No. 17147.—28th October, 1903.—HENRY LIVINGSTONE SULMAN and HUGH FITZALIS KIRKPATRICK PICARD, both of 44, London Wall, London, England, Metallurgists. Improvements in or relating to ore-concentration.

Claims.—(1.) The process of concentrating ores which consists in bringing the pulp into intimate contact with “oil,” and thereafter with a gas, substantially as and for the purpose described. (2.) The process of concentrating ores which consists in introducing into the pulp a current of air, or other gas, charged with vaporised or atomised “oil,” substantially as and for the purpose described. (3.) The process of concentrating ores which consists in mixing the pulp with “oil,” spraying the mixture through air, and conducting the spray into water, substantially as and for the purpose described. (4.) The process of concentrating ores which consists in oiling the metal-bearing particles of a pulp, disseminating it through air or other gas, and collecting the product on water on which the oil-particles float, and through which the gangue sinks, substantially as described. (5.) The complete process of concentrating ores substantially as described.
(Specification, 4s.)

No. 17148.—28th October, 1903.—ARTHUR EDWARD CATTERMOLÉ, of 10, Woodland Rise, Highgate, London, England, Mining Engineer. Improvements in the concentration and classification of ores.

Claims.—(1.) In a process of ore-concentration by oil, the employment of the oil in small quantities proportioned substantially, as described, to the amount of the metalliferous constituents of the ore under treatment. (2.) The process of separating the constituents of ores into two parts by agitating a mixture of powdered or pulped ore, oil, and water, containing a suitable acid, or an alkali with soap or other emulsifying agent, so as by means of such agitation to agglomerate the oil-coated particles into granules or small masses, and then acting on the mixture by an up-current separator, or other classification apparatus, so as to remove the small agglomerated non-oil-coated particles from the agglomerated masses of oil-coated particles, all substantially as described. (3.) In the process described of separating metalliferous matter from gangue by the formation of granules of oiled mineral, the employment of the oil in a state of emulsion in water in presence of an emulsifying agent such as soap. (4.) The process described of separating metalliferous matter from gangue by forming granules of oiled mineral by agitation of the pulped ore in an acid liquor. (5.) The process described of separating metalliferous matter from gangue by forming granules of oiled metalliferous mineral by agitation in an alkaline liquor carrying soap or other emulsifying agent in solution. (6.) The process of separating metalliferous matter from gangue which consists in agitating the powdered mineral or pulp with an emulsion of oil in water acidulated, or containing alkaline emulsifying agent, and separating out the light sands in a classifier, and thereafter further agitating the pulps to increase the size of the granules, and separating out the heavy sands, also in a classifier. (7.) In the process of separating metalliferous matter from gangue, the employment of an emulsion containing oil in a proportion adjusted substantially as described to the quantity of metalliferous mineral under treatment, so that after thorough agitation of the pulp, and emulsion in water containing an emulsifying agent or acid, the metalliferous mineral with the adhering oil forms into granules, of sizes suitable for separation from the gangue by an up-current or other separator. (8.) In the process of separating metalliferous matter from gangue by oil, the employment of particles of material, having an affinity for oil, to assist in the formation of granules of oily metalliferous matter. (9.) The process of classifying metalliferous minerals agglomerated by oil by fractionally removing the different minerals from the oil, and liberating them from the oil-agglomerated granules by the successive use of alkaline emulsifying agents of graduated strengths, substantially as described. (10.) The process of classifying metalliferous minerals agglomerated by oil which consists in successively agitating the agglomerated mineral with alkaline emulsifying agents of varying strength or activity to free the several minerals in succession, and separating out each mineral in turn by an up-current separator or other separating-device. (11.) In the process of fractionally removing different metalliferous minerals from an oil agglomerate by the successive use of alkaline emulsifying agents of varying strength or activity, the addition of oil or oil-emulsion in the requisite small amounts to keep the granules of proper size and consistency. (12.) The complete process of concentrating and classifying ores, substantially as described. (13.) The complete apparatus for concentrating and classifying ores, substantially as described, and illustrated in drawing.

No. 17149.—28th October, 1903.—GEORGE ALBERT WARBURTON ALEXANDER, of Austral Terrace, Malvern, South Australia, Sharebroker. A new or improved machine for washing clothing and wool.

Claims.—(1.) In a new or improved machine for washing clothing and wool, a series of compartments arranged together substantially as described, each compartment being provided with a vent-hole c and a deflecting plate or hood d. (2.) In a new or improved machine for washing clothing and wool, the combination of a cross handle and a series of compartments, each compartment being characterized by having a vent-hole and deflecting plate or hood, substantially as described and as illustrated. (3.) In a new or improved machine for washing clothing and wool, characterized by the parts above specified and claimed, a bracket such as h for the reception of forceps such as j, substantially as described, and as illustrated in Fig. 5. (4.) The specified machine for washing clothing and wool, arranged substantially as described and illustrated, as and for the purposes set forth, as a combination of parts.
(Specification, 3s. 3d.; drawing, 1s.)

No. 17150.—28th October, 1903.—JOHN GEORGE PATTERSON, of Manchester, England, Engineer. Improvements in coal-cutting machines.

Claims.—(1.) A coal-cutting machine comprising two cylinders, also rams and cutting-tools worked by compressed air, the cylinders being provided with ports and passages which cause the air to pass alternately to the back end of each cylinder, and at the same time to the fore end of the other, a carriage whereon the said cylinders are so mounted as to be capable of turning in horizontal and vertical planes, an under-frame having side members of channel section for supporting the said carriage, and means for traversing the carriage to and fro along the under-frame, and holding it stationary at any desired point, as set forth. (2.) In a coal-cutting machine, a pair of cylinders, with ports, passages, and rams, formed, mounted, and operating substantially as set forth. (3.) In a coal-cutting machine, an under-frame of, by preference, rectangular and elongated formation, and having wheels with bevelled peripheries at its rear end, and spiked plates or teeth at its front end (or both front and rear ends), or similar devices, by which the frame is adapted to bed itself into the ground and resist the recoil of the machine, as set forth. (4.) In a coal-cutting machine, an under-frame of rectangular and elongated formation, having side members of channel cross section, and having wheels with bevelled peripheries at its rear end and spiked plates or teeth on its front and rear ends, an axle with ratchet wheel and pawl and pulley, and a set of chains wrapping around the said axle and passing over the said pulley, substantially as set forth. (5.) In a coal-cutting machine, a special construction, arrangement, and combination of parts, substantially as described, and illustrated on the drawing.

Claims.—(1.) A gas-producer wherein the more volatile vapours are drawn from the top of the generating-chamber and caused to pass through the incandescent fuel at the lower part of the chamber; also wherein the less volatile vapours are drawn off at a lower level and caused to pass through the incandescent fuel from the opposite side of the chamber, as set forth. (2.) In combination with the gas-producer set forth in claim 1, a water-sealed furnace-grate, as set forth.
