Title: Method for detecting and processing a pilot signal
Inventor: PLEIER GERHARD DIPL ING
IPC: H04N7/20
Filed: 1981-03-09
Abstract: A method for synchronising the carrier frequency, generated in a down converter (receiver), of a television signal which was transmitted from an up converter (transmitter) via a directional radio link, with the carrier frequency of the original television signal used in the up converter. For this purpose, a pilot signal is added to the television signal in the up converter and also converted into the microwave band. The down converter has a controllable oscillator, with the aid of which the transmitted pilot signal is shifted by being mixed down to a frequency below the useful frequency of the pilot signal, is then filtered out and compared with a frequency signal derived from the controllable oscillator. The difference signal formed from this comparison is used as controlling variable for the control loop of the oscillator of the down converter which corrects the frequency of this oscillator to the mother oscillator in the transmitter. <IMAGE>

Title: Measuring instrument with alternating-current bridge circuit
Inventor: SCHROEDER KURT OSKAR HERMANN P
IPC: G01R17/14
Filed: 1981-04-28
Abstract: In the instrument, the coil of one of two resonant oscillatory circuits (I, II) takes the form of an air-cored inductor (ML1) with a free passage so that a substance having ferromagnetic properties, for example metallically contaminated lubricating oil can be passed through it. The disturbance of the bridge equilibrium thereby produced can be tapped off from the zero-indicating galvanometer circuit (III) as a change in alternating voltage which is equivalent to the required magnitude of the ferromagnetic contamination. To measure those properties of a substance which are dependent of the permittivity, the capacitor of one of the resonant oscillatory circuits takes the form of a plate capacitor (MG1) so that the test substance can be introduced between the capacitor plates, thereby also measurably disturbing the bridge equilibrium. The zero-indicating galvanometer circuit (III) is also expediently a resonant oscillatory circuit tuned to the generator frequency. <IMAGE>

Patent DE-3128577-A1 (DE)
Title: Circuit arrangement for limiting the transmission power of an inductive transformer
Inventor: KRAUSE DIETER DR DIPL ING
IPC: H02H9/00
Filed: 1981-07-20
Abstract: In the case of an inductive transformer having a laminated core and a DC-decoupled input and output, the input variable is modulated with the aid of a reversible clock-frequency generator. A first clock frequency, the operating frequency, is less than the eddy-current limiting frequency of the laminated core, and a second clock frequency is greater than said limiting frequency. The clock frequency is switched over by the output signal of a monitoring circuit in which a voltage which is proportional to the input variable is compared with a voltage which corresponds to a limit value. This limit value is determined by the maximum permissible transmission power of the transformer. The circuit arrangement is thus used for limiting the transmission power and its main use is in isolating transformers between circuits which are not explosionproof and circuits which are explosionproof.
