Latest Patents
Johnson holds a patent for a "Method and apparatus for controlling the concentration of a chemical." This invention includes a method and apparatus for controlling the concentration of wash water in a ware washing machine. A preferred ware washing machine includes a reservoir for holding wash water, a normally closed valve for directing clean water to a dry detergent supply, an electrodeless conductivity cell for monitoring the conductivity of the ware washing solution, and a controller for activating the normally closed valve in response to the difference between the measured concentration and the actual concentration. The concentration controller features an adjustable amplifier that provides an amplified concentration signal equal to a reference signal when the solution's concentration meets the desired level. Additionally, the conductivity cell includes a thermistor that adjusts the voltage of the signal produced by the secondary coil to account for temperature-related concentration changes.
