1. An apparatus useful for providing a chemical composition useful to treat an item comprising:
- reservoir means for containing a concentrated form of said chemical composition, said reservoir means having an outlet means through which said concentrated form of said chemical composition exits said reservoir means;
means of providing diluent to said concentrated form of said chemical composition exiting from said reservoir means to form said chemical composition;
electronic control means including a keyboard and a display module associated with said reservoir means and said means for providing diluent and structured to be preset by control information imputed through said keyboard to automatically and independently of the diluent flow control the time during which said concentrated form of said chemical composition exits said reservoir means and to automatically and independently control the flow of diluent from said means for providing diluent, said display module being capable of providing a visual display of said control information imputed through said keyboard; and
nozzle means acting to contact said chemical composition and diluent with said item to be treated.

Abstract
An apparatus useful for providing a plurality of chemical compositions useful to clean an item, e.g., a tank, comprises a plurality of reservoirs each containing a concentrated form of a different chemical composition and each having an outlet through which the concentrate exits the reservoir; a subsystem for providing diluent to the concentrates which exit the reservoir to form the chemical compositions; and a control subsystem to automatically control the time during which each concentrate exits from each reservoir. A method for providing chemical compositions useful to clean an item is also disclosed.

6. An apparatus useful for providing a plurality of different chemical composition useful to treat an item comprising:
-
a plurality of reservoir means each of which being capable of containing a concentrated form of a different one of said chemical compositions, each of said reservoir means having an outlet means acting to provide an exit from the associated reservoir means for the concentrated form of the chemical composition contained in said associated reservoir means; means for providing diluent to said concentrated forms of said chemical compositions exiting from said plurality of reservoir means to form said chemical compositions; electronic control means including a keyboard and a display module associated with each of said plurality of reservoir means and said means for providing diluent and structured to be preset by control information imputed through said keyboard to automatically and independently of the diluent flow control the time during which said concentrated form of chemical composition exits from each individual reservoir means and to automatically and independently control the flow of diluent from said means for providing diluent, said display module being capable of providing a visual display of said control information imputed through said keyboard and; nozzle means acting to contact said chemical compositions and diluent with said item to be treated. - View Dependent Claims (7, 8, 9, 10, 11, 12)
