  • Patent number: 7954668
    Abstract: A system and method detect when a product container from which a product is dispensed is empty or nearly empty, and provides a notification of the product status. The system includes a load cell that deflects at a first rate of distance per unit load when a load less than a critical load is positioned to be weighed by the load cell, and a load cell bracket positioned such that the free end of the load cell contacts the load cell bracket when a load substantially equal to or greater than the critical load is positioned to be weighed by the load cell. The load cell bracket may prevent the load cell from further deflection, or it may permit deflection of the load cell at a second rate of distance per unit load when the load cell is in contact with the load cell bracket.

  • Patent number: 7942978
    Abstract: A system and method are disclosed for cleaning articles within a chamber of a warewash machine. The warewash machine has a rinse sump for collecting a rinse agent dispensed into the chamber and a wash sump for collecting a wash agent dispensed into the chamber. The method includes a wash phase during which the wash agent is dispensed into the chamber during and an auxiliary rinse phase during which the rinse agent is dispensed into the chamber. The wash machine includes a controllable deflector for directing the wash agent to the wash sump during the wash phase and the rinse agent to the rinse sump during the auxiliary rinse phase. The method also includes a final rinse phase during which water from an external source is dispensed into the chamber. The controllable deflector direct the water dispensed during the final rinse phase to the rinse sump such that the water combines with the rinse agent therein. The rinse agent is re-used during at least one subsequent auxiliary rinse phase.

  • Publication number: 20110083698
    Abstract: A system for regulating a reverse osmosis system to obtain zero wastewater. A reverse osmosis apparatus filters water from the fresh water supply into a concentrate rinse stream and a permeate rinse stream. A concentrate storage tank and a permeate storage tank are downstream of the reverse osmosis apparatus and receive the concentrate rinse stream and the permeate rinse stream, respectively. A concentrate solenoid valve and a permeate solenoid valve control the flow of the concentrate rinse stream and the permeate rinse stream from their respective storage tank. An institutional dishmachine receives the concentrate rinse stream and the permeate rinse stream during a rinse cycle of the institutional dishmachine. A control system is operatively connected to the concentrate solenoid valve and the permeate solenoid valve and control flow of the rinse streams into the institutional dishmachine.

  • Publication number: 20110077772
    Abstract: A chemical product dispenser dispenses a chemical product having at least one active ingredient during a primary dispense cycle based on time or some other factor. After the chemical product has been dispensed, the dispenser determines the amount of chemical product that was dispensed. The dispenser then determines whether the dispensed amount of chemical product is within a defined threshold of a desired amount. If not, the dispenser proceeds to dispense additional chemical product during one or more make-up dispense cycles until the threshold is satisfied.
