Title: Fused electrolyte electrolytic cells
IPC: C25C7/00
Filed: 1961-02-10
Abstract: 913,477. Fused electrolyte electrolytic cells, e.g. for producing Ti. NEW JERSEY ZINC CO. Feb. 10, 1961 [Feb. 19, 1960], No. 5030/61. Class 41. In a fused electrolyte electrolytic cell, e.g. for producing Ti from TiCl 4 , a pervious cathode 8 has an inverted trough-shaped chamber formed by flanges 17 and 10 at its lower end which can be filled with an inert gas such as A or He, and fitted over a flange 12 upstanding from the bottom of the cell to prevent anolyte A and catholyte C from coming into contact in this region. By this means, formation of Ti between the bottom of the cathode and the cell bottom is prevented, the cathode does not become stuck to the cell bottom and can be easily removed for harvesting the Ti. In a modification, the flange 10, instead of projecting inwardly and downwardly, projects outwardly and downwardly. The cathode may be supported out of contact with the cell bottom as shown, or on it. Cl 2  evolved at anode 6 is collected by a cylindrical baffle 15 and removed by an exhaust line 16. The anode 6 may be suspended above the cell bottom as shown or may extend upwardly through it.

Title: Process of producing metals from their oxide ores
IPC: C22B5/00
Filed: 1929-02-15
Abstract: 306,949. Trent Process Corporation, (Assignees of Trent, W. E.). Feb. 26, 1928, [Convention date]. Blast furnaces.-In the smelting of oxide ores a mixture of ore, carbonaceous fuel and flux is heated indirectly by means of rods or tubes passing through a reducing chamber, to a temperature sufficiently high to initiate reduction but below that at which sintering or agglomeration would occur, and the charge is then passed to a smelting-zone heated directly by the combustion of the fuel, the products of combustion being utilized for the indirect heating of the reducing-zone. The apparatus shown in Fig. 1 comprises a reducing chamber 14 superposed on a blast furnace 12 and traversed by tubes 22, through which hot air is passed on its way to the bustle pipe 46 and the tuyeres 50. Blast furnace gas leaves the furnace through ports 64 and is, burnt with hot air from the pipe 46, the products passing around the portions of the tubes between the walls 24, 26. The temperature within the combustion chambers 28 is controlled by returning a part of the waste gases through the pipes 60. The tubes open into end chambers 36 which are so connected to conduits 38, 38<a> that air entering, say, by the left hand conduit 38, passes to alternate chambers 36 at that side, through the tubes to the corresponding chambers at the opposite side. and leaves by the right hand conduit 38<a>. In a modification, Fig. 5, two sets of tubes 22<a> passing across the reducing-chamber are heated by products of combustion, which pass therethrough in opposite directions to headers 36<a> and stacks 86. The temperature in the reducing- chamber may be controlled by passing a portion of the combustion products direct to the stacks through damper-controlled openings 90. In a further modification (Figs. 7 and 8, not shown) the side chambers are partitioned so that the heating-gases pass through groups of tubes connected in series. Specification 316,986 is referred to.

[Class 26] [See also Group XXIX] In a mixing-valve particularly for use where hot and cold water pipes are connected to a mixing chamber 1 for alternative supply to a bath or a shower, one of the outlets is formed as a controlling means so that its position determines the direction of flow. The chamber 1 is formed with a central part 2 having ports 10 therein and wherein is rotatably mounted an extension 4 of the spout 3 also formed with ports 11 controlling the flow of water to the spout. The flow of water to the shower A is controlled by a ported plate 7 fixed to the extension 5 of the spout 3 sliding over a plate 6 fixed to the chamber 1 and formed with ports 16. The arrangement is such that when the ports 10, 11 are in register, the ports in the plates 6, 7 are out of register. A grub-screw 17 in the spout engages a slot in the chamber 1 to limit the movement of the spout to 45‹ either side of the normal position.

