909,839. Batteries; joining metal and ceramic or glass. SVENSKA ACKUMULATOR A.B. JUNGNER. Feb. 27, 1959 [March 8, 1958], No. 6845/59. Classes 36 and 53. A metal accumulator case has a glass or ceramic lid fused to the case and to the polepiece passing through the lid. The lid may be made of metal, as shown at 1 in Fig. 2, in which case the polepiece 2 is fixed to the lid by a glass or ceramic bead 3 fused to both parts. Instead of being fused directly to the lid, the bead may be fused to a washer 5 welded to the lid as shown in Fig. 4. Fig. 5 shows a modification in which a resilient metal member 8 is welded to the polepiece and to a glass or ceramic ring 3. |
