Abstract

978,426. Batteries. BURNDEPT Ltd. April 12, 1961 [Jan. 19, 1960], No. 1980/60. Heading H1B. A dry cell is sealed by an inflatable membrane 8 shown in the position it assumes when extrusion of the electrolyte takes place. Initially, the membrane lines the cavity above the dolly 3. A vent 7 allows this movement to take place. Specification 620,445 is referred to.
