Abstract

8446. Eley, C. V. A. Nov. 6. Cells; gas exits. -A glass, porcelain, or other acidproof cell b is provided with a cover d of similar material, adapted to be sealed by means of an abutting r i n g g screwed some distance down into the mouth of the metal case c, of a miners' or like lamp. A gas exit i may be provided i n t h e cover, and when the cell is of glass there may be apertures j in the case for ascertaining the level of the electrolyte. Specification 25,366/08 is referred to.
