The combination of a rotatable ring, and a yieldingly supported casing for said ring. (15.) The combination of a ring-casing, and a ring movable radially and axially relatively to said casing, said ring and casing having adjacent surfaces curved in the direction of their axes. (16.) A drag for a spinning- or twisting-frame consisting of a bell-shaped ring. (17.) A drag for a spinning- or twisting-frame consisting of a bell-shaped ring having a race to receive a traveller. (18.) The combination of a radially-movable ring, means for limiting the radial movement of said ring, and a traveller revolvable on said ring. (19.) The combination of a ring axially and radially movable relatively to the spindle, said ring having a race, a traveller revolvable about the said race, and means for limiting the described movement of said ring. (20.) The combination of a rotatable ring having a race, a traveller revolvable about said race, and yielding means for limiting the radial or axial movement of said ring. (21.) The combination with a rail, and a yarn-drag supported thereon, of a ballooning regulator carried by the rail and adapted to enclose the bobbin, said regulator having rocking weighted arms for releasing the bobbin when moved laterally. (22.) The combination with a rotatable ring capable of axial movement relatively to the spindle under the stress of the yarn, and means for limiting the movement of the ring, of a device for regulating the ballooning of the yarn.

No. 12282.—11th July, 1899.—JAMES SWINBURNE, Engineer, and EDGAR ARTHUR ASHCROFT, Mining Engineer, both of Grosvenor Mansions, 82, Victoria Street, Westminster, London, England. Improvements in the treatment of sulphide ores.

[NOTE.—This is an application under section 106 of the Act, the date given being the official date thereof in Great Britain.]

Claims.—(1.) Treating sulphide ores, suspended in or mixed with a fused chloride or chlorides, with chlorine, substantially as described. (2.) Treating metallic sulphides with a fused chloride or chlorides, and passing chlorine through the mixture, substantially as described. (3.) Obtaining sulphur from sulphide ores by passing chlorine through a mixture of the ore and a fused salt, substantially as described. (4.) Treating ore mixed with chloride in a converter heated essentially by the chemical action of the chlorine. (5.) The cyclic process of treating ores suspended in fused salt with chlorine, and electrolytically decomposing the resulting chlorides into metal and chlorine. (6.) As a step in the described process, separating from the fused chlorine-treated charge iron and manganese, by precipitation as oxide, substantially as described.
(Specification, 5s. 3d.)

No. 12284.—4th January, 1900.—ALEXANDER STORRIE, of Dee Street, Invercargill, New Zealand, Implement Agent. Improvements in ridge-drills.

Claims.—(1.) In a ridge-drill, a concave roller caused to revolve by gearing from the travelling-wheels of the implement, or from the axle upon which said travelling-wheels are fixed, substantially as and for the purposes described, and illustrated in the drawing. (2.) In a ridge-drill, a concave roller journaled in a pivoted frame, a chain-pinion connected to said roller, connected by a drive-chain with a sprocket-wheel receiving motion from the travelling-wheels of the implement, substantially as and for the purpose described, and illustrated in the drawing. (3.) In a ridge-drill, a concave roller connected by gearing with and revolved by the travelling-wheels of the implement, and a scraper formed of approximately the shape of the contour of the roller, and designed to remove earth adhering to the surface thereof, substantially as specified and illustrated. (4.) In a ridge-drill, a frame comprising two corresponding bars pivoted upon opposite sides of the frame of the implement, a concave roller journaled in said frame, a frame journaled upon the axle of the roller, to which is secured a coulter, a scraper designed to clean the periphery of the concave roller carried upon the coulter-frame, a sprocket-pinion upon the axle of the concave roller, a chain connecting said pinion with a sprocket-wheel fixed upon a travelling-wheel of the implement or to the axle thereof, substantially as specified and illustrated. (5.) The improvements in ridge-drills substantially as specified, and illustrated in the drawing.

No. 12290.—10th January, 1900.—ALEXANDER IMSCHENETZKY, of 20, Snamenskaia, St. Petersburg, Russia, Colonel. Improvements in and relating to the manufacture of fire-resisting materials.

Claims.—(1.) The improved method of introducing silica into asbestos or other sheets consisting in causing the reacting liquids for forming silica to mix in proper proportions upon the constituent webs or layers of the sheet during the formation thereof, substantially as described. (2.) The combination, in a machine for manufacturing asbestos cardboard and like material, in the manufacture of fire-resisting materials useful for building purposes and the like, of rollers each of which is supplied with one of the reacting liquids for forming silica, adapted to successively engage with the drum or cylinder on which the cardboard is formed, so as to deposit the reacting liquids for forming silica in proper proportions upon the constituent webs or layers of the cardboard in course of formation, substantially as and for the purposes described.

(2.) In oil- or gas-engines, the forming of a local compression-space between the cylinder and piston by means of a projection upon the latter fitting into an aperture in a partition in the former, or vice versâ, when approaching the end of the stroke, whereby the charge of oil, or vapour, or gas may be forced through a passage leading from the confined space so formed to the rear of the piston, for the purpose of there or otherwise firing the same in manner substantially as shown and described. (3.) In oil- or gas-engines, the forcing of oil, vapour, or gas at or toward the end of the compression-stroke of the piston into the explosion-chamber of the cylinder, for the purpose and in manner substantially as shown and described. (4.)
