1,167,464. Sealed electric cells. SOC. LES PILES WONDER. 7 Feb., 1968 [17 Feb., 1967; 2 Feb., 1968], No. 6089/68. Heading H1B. A sealed electric cell, Fig. 2, encased between two half-shells, 4 and 5, crimped together, which form the cell terminals, is characterized by a removable insulating cover, 8, which temporarily protects one of the half-shell terminals, the edge, 8, of the cover extending into the crimping where it forms a seal between the two halves and the other half-shell is crimped inwards over it. The cover may be of polythene and have a central hole 8 3 . It may be removed by cutting ties 8 4 . The cell may comprise a depolarizer mass, 1, of MnO 2 , and a zinc anode 2, separated by electrolyte 3. The lower halfshell, 5, may be of nickel plate iron or stainless steel and the shells may be separated by insulator 6. Fig. 3 shows a cylindrical cell embodying the invention. |
