Title: Improvements in and relating to Methods of Extracting Zinc and other Metals from Ores and the like.
Inventor: MARKS GEORGE CROYDON
Filed: 1902-12-31
Granted: 1903-02-26
Abstract: 28,925. Marks, G. C., [Waring Chemical Co.]. Dec. 31. Cadmium salts; sulphides; sulphuretted hydrogen; sulphurous acid; zinc sulphides.-Relates to the treatment of zinc ores to obtain zinc sulphide by precipitating from solution by means of sulphuretted hydrogen. The ores are (a) lixiviated with a dilute acid or acid mine water either in tanks &c., or the lixiviant may be run through the ore bed in the mine, in sit¹, and subsequently pumped up. The solvent should contain a small amount of iron sulphate. (b) The solution thus obtained is then treated with a small quantity of sulphuretted hydrogen, or zinc sulphide, in order to precipitate sulphides of the copper group. (c) The solution is then subjected in closed vessels to the action of a measured quantity of sulphuretted hydrogen, corresponding to the amount of zinc in solution, and heated. The zinc is precipitated as sulphide, and the liquid is then used again as a lixiviant. The acid may be restored if necessary by subjecting to the action of sulphurous acid gases from roasting furnaces and exposing to the air. The residue from (a) is then roasted, or it may be treated to produce the sulphuretted hydrogen and then smelted to obtain metals such as silver, lead, gold. The residue obtained in (b) is treated to remove zinc sulphide by agitating with a copper solution. The residue is boiled with dilute sulphuric acid to dissolve out cadmium, the last portions of zinc leaving the copper and silver in the residue. The solution may be treated with sulphuretted hydrogen to obtain "cadmium " yellow." The residue may be smelted and electrolysed. In the case of oxidized ores, the sulphuretted hydrogen may be obtained from barium sulphide, produced by reducing the sulphate, or from calcium sulphide, by passing lime kiln gases over the sulphides, or the carbonic acid may be obtained by passing roasted gases into a solution of sodium sulphite and acting upon barium carbonate with the solution so obtained.

Granted: 1903-03-26
Abstract: 2560. Wheelwright, C. S., and Fiske, J. T. Feb. 3. Strainers for wood pulp, the filling-material used for treating paper cloth &c. The pulp &c. is placed in a steam-jacketed vat A provided with a perforated false bottom C and a central cylinder D containing a lifting-screw J, which lifts the pulp to a perforated portion a of the cylinder D and ultimately to a trough L fitted with a discharge spout. The perforated part a of the cylinder D is surrounded with a vacuum chamber F, from which liquid is withdrawn by a pump H and discharged into a tank G. The pulp in the vat A is supplied to the lower end of the cylinder D by a pair of propeller blades M, which revolve in the opposite direction to the screw J. Beneath the perforated bottom C is a chamber containing heating-pipes and connected by a pump H<1> with the receptacle G; J<2> is an inverted cone by which the capacity of the cylinder D is restricted at this part, to assist in the squeezing of the liquid from the solid part of the pulp ; and D<2> is a conical and projecting guide to assist in the feeding of the pulp to the lower end of the cylinder. Instead of using perforated metal only as the filtering or straining medium, a layer of felt may be placed between two perforated metal plates.

Granted: 1904-01-07
Abstract: 25,364. Wiseman, Z. Nov. 20. Stoppers; refilling, preventing.-Relates to a non-refillable bottle which can be emptied from either the upper or the lower end. Fig. 2 shows in section a bottle adapted to be emptied at the lower end. The interior of the bottle is formed with a series of ratchet-faced corrugations A'.

