No. 30763.—23rd January, 1912.—Robert Dale McCarter, of 2 Norfolk Street, Strand, London, England, Engineer. Improvements in and relating to metallic railway ties or sleepers.

Extract from Specification.—The present invention contemplates the use of a resilient cushioning-member of this description, and also the use of clamping-members, hereinafter termed the clamping-dogs, the upper portions of which either engage with the base flange of the rail or are secured thereto in any suitable manner. According to this invention, the clamping-dogs are provided with one or more projections or indentations, which are adapted, when the parts are assembled, to be engaged by a transverse rod, bar, or bolt, termed the locking-member, suitably secured at its opposite ends to the upwardly extending flanges of the sleeper.

No. 30770.—20th January, 1912.—Automatic Welding Company, a corporation organized under the laws of the State of Michigan, with offices at Menominee, State of Michigan, United States of America (assignees of Marshall Burns Lloyd, of Menominee aforesaid, Manufacturer). Continuous tube mill.

Extract from Specification.—The invention resides in a machine which, in its preferred form, comprises formers or shapers, operating in conjunction with constant-speed automatic-travelling mechanism to form or shape the metal into tubing, and having corelated and coacting parts and mechanisms for heating and butt-welding the edges of the tube to close the seam thereof as rapidly as the tubing travels forward, and for controlling the relation of the welding-mechanism and the tubing so that the seam of the latter will be properly positioned or guided in proper alignment with the welding-device to accurately form the welded seam. The invention contemplates, though it is not so limited, a machine whereby the welding of the edges of the tubing is brought about by the aid of pressure accompanying the heating of the metal. The invention also consists in a machine which automatically removes the burr or ridge left at the seam by the welding operation, and also other imperfections in the surface of the tubing, and which perfects the shape and size of the tubing preparatory to its being cut into lengths and discharged from the machine. This invention further embraces a machine which polishes and finally finishes the surface of the tubing, and also a machine which automatically measures and cuts the tubing into lengths without interruption in the movement of the tubing or in the operation of the machine.

(Specification, £2 7s. 6d.)

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

No. 30777.—24th January, 1912.—Frederick Jackson, of Otakeho, Taranaki, New Zealand, Plumber. Improved means for controlling windmills.

Extract from Specification.—The invention consists in the combination with the usual control-wire for operating the gear and a lever for drawing on and for releasing such wire, of a small water-tank mounted on one end of such lever, and connected with the storage-tank supply-pipe in such a manner that when the storage-tank fills the water will pass into the tank upon the lever, filling it, and causing the lever to fall and pull the gear into its inoperative position. When the level in the storage-tank falls, the water from the control-tank will run from it, and thus permit of the lever rising under the action of a counterweight to release the gear and allow it to revert to its operative position to recommence pumping.

(Specification, 3s. 3d.)

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

No. 30785.—25th January, 1912.—Edmond Ernest Johnson, M.I.C., Chemical Engineer, care of United Safe Deposit Company, Limited, United Buildings, Fox Street, Johannesburg, Transvaal, South Africa. Improvements in extracting metals from their solutions, and apparatus therefor.

Claims.—(1.) The process for extracting metals from their solutions which consists in introducing or adding a precipitant to the flowing metal-bearing solution before it enters a mixing vessel or receiver so that the solution serves as the vehicle or carrier for conveying the precipitant into said vessel or receiver and delivering it at or near the bottom of such vessel or receiver, substantially as described. . . . (3.) In apparatus for extracting metals from their solutions, a mixing vessel or receiver for the mixture of metal-bearing solution and precipitant, means for adding the precipitant to the flowing solution before it enters said vessel, and means for delivering said mixture at or near the bottom of said vessel, substantially as described. . . . (5.) Apparatus for extracting metals from their solutions comprising, in combination, a plurality of mixing vessels or receivers, means for adding the precipitant to the flowing solution before it enters the first of such vessels, means for delivering said mixture at or near the bottom of the first of such vessels, and means for delivering the overflow from each vessel to a point at or near the bottom of the next succeeding vessel, substantially as described.
