Title: Improved Process and Apparatus for the Smelting of Steel and other Metals Direct from their Ores by Aid of Heat and Electiricity.
Inventor: THOMPSON WILLIAM PHILLIPS
Filed: 1901-12-27
Granted: 1902-12-24
Abstract: 26,470. Thompson, W. P., [Syndicat de l'Acier Gerard]. Dec. 27. Electric furnaces.-Resistance heating is used for melting and refining iron, steel, chromium, nickel, tungsten, and other metals in the extraction of these directly from their ores. The apparatus used includes a smelting furnace H, and a Siemens- Martin furnace F, which communicates with the furnace H by means of apertures P', P<2>, <p3> and a siphon channel M. In the lower part of the furnace H are two electrodes L', L<2>, a dam D over which the slag flows, and a clearing hole fitted with a block O. A pipe E, provided with a slide R', connects the furnace H to a gas generator G, which is fitted with a slide R'. The apparatus is first heated by means of gas from the generator, the slide R<2> being shut, and the slide R' and charging cone C opened. Granulated ores, carbon, and fluxes are then charged into the furnace H, and the smelting is effected at a comparatively low temperature, the slide R<1> being entirely or partially closed and the slide R' opened by degrees, while a flow of gas is produced through the furnaces by means of an injector J. When the ores have been reduced, but the metal is in a spongy state, a large current is passed through it, between the electrodes L', L<2> ; the reduced metal is thus melted and descends through the passage M to the hearth of the furnace F. The operations are continued until the furnace F contains a sufficient charge, when a positive electrode s<1> is immersed in the bath, conveying a high-pressure current thereto, the corresponding negative electrode being fixed in the hearth at s<2>. The current causes the metal to be thrown up in small drops, and thus exposed for refining by the air in the furnace. The electrodes may be of metal, or of a mixture of the oxide and the reducing-materials. One or more refining furnaces F may be used in combination with one or more smelting furnaces.

Title: Improvements in Systems of Electrical Distribution
Inventor: CAROLAN EDGAR ALFRED
Filed: 1902-11-25
Granted: 1903-09-24
Abstract: 25,904. Carolan, E. A., [General Electric Co.]. Nov. 25. Dynamos and motors combined as transformers; rotary transformers; field magnets ; motors, controlling. -Relates to devices for increasing the number of phases of an alternating current, more especially in systems in which it is desired to supply multiphase translating-devices from single-phase mains, and consists in providing a number of sources of electromotive force, preferably counter electromotive force, dephased from one another by a definite and fixed amount. These sources are preferably connected in series across each pair of the mains carrying the current the number of phases of which is to be increased. As shown in Fig. 1, a single-phase generator A feeds a pair of mains 8, 9 through a step-up transformer T. Connected to these mains are other transformers T', T<2>, having, if desired, lamps L, L<3> in multiple with the secondary mains. The mains 4, 5 are connected to the primary windings B, B<1> of a pair of synchronous dynamo electric machines connected in 'series across the lines. These machines are preferably motors, but may receive external power. The secondary members C, C<1> are rigidly coupled together, for example, by mounting upon the same shaft S, so that the electromotive force or counter electromotive force of the two machines are dephased. The members C, C' are shown excited by a direct-current machine E, and controlled by adjustable resistances R<1>, R<2> . Beyond the machine, in the wires 4, 5, 6 connected to the outer terminals and to a point intermediate the windings, two-phase currents flow. Other devices are also shown, namely, a three-phase motor M' led through the transformer T<3>, a two-phase induction motor M<3>, a monocyclic synchronous motor M<4>, having a separate exciter and rheostat, high-voltage lamp L', and low-voltage lamps L". The angle between the two auxiliary sources of electromotive force is here 90 degrees ; if they are arranged to be 120 degrees, a three-phase system would result, while, by varying the number and phase angles, any preferred system is obtainable. In the form shown in Fig. 2, the source of electromotive force is a transformer T<4> connected to a single-phase system. Two angularly-disposed primary windings B', B<3> (preferably on a single core), are connected in series, while the secondary member C' is shown as a short-circuited motor, but may be similar to C or C<1> in Fig. 2. To start the armature, a condenser K and switch S are shown. When started, the device will run as a single - phase induction motor. The counter electromotive forces of the two windings B', B<3> are dephased, and act as do the electromotive forces in B, B<1>, Fig. 1.

Title: Potash Leaching Apparatus for Raw Wool.
Inventor: BERNHARDT ERNST FRIEDRICH
Filed: 1904-05-21
Granted: 1905-03-30
Abstract: 11,736. Bernhardt, E. F. May 21. Washing.-In an apparatus for leaching raw wool, the wool is carried through the machine by rakes while water, which at the entrance is considerably charged with extracted potash, is sprayed over it. The leaching-liquor becomes weaker and weaker as the wool progresses. The reservoirs 13 to 18 are filled with water until it reaches the outlets shown. The wool, which may be short and thin, enters a shaft having as its front wall a grating 7 through which pass the easily-removable rakes 4 mounted on two endless travelling chains 3. The attached levers 5 have rollers which run on guide-rails 6. The rakes being thrown into gear to carry the wool forward, the pump 19 is started so as to spray the wool. The liquor drips through the perforated channel 1 back into the reservoir 13, and this happens for each reservoir as, when the wool reaches them, each pump 20 to 24 is successively started. The float 11 is adjusted to open the valve 10 when the density of the liquor in the reservoir 13 reaches a predetermined value, causing a flow of clean water between the pairs of rollers 8, 9. There follows, consequently, an overflow from reservoir to reservoir until the density of the liquor in the reservoir 13 is reduced. The outflow at 25 is sufficiently concentrated to be advantageously evaporated to extract the potash. The pairs of squeezing-rollers 8, 9 have a greater surface speed than the speed of the rakes, although their respective speeds are the same when the endless band over the lower rollers is used. If the band be dispensed with by bringing the pairs of rollers closer together, the second pair 9 may be run at a greater speed than the first. To avoid corrosion by the leaching-liquor, the forks are covered with enamel, and the channel 1 and float 11 are either made of vulcanized india-rubber or protected by enamel.
