Title: Compression type heat pump - has statothermal compressor connecting first heat exchanger to compressor set connecting second exchanger to expander
IPC: F25B1/10
Filed: 1975-09-12
Abstract: The compression-type heat pump contains a cooling fluid and, in series, a first heat exchanger in which the fluid absorbs the excess heat transmitted by a heat-conductive fluid from a cold source, a compressor set, a second exchanger where it rotors heat to a user circuit, and an expander returning it to the first exchanger. The first exchanger is connected to the compressor set by a stato-thermal compressor, which also connects the second exchanger to the expander. At the outlet from the compressor set is a three-way valve, enabling the cooling fluid to be tapped off to the thermal compressor or delivered directly to the second exchanger. At the outlet from the latter is a second three-way valve, allowing the fluid to be delivered directly to the expander.

Title: Protection unit for high tension transformers - guards against effect of short circuit surge in secondary
IPC: H01H71/44
Filed: 1975-11-21
Abstract: The unit consists of a switching mechanism whereby a metallic armature(3) moves towards the core(2) of the H.T. transformer. When a large current from a surge or short-circuit, appears in the secondary circuit, the resulting increased magnetic flux in the core of the transformer attracts the armature. The increase in the flux is proportional to the increase in the current. With the armature displaced, a mechanism comes into operation such that the current to the transformer is cut off. A manually-operated pressure switch restores the transformer connections.
