Abstract: 1,082,362. Mineral-mining cutter picks. COAL INDUSTRY (PATENTS) Ltd. Jan. 12, 1965 [Jan. 17, 1964], No. 2254/64. Heading E1F. To lengthen the life of a cutter pick the pick is formed to have a linear cutting edge defined by two mutually inclined faces defining rake and clearance faces with positive rake and clearance angles so that as the pick becomes worn in use it can be displaced to another position in the holder means therefore so that the rake and clearance faces become interchanged whilst positive rake and clearance angles at the tip are maintained. discharge openings incorporated a pump 2 having a casing 3, within which is a movable diaphragm 4 acting as a common wall between a soil chamber 5 and a flushing water chamber 6, an inlet valve 7 in the chamber 5 leading from the basin 1, and an outlet valve 8 controlling a discharge opening therefrom, an inlet valve 9 in the chamber 6 controlling water flow thereinto, an outlet valve 11 controlling flow therefrom to the discharge openings, and a shaft 12 in the casing 1 rotatable about its axis and movable axially, coupled to the diaphragm 4 (by a plate 22 and a pin 21 thereon in a slot 20 of the lever 19), and operatively engageable with the inlet and outlet valves 9, 10, so that rotation thereof vibrates the diaphragm 4, whilst axial movement to one position closes the valve 9 and opens the valve 11. The valves 9 and 11 are respectively engaged by arms 25, 26 of a lever 23, mounted on a pivot 24 and engageable by an end 28 of the shaft 12, spring- loaded to move to close the valve 9 and open the valve 11 and operated by a handle 14, pivoted thereto at 15 and at 16 to a bracket 13, which can only move rotatably with the shaft 12.

Title: Improvements in the production of gas from solid fuels
IPC: C10J3/46
Filed: 1950-02-06
Abstract: 668,665. Gas turbine plant. KOPPERS CO., Inc. Feb. 6, 1950. [Feb. 5, 1949] No. 3026/50. Class 110(iii), [Also in Group XII] The hot gases from a pressure-type producer gasifying a low grade solid fuel such as coke breeze are passed through a waste gas turbine which drives a compressor delivering air at the required pressure into the producer. In the form shown, the apparatus consists of a producer 9 operating at a pressure of about 15 atmospheres. Coke breeze is fed into the producer through a drier and preheater 2 and gasified therein by an upward flow of air. The gas leaves the top of the producer at about 700‹C and passes through a dust extractor 16 to a waste gas turbine 18 and is there expanded and cooled to about 300‹C. The turbine 18 is operated with such a back pressure that the exit gas can be fed through a pipe line 4 to the drier 2 through which it passes to dry the raw coke and cause dust to be removed therefrom by entrainment in the gas stream. The turbine 18 drives an air compressor 22 which delivers air through pipe 24 to the producer grate. When the power output of the turbine exceeds that required for the compressor, an electric generator 26 can be coupled to the compressor shaft.

Abstract: 1,259,823. Coated sheet materials. INTREPRINDEREA BUCARESTI PENTRU EXTRAGEREA PRELUCRAREA SI MONTAREA MARMUREI SI PIETREI DE CONSTRUCTII. 20 Jan., 1969 [20 Jan., 1968], No. 3185/69. Heading B2E. [Also in Division D1] A material for decorating buildings comprises a face layer consisting of hard granules, e.g. artificial stone or rock, bonded together by a binder which is invisible on the face of the material and a backing layer in the form of a web through the meshes of which points of the hard granules penetrate. The binder is applied in such a manner as to cover the whole surface of the granules with pellicles. Granules mentioned are of marble, alabaster, gneiss, shales and quartzites, volcanic rocks, silicon carbide, glass, polystyrene, polyvinyl chloride, polyacrylates and may be transparent or opaque, or coloured. The layer may be constituted of different kinds of granules. The binder may comprise thermoplastic synthetic resins e.g. polyvinylacetate, polymethyl methacrylate, epoxides applied in the form of aqueous dispersions, cement alone or mixed with lime and with synthetic resin binders as additives. The supporting web may be nets made of textile materials impregnated with an aqueous dispersion or solution of the synthetic resin employed as binder; steel wire screen, the wire being protected by zinc plating or by varnishing with plastics, or glass felt. The layer of granules may be rendered water repellent by spraying with a solution of a polymer. The material may be applied to a building component in the form of panels or long strips or as particles cut therefrom, using binders such as cement, or cement and lime mortar alone or with additives such as synthetic resins. The material may be covered by a transparent wear layer of synthetic resin. The material is produced by, 1) priming the supporting web, when the latter consists of textile fibres, by drawing through an aqueous dispersion or solution of thermoplastics synthetic resin to which finely ground filler of the material of the granules has been added, 2) squeezing the web to remove excess liquid, 3) spreading on the web a layer of dry hard granules, 4) lightly pressing the layer, spraying the layer with an aqueous dispersion or solution of a thermoplastic polymer from above under pressure, 5) drying the sprayed binder by heating, 6) transforming the binder into pellicles with slight softening of the binder by heating from below by means of infra-red rays, the foil of material being carried by a conveyor belt, 7) detaching the foil with the binder still softened, 8) compressing the foil, 9) cooling it down to ambient temperature and removing the residual water vapour or the gases of gel-formation and polymerization.

In another form, Fig. 9, for viewing the inner surface of a cylinder 6, a convex reflector 7 is mounted on a plate 8 coaxially with the television camera, not shown, supported in a frame so that its lens protrudes through plate 9. To economise in space the first valve only in the head amplifier may be located adjacent the camera and its output fed by a cable to the remainder of the amplifier. In a further form, the cylindrical object is arranged more through an aperture in a dished mirror and the all-round view is reflected along the axis of the cylinder either directly to the television camera or to a plane mirror for reflection thereto.

Title: A process for the manufacture of an industrial oil

Filed: 1928-02-02
Abstract: 284,657. Ehrenreich, A. Feb. 2, 1927, [Convention date]. Void [Published under Sect. 91 of the Acts]. Fatty oils, extracting and purifying.-Livers of plagiostomi, especially sharks, are reduced to pulp, and oil is extracted, deodorized and rendered colourless. The bulk of the oil may be pressed out cold or extracted by direct heat with steam, and the residue extracted by an organic solvent e.g. benzine or trichlorethylene. The oil is filtered through infusorial earth or treated with silica precipitated by slowly warming a mixture of sodium silicate and hydrochloric acid to about 100‹ C. The oil is deodorized by distillation in vacuo with steam. A fatty acid, such as oleine, may be added if not enough is already present to combine with all the poly-alcohol it is desired to separate. Alternatively deodorization is effected by adding 2-3 per cent of lime or hydrated baryta and adding water drop by drop or passing carbon dioxide through until the alkaline earth is precipitated. Alternatively hydrogen, under not more than about 5 atmospheres pressure is passed in the presence of catalytic agents through the oil until the odorous compounds only are hydrogenated. This reaction is controlled by temperature variation, fatty acids of lesser molecular weight being preferentially hydrogenated at lower temperatures. The oil is liquid at 15‹ C, and may be used as a food or pharmaceutical produce. 'The grease of reptiles, tortoises and marine animals may be similarly treated.
