  • Electrolytic chlorine generator with cover element
    Patent number: 4900418
    Abstract: Electrolytic chlorine gas generating apparatus including a housing, a volume of water inside the housing, a hollow salt cell disposed in the water in the housing, a volume of salt particles and of water in the salt cell, an anode mounted in the housing contacting salt solution in the salt cell, a cathode mounted in the housing, means for causing current to flow between the anode and cathode to generate chlorine gas at the anode, and a line attached to the housing to carry away chlorine gas produced by the anode. The apparatus, when the water level in the salt cell becomes low and the top of the salt solidifies into a "dome", prevents chlorine gas from accumulating beneath the solidified salt dome and exploding.
    Type: Grant
    Filed: December 27, 1988
    Date of Patent: February 13, 1990
    Inventor: Robert E. Maddock
  • Electrolytic chlorine generator with salt spacer
    Patent number: 4793909
    Abstract: Electrolytic chlorine gas generating apparatus including a sousing, a volume of water inside the housing, a hollow salt cell disposed in the water in the housing, a volume of salt particles and of water in the salt cell, and anode mounted in the housing contacting salt solution in the salt cell, a cathode mounted in the housing, means for causing current to flow between the anode and cathode to generate chlorine gas at the anode, and a line attached to the housing to carry away chlorine gas produced by the anode. The apparatus, when the water level in the salt cell becomes low and the top of the salt solidifies into a "dome", prevents chlorine gas from accumulating beneath the solidified salt dome and exploding.

  • Apparatus for generating chlorine gas
    Patent number: 4744877
    Abstract: Electrolytic chlorine gas generating apparatus including a housing, a volume of water inside the housing, a hollow salt cell disposed in the water in the housing, a volume of sat particles and of water in the salt cell, an anode mounted in the housing contacting salt solution in the salt cell, a cathode mounted in the housing, means for causing current to flow between the anode and cathode to generate chlorine gas at the anode, and a line attached to the housing to carry away chlorine gas produced by the anode. The apparatus, when the water level in the salt cell becomes low and the top of the salt solidifies into a "dome", prevents chlorine gas from accumulating beneath the solidified salt dome and exploding.
