Filed: 1942-12-16
Abstract: A mouldable material for wall plugs &c. is made by compounding material A, formed by partially drying to about 14 per cent moisture content the waste fibrous flesh pulp from wet or dry decortication of sisal and like plants of the Agave family with material B, formed either by treating material A for the partial or complete extraction of the water-soluble constituents, as described, for example, in Specifications 517,729 and 532,877, or for the pectic substance, as described, for example, in Specification 556,808, or by treating the plant or leaf to a chemical retting process to remove the bulk of the fibres.  For wall plugs, stoppings, &c., about 60 per cent of material A may be admixed with about 40 per cent of material B. 10-25 per cent of the extracted water-soluble constituents, or 5 per cent of the extracted pectic substance may be included.  A more plastic material for lagging boilers, boardings, ceiling mouldings and containers is obtained by mixing the materials A and B in approximately equal proportions.  For moulding into linoleum and like products, 5-10 per cent of a water-miscible binder such as rubber latex or emulsified synthetic resin, bitumen or natural or synthetic rubber is admixed with the materials A and B before or after compounding.  Sound - proof and heat - insulating boards or blocks may be made by feeding the partly-disintegrated material A and B in an aerated condition as a sliver upon sheets of fibre or like board, made adhesive with emulsified synthetic resin, bitumen or natural or synthetic rubber, and, if desired, covered with a similarly treated top board.  In the case of thick blocks, the material is sprayed with binder as it is layered.  The edges of the blocks may be sealed with casein, glue or emulsified synthetic resin or with plaster of Paris, to provide a key for grouting with normal cements in wall construction.  The material A and B may also be dehydrated, ground and mixed with emulsified or dissolved bitumen, synthetic resin or natural or synthetic rubber for moulding into articles.

Abstract: 447,817. Moulding fuel briquettes in endless chain machines. DISTILLATION A BASSE TEMPERATURE ET AUTO AGGLOMERATION DES COMBUSTIBLES, 6, Rue Francois 1er, Paris. June 27, 1935, No. 18394. Convention date, June 27, 1934. [Class 87 (ii)] Apparatus for moulding solid combustibles by the method set out in Specification 416,963 comprises an endless chain of moulds 7 moving past a truncated conical hopper 2 through which combustible material is fed by a conical screw 3. The moulds are moved step-by-step by a ratchet drive 18, 19 from a rod 16 operated by a compressed-air piston 13. During filling, the mould is closed at the bottom and held against the hopper by a pad 10 operated by a link 11 from the piston 13. After filling, the moulds are closed by a series of covers 21 travelling in an endless chain. The product is ejected by a piston 14 operated by a link 15 from the link 11. The piston 13 is operated by an electric relay which is rendered operative when the consumption of current by a motor driving the screw 3 reaches an upper limit. This ensures release and movement of the mould when the compression is completed and the piston is moved back again on release of the compression. At the initial movement releasing the mould, the chain is held stationary for a further period by an idle stroke of a crank 17 operating the ratchet drive to allow time for release before the chain moves. A lip 20 on the hopper prevents swelling as the mould is released from compression. The machine frame is in three parts, the ends supporting the mechanism, and the intermediate one can be extended as required.
