  • Patent number: 8763856
    Abstract: A method for distributing powdered and liquid chemicals. The method includes introducing water into an upper end of a measuring chamber, injecting liquid chemical through an inlet located at a lower end of the measuring chamber into a chemical chamber that is fluidly coupled to a lower end of the measuring chamber until a desired volume of the liquid chemical has been introduced, pumping the desired volume of liquid chemical and at least some of the water to a washer, inserting water and a desired dose of a powdered chemical into the upper end of the measuring chamber, and transporting the powdered chemical and at least some of the water to the washer.

  • Patent number: 8240514
    Abstract: The chemical distribution system (100) includes at least a first chamber that is fluidly coupled to a second chamber below it, which is in turn fluidly coupled to a manifold below it. In use, water and a powdered chemical are introduced into the first chamber. Liquid chemicals, however, are injected into the second chamber through multiple chemicals inlets in the second chamber. A pressure sensor fluidly coupled to the first chamber is used to accurately measure dosages of the liquid chemical. Once the accurate dosages have been determined, the powdered and/or liquid chemicals are distributed through one of multiple manifold outlets and along a single line (116(a), 116(b)) to one of multiple washing machines (102(a), 102(b)).
