  • Apparatus for controlling water level
    Patent number: 4612949
    Abstract: Apparatus for monitoring and controlling the level of fluid in a reservoir. The apparatus utilizes a fluid sensing probe to monitor the level of fluid in a reservoir and can generally be installed in an existing fluid reservoir without requiring structural modification of the reservoir. The apparatus, in determining the level of fluid in a reservoir, compensates for swells and other surface undulations which mask the true fluid level in the reservoir.

  • Electrochemical ionization system for purifying water
    Patent number: 4525272
    Abstract: An improved water purification system. The system utilizes an electrolytic cell and maintains a generally constant current flow through the electrolytic cell when the electrical resistance of water being treated by the cell varies. The relationship between current flow through the electrolytic cell and the temperature of water moving through the cell can generally be represented in linear graphical form.
