Patent FR-2269207-A1 (FR)
Title: Accumulator battery charging system - maintains charging current at a max safe level using sampling cct. and charging control cct.
IPC: H02J7/00
Filed: 1974-04-25
Abstract: The lead acid accumulator charging is designed to optimise the level at which the charging is carried out and minimising the risk of electrolyte hydrolysis and consequent loss in lifetime of such batteries. The process interrupts the charging current periodically and measures the fall in potential at the battery terminals and also monitors the charging current level such that it does not exceed the battery acceptable level. The individual battery or bank of such batteries (BA) forms part of a control loop and is fed from a ballast circuit (B) including thyristor power stage controlled from an integrating system (S) limiting the current (Ic) to the batteries. The battery output circuit feeds the sampling circuit (E), the voltage measurement stage (T) and the comparison circuit (S).

Title: Fixing socket for Bowden cable sheath - U-section clip retains cable in plastic socket
IPC: F16C1/10
Filed: 1974-05-02
Abstract: The plastic socket (1) is attached to a metal sheet or side of a box by a slotted tubular end (6) with tapered external surface so that the diameter can contract in order to pass through the fixing hole. A plug (7) expands the hole in the socket to retain the socket firmly against the plate. The cable sheath (10) passes through transverse holes and is secured by the inward curving legs of a U section clip (8) made of sheet spring steel. The legs spring inwards when pushed past the cable causing the base of the U to bulge upwards providing a recess by which the clip can be removed when necessary.

Title: Synthetic matls. from thermoplastic and elastomeric waste - esp. from insulated wire scrap, without damage to metals
IPC: C08J11/06
Filed: 1976-01-16
Abstract: Synthetic materials are recovered from waste containing thermoplastics and elastomers, with or without metals, by mixing the waste from which the synthetic materials are to be recovered, with sodium chloride which has been brought to >=130 degrees above or below that of the ambient, and agitating the mixture until the synthetic material has been reduced to small particles. The agglomerated sodium chloride is then separated mechanically and the remainder is removed from teh synthetic material by washing. The sodium chloride may be raised to 350 degrees C or lowered to around -150 degrees C. If mixed with the waste at this temp. the thermoplastics crystallise, and after the agitation, the product is raised to room temp. and the salt removed by washing. Recovers the waste plastics in the form similar to the original, so that it can be re-used. Copper is recovered without its being burned and without a further cleaning operation being necessary.

Title: Roll nip die for extruding hot plastics sheet - to produce e.g. PVC webs at relatively low shear rates and temperatures
IPC: B29C48/08
Filed: 1976-05-17
Abstract: A die device for extrusion of hot plastic sheet comprises a cylindrical chamber incorporating a coaxial rotor for distributing through the chamber melt received at one or more inputs from an extruder or equivalent source.
