Patent EP-0015663-A1 (EP)
Inventor: WEST NORMAN
IPC: H01H36/02
Filed: 1980-02-13
Abstract: A float operated electrical switch assembly has a housing (10) fitted to an opening in a container wail (14). A float (19) follows the liquid level and is pivoted with a primary magnet (18) about a pivot axis (17). A pivotal secondary magnet (21) acts in repulsion with the primary magnet (18) through a non-magnetic wall (20) of the housing (10). The movement of the secondary magnet (21) causes at least one control rod (48) to reciprocate. A switch contact (32) is normally held under the resilience of its carrier leaf soring (38) in engagement with a fixed switch contact (33). The contacts are opened by movement of the control rod (48) moving the switch contact (32) against the resilience of its carrier.

Abstract: In a method of making a shaped structure from sheet material comprising reinforcing elements such as fibres bonded together by a thermosetting resin, said sheet material is formed into a shaped structure by pneumatic pressure applied to it by a flexible substantially air-impervious film (1), preferably of cast, extruded or calendered thermoplastic material, while it is enclosed between that film and a second flexible film (5). The method is specially applicable to the moulding of carbon-fibre-reinforced sheets (2,3,4) into laminated structures.

Abstract: ulti-coloured detergent bars can be manufactured by extruding detergent material through a mutti-apertured plate in a detergent plodder and injecting a visually distinctive liquid at the plate. The liquid is distributed throughout the detergent .material in the form of striations as the material is compressed in the extrusion cone. 
     A specific form of external striping and the use of increased amounts of injected liquid can be achieved by having some of the apertures positioned peripherally on tne plate. These apertures form 'walls' of extruded materials which constrain the liquid into stripes. 
     The manufactured bar has a distinctive appearance because the external striations are wider than the internal striations.

Abstract: The rapid regeneration of used activated carbon particles employed in the purification of gases or liquids, particularly water, is effected by means of a relatively inexpensive apparatus in which the carbon particles (1) are allowed to fall under gravity through a pathway formed by an eiec- trode assembly comprising two vertically extending series of horizontally disposed plate electrodes (5) und (6) which are offset so that the members of one series are interjacent those of the other series and may overlap, whilst one of the series of electrodes (5) is rotated about the vertical axis of a closed vessel (9) housing the electrode assembly. As the carbon particles fall down the pathway a high voltage electric current is fed to the electrodes so as to cause spark discharges to occur between the carbon particles as they travel through the gaps between the electrodes, resulting in the instantaneous generation of high temperatures which cause the adsorbed substances in the carbon particles to be desorbed without consequential damage to the activated carbon structure. The hot reactivated carbon particles can be cooled in a cooling tank (17) containing water (18).

Abstract: The procedure according to this invention applies to the polymerization of catalyzed organic monomers, preferably with saturated pressurized steam. Alternatively, instead of steam, hot water treated with a neutral organic salt may be used. In both cases, the medium is recovered and re-used in the cycle. 
     To perform the complete procedure, the invention provides for a treatment of plant or yard prefabricated objects in which they are successively passed through a drying tunnel, into a vessel containing the catalyzed monomer, into a chamber containing steam or treated hot water for the polymerization, and finally into a radiant heated area. 
     For objects cast in situ, the invention provides for the use in successive phases of a series of mobile heat radiating panels, or of monomer containers, either with steam or treated hot water, according to the specific treatment phase. (Figs. 3,8)
