Title: Central heating and air conditioning system - uses water as main heat exchanger for circuit which includes solar heater and heat pump
IPC: F24D11/02
Filed: 1979-12-07
Abstract: The central heating and air conditioning system for a building uses a heat pump and a heat exchange coil buried in the ground under the building. This is also supplemented by a solar heating system using a collector panel on the roof. Apart from the refrigeration circuit, the system uses water as a heat exchange medium, and this can be used to transfer heat between the heat sources including heat from the building itself, and for a hot water supply. An anti freeze substance can be added to the water. To control loss of heat between summer and winter coditions, a motorised control valve is operated by a programmed device. The circuit also uses exhaust and extraction fans at an upper level and an under floor heating coil for an intermediate floor.

Title: Fuel safety cut=out appts. for gas or oil burner - has two contacts between burner control thermostat and burner to inhibit burner when flue blocked
Inventor: WEITSCH ANDREAS
IPC: F23N5/24
Filed: 1980-02-25
Abstract: The circuit operates a flue closing valve to reduce heat loss from oil or gas fired burners, and is configured to ensure that burners cannot be ignited unless the flue valve is fully opened, and safeguards against faults due to welded contacts in the control circuits. The valve is controlled by the thermostat (3) which controls the burner (7). The contacts are introduced in series between the thermostat and the burner. The first is a limit switch (1) operated by the full opening of the flue valve. The safeguard against the condition where the limit switch (1) contacts weld, owing to high current, the second contact (2) is operated before the flue valve is fully open, and after the flue valve has part closed, and is therefore always switched at no load. If the first contact has welded, the opening of the second contact connects the burner supply current through a low current fuse (5) which opens the supply circuit to the flue valve motor (4).

Title: Tubular solar heat collector - has automatically positioned reflecting mirrors controlled by fluid circuit to concentrate energy on absorber
IPC: F24S23/77
Filed: 1981-03-09
Abstract: The heat collector is a tube (27) connected to a fluid circuit and mounted on a frame (3). The frame supports two sets of mirrors (11,17) which reflect the rays of the sun onto the absorber. The mirrors are interlinked to move in unison. A positioning drive below the collector comprises two transducers (28,29) in series with an expansion chamber (40). The two transducers have fins (30,39) with absorbant surfaces facing the sun's rays. In the position of equilibrium the rays are concentrated on the collector. When the sun's position changes one transducer is heated and causes the fluid in the circuit to expand and, through the linkage, rotate the mirrors back into line.