Abstract: 18,364. Verdier, J., and Teulon, P. Sept. 2, A.D. 1903, [date applied for under Patents Act, A.D. 1901]. Gas retorts.-Vertical retorts, for the continuous production of gas, are provided at the top with a nozzle d to which is connected the feeding-device f, the ascension pipe branch e, and a branch g which admits of the coal in the upper part of the retort being stirred. The feeding device consists of a rotating plug provided with a cavity m. The rotation of the plug is facilitated by a piece q having a bevelled edge r. A similar device is arranged at the bottom of the retort for discharging the coke, the piece q being provided with a serrated edge r for breaking up the coke. The are n o is less than the arc op, so that air cannot enter the retort. A plate u may be fixed so as to prevent the discharge of coke and the consequent emptying of the retort should the feeding be momentarily stopped. An elevator feeds a conveyer with flat boards V which discharge the coal into the hoppers w, and on their return remove the coke from the lower part of the retort. The feeding and discharging devices are driven by flexible chains or similar arrangements from a longitudinal shaft. A branch i at the bottom of the retort permits a rake to be inserted while the retort is at work.

Abstract: 20,184. Thompson, W. P., [Matricardi, V.]. Sept. 19. Smoke-consuming; baffles.-To effect combustion of smoke and gases in steam-generator and other furnaces, refractory tubes, rods, and baffles, which are made incandescent by the heat of the furnace, are arranged in the path of the furnace gases. Fig. 1 shows the back part of a marine boiler having refractory perforated tubes 5, closed at their outer ends, inserted in the boiler tubes, to which the smoke and gases escape by way of the perforations in the refractory tubes 5. The lower rows of boiler tubes may be provided with straight or helical rods 8 to prevent dust from being carried off and to promote combustion. These rods may be supported by refractory bars or rods 9. Air for combustion is supplied by way of a door in the firebridge. The smoke tubes of locomotive and portable - engine boilers may be provided, as shown in Fig. 2, with refractory rods such as are shown in Figs. 18, 19, and 20, each rod carrying at its outer end a thin refractory plate. A water-tube boiler in which a row of water tubes is replaced by smoke-consuming tubes perforated and corrugated or otherwise formed, is shown in Fig. 3. Fig. 23 shows a series of perforated refractory tubes or baffles 2 placed between the water tubes 1 of a boiler ; they are made in two parts to facilitate their insertion. The furnace flues of Cornish boilers may be provided with refractory perforated tubes as shown in Fig. 4. The perforated refractory tubes described above may be replaced by either of the modifications shown in Figs. 6,7, 8, and 21,and by various other modifications described in the Specification, all of which are in the form of a perforated tube closed at the outer end. The tubes may all be corrugated on their interior surface.

Tenoning and dovetailing. - The table r of a machine for cutting dovetails of various sizes and shapes is transversely reciprocated by a shaft u, which is provided with a crank-disc and radially adjustable crank -pin t coupled by a connecting-rod to a lug on the table. The shaft may be driven by the hand-wheel 16, or by power through bevel gearing v, w and worm gearing from the driving-shaft b ; the loose wormwheel e is clutched to its shaft f by means of a clutch 9, 10, the part 10 of which slides on a feather on the shaft t f, and is operated by means of a foot-lever. The slide z, to which the two pieces of wood to be dovetailed simultaneously are fixed by screws 24, 25, is longitudinally traversed by a rack 2 and spring-pressed pawl 3 which may be double-ended ; or two pawls may be provided to vary the movement of the slide by half a rack tooth. The pawl is pivoted on a block 4 which is reciprocated through a connecting-rod 5, a radially adjustable crank-pin 6 on a disc 7 attached to a vertical shaft q, a universal coupling o, telescoping shafts n, m, and a second universal coupling from a shaft i, which is itself driven through spur gearing h from the shaft f. The slide z may be frictionally held in position by a spring-pressed pawl 17, held out of action by a lever 19 actuated by a cam 20 on the shaft q in such a manner that the pawl is disengaged at the moment the pawl 3 come into action. The cutter 30 is clamped in the end of a shaft 21, working in bearings in a frame 31 vertically adjustable by a screw 32 or other means, and rotated by a belt passing around the drum 22. Fig. 7 shows an inverted plan of two pieces of wood in the cutting positions, which are fitted together by fixing the rounded projections 26 in the hollows 27. The Provisional Specification' also states that, instead of a friction retaining- device 17, a retaining-pawl engaging the rack may be employed, and a spring or weight to hold the slide with the rack pressed against the pawl.
