No. 19478.—16th May, 1905.—EDWARD NEEDHAM WATERS, a member of the firm of Edward Waters and Son, Patent Attorneys, of No. 414-418, Collins Street, Melbourne, Victoria, Australia (nominee of the Edison Ore-milling Syndicate, Limited, of Fitzalan House, Arundel Street, Strand, London, England—assignees of Thomas Alva Edison, of Llewellyn Park, New Jersey, United States of America, Electrical Engineer). Improvements in or relating to magnetic separators and electro-magnets applicable for use therein.

Extracts from Specification.—In carrying the first part of the invention into effect one or more sets of magnetic separators are employed, each being in the form of an ordinary double-coil electro-magnet with extended tapering poles one of which slightly overlaps the other to form a relatively narrow gap between them, and to the upper face of the overlapping pole is delivered a continuous but thin stream of the particles moving at as slow a rate as practicable, whereby the non-magnetic particles will be permitted to flow down the polar face and fall off therefrom at one side of a separating-board, while the magnetic particles will by the lines of magnetic force be attracted towards the other pole and will fall on the other side of said separating-board. Preferably a number, as stated, of such separators are used, divided into two series, in the first of which the particles rejected by the first separating-device will be subjected to the succeeding separators, whereby a very rough concentration will be secured, while in the second set the material concentrated by the first separator will be subjected to the succeeding separators to secure a concentrated product of high percentage. . . . The improved magnet consists of a body 22 of approximately horse-shoe form, and comprising an upper portion 23, a lower portion 24, and a vertical or middle portion, the last named of which is encircled by and concealed within the necessary energizing coil 2. The end face of the upper portion 23 is inclined in relation to the axis of the coil 2, and that of lower portion 24 is parallel with the said axis, the former face overhanging or projecting more forwardly than the latter face, all as shown most clearly in Fig. 5. To the inclined face of the upper portion 23 the upper pole-piece 3 is secured by two bolts 25, this pole-piece being formed of a flat plate of iron or soft steel, and to the vertical face of the lower portion 24 the lower pole-piece 4 is secured by two bolts 26, this said pole-piece being formed of iron or soft steel of angle-bar section. The respective meeting-faces of the pole-piece 3 and portion 23 and of the pole-piece 4 and portion 24 are truly planed and surfaced so as to provide the best contacts possible between the said parts.

No. 19483.—17th May, 1905.—WALTER B. DEVEREUX, of Glenwood Springs, Colorado, United States of America, Mining Engineer. Agitating-devices.

Claims.—(1.) The combination in a metallurgical apparatus of a tank and a plurality of propellers arranged to rotate on vertical shafts within the tank above the level to which the solid material of the charge will settle when the propellers are at rest. (2.) The combination in a metallurgical apparatus of a tank, means for decanting the liquid contents, and a plurality of propellers each arranged to rotate on a vertical shaft within the tank above the level to which the solid material of the charge will settle when the propeller is at rest.

No. 19484.—17th May, 1905.—DR. AUGUST VOELKER, of No. 56, Unter den Linden, Berlin, German Empire, Electro-chemist. Improvements in and connected with heating by electricity.

Claims.—(1.) A method of manufacturing an electric incandescent body consisting in reducing carbonaceous material to particles or grains, of from one to seven millimetres in diameter, and in then dividing the material into main groups of which the first consists, for example, only of grains of one millimetre diameter, the second of grains of two millimetres diameter, and so on, each of these groups, for the purpose of obtaining a highly graduated series of sub-groups, being varied by the addition of substances which increase or diminish the conductivity of the group, substantially as described. (2.) The method of heating articles by enclosing them in a jacket composed of masses of the kind described in the preceding claiming clause so graded that the electric current can only flow through those portions thereof which are in direct contact with the surface of the article to be heated, the remaining portions of the jacket serving mainly as a heat insulator and for collecting wandering current-waves, substantially as described.

No. 19488.—18th May, 1905.—GEORGE STACY, of No. 23, Ventor Avenue, Perth, Western Australia, Journalist. An improved voting-machine.

Extracts from Specification.—Each machine may consist of any number of units, each unit being mainly comprised of the voting or pull bar with its vote-registering device in conjunction with which as adjuncts or auxiliaries there are four interlocking-devices or counter-checks whose duty and purpose is to prevent fraud, errors, or omissions on the part of voters or other persons in the use of the machine. Such interlocking-devices may now be briefly summarised. (1.) A locking-device which is controlled and operated by the admission-door attached to the machine, as such door upon closing withdraws a bolt which allows of the use of any of the voting-bars. (2.) A dropper movement which engages with serrations formed on the top face of the voting-bar for locking such bar after a vote is recorded until such time as the voter leaves the booth and opens the control door, so allowing the voting-bar to resume its normal position. (3.) The interdependent set of horizontal locking-devices whose duty it is to lock each and every of the unused or idle voting-bars on the same horizontal row so that not more than one candidate can be voted for when only one candidate is required to be returned. (4.) A vertical locking-device for use in direct voting when two or more candidates are to be elected and for use in preferential elections, and which device is operated by a lock and inclined plane whereby each and every of the idle voting-bars on such same vertical row are locked so that a further vote cannot be given for the same candidate.

No. 19494.—18th May, 1905.—ARTHUR JOHN LEWIS ECKERSLEY, of 214, Queen Street, Melbourne, Victoria, Australia, Chemist. Improvements relating to syrup-gauges for aerated-water bottling-machines.

Claims.—(1.) In syrup-gauges for aerated-water bottling-machines, a pump mounted on a rocking lever and having a piston operated alternately by a spring and an inclined cam bar, an inlet-valve connected to the syrup-supply, and an outlet-valve in communication with the filling head, combined and arranged substantially as and for the purposes set forth. (2.) In syrup-gauges for aerated-water bottling-machines, a pump having a spring piston adapted to be operated by a cam bar inclined outwardly at one end, horizontal studs marked with graduations on said bar extending through holes in the bracket on the standard, vertical wing-nuts engaging the shank of said studs, and an adjustable screw-bolt extending through said bracket and engaging the cam bar, substantially as and for the purpose set forth.
