Definitions

  • the bottom of the cell has a rubber lining 37 aflixed thereto and this rubber lining has several layers of brick overlying it.
  • the rubber lining protects the steel surface of the bottom of the cell 38 from corrosive attack during electrolysis.
  • the rubber lining 35 protects the side members 39 from corrosive attack during electrolysis.
  • the bricks are placed against the rubber lining to prevent serious corrosive attack of the rubber lining during electrolysis by providing a rather tight interface between the rubber and the surface of the brick. In actual operation when fluid leaks through the brick and begins attacking the rubber surface the tight physical connection between the brick and the rubber lining prevents an accumulative deterioration of the rubber lining and ultimately protects the steel from corrosion.
  • the cell is so constructed that the top member 1 slopes from the gas collection zone to the brine inlet opening 18.
  • the particular pitch of the slope is not of particular consequence, though preferably an incline providing a drop in a vertical direction of about inch per running foot or more is preferred.
  • the sloping top permits the collection of gas bubbles on the undersurface of the cover member 1 at the rubber lining 1'2 and. assists in transporting these gas bubbles as they collect at this surface to the gas collection zone of reduced cross sectional area 20;
