Title: Improvements in and relating to the production of moulded shaped bodies from a mixture of fibre and a synthetic resin emulsion
IPC: D21J3/00
Filed: 1947-08-20
Abstract: In the production of forms for use in shoe, hat and wig making, &c., where it is necessary to retain shaped material temporarily by pins, or where the forms are subjected to heat and moisture and are required to absorb and resist the action of moisture and steam, a wet mass of fibres, such as Kraft wood pulps, sulphite, asbestos &c. in which a resinous or other bonding agent is dispersed and which has been drained sufficiently on a gauze or like surface so as to be readily handled as a web, is transferred to the surface of a mould to form a layer.  The layer is then subjected to light compacting pressure through a yielding absorbent pad which takes up excess moisture.  Further layers are applied by the same process until the moulding is of the required thickness.  The first layer may contain pigments whilst the subsequent layers have preferably less moisture content and may be composed of a cheaper material having less bonding agent.  By varying the proportion of resin solids to fibre and degree of compactness, the thermal insulation as well as the absorption ability may be varied.  Oil, wax, grease, &c. may be applied to the mould face before the initial layer is deposited to assist in the removal of the moulding.  Metal gauze, threads, or metal particles may be incorporated in the moulding.  The preferred bonding agent is a thermosetting resin, e.g. urea formaldehyde which flows or cures at a moderate temperature, say 100 DEG C., in which case the final treatment of the moulded body is a stoving or other heat treatment. If a thermoplastic agent is used the final treatment will comprise stoving to effect drying and soften the thermoplastic, followed by cooling to solidify the thermoplastic in its welding relationship to the fibres.  The finished moulding may be sandpapered, filled or patched, readily worked by woodworking tools and suffer the insertion of screws nails &c. Plaster or soft metal moulds may be used in this low pressure process.

Title: Process for the manufacture of magnesium ammonium phosphates poor in water contents
IPC: C01B25/45
Filed: 1930-08-01
Abstract: In a modification of the process of the parent Specification gaseous ammonia is added to a mixture of phosphoric acid or alkali phosphate such as potassium phosphate, and magnesium salts such as the nitrate, chloride or sulphate, or potassium waste liquor, or magnesium oxide or hydroxide, whereby crystalline magnesium-ammonium phosphate is obtained.  The ammonia gas may react on the mixture either in solution or suspension, or in the solid state.  In the former case, after separation of the double salt, the liquors may be treated with lime for the recovery of p  ammonia, this step, however, being unnecessary where magnesium oxide is used.  Alternatively the ammonium salts may be crystallized.  When an alkali phosphate is employed, the corresponding alkali salts, say, potassium nitrate, may be crystallized, separately, or with the ammonium salts, for use as a fertilizer.  If, however, magnesium ammonium phosphate is not separated, these salts may be crystallized thereon.  In the case where the reactants in the solid state are treated with gaseous ammonia, a solid manure containing magnesium, nitrogen, phosphorus and sometimes potassium is obtained.  Other manures may be added prior to or subsequent to the reaction.ALSO:In a modification of the process of the parent.

Abstract: 816,276. Sifting apparatus; pneumatic separation. WHEELABRATOR CORPORATION. July 24, 1957 [Jan. 30, 1957], No. 23507/57. Class 117 [Also in Group XXIII] A machine in which abrasive particles, e.g. steel shot or metal pellets, are thrown at high velocity on to workpieces e.g. metal castings to remove sand or otherwise clean them or mould plastics, sheets &c. to remove burrs and flashings or to provide roughness for preparing for anchorare or for printing, has means for separating re-usable abrasive from the spent abrasive and returning the re-usable abrasive to the throwing means, the separating is effected by a shaker screen followed by an air separation area. As applied to a machine in which abrasive is thrown by one or more wheels at workpieces while they are being tumbled in a trough formed by a conveyer, spent abrasive is received in a hopper 10 from which it drops on to a screen 26 carried by a reciprocating plate 24. The plate 24 extends rearwardly beyond the exit opening 20 of the hopper, and the screen 26 extends rearwardly beyond the edge of the plate. Particles passing through the screen 26 fall from the edge of the plate 24 into a stationary trough 38 from which they overflow. Below the trough 38 is a dividing wall 44 between a chamber 46 for acceptable abrasive and a chamber 48 for material separated by air 50 flowing through the curtain of spent abrasive falling from the trough 38. Abrasive collects in the trough 54 of chamber 46 and is passed by a screw conveyer 56 into the boot 18 of an elevator 16 which lifts it to the hoppers feeding the throwing wheels. The refuse collects in the trough 52 of chamber 48 and is removed by a screw conveyer 60. The air is drawn by a fan or other exhaust means in communication with an opening 62 in a header 64 having openings 66. A plate 70 extends inwardly and downwardly from a frame plate 72 to define the upper wall of inlet slot 68 for the air. The frame plate 72 receives material falling from the end of the screen 26.
