    Filed: February 22, 1977
    Date of Patent: August 4, 1981
    Inventors: August J. Pacini, James L. Halley
  • Jet action chemical feeding method
    Patent number: 3937399
    Abstract: Apparatus for feeding a quantity of chemical into a stream of liquid by directing a jet of liquid onto a solid soluble body containing the chemical. A chamber receives a solid body of chemical composition which is soluble when exposed to a jet of water or other liquid. The feeding apparatus includes an elongated tube mountable at an inclined angle relative to a horizontal surface, and provided with a liquid inlet at a lowermost lower end to direct a jet of liquid in a longitudinal direction into the tube to impinge against a soluble body of chemical composition received within the tube. A liquid outlet opening is positioned at an uppermost elevation of the inclined tube, so that gas which is evolved from the chemical composition stick and which is not in solution in the liquid can nevertheless flow out of the feeding apparatus through the outlet opening.
    Type: Grant
