Title: Improvements in electrodes for secondary cells, especially those having alkaline electrolytes
IPC: H01M4/29
Filed: 1936-12-24
Abstract: 487,607. Batteries; electrodeposition of hydroxides and basic salts. JOHNSON, G. W. (I. G. Farbenindustrie Akt.-Ges.) Dec. 24, 1936, No. 35335. [Classes 41 and 53] Accumulator electrodes comprising porous metal supports containing active material in the form of hydroxides or basic salts are made by introducing the active material into the pores of the supports by cathodic polarization. In one method the supports are subjected to electrolysis in a solution of the nitrate of the metal. Other salts may be used if oxidizing substances such as hydrogen peroxide or hypochlorites are added. Substances may be added to increase the conductivity of the solution, such as salts of magnesium or aluminium or of the alkali or alkaline earth metals. In another method the porous metal supports are first impregnated with the electrolyte of nitrates &c. and then subjected to electrolysis in a solution of the sulphate or hydroxide of an alkali metal. In an example, a porous nickel plate made by sintering nickel powder which has been obtained from nickel carbonyl is impregnated with a solution of nickel nitrate and then subjected to cathodic polarization in a thirty per cent solution of caustic soda at 70‹ C. The plate is then washed and dried and the process repeated several times. In another example, a porous iron plate is impregnated with a solution of cadmium nitrate and subjected to electrolysis in a solution of caustic potash.

Title: Discharge machining apparatus
IPC: B23H1/02
Filed: 1960-10-17
Abstract: 942,209. Machining by spark erosion. K. INOUE. Oct. 17, 1960 [Oct. 29, 1959; Nov. 21, 1959], No. 35465/60. Heading B3V. [Also in Division G3] In spark machining apparatus in which the discharge gap is varied in dependence upon the gap voltage and the discharge current is varied in dependence upon the mean resistance of the gap, increase of the discharge current is delayed. A condenser 3, Fig. 2, discharging across the gap between an electrode 1 and a workpiece 2 is charged from an A.C. supply through a saturable reactor 6 and a rectifier 5. Connected across the gap is a control winding 7 which during normal working is energized to saturate the reactor. When a short circuit occurs across the gap, a D.C. source 13 in a circuit including a rectifier 11 energizes the control winding 7 to de-saturate the reactor 6 and to block the A.C. supply. Meanwhile the electrode 1 is separated from the workpiece 2 until the short circuit is removed and is then fed towards the workpiece. The re-saturation of the control winding 7 is delayed by an inductance 9. As shown, the motor 21 driving the electrode is in series with a resistance 23 and a D.C. source 22 having a voltage equal and opposed to the normal gap voltage. When the gap is short circuited the source 22 drives the motor 21 to lift the electrode 1 until the short circuit is removed. When the discharge current ceases to flow the control windings of saturable reactors 28, 28a are desaturated so that an A.C. input is fed through a rectifier 27 to produce a voltage across the resistance 23 so that the motor lowers the electrode 1, the input to the rectifier 27 being shunted through the reactors 28, 28a when the discharge current again flows across the gap. In a modification, Fig. 3, during discharge an oscillatory discharge is produced if necessary with the aid of a resonant circuit shown in dotted lines, and serves to charge a condenser 31 through a rectifier 32. The control winding 7 is energized by discharge from the condenser 31. When a short circuit occurs the condenser 31 is no longer charged and the reactor 6 blocks the supply. The condenser 31 also functions to delay the rise in discharge current after the short circuit has been removed.

Abstract: 904,453. Coating with metals. YAWATA IRON & STEEL CO. Ltd. Nov. 5, 1958, No. 35602/58. Class 82 (2). In a continuous process of coating ferrous metal with aluminium or aluminium base alloys, the ferrous metal is passed from a protective atmosphere through a bath of molten bismuth, sodium or potassium and then through a bath of the molten aluminium or aluminium alloy. As shown in Figs. 1 and 2 steel strip 1a passes through an oxidizing furnace 6 maintained at 400‹ to 700‹ C. and then through a reducing and annealing furnace 7a/7b through which a reducing gas flows concurrently to the strip, the furnace being maintained at 650‹ to 970‹ C. The furnace terminates in a hood 8 leading into a pot 9 which contains the molten aluminium 13 on the surface of which floats the molten bismuth, sodium or potassium 25 which is confined by the partition 23 and enclosed by an extension of the hood 8. The strip passes through the molten metal 25 and the molten aluminium 13 and emerges via a controlled cooling chamber 15a in which a suitable gas atmosphere may be maintained. The cooled strip may be heat treated in a furnace 17 under a reducing or neutral atmosphere and after optional treatment in an electrochemical cell 18, the strip is dried in chamber 20. The aluminium bath is protected from oxidation by an asbestos sheet floating on the surface or by an inert gas cover and the coated strip as it emerges from the bath may also be sprayed with a neutral or reducing gas.

Abstract: 394,973. Can-openers. USBECK, C. and USBECK, K., Steinbach, Hallenberg, Germany. Dec. 31, 1931, No. 36094. Convention date, March 30. [Class 66.] In a can-opener of the kind comprising a main plate having a cutting blade mounted thereon and a feed wheel to engage the rim of the cam, the cutting blade 1 is mounted on the upper end 2 of the plate, a lever 16 is pivoted to said plate to carry the feed wheel 23, and a relatively wide guide support 18 is mounted on or is integral with the lever and extends wedge-shape towards the feed wheel to hold the plate at the proper angle to the can. The knife 1 is recessed on both sides at 5 so that it may yield resiliently perpendicular to its own plane, a bolt 8 passing through an aperture in the blade or the bending of the material of the upper end 2 of the plate into the recesses 5 preventing deflection of the blade in its own plane. The pinion 20, feed wheel 23, and wing nut for operating the feed wheel are all mounted on a flat-sided axle on the lever 18. In use, the wing handle is rotated to cause engagement of the pinion 20 with the teeth 21 at the top of the aperture 22 in the plate, to move the lever 16 to the left. The opener is then placed on the cam with the feed wheel below the upper rim and the wing handle is turned to move the lever 16 to the right. This pulls the knife blade downwardly and causes it to pierce the end of the cam. Continued rotation of the wing handle causes the end to be cut out. A stop 19 prevents rubbing of the pinion 20 against the end of the aperture 22. - The Specification as open to inspection under Sect. 91 also describes an opener with a feed wheel fixed directly to the main plate and a pivoted knife blade which is swung away to enable the opener to be fitted to the can and then swung down to pierce the end. The knife is resiliently mounted by means of a leaf or spiral spring. The end of the knife remote from the cutting edge is shaped to form a handle for manipulation, or may be formed as a cap lifter for opening bottles. The guide support for ensuring the correct inclination of the opener is integral with the main plate. A cover is provided for the wings of the handle for turning the feed wheel, to prevent slipping of the fingers. This subject-matter does not appear in the Specification as accepted.
