Multiplexed system for dispensing multiple chemicals to multiple destinations
First Claim
1. A method for dispensing liquids in a system having a first transport means including a pump, a reservoir of chemicals, a collapsible input tube one end of which is in fluid communication with said reservoir, with said remaining end having an aperture in fluid communication with said pump, a chemical flow tube coupled to a water flow tube, with said water flow tube being in fluid communication with a supply of water, said method comprising the steps of:
- selectively placing said reservoir in fluid communication with said pump;
transporting a chemical flow from said input tube through said chemical transport means under force of said pump;
transporting a flow of water from said supply of water through said water flow tube;
combining said chemical flow and said flow of water to form a diluted chemical solution; and
transporting said diluted chemical solution through a solution flow tube to a system output tube.

Abstract
The present invention relates to dispensing chemicals from a multiplexed group of chemicals and delivering the chemicals to a multiplexed set of industrial washers. An input multiplexer operatively couples a selected system input tube to a chemical pump, thereby permitting a selected liquid chemical to be pumped from a chemical container through the chemical delivery system to a selected washer.

14. A liquid chemical dispensing system for use with a plurality of liquid chemical containers, said system comprising:
-
a first fluid transport means; a plurality of system input tubes; an input multiplexer coupling said plurality of system input tubes to said first transport means, said input multiplexer operatively coupling a selected system input tube to said first transport means, said input multiplexer including a plurality of first multiplexer tubes, at least a portion of each of said first multiplexer tubes capable of being pinched in order to restrict a flow of a chemical in said tube, a plurality of pinchers, each of said pinchers coupled to a corresponding first multiplexer tube, and pinchers pinching said corresponding first multiplexer tube if said corresponding first multiplexer tube is not selected; and
a flow enabler coupled to a pincher corresponding to a selected first multiplexer tube, with each of said pinchers including a spring mechanism, said spring mechanism for establishing a force on said corresponding first multiplexer tube thereby pinching said first multiplexer tube;a water supply; and a second fluid transport means coupled to said water supply and to said first fluid transport means, wherein an output of said second fluid transport means comprises a solution of said selected liquid chemical and said water. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38)

39. A liquid dispensing system having a reservoir of chemicals and a supply of water, said system comprising:
-
a first fluid transport means adapted to create a flow of said chemicals; a system input tube; an input valve in fluid communication with both said first fluid transport means and said system input tube, with a portion of said input tube adapted to be collapsible and said input valve having a valve element including a pincher positioned proximate to said collapsible end portion, said pincher being resiliently biased to apply a spring force against said collapsible end to selectively pinch-off fluid flow therethrough, with a flow enabler operably coupled to said pincher to selectively reduce said spring force and allow fluid flow through said collapsible end; and a mixing apparatus coupled to both said water supply and said first fluid transport means, said mixing apparatus being adapted to create a flow of said water and mix said flow of water with said flow of chemicals, defining a dilute chemical flow. - View Dependent Claims (40, 41, 42, 43, 44, 45, 46, 47, 48)
