Abstract
562,280. Batteries. SIEMENS BROS. & CO., Ltd., and LAMBERT, G. M. Dec. 28, 1942, No. 18405. [Class 53] [Also in Group V] In a primary cell having a solid depolarizing mass, the most active depolarizing agent (e.g. manganese dioxide) is in greater concentration at the surface nearest the positive electrode (e.g. zinc) than at the surface nearest the negative electrode (e.g. carbon). The depolarizing mass may be formed in separate cylindrical layers 4, 5, 6 with a different content of manganese dioxide. The three cylindrical layers may be formed by a continuous operation in a machine having a horizontal service table 7 and a carrier table 15, both rotated step by step. The table 7 has three circular rows of holes 8, 9, 10, the diameters of which correspond to the outer diameters of the cylinders 6, 5, 4 respectively, and the table 15 has one row of holes, the arrangement being such that each hole in disc 15 comes successively under a hole in each of the rows 8, 9, 10 in table 7. In position A of table 7, the holes in table 7 are filled from hoppers with depolarizer of different composition, Fig. 3 (not shown) ; in position 11, the depolarizer in one of the largest holes 8 is forced into a hole 16 in table 15 by a pressure spindle 25, Fig. 4, the centre of the mass being forced through a die 27 by a coring spindle 24, so as to leave a cylindrical mass of depolarized in the hole 16. When this hole 16 in plate 15 moves into the positions 12 and 13, the process is repeated, middle and inner cylinders of degolarizer being formed within the outer one, Figs. 5, 6 (not shown). When the hole 16 reaches positions 35, 36, 37 a carbon electrode is forced into the centre of the inner cylinder, Fig. 7 (not shown), the three cylinders are compressed into one mass and the carbon electrode forced home, Fig. 8 (not shown), and the finished dolly is ejected, Fig. 9 (not shown). The invention may also be applied to the layer type of cell. The Provisional Specification states that different depolarizers may be used in the several layers.
