1414271 Cells for use in a surrounding pressure medium VARTA BATTERIE AG 18 April 1973 [19 April 1972] 18790/73 Heading H1B A cell 1 intended for use submerged in a liquid medium 20 has its electrolyte space 3 connected by a tube 4 to a pressure-equalizing reservoir 5 having elastic walls. The reservoir 5 is also submerged in the liquid medium and is collapsed by the liquid pressure to force electrolyte 6 into the space 3. Gas liberated in the cell passes through a splash arrester 8 into a dome 7 closed by a valve 10. At a predetermined gas pressure the gas lifts the valve and passes through a space 11 and hole 14 into the surrounding medium 20.
