Granted: 1904-10-05
Abstract: 21,392. Schulze, H. Oct. 5. Barium oxide is obtained in a porous condition by subjecting the carbonate, sulphate, fused oxide, hydrate, carbide, or their derivatives, mixed with carbon or otherwise, and with a compound of an alkaline earth (usually barium nitrate), to the direct or indirect action of radiated heat in an airtight chamber. In the case of carbon compounds of barium, the admixture of the alkaline-earth compound may be omitted. The fused barium oxide is obtained by heating in the electric arc or by heat radiated from the latter, either barium carbonate, or barium sulphate mixed with carbon, with carbon and barium chloride, or with both barium chloride and sulphide. One form of electric furnace, shown in Fig. 1, has carbon electrodes c, d situated within a chamber, the sides a, h, g of which are made of firebrick or other fireproof material. The dry or moist barium mass b is introduced by means of a hopper, and the decomposition gases are discharged through a pipe f. In order to ensure uniform heating of the mass, the chamber or the electrodes is or are capable of vertical movement. A modification is described in which the electric arc is replaced by a conductor of high resistance rendered incandescent by the electric current, and gas is used in some cases as the heating-agent.

Abstract: 22,194. Brewster, M. B. Oct. 31. Mechanical stoking.-In a fuel-feeding device for furnaces, the fuel falls from a hopper into a steamactuated reciprocating measuring-device which discharges into a shoot leading to a table arranged inside the fire-door, whereon the fuel is deposited, and whence it is finally distributed over the firebed by a series of steam jets. Fuel is fed by a conveyer 15, Fig. 1, into the hopper 5, from which it falls into a receptable 12 within the reciprocating ram 11. The latter is operated by steam pressure acting upon a piston in the cylinder 17, the piston-rod being connected to a lever 21 keyed to a transverse shaft 22. This shaft projects through the sides of the hopper and has keyed to its ends arms 23 which engage with trunnions 24 on the sides of the ram 11. As the ram is moved from below the hopper, the receptacle 12 communicates with a shoot 16 mounted on the firedoor 3. The fuel passes down the shoot and is deposited upon the table 55, where it is subjected to the action of steam issuing from a series of nozzles 53, 54 to distribute it over the fire-bed. The nozzles are supplied with the exhaust steam from the cylinder 17, and only at such times as the fuel is fed to the table 55. To start the stoker, steam is admitted to the cylinder 17 by manipulating the piston slide valve. The latter is reciprocated by a cam mounted on the shaft 42, at the end of which is a ratchet-wheel 43. This wheel is rotated by a pawl 45 upon the lever 44, which is connected to a suitable motor or other operating- means (not shown).
