Abstract: An auto flow controller which may be used to automatically release a number of component liquids which are to be transmitted to a mixing tank without constantly having to replenish the liquid component chemicals. A sensor located in a mixing tank is equipped with sensors which commands a set of storage containers to release a predetermined quantity of liquid component chemical. This quantity may be controlled by use of level graduated sensors which control pumps or solenoids or by means of a single sensor which initiates timer equipped pumps or solenoids. A combination of these methods may be used. Pump feed, gravity feed or combination of both are utilized.

Abstract: An automatic flow system for an Automixer which provides preset amounts of developer and fixer ingredients to the Automixer on a continuous basis. A plurality of containers are provided with each container having a predetermined volume in accordance with the desired mixing proportions. Control valves respectively control the flow between the containers and the Automixer. A plurality of storage drums are interconnected to the containers by means of additional control valves. The low level signal from the Automixer causes the containers to supply the predetermined volumes to the Automixer. The high level signal from the Automixer causes the storage drums to replenish the supply to the containers.
