799,469. Batteries. UNION CARBIDE CORPORATION, [formerly UNION CARBIDE & CARBON CORPORATION]. Nov. 22, 1956 [Nov. 23, 1955], No. 35687/56. Class 53. In a primary cell, the peripheral edges of the consumable metal anode 10, separator 12 and depolarizer mix 14 are enveloped by a resilient integrement 18 of insulating plastic material, the whole being contained in a metal cup 24 which is folded inwardly to maintain the elements under pressure. The peripheral edges of the depolarizer and the surface adjacent the separator are covered by a paper blanket 16 and a cathode collector 16, e.g. of carbonloaded plastic material, is interposed between the integrement 18 and the metal cup 24 and is secured by adhesive or heat sealing to the former at 22. The side of the separator 12 which contacts the anode is coated with bibulous material, e.g. methyl cellulose, and the anode may be sealed to the integrement 18 as at 19. A washer 26, interposed between the anode and the metal cup, may also be sealed to the integrement at 25. The metal cup may be of brass coated inside and out with gold. The cells may be stacked to form a battery. |
