A warning system for a fluid mixing system provides for automatically mixing precise concentrations of photographic processing chemistry to be used in an X-ray film processor. The system produces a fresh batch of mixed solution whenever a previous batch has been reduced to a predetermined minimum volume. The warning system includes a first sensing means responsive to the presence or absence of a predetermined quantity of a first fluid contained within a fluid supply as well as a second sensing means responsive to the level of fluid in a reservoir. The warning system also includes first and second indicators to indicate an absence of fluid in the fluid supply and a predetermined low level of mixed fluid in the reservoir.

Warning system for fluid mixing and dispensng system

A fluid mixing system and method is disclosed for automatically mixing precise concentrations of photographic processing chemistry to be used in an X-ray film processor. The system produces a fresh batch of mixed solution whenever a previous batch has been reduced to a predetermined minimum volume. A pair of substantially identically constructed mixing units are provided to produce both developer and fixer solutions for film processing. Each unit has: a chemical supply structure for supplying chemicals from containerized supplied; a storage and mixing tank structure which underlies the chemical supply structure and defines a reservoir for mixing the chemistry with water; a water input valve for selectively introducing water under pressure into the tank structure; control apparatus for conditionally controlling operation of the water valve; and a chemical release assembly which is coupled to and actuated by the water valve. The chemical release assembly is operated by the pressure of the water as the water is admitted through the water valve. Operation of the release assembly causes piercing of the containers, allowing the chemistry to drain into the reservoir. The pressurized water creates a swirl for agitating and thoroughly mixing the chemistry and the water.

Fluid mixing and dispensing system

The containerized fluid supply includes one or more bottles housed in a container for supplying prepackaged quantities of constituent chemicals of fixer and developer solutions. Each bottle includes a septum sealed over its mouth, which septum is pierceable to release the bottle contents. In order to prevent improper mixing of chemicals, the various bottles can be fitted within a given container only in one way and a particular container can be used with only a particular mixer.
