1,188,333. Soldering; casting composite electrodes. WESTERN ELECTRIC CO. Inc. 23 May, 1967 [23 May, 1966], No. 23861/67. Headings B3F and B3R. [Also in Division H1] The bevelled hubs 33 of the stacked negative grid electrodes 35 of a lead-acid battery are connected together and to a hollow negative post 13, one end of which seats in the hub of the top negative electrode by casting molten lead or a molten low melting alloy in the hollow 24 of the centre section. Alternatively a sleeve or bar of low-melting solder is inserted in the hollow 24 and either the centre section or the entire assembly is heated. In another embodiment, the hubs 33 of the grids are precoated with low-melting solder and the assembly is heated. The grids may be made of lead or alloys thereof with calcium or antimony. |
