-3415474-A1 (DE)
Title: Analog control loop and its use in a pulsed radar system
Inventor: FALSCHEBNER ROLF DIPL ING
IPC: G01S7/40
Filed: 1984-04-26
Abstract: An analog control loop, the actual value of which is only briefly available within one period, operates with a clocked control system which stores a manipulated variable and corrects it by a correction value derived from an error value. Limiting the correction value reduces the susceptibility of the control loop to noise pulses. The control loop is particularly advantageously used in a pulsed radar system for calibrating the system during the dead time.

Title: Method for identifying users of a telephone set
Inventor: HUTT HANS
IPC: H04M1/54
Filed: 1984-05-18
Abstract: In the method for identifying users of a telephone set, the telephone contains a coding device which is activated with a key which is handed over to the user and which, once the telephone handset is lifted, generates a specific user identification signal dependent on the coding of the key. This user identification signal is transmitted via the connection line to the telephone switching system to be stored along with the data of the respective call connection. It is thus possible, for example, for personalised central call data acquisition to be carried out with the result that a plurality of persons using a telephone set can be accurately distinguished from one another.

Title: Method and circuit arrangement for digitally differentiating between SECAM, PAL and monochrome signals
Inventor: SCHMELOVSKY KARL-HEINZ PROF DR
IPC: H04N9/64
Filed: 1984-09-03
Abstract: When the invention is used in multi-standard colour-television receivers, it is intended to reach a decision, using predominantly digital means, between the three following types of received signal, SECAM, PAL, and monochrome, the probability of incorrect decisions being reduced and, in addition, it being intended to produce the signal for synchronisation of the line-frequency switch. Using the digital variable ZÄ for the offset of the instantaneous frequency of the SECAM signal, and using a second digital variable SIGMA  +/- for the phase shift of the PAL colour burst, which is obtained either in an analog or digital manner, a parameter is obtained by addition with alternating mathematical sign, the magnitude and mathematical sign of which parameter indicate which standard was present in the preceding field and whether the line-frequency switch is correctly synchronised. According to the invention, the result of the magnitude test is used for controlling a state register. The position of this state register supplies on the one hand a selection signal which determines which of the two standards is tested. On the other hand, by decoding the position of the state register, in each case one signal can be obtained for driving the colour killer and for selecting the corresponding colour demodulator.

Title: Device for controlling a cooling air flap
Inventor: RAFFNSOEE-DALL BENT DIPL ING
IPC: F01P1/00
Filed: 1984-09-28
Abstract: The invention relates to a device for controlling at least one cooling air flap in a wall adjacent to an internal combustion engine, especially on the radiator grille of a motor vehicle, the flap being actuated as a function of the temperature and speed in such a way that it is constantly closed below a first threshold temperature T1 of the internal combustion engine and opened above T1 but below a predetermined threshold speed of the motor vehicle, and closed above this threshold speed. Above a second predetermined threshold temperature T2 of the internal combustion engine, the cooling air flap may be constantly opened. By means of these measures, any heat build-up in the engine compartment is reliably prevented, whilst maintaining a favourable coefficient of air resistance and possibly a low noise emission of the internal combustion engine. <IMAGE>
