Title: Solar or terrestrial heat energy based electrical generator - is based on spectral transformation using thermo-photoelectric or thermomagnetic-electric transducers
IPC: H02S10/30
Filed: 1979-07-02
Abstract: The electrical energy generator uses the conversion of the spectrum of solar energy received or the conversion of terrestrial heat energy, to an electromagnetic spectrum. In the solar convertor mode the generator is based on the reception of sunlight from a parabolic mirror and lens system by two electrodes (5,6) which switch the light alternately between two outgoing light guides (7,8). Each such guide may be coiled to form the primary winding of a transformer with an associated secondary circuit (9,10). In the heat energy source case, water drawn from a subterranean source transmits its heat to thermo - photo - electric or thermo - magnetic - electric transducers supported by a thermal exchange system.

Title: Heater calorific output measuring device - uses thermistors and differential amplifier to calculate and proportion cost to each apartment
IPC: G01K17/08
Filed: 1979-10-26
Abstract: When a number of apartments are heated from a common heating source the expenses are shared in proportion to heat used. The heat used is measured from internal and external temperature sensors and the heating water temperature differential. The flow and return water temperatures for heating system are measured by thermistors (RHK, Ri) which are connected to an ambient temperature sensing thermistor (Ri). These thermistors are connected to the input of differential input amplifier (21) to determine average value. This is amplified (3) for a circuit (4) which multiplies by an adjustable factor control (Rq) proportional to heting characteristics of the heating body. An integrator (6) provides quantitative value of heat used.

Title: Control and signalling circuit for vehicle centralised locking system - includes timing circuit keeping warning lights active for preset time after opening door so that user may check state of locks
Inventor: MASSON BERNARD
IPC: E05B65/36
Filed: 1980-08-05
Abstract: The device is used for centralised locking system on a vehicle and includes four warning lights associated with the four doors. These are positioned in such a way as to be visible inside and outside through the glass. Each light is in series with a switch operated by the associated lock-operating electromagnet. The lights and switches are then all connected in parallel between the positive supply and earth via relay contacts. When the engine is running, the relay is activated and the contacts are closed so that the warning lights come on when a door is locked. When the ignition is off, the lights may only be earthed via a transistor time switch. Switches associated with each door are connected to a capacitor so as to initiate timing from the opening of any door. The lights then remain operational for several tens of seconds, to allow the user to check that the doors are satisfactorily locked before the lights are automatically extinguished.

Title: Horizontal axis wind turbine - uses variable length vanes on support electrically driven on horizontal track to face oncoming wind
IPC: F03D3/04
Filed: 1980-09-15
Abstract: The generator has a horizontal axis carrying radial vanes of variable length which are positioned square on to the wind. A screen in front of the lower half of the turbine wheel reduces wind pressure on the vanes which are moving into the wind direction as the turbine rotates. The turbine support is carried on a circular track and is electrically driven to face the wind under control of wind direction sensing vane. The turbine drives a low speed alternator, direct coupled to the shaft, generating normal mains voltage and also, through belt and pulleys, a 24V DC high speed generator which supplies power to the positioning motors, and also a hydraulic pump which provides power to adjust the length of each vane through a hydraulic cylinder incorporated in the vane, thus maintaining constant turbine speed despite varying wind speeds.
