Title: Decoder for SECAM chrominance information - has gating circuit sensitive to given subcarrier frequency for splitting and sync signal
IPC: H04N11/18
Filed: 1974-07-31
Abstract: Decoding of chrominance information in secam colour television systems is performed at the receiver by a circuit ensuring positive action when identification lines are present. Automatic amplitude limiting ensures correct colour saturation and a matrix circuit ensures automatic balancing of colour tint. The chrominance subcarrier signal input passes through a tuned circuit to a gate and there through a delay channel and direct channel in parallel to a permutator. This receives a signal from the tuned circuit via gating circuits to provide a synchronisation signal when identification lines are present. During this time short circuits are opened to allow signals on the two channels to pass through to a mixer from adjustable limiters and gates and modulation extractors. Luminance signals are mixed with the signals prior to passing through triple level controlled amplifiers.

Title: Central heating system with heat pump - with excess heat stored in water circulated past refrigerant condenser
Inventor: LABBEY PATRICK DE
IPC: F25B29/00
Filed: 1974-09-27
Abstract: The central heating system works on the principle that when a room is too hot, the excess heat is extracted and stored in water and when the room is too cold, the heat stored in the heater is transferred to air which is blown into the room. A heat pump system is used and has a condenser cooled by water circulation and an evaporator. The water circulation system includes a water/air heat exchanger, a fan being used to blow the air. The evaporator extracts heat from the room in response to signals from a thermostat which also controls the operation of a refrigerant compressor, a further fan being used to pass air from the room over the evaporator.

Title: Longitudinal seam welding of tubes in lamp post mfr. - using set of jacks to adjust edges of seam prior to welding
IPC: B21C37/08
Filed: 1974-10-07
Abstract: Device for closing the gap between the two edges of a tube with a polygonal or circular cross-section formed by bending, the gap being closed prior to continuous longitudinal seam welding. The novelty is that the device comprises three jacks, two of which are employed to close the gap, whereas the third jack is utilised to prevent the two edges from overlapping, the angles between the jacks being precisely adjusted; and the jacks are used in conjunction with a V-block where the included angle of the "V" is 135 degrees. The device is used e.g. in the mfr. of street lamp posts by longitudinal seam welding a tube with an octagonal cross-section, the device reducing the gap between the two edges being welded towards zero.

Title: Solderless connector for printed circuit boards - has modular construction and uses single sprung element forming self cleaning contact array
IPC: H01R12/70
Filed: 1975-04-04
Abstract: The electrical connector is particularly intended for use with printed circuit boards, and provides an accurate and reliable solderless connection and a self cleaning contact array.

Title: Mould for shaping wound reinforced pipe ends - to obtain angular shapes prior to curing the resin
IPC: B29C70/46
Filed: 1975-04-07
Abstract: Complementary mandrel and split mould clamps are used for shaping the end of a pipe made by lay-up of resin impregnated rovings. The material is laid up to a slightly excessive thickness and then squeezed to shape before being hardened. Part of the mandrel if left uncovered to align the ends of the mould clamps. The clamps include a false cavity beyond the end of the required pipe profile to accept the displaced excess material. Methods capable of producing more angular changes of profile than can readily be achieved by using programmed wind up patterns without involving subsequent reshaping. It avoids waste of material and effort associated with making oversize cured mouldings and machining the ends to shape.
