No. 28032.—5th July, 1910.—AUGUSTIN GEORGE PIUS MORGAN, of Box 91, Palmerston North, New Zealand, Dairy Factory Manager. An improved appliance for preventing or allaying the formation of froth on milk and other liquids.

Extract from Specification.—Employ the well-known feature of a cone having its apex inserted in the end of a pipe through which milk is forced by a pump. A collar screwed upon the end of the pipe forms a seating for the cone, and has projecting arms by which the valve and the seating may be readily removed from the pipe for cleaning purposes. The cone is spring-operated, and acts efficiently independently of the amount of milk passing through the pipe.

[NOTE.—The above extract from the specification is inserted in place of the claims.]

(Specification, 2s. 6d.)

No. 28069.—12th July, 1910.—JESSE MEAD, of Warkworth, Auckland, New Zealand, Builder. A combined petroleum oil and carbide gas generator.

Extract from Specification.—The invention lies in combining the application of a petroleum oil, preferably kerosene, to carbide of calcium in the manner understated, so as to produce a gas superior to and richer than acetylene gas, and which can by the intermixture of compressed air with it be made an equivalent for all purposes of coal-gas. The plant consists of an outer water-tank and inner generator-case, and a central carbide and petroleum oil and carbide holder and gas-generator, a tank overhead for holding the oil, a pipe connecting the tank to the holder and generator, and various cocks, pipes, and fittings, which are all detailed in the description.

No. 28089.—14th July, 1910.—GEORGE LESTER BURTON, of Christchurch, New Zealand, Acetylene Expert. Improved acetylene-gas generator.

Claims.—(1.) In a device of the class described, the combination with a gasometer, of a conical chamber containing water depending from the underside of the water-tank and provided with a perforated tray adapted to hold carbide, a spout through which the carbide is fed into the tray, and a pipe adapted to convey the gas from the upper end of the conical chamber to a gasometer, substantially as and for the purpose set forth. (2.) The improved acetylene-generator substantially as described and explained, and as illustrated in the drawings.

(Specification, 2s. 3d.)

No. 28134.—21st July, 1910.—JAMES SIMPSON ISLAND, of corner of Brock Avenue and Florence Street, Toronto, Canada, Dental Surgeon. A process of extracting precious values from ores.

Claims.—(1.) A brake-mechanism comprising a brake-drum, a pair of adjacent expansible brake-shoes arranged within said drum, and rock-shafts for respectively expanding said shoes arranged on diametrically opposite sides of the drum, each shaft constituting an anchor for the opposite shoe. (2.) A brake-mechanism comprising a brake-drum, a pair of adjacent split annular brake-shoes arranged within said drum with their points of severance upon opposite sides thereof, cams for expanding said shoes arranged in the splits thereof, and cam-shafts for said cams, each constituting a pivot-anchor for the opposite shoe.

[NOTE.—Here follow two other claims.]

No. 28172.—29th July, 1910.—HENRY ELLSWORTH WOOD, of 1734 Arapahoe Street, Denver, State of Colorado, United States of America, Engineer. Ore-concentrators.

Claims.—(1.) The process described of recovering the values from metalliferous ores, which consists in feeding or delivering the ore in a thoroughly dried and finely comminuted state in a uniform stream upon the surface film of a moving sheet of water, discharging said sheet into and across the surface of a body of water without breaking or impairing the surface-film, and so as to maintain a surface stratum continuously flowing at a relatively slower rate over the body of water to permit the submerged particles to settle, and directing the surface-film with the particles supported thereon into a suitable receptacle.

[NOTE.—Here follow seven other claims.]

(Specification, 13s. 3d.)

No. 28175.—5th September, 1910.—JAMES MCLAREN, of Auckland, New Zealand, Thong-maker. An improved wire-bound thong.

No. 28180.—30th July, 1910.—ARTHUR LYELL BROOKE, Gentleman, and ROBERT DUNBAR MACKINTOSH, Doctor of Medicine, both of 103 High Street, Mortlake, Surrey, England. Improvements in alloys.

Extract from Specification.—The alloy is produced by melting aluminium in a suitable crucible, and then allowing it to cool. When cold an oxide of nickel is added and covered with “light” or “heavy” magnesium oxide, mixed with a material which has a reducing tendency, such as powdered wood charcoal. The crucible is then heated to a temperature of 1,600° C., whereupon metallic magnesium is added, care being taken that the molten metal is kept well covered with the reducing-material in order to prevent ignition and oxidation. It is also important to stir the mixture of aluminium and nickel with a carbon rod before adding the metallic magnesium, in order to promote the admixture of the metals.

[NOTE.—The above extract from the specification is inserted in place of the claims.]
