Filed: 1963-06-19
Abstract: 998,543. Two-part couplings; couplings. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. May 14, 1964 [June 19, 1963], No 24379/63. Heading H2E. [Also in Division H1] An electric circuit module comprises a plurality of conductors providing conducting faces 3 at opposite ends of the module, so that when a module is assembled end-to-end with a similar module, contact is made between opposed faces. The modules may be rotated relative to each other so that alternative connections can be made between the segments of the two modules, and an electrical device, e.g. a semi-conducting rectifier, mounted on one module and electrically connected to one of its conductors, can be electrically connected to any of the segments of the adjacent module. Each module comprises a hexagonal insulating member divided into six segments A-F, five of the segments carrying conductors passing right through the module, and the sixth one being of insulating material. The conductor in one of the segments is electrically connected to a conducting member 7 which surrounds the hexagonal member but does not extend for the full depth of the module. This conducting member 7 has integral fins 9 with holes 10 which can receive the bolts of a clamp used to hold the rectifier in position against one of the curved faces 8 of the conducting member 7. The module has a hole 6 along its axis to accommodate a rod 30 on which can be assembled a plurality of modules 40, Fig. 4. Two modules are connected to each rectifier, one to each terminal thereof, and any one of a plurality of electrical circuits can be assembled by mounting a plurality of modules end-to-end on rod 30. The rectifiers 20 are clamped to the conducting members 7 of alternate modules, and the anodes 26 are each electrically connected by a bolt to one of the projections 9 on an adjacent module 40. Cooling fins may be provided around the rectifiers.

Abstract: 1,114,922. Moulding fibrous masses. MINISTER OF TECHNOLOGY. 17 Sept., 1965 [17 June, 1964], No. 25044/64. Heading B5A. [Also in Division D1] Mouldings comprising a consolidated integral mass of acrylonitrile copolymer fibres e.g. copolymers or terpolymers of 85% acrylonitrile with methylmethacrylate or vinyl acetate alone or to which may be added phenolic resins, are produced by wetting the fibres e.g. in the form of yarn, tow, chopped tow, one or more pieces of woven, non-woven or knitted fabric, felt or tape, with an organic solvent e.g. dimethylformamide, ethyl carbonate or dimethyl sulphoxide, preferably together with at least 25% of a volatile solvent e.g. dichloromethane or diethyl ether, and heating the fibres to reduce the solvent content thereof to 75% to 80% by weight of the unwetted fibres prior to applying heat to plasticize the fibres which are then moulded and cooled under pressure before removal from the mould for subsequent removal of residual solvent by drying at ambient temperature or, when heated to 50 C., in an air stream or under vacuum. The impregnated fibres e.g. when wound as yarn containing 75-85 % solvent on to a core, are heated between the platens of a moulding press at 60-110 C. to a temperature sufficient to cause some plasticization prior to applying a light moulding pressure e.g. for 5 minutes, followed by full moulding pressure e.g. 8000 p.s.i. for 15 minutes when the bulk of the solvent is expressed and the moulding is removed from the mould after cooling to 40 C.

As shown, a frame 11 pivoted in the side arms 101 of a base 10 on which a receiving platen as of rubber or a plate 15 supported by recessed springs 16 and located by guide pins, has a rectangular aperture surrounded by a recess'in which a glass plate 18, a negative 19 and a photographic paper sheet 12 are located by a metal strip 131 carried by a leaf spring 13 on the frame and having ears adapted to seat in recesses in the frame, the negative, paper sheet, and glass plate seated in the recess in the frame being held by a turn button in the side opposite the spring. When the frame is raised, a block 141 on the back rest 14 protrudes through the frame aperture to move the plate 18 off its seating and raise the spring to facilitate removal of the negative and paper sheet. An L-shaped adaptor may be inserted in the frame if a smaller negative and printing sheet are used. The frame may be held against the base by a clip when the receiving platen fits within the aperture in the frame. The first Provisional Specification describes a similar frame from which the glass plate is omitted, while the second Provisional Specification states that a U-shaped clip may be hinged to the base for securing the frame against it.

[Also in Group XXVI] In apparatus for the simultaneous grinding of the two surfaces of a glass ribbon 3, Fig. 1, the bottom grinder unit is driven from an adaptor plate 8 by means of cylindrical drivers 11 on one member co-operating with abutment faces on the other member, and a tubular resilient ring 17 is located between the co-operating faces of the unit and adaptor plate and housed in either of them so as to form a seal preventing the entry of abrasive fluid from the central cavity of the unit into contact with the driving elements. The ring is also capable of being inflated so as to lift the grinder unit from the adaptor plate for the purpose of repair or renewal. The grinding unit consists of a disc 2 bolted to a backing plate 6 which has a spigotjoint fit 40, 41, Fig. 4, with the driven adaptor plate 8 and is fitted with renewable abutment plates 12 on each side of a recess 13 so that the unit may be rotated in either direction by the cylindrical drivers 11; each driver is secured to the adaptor plate by a bolt 27 on which it may be adjustably rotated, in the event of wear, so as to maintain line contact with the abutment plate. The tubular resilient ring 17 is fitted into an annular recess in the adaptor plate 8 so that its upper surface, which is provided with concentric ribs 30, Fig. 8, is proud of the machined face 16 and when compressed by the weight of the grinder unit forms a seal preventing the passage of abrasive fluid to the driving elements or the spigot fit between the plates 6, 8. The ring is anchored in the adaptor plate by four equispaced branches having threaded stepped nozzles 33, Fig. 8, two of which are sealed by a cap and washer and the other two are, as shown, locked by a nut 39 and provided with elbows 38 and pipes 19 for the entry of pressurized air, water or oil for the purpose of initially expanding the ring 17 and permitting even separation of the grinder unit from the adaptor plate when dismantling is required ; the final separation is carried out by a lifting arm 26, Fig. 1, engaging trunnions 24 on the plate 6.
