Title: Improved method of manufacture of capacitors
Inventor: GIRLING DOUGLAS STACEY
IPC: C25F3/04
Filed: 1957-10-01
Abstract: 835,091. Electrolytic etching of aluminium foil; capacitors. STANDARD TELEPHONES & CABLES Ltd. Oct. 1, 1957, No. 30638/57. Drawings to Specification. Classes 37 and 41. Aluminium foil coated on both sides with a dielectric is cathodically etched in an aqueous solution of an alkali metal salt of an organic hydroxy acid to remove the edge portions of the foil. The salt may be sodium or potassium citrate or tartrate and the solution may contain a buffer such as ammonium citrate or tartrate with optionally a cationic or non-ionic wetting agent. The foil may be wound on a former and suspended so that only one edge of the foil is immersed in the solution, cathodic connection being made to the foil through an annular plate in contact with the upper edge of the foil. The etching may be effected by D.C. having a smaller superimposed A.C. component. Etching residues may be removed by cathodic treatment in a weak electrolyte solution of ammonia, citric acid, or ammonium citrate, preferably with the addition of a non-ionic wetting agent. To form capacitors either two such etched coated foils may be wound together with or without additional interleaving layers or an etched coated foil metallized on one surface up to the edge of the dielectric coating from which the foil has been etched but not to the other edge may be wound on itself.

Title: Improvements in or relating to coke ovens and batteries thereof
IPC: C10B5/02
Filed: 1924-12-24
Abstract: 232,173. Koppers Co., (Assignees of Becker, J.). April 10, 1924, [Convention date]. Coke ovens.-Relates to coke ovens of the kind in which the heating-walls are connected in pairs by cross-over ducts as described in Specifications 171,117, 205,459 and 215,306, and comprises arrangements for preventing leakage of gas into the waste gas regenerators, and for securing independent control and uniform heating of the " coke " and " pusher " sides of the battery. The unit section of a battery shown in Fig. 3 consists of three ovens 12, with four heating- walls 11 connected in pairs by the cross-over ducts 26, each heating-wall being in communication with a pair of regenerators 18 for the supply of lean gas and air respectively. The supply arrangements are such that the flow in the two pairs of heating-walls is in opposite directions, i.e. when the flow through the two right-hand walls is clockwise, that in the left-hand walls is anticlockwise, and vice versa. The four inner regenerator chambers, and the two outer pairs therefore operate in different phases, and as producer gas is supplied to the two innermost and the two outermost chambers of the group of eight, an air chamber A is always interposed between a producer-gas chamber P and a waste-gas chamber W. The " coke " and " pusher sides of the battery are fired independently of one another, the regenerators and heating-walls being divided by partitions at about the median vertical plane of the battery, and each half-wall group of flues is further subdivided into three smaller groups, each with its own cross-over duct leading from near the middle of the length of the corresponding horizontal collector flue 25. By this arrangement the flues 25 need not be of large capacity, and are preferably of the wide shallow form shown. The oven may be fired alternatively by rich gas supplied through conduits 30 and nozzles 32. The Specification as open to inspection under Sect. 91 (3) (a) states that the partition between similarly-functioning regenerator chambers may be omitted, and where two or more units are joined up with an additional oven between the units, the partition between the abutting end chambers of adjacent units may similarly be dispensed with. These statements do not appear in the Specification as accepted.

Title: Improvements in or relating to the electrolytic production of zinc from ores or the like
IPC: C25C1/16
Filed: 1924-12-29
Abstract: 249,609. Field, S., Petersson, E. F., Harris, W. E., and Metals Extraction Corporation, Ltd. Dec. 29, 1924. Zinc, depositing. - In a process of the type in which an oxidized zinc ore is leached with sulphuric acid and the solution is purified and electrolyzer, the acid liquor from the electrolytic apparatus being used for leaching the ore, the purification of the zinc sulphate solution is effected in such a way that the silica and iron ore are precipitated while the liquor is in contact with the ore, the precipitates and ore residue being separated together. Preferably the solution is then further treated in a. second chamber to remove remaining impurities such as nickel, preferably by the process described in Specification 162,030. The ore may be roasted in the manner described in Specification 249.764, [Class 1 (iii), Oxides &c.. Metallic] , but if roasting in air is employed a low temperature such as 650‹ C. is preferable so as to produce a minimum quantity of ferrites and manganites. A small quantity of zinc sulphate is produced in the roasting to replace losses of sulphuric acid in the process. The roasted ore is dissolved in hot acid and the last portions of acid are neutralized by materials such as zinc dust, zinc oxide or the zinc hydrate precipitate from the wash liquors as described in Specification 104.697. Whiting is then added in excess with agitation of the hot liquor to precipitate silica. The iron is then oxidized and precipitated bv adding " cell mud," a material containing lead peroxide and manganese peroxide produced at the anode. The solution is then separated by filtration and while still hot is treated in a second chamber to remove copper, cadmium, arsenic, antimony, cobalt and nickel. This mav be effected by treating with mercuric sulphate and zinc powder as described in Specification 162,030. The purified solution is made acid by adding some of the electrolytic cell liquor so as to be suitable for electrolysis. Specifications 138,946, 138.947, 138.948. [all in Class 1 (iii), Oxides &c.. Metallic]; 138,950; 138,954 and 152,752, [both in Class 1 (iii), Oxides &c., Metallic], are also referred to. The final stage, of the purification may be effected as described in any of the prior Specifications mentioned, for instance by slightly acidifying and adding zinc power in excess. Instead of zinc powder other form of zinc may be used, or aluminium or alloys of zinc and aluminium, or other electropositive metals. Specification 11634/13 also is referred to.

Abstract: 1,186,838. Electric motors. BOWMAR INSTRUMENT CORP. 2 July, 1968, No. 31555/68. Heading H2A. To enable the permanent magnet -rotor 46 of a stepping motor for displaying digital data to be rotated through 180 degrees by reverse energization of one of a plurality of stator coils 44, the rotor carries a pair of polepieces 64, 66 at opposite ends of a diameter 68 displaced by an angle #, Fig. 7, of between 5 degrees and 25 degrees from the magnetic axis 62 of .the rotor. In the embodiment shown, five coils 44 are provided each spanning five poles of ten-pole stator and therefore on energization of a coil the magnetic axis 62 aligns itself with the centre one of the associated poles. On de-energization of the coil, the permanent magnet flux seeks the lowest reluctance path to the stator and redistributes itself through the polepieces 64, 66 causing the rotor to rotate slightly until they are aligned with said centre pole. The resulting slight displacement of the magnetic axis enables torque to be exerted on the rotor if the said coil is energized in the reverse direction. The rotor carries a drum 28 on which the digital data is arranged for display through a window 26 in a two-part casing 14, 16.
