Title: Solar heat collection system - using collector filled with low volatile fluid for expansion in power generating turbine
Inventor: GRAB ROLF
IPC: F03G6/00
Filed: 1978-10-24
Abstract: Solar energy is utilised by solar heat collectors which are filled with a low-volatile liq. such as FRIGEN 13 B1. This is heated by solar radiation to a temp. of 60 degrees C, producing a pressure of 35.3 kg/cm2. This pressure is allowed to expand in an expansion turbine or a cold gas turbine to a pressure 16.5 kg/cm2 at + 25 degrees C (under Central European conditions). The pressure relift is achieved by condensation in a suitable condenser. A feedwater pump conveys the liq. again from the condenser to the solar heat collector. The pressure differential from 35.3 kg/cm2 to 16.5 kg/cm2 is utilised in the turbine for the generation of electric power. As an alternative, a heat pump can be inserted in the circuit to reduce the temp. of condensation.

Title: Electrode control system for electric arc furnace - monitors electrode currents and voltages for control signals for depth of electrode immersion
Inventor: BRETTHAUER KARLHEINZ PROF DR I
IPC: H05B7/148
Filed: 1979-08-29
Abstract: The system controlling the depth of immersion of the electrodes (1,2,3) in the melt of an electric arc furnace uses a control system which monitors the change of inductivity due to the current passing through them. Each electrode receives current from the secondary winding of a transformer in a circuit known as a knapsack circuit. Each electrode is connected with a measuring line, with a common point (0) formed by the molten bath, and with outer connections to a switching point (8) so that the outputs can be connected to the electronic control unit. Correction values are obtained from the shift of the arc voltages and currents which are added and the differences formed with the quotient of the bath voltages are used as a value for adjusting in the depth of immersion. In each high current path is a magnetic voltage measuring device, each connected to an amplifier and a multiplier. The measuring transformers for each high current path are connected in pairs to an integrator followed by the equalising circuit.

Title: Control circuit for switching on electronic appts. - has capacitor powered transistor operated by base input signal and holding over switched on circuit
Inventor: KARBOWSKI GEORG DIPL ING
IPC: H01H47/04
Filed: 1979-10-10
Abstract: The control circuit is for switching on power to electronic or electrical appts. by sending a control signal into the controlling transistorised amplifier. The ac supply (14) is used to charge a capacitor (7) so that a ready source of power exists for the transistor (5) to operate with its collector load relay (3) when the control signal is received at its base (6). The transistor (5) and relay (3) get their holding current from the centre tap (13) of the equipment input transformer (1) via a diode (12), resistor (11), zener (8) circuit. The relay (3) is used to connect (2) the power supply (4) directly to the input transformer (1) of the equipment. The charging current for the capacitor (7) is via a high resistance (10) and therefore insufficient as holding current, hence the separate holding supply from the then switched-on transformer primary.

Title: Synchronisation of multiple branch data network transmissions - uses time division multiplexing having synchronising circuit at each interconnection
Inventor: TEICH GEORG DIPL ING
IPC: H04J3/06
Filed: 1979-12-20
Abstract: The circuit is used to assist in maintaining time frame synchronisation in various network branches. At each interconnecting point with the main transmission channel and spur, a time frame is generated which is matched to the characteristics of the spur, in particular, the signal transmission time for both the receive and send channels of the spur. The receive channel (EL) of a spur is interrupted with a synchronising pulse generated at the connecting point (NK). The pulse, undetected by coupled receivers, is retransmitted by the spur end station (ZE) on the send channel (SL). Connected subscriber equipment recognises this time interval as indicating time being available for transmission of data into the network (SL2). The necessary synchronising pulse control is carried out at the interconnector (NK).

Title: Receiver automatic tuning circuit selecting strongest signal - compares sound picture from two receiver stages after automatic search sequence
Inventor: BOEHMER HANS DIPL ING
IPC: H04H1/00
Filed: 1980-05-27
Abstract: The device tunes the receiver to the transmitter providing the strongest signal from a group of transmitters providing the same programme. It uses two reception stages each with a frequency synthesiser and a phase-locked loop. A sound picture is obtained from the transmission received by one stage, with the other stage effecting a search sequence to obtain the same sound picture. These are then compared with the frequency of the transmitter being stored when the comparison is positive. The search sequence is repeated when the received signal amplitude from either stage drops below a given threshold level, to locate a transmitter providing the same sound picture, but having a stronger signal. The tuning device may employ a logic circuit with microprocessor control. The device is incorporated in a radio receiver mounted in an automobile or on board a train etc. to avoid manual re-tuning when travelling between zones covered by different transmitters.
