two electric furnaces arranged one above the other, the upper furnace serving to produce the metal or the alloy, and the lower furnace serving to refine or to treat with other substances, or reheat said metal or alloy, substantially as described. (2.) The method of electrically treating metals or their alloys, especially iron-ores, for obtaining at will either pig-iron or steel or refined iron in an electric blast-furnace, either with or without a refining-furnace, arranged in the manner set forth, by means of the variations of temperature obtained either in one and the same electric furnace or in different electric furnaces, substantially as described. (3.) In an electric blast-furnace, substantially as set forth, the employment of two groups of electrodes, the electrodes of each group being placed in parallel, and the two groups working at like potential, the number of hearths thus formed being equal to the number of the electrodes, and the hearths being arranged so that the materials to be treated placed between the hearths serve as intermediate conductors between the two groups of electrodes, which allows of a central charging between the electrodes, substantially as described. (4.) In an electric blast-furnace as set forth in claim 2, the arrangement of the electrodes at the vertices or sides of a polygon adapted to the section of a charging-shaft, leaving a free space into which are introduced the substances to be treated, and can be effectively subjected to the action of the hearths without alteration of their composition by the absorption of carbon from the electrodes, so that after a test-batch the composition of the metal can be determined with certainty and kept uniform, substantially as set forth. (5.) In an electric blast-furnace, as set forth, the removal of the reaction-gases through a flue between the two concentric walls of a shaft of masonry containing the materials to be treated, the reheating of said gases at the upper part of the furnace, which part is heated by radiation from the hearth of the electrodes, and the combustion, by passing in air, of the reaction-gases under the sole of the furnace for the purpose of superheating the fusion-zone of the substances treated, and thus augmenting the thermic efficiency of the apparatus, substantially as described. (6.) In an electric blast-furnace, causing a long arc of considerable blast and calorific power to act on the molten mass whilst the metal is being run off, in order to effect a superheating thereof and a volatilisation of the impurities, and combustion and absorption of the carbon, substantially as set forth. (7.) In an electric furnace, the formation or liquefaction, resulting from an increase of temperature momentarily obtained, of certain refractory slags, and the effecting by their discharge the elimination of injurious substances such as titanic acid, substantially as and for the purposes set forth. (8.) In the process for treating ores and metals electrically as described above, the employment of a movable furnace for receiving the metal run off, arranged so as to be very easily placed in circuit during the running-off of the metal from an upper furnace, and which can be moved underneath a number of furnaces of the same battery to receive successively the run-off metal, the placing in circuit of the movable furnace taking place in front of the upper furnaces substantially as described, in order, first, to refine and treat the run-off metal if required; second, to keep melted the metal contained in the electric receptacle, thus admitting of the collection in one receptacle of a very large quantity of metal and consequently of casting very large articles.

No. 14730.—10th April, 1902.—ALBERTO TEODORO DE BARY, of 745, Calle Tucuman, Buenos Aires, Argentine Republic, Merchant. Improved rod for wire fencing.

Claims.—(1.) An improved metallic rod to be used in wire fencing, essentially characterized by having a groove- or corrugation-like shape, provided at the back of both ends with a slot, so that a bifurcation is formed, both of whose arms 4, 4, which are provided with holes 3, 3, may be bent outwards, forming ears, which will tightly hold in position and against the holes the wire passing therethrough, so that the lateral displacement or sliding of the rod is rendered practically impossible, essentially as has been described, with reference to the drawings and for the purpose indicated. (2.) In the construction of wire fencing, and with reference to claim 1, the method of fastening the rod to the wires by bending outwards the bifurcated ends of the rod through which the wire passes, whereby the wire between both arms of the bifurcation will be slightly curved and held down firmly by the said arms, rendering so impossible any displacement of the rod, essentially as described and for the purposes indicated.

No. 14731.—10th April, 1902.—ROBERT OXLADE, of 177, George Street, Redfern, near Sydney, New South Wales, Electrical Engineer, and WILLIAM JOSEPH WHITE RICHARDSON, of Shaw and Belgrave Streets, Petersham, near Sydney aforesaid, Electrician. Improvements in audible electric telegraphy.

Claims.—(1.) In electric telegraphy, transmitting signals to a telephone by means of an induced current between stations by the arbitrary breaking of a local primary current of two different strengths in a transformer from which such induced current is derived, substantially as described and explained. (2.) In electric telegraphy, interposing a transformer between a sending-key for opening by two impulses a closed circuit at one station and a telephone receiver at the other, so as to transmit signals between such stations by a secondary or induced current in the line wire, substantially as described and explained. (3.) In electric telegraphy, having an induced current in the line wire conveying signals caused by the breaking or opening of a closed local primary circuit of two different strengths, devices for short-circuiting the secondary coils, and a transformer for inducing said current in the line wire, substantially as described and explained. (4.) The combination and arrangement, with the line wire of an audible electric-telegraph system carrying an induced current, of battery such as D having a part-connection such as X, or having a smaller battery and similar connection of a sending-key such as E having connections such as Ex, E1, E2, and E3, a transformer or induction coil such as B, a switch such as C having arm such as Cx, and contacts such as C1, C3, and C4, and a telephone receiver such as A with or without a resonator, substantially as described and explained, and as illustrated in Figs. 1 and 2 of the drawings.

No. 14733.—10th April, 1902.—WILLIAM ERNEST HUGHES, of Queen's Chambers, Wellington, New Zealand, Patent Agent (nominee of the Baron Cigarette-machine Company, Limited, of 4 to 6, St. James Place, Aldgate, London, England, Manufacturers—the assignees of Louis Bernhard Baron, of 4 to 6, St. James Place, Aldgate, London, aforesaid, Engineer, and Edward Thomas Pollard, of 126, Queen's Road, Everton, Liverpool, England, Engineer). Improvements in machines for packing cigarettes, cigarette-mouthpieces, and like articles.

Extract from Specification.—This invention relates to improvements in machinery for forming the slide cases or packets for packing therein cigarettes, cigars, or the like, together with a suitable number of mouthpieces for same if desired, the object being to provide a machine which will form the slide from a series of paper or pasteboard blanks presented to it in a continuous strip, fill the same with cigarettes, for example, insert if desired a suitable number of mouthpieces at the side or sides of same, and finally insert the filled slide case in an outer rectangular case or cover.
