Patent ID: 7267473

Claim:
An apparatus for transferring fluidic compositions for coloring concrete comprising: a tank including an interior defined by walls; a fluid transferring apparatus in communication with the tank for withdrawing a concrete coloring fluid from the interior of the tank; the fluid transferring apparatus comprising a pump and a discharge line extending from the pump for transferring the concrete coloring fluid from the tank to a supply of concrete; a cover, removably attachable with respect to the tank, the cover moveable between a first position, where the interior of the tank is closed to the ambient environment and a second position, where the interior of the tank is open to the ambient environment to receive the concrete coloring fluid; a system for rinsing the tank with an aqueous fluid, including, an aqueous fluid intake port connected to a source of the aqueous fluid; and, a dispenser in communication with the aqueous fluid intake port and configured for providing the aqueous fluid to the interior of the tank for contacting the walls of the interior of the tank, the dispenser coupled to the cover; and, a controller for operating the fluid transferring apparatus and the system for rinsing the tank, the controller in electrical communication with the aqueous fluid intake port and the pump, and the controller comprising a preload mode for directing the aqueous fluid intake port to direct the aqueous fluid to enter the interior of the tank, a pump mode for directing the pump to transfer the concrete coloring fluid from the tank through the discharge line, and a rinse mode for directing the aqueous fluid intake port to direct the aqueous fluid to enter the interior of the tank.
