Title: Alkaline storage battery with negative iron electrode
IPC: H01M4/38
Filed: 1957-10-21
Abstract: 811,288. Batteries. McGRAW-EDISON CO. Oct. 21, 1957 [Nov. 11, 1956], No. 32759/57. Class 53. The active material of a negative electrode for an alkaline accumulator consists of iron powder with a small amount of ferrous sulphide corresponding to 0.03 to 0.1 per cent of sulphur. The mixture may be first prepared by dissolving iron in sulphuric acid, and separating ferrous sulphate crystals by centrifuging. The crystals are partly dehydrated, and then roasted at 1500‹ F. The ferric oxide so formed containing some iron sulphate is then washed, centrifuged, dried, and treated with hydrogen at 1000-1500‹ F. whereby metallic iron containing some ferrous sulphide is produced. This product is moistened and partly oxidized by heat to form a mixture of iron, iron oxide and about 0.02 per cent of sulphur. The amount of sulphur may be then increased to the required amount of at least 0.03 per cent by several methods. In one method, the time of the roasting operation, the frequency of stirring, or the time of the washing operation is reduced to cause a greater proportion of ferrous sulphate to remain. Alternatively sulphur-containing material may be added to the ferric oxide during the centrifuging operation, as by spraying with a solution of sulphate of iron, ammonium, sodium or potassium. In another method hydrogen sulphide or sodium sulphide is dissolved in the alkaline electrolyte to be introduced into the battery. This method may also be used to activate or regenerate worn-out negative iron electrodes. A further method consists in adding sulphur or sulphide of iron or mercury to the original powdered iron mix to bring the amount of sulphur to the required proportion.

Abstract: 521,048. Furnace linings. ALLMANNA. SVENSKA ELEKTRISKA AKTIEBOLAGET. Nov. 11, 1938, No. 32863. Convention date, Nov. 18, 1937. [Class 51 (ii)] A composite lining for an induction furnace comprising an inner layer of material resistant to high temperatures and to mechanical and chemical action, and an outer heat-insulating layer, is made by first ramming the outer layer around a core and drying it out, and then ramming the inner layer around a smaller core. The material for the outer layer consists of grains of aluminium oxide bound together by aluminium silicate and an organic agglutinant and after the mass has been rammed the core is heated to allow its removal without 'causing the mass to lose its shape, after which the heating is completed at about 1,000‹C. by means of a smaller core which allows moisture to escape uniformly. The inner surface of this layer is then coated with a varnish containing zirconium oxide and chrome ore and the inner layer is rammed round a core preferably turned to a smooth external surface. The materal for this layer consists of zirconium oxide and a basic oxide, e.g., of barium, which are pre-coloured and crushed. An innermost lining of magnesite may be applied when necessary for the metallurgical process to be carried out in the furnace. The heat-insulating layer may be made porous by including in the mass organic substances which are volatilized by heat. Specification 500;057, [Group V], is referred to.

Abstract: 641,551. Automatic control systems for electrolysis cells. FERRAND L. Nov. 6, 1946, Nos. 33047 and 33048. Convention dates, Dec. 29, 1945, and June 3, 1946. Addition to 637,579. [Class 38 (iv)] [Also in Group XXXVI] In apparatus as claimed in the parent Specification means are provided for controlling the temperature of the bath, which means operate in priority to the means for vertically adjusting the anodes in response to variations of the voltage between the terminals of the cell. As shown, the temperature controlling means for operation when the cell is cooled by natural heat dissipation comprises relays P1 and P2 and three temperature-controlled switches, viz. switch n which is closed in the normal temperature range from t<SP>1</SP> to t<SP>11</SP>; switch f which closes to energize P1 on attaining a temperature t 1  lower than t<SP>1</SP> and switch c which closes to energize P2 on attaining a temperature t 2  higher than t<SP>11</SP>. The switch n is included in the energizing circuits of relays mu and du over the contacts U1 and U2 of relay RVP so that for abnormal temperatures when switch n is open, relay RVP cannot control relays mu and du to operate the anode lift- or lower-motors. Operation of switch f closes an energizing circuit for relay P1 which locks itself over contacts W1 and manual switch G, and opens contacts Z1 to ensure that relay RVP cannot control the anode control motors but provides an energizing circuit over contacts 125, 126 for relay mu to initiate operation of the anode control motors to lift the anodes. Similar circuits exist for relay du on closure of switch c to initiate operation of the motors to lower the anodes. Switches f and c also initiate the operation of visual and audible signal devices α and # respectively. In a modification of the temperature control means when the cooling of the bath is effected artificially, the contact n is replaced by a double pole " break " switch operable at the lower temperature limit and by a " make-and-break " combination switch operable at higher temperature limit to operate a relay for controlling the cooling means such as an air blower, a holding circuit for this relay being interrupted by the double pole break switch when the temperature reaches the lower limit.
