Title: House heating system using heat pump - has heater in series with roof mounted heat exchange coils, to melt snow layer
Inventor: KOHNKE HANS-JUERGEN DIPL ING
IPC: F24D11/02
Filed: 1980-04-16
Abstract: The heating system for a house uses copper sheets (1,2) under the sloping roof, incorporating liquid circulating coils, forming a heat exchanger combined with a heat pump. This includes a heat exchanger (5) under the roof, incorporating the evaporator, connected to a unit (6) in the basement incorporating the compressor and throttle valve. This is followed by condenser (7) immersed in a hot water tank (8) for the room heater (9). Included in the supply line between the roof heat exchanger and the heat exchange coils is a heater (10) which can be switched on to warm the water circulating in the coils. This can be used so that a layer of snow on the roof will be melted, so that the heat pump can operate at its maximum efficiency. At the same time, the compressor is stopped and is not started again until the snow has melted away.

Title: Prefabricated and prestressed wall element - for combustion chamber of kiln used for baking ceramic mouldings
Inventor: BUSCHERMOEHLE GREGOR
IPC: F27D1/06
Filed: 1980-08-14

Title: Semiconductor laser output signal control - regulates laser modulation current by signal from comparator of electric and optical peak signals
Inventor: WIESMANN THEODOR DIPL ING
IPC: H01S5/0683
Filed: 1980-12-03
Abstract: To counter laser characteristic changes, due to temp. effects and ageing, the output signal is controlled by regulating the modulation current of the semiconductor laser (LD) by an appropriate signal. The latter is derived by comparison between the peak values of the electric input signal (S) and the optical output signal of the semiconductor laser respectively. The control circuit includes a control amplifies (V2) in series in front of the semiconductor laser. The amplifier operation is controlled by an output signal of a differential amplifier (V3). One input of the latter receives an input signal in front of the control amplifier, while the other input receives an output signal of an opto-electric transducer (FD), both via peak value rectifiers. The transducer converts the semiconductor laser optical signal into an electric one.