Title: Improvements in processes of treating iron ores
IPC: C22B1/08
Filed: 1930-02-17
Abstract: Ferrous and ferric chlorides; ferric oxide; sulphur.--In a modification of the process of the parent Specification, the ferric chloride produced by the chlorinating of ferrous chloride is divided into two portions, the major portion (at least two-thirds) being diverted to the first stage of the process and used as a chlorinating agent for the raw sulphide or oxide ore with removal and condensation of sulphur vapours, while the remainder is oxidized with air to ferric oxide, liberating chlorine for re-use in the second stage, viz. the chlorination into ferric chloride of the ferrous chloride produced from the ore.  The ferric chloride is removed in the form of vapour, split into two streams as above and the cycle repeated.  The condenser used for collecting the sulphur is preferably of the type of a tubular boiler, in which the vapours are contacted with water-cooled surfaces maintained at a temperature corresponding to a steam pressure of 2 to nearly 6 atmospheres.  Specification 355,272 is referred to.

Title: Change speed transmission
IPC: B60W30/18
Filed: 1962-02-12
Abstract: 940,405. Clutch control. BORG-WARNER CORPORATION. Feb. 12, 1962 [Feb. 13, 1961], No. 5354/62. Headings F2C, F2D and F2L. An hydromechanical transmission includes a quick-release fluid pressure operated clutch 13 provided with two belleville spring discs 31, 40, the former of which is effective for clutch engagement and during which it stresses the latter, which then effects quick release upon clutch disengagement. As shown the clutch 13 is mounted between a torque converter 11 and a constant-mesh countershaft change-speed gearbox 12 controlled by a hand lever 50. Pressure liquid for the converter and clutch is supplied by a pump P supplying the converter through regulator valves V1, V2, and the clutch through a solenoid valve 75. The clutch has a single plate 19 engageable between backing and pressure plates 21, 22 by an annular actuator piston 18 bearing against spring disc 31 which also engages the pressure plate 22. The inner periphery of the second spring disc 40 engages the inner wall of the actuator cylinder while its outer periphery is engaged by pressure plate 22. Hence when piston 18 is moved to the right to engage the clutch, spring 31, in moving pressure plate 22, flexes spring 40, which is thus able to effect quick release of the pressure plate upon disengagement of the clutch. A centrifugal pressure relief valve 30 is provided. The solenoid valve 75 is controlled by a push button 51 associated with the gear lever 50, the solenoid 52 being de-energized and the valve 75 moving to the right to admit pressure liquid to the piston 18. An accumulator valve A operates in conjunction with the solenoid valve.

Class 37 In a thermo-couple arrangement for measuring the temperature of a body 1 inside a vessel 2, a thermo-couple probe 5 is sealingly inserted in a hole 3 in the vessel via a member 4 which comprises a compressible bellows 14, the probe normally being held off the body 1 by the action of a spring 21 within the bellows, and the bellows being collapsed by evacuation so that the probe contacts the body when it is desired to make a measurement. Alternatively, the bellows may be collapsed by being enclosed in a structure which is pressurized. The invention is particularly useful in association with vacuum apparatus such as that used in the melting and casting of reactive metal, in which body I is a melting or casting pot.

Abstract: 271,578. Wheeler, G. Feb. 27, 1926. Colour photography; toning. - Photographic silver images are toned with titanium chloride, which may be used in conjunction with a dye.' In the process described, the image layer is first dyed and then immersed in a toning bath of titanium chloride which tones the image yellow, and discharges the dye where the silver deposit is light. The image is bleached, before or after dyeing, as in a bath containing chromic acid and potassium ferricyanide, and then treated with a weak reducing bath, containing for example sodium bisulphite. The toning bath is preferably rendered stable by the addition of citric acid and powdered zinc. The final colour of the image varies from the tint imparted by the dye and the titanium bath in the dense parts, to the yellow tint imparted by the toning bath in the lightest parts. The process may be employed to tone either or both of two colourrecord images carried on opposite sides of a support. Dyes which may be used include basic magenta, induline scarlet, azine scarlet, methylene blue, thionine blue, and turquoise blue.
