Title: Improvements in Methods of and Apparatus for Refining Tin Electrolytically, particularly for Extracting Pure Tin from Alloys, Wastages, Residues, and the like, with the Extraction of the Foreign Metals.
Inventor: STEINER OTTO
Filed: 1907-05-02
Granted: 1907-08-22
Abstract: 10,230. Steiner, O. Feb. 1, [date applied for under Patents Act, 1901]. Electrodes; electrolytes; polarization, preventing; tin, refining.-Consists of improvements on the invention described in Specification No. 297, A.D. 1895, in which tin is refined by electrolysis in an alkaline sulphur solution at 90‹ C. with a current density of 1 ampere per square decimetre, antimony and arsenic which are deposited with the tin being removed by a second electrolysis in a hydrochloric acid sodium phosphate solution. According to the invention, the cathodes consist of pure tin or tin-plate sheets ; the tension between the electrodes is kept less than 0 2 volt by adjusting the concentration of the solution and the current strength ; about 1 per cent of the weight of the electrolyte of flowers of sulphur as depolarizer is added to the electrolyte before the suspension of fresh anodes ; the anode mud is not disturbed during the electrolysis ; and good contacts are secured by using homogeneous tinned conducting- bars soldered either directly or through strips &c. to the electrodes. The electrolyte is heated by steam by means of double bottoms or a coil at the bottom. In changing the anodes, the electrolyte is drawn off slowly by a siphon above the anode mud, after which the electrodes and the mud are successively removed. New electrodes are then inserted, the electrolyte is poured in, and flowers of sulphur- and enough sodium sulphide to keep up the strength of the solution are added.

Granted: 1908-07-23
Abstract: 19,790. Simonides, B. Sept. 14, 1906, [date applied for under Patents Act, 1901]. Float valves; annular valves; tubular valves; actuating valves and cocks. - In a gravity-feed apparatus of the kind in which a receiver 1 mounted above the boiler contains a float 7 operating a valve 9 in the feed-pipe, the steam - pipe connexion 5 terminating in the boiler at the normal water level surrounds the water pipe connexion 4. In the apparatus shown, the valve 9 is an annular disk valve which is lifted and pressed against its seating ring 21 as the float rises to the top of the receiver. The valve is provided with auxiliary relief valves 10, which allow water to pass from the feed-pipe into the receiver before the main valve opens. A valve 12 at the top of the water pipe 4 prevents the steam from blowing through the receiver back into the boiler. In a modification, the valve 9 is a sliding tubular valve, and in another modification, it is an equilibrium valve. The Specification, in the original form, as published under the Act of 1901, describes a further modification in which the valve is operated by a rod placed in the receiver and expanding and contracting according as the receiver contains steam or water. This subject matter does not appear in the Complete Specification as accepted.

Granted: 1908-08-06
Abstract: 27,443. Jones, A. O. Dec. 12. Coke ovens ; regenerators; charging.-In regenerative vertical or horizontal coke ovens of the type in which there is no reversal of flow in the oven, the regenerative tunnels are placed outside the body of the structure and parallel to the front wall thereof, the air supply and exhaust flues being adjacent and controlled by suitable valves. The invention as applied to a vertical oven, such as described in Specification No. 11,660, A.D. 1906, [Abridgment Class Fuel, Manufacture of], is illustrated in Fig. 1. When the valve 17 is in the position shown, air passes from the tunnel 21 through passages 14, 11, 10 to the vertical flue 7, which is in communication with a number of horizontal flues 4 passing round the oven. On leaving the flue 7, the air is mixed with gas supplied through burners 6, the products of combustion passing round the ovens to a vertical flue 5, and then through passages 13,15, to the tunnel 22. When the valve 17 is reversed, air passes through the tunnel 22 and passages 15, 12, 10 to the vertical flue 7, while the combustion products pass from the flue 5 through passages 13, 14 to the tunnel 21. The invention may be applied to an horizontal oven, such as described in Specification No. 17,137, A.D. 1907, [Abridgment Class Fuel, Manufacture of]. Vertical ovens are charged from a hopper wagon the outlet of which is the full size of the retort.

Abstract: 15,742. Siemens & Halske Akt.-Ges. Oct. 8, 1907, [date applied for under Section 91 of Patents &c. Act, 1907]. Cut-outs; switches.-In a time-limit device for opening or closing electric circuits on the occurrence of abnormal current, (1) the spring opposing the movement of the armature disk or other movable part is arranged with a cam or equivalent device so as to produce a constant or predetermined opposing force, (2) the inducing or field magnet is adjustably mounted so as to obtain different degrees of regulation, (3) one of the contacts is mounted adjustably round the spindle of the armature, and (4) the relay may be associated with a quick-acting solenoid switch operative on a heavy overload. In the form shown in Fig. 1, a disk armature a is made to rotate by the screened poles of a field magnet c carrying one or more windings energized by the voltage or current to be controlled. The disk drives through toothed gearing a wheel f, carrying a pin o adapted to open or close contacts p. On the shaft of the wheel f is fixed a cam or cams g attached to the end of a spring i, which is fastened at the other end to a fixed point k. The arrangement of the cam and spring is preferably such that the rotary movement of the wheel f slightly increases as it turns further round. To adjust to predetermined load limits, the field magnet c is turned by a wormgear m around a pivot l; or it may be rotated about a pivotal line through the centre of the poles. An adjustable damping-magnet r may also be provided. To vary the timing of the relay, the contacts p, mounted as shown in Fig. 5 co-axially with the spindle of the wheel, are set so as to give a longer or shorter path for the pin o to travel. In a modified form of the relay, shown in Fig. 3, the armature disk a winds a cord 2 carried over a cam 3 attached to the retracting-spring 5. The positions of the disk and drum may be interchanged, and two cams may be employed to transmit the motion.

Abstract: 26,322. Adair, W. Dec. 5. Lifting-jacks.-Lifting-jacks for raising vehicles are provided with means for rapid adjustment of the crutch pillar, ratchet mechanism for raising and lowering the load step-by-step, means for folding-up the jack into a narrow compass, and means for pushing the jack into position under the car. - For rapid adjustment, a lever B, Fig. 3, which is linked to the crutch pillar; is rocked on the fixed bracket D by inserting a removable handle into a socket B'. By pushing the handle through the socket until it abuts against a laterallvprojecting plate on the stand, the jack can be moved bodily to position it under the vehicle. Other sockets may be formed at the base of the jack for this purpose. The rapid adjusting- mechanism may have a pin-and-slot connexion between the levers B, B<5>. The load is raised step by step by suitable pawl mechanism (not shown) when the handle is inserted in the socket G and the bracket attached thereto is rocked about the pivot G<2>. The handle is restored by the spring H afrer each depression. The load is retained in the raised position by a spring pawl Z which can be withdrawn by a pivoted lever carrying a third handle socket M, to lower the load rapidly or step by step. In a modified form two pawls, levers, and sockets are mounted side by side for alternate operation. To enable the jack to be folded into a narrow compass, the parts of the base-plate, projecting beyond the standard, and the projecting bracket D are hinged so that they can be turned into positions parallel to the standard. Fig. 14 shows a form of crutch having pivoted members X which are retained in an upright position by springs until they engage the axle of the car.
