Title: Highly thermally efficient solar energy water heater - comprises steel heat receiver connected to heat exchanger enclosed in polyurethane foam fibre glass shell having lead-free glass windows
IPC: F24S10/70
Filed: 1977-02-04
Abstract: Solar energy heater is used industrially or domestically for providing hot water for heating and sanitation. It comprises an outer case made from a polyurethane foam shell in a moulded fibre glass covering, closed at the top by two panes of lead-free glass which retain between them a layer of air. The heat receiver, made from sheet steel, which is connected to the heat exchanger, is enclosed within the case. A polished metal reflector is placed between the lower surface of the receiver and the base of the outer case. Contact between the outer case, receiver and reflector is kept to a minimum. The internal design of the receiver is such that the liq. is made to travel a large distance through, the receiver, thus maximising the heat energy absorbed. The limited contact between the receiver and the outer casae minimises the heat loss by conduction. The efficiency of the heater is twice as good as that of a traditional heater. It allows the prodn. of very high temps. with an efficiency of >50%. It can be used in cold but sunny areas.
Patent FR-2382812-A1 (FR)
Title: Switched mode power supply for colour TV - has capacitor across transformer primary to reduce natural frequency of oscillation, and gate in switch control circuit (BE 1.9.78)
Inventor: IROULART CLAUDE
IPC: H02M3/28
Filed: 1977-03-03
Abstract: The switched mode power supply is designed to provide the supply voltage for a colour T.V. receiver's deflection circuits. The switching transistor and the rectifier need not be designed for extremely high loads, while satisfactory operational efficiency is maintained. Moreover, the circuit is simplified so that the diode modulator or similar circuit arrangements can be dispensed with. The natural frequency of oscillations of the transformer primary, the latter forming a series-circuit with a controlled switch is reduced by means of a capacitor connected in parallel with the transformer's primary. The transistor-switch ddrive or control circuit contains a gate, so as to prevent the transistor-switch being made conductive before the end of transformer primary winding's oscillation set up when the transistor is blocked.
