A methodology and apparatus comprises integral material reservoir cylinders which contain separate material bags in which reside a component required for a formulation, or alternate material reservoir containers, typically drums, with a component required for a formulation in each drum, or a combination of both, that provides a volume of material through a supply tube into a valve that directs the material to either: 1) a dispense tube and through a dispense valve, into a receiving container that sits upon a scale, or 2) into a dispense cylinder in which resides a piston that, through the use of a piston drive plate actuator and the piston drive plate actuators' piston drive plate, directs the material through a valve and through a dispenser tube and through a dispense valve and into a receiving container that sits upon a scale.
摘要:
An apparatus for dispensing a plurality of fluids having a turntable, and a plurality of pumps, each connected to a container. The pumps and containers are mounted on the turntable arranged along the circumference of the turntable or part of the circumference of the turntable. At least one of the containers has a larger volume than the other containers or is in fluid connection with a further container positioned towards or at the center of the turntable.

In accordance with an embodiment of the present invention there is provided a dispenser apparatus for dispensing fluids. The dispenser apparatus includes a rotatable table, a plurality of dispensing units. Each dispensing unit has a receptacle for holding a fluid, and each receptacle includes a corresponding pump for dispensing fluid held therein. The dispensing units have a base portion to detachably attach the units to the rotatable table. The dispenser apparatus further includes a stationary dispensing station that has a pump actuator for dispensing fluid held in the receptacle. The apparatus further includes a mechanism for engaging the base portion of a dispensing unit. The mechanism when activated, moves the dispensing units thus rotating the table to align a pump corresponding to a receptacle to the stationary dispensing station, wherein fluid held in the receptacle may be dispensed.

摘要:
This invention relates to an apparatus and a process for rapidly and accurately dispensing fluids, in which at least one component is dispensed into the reaction vessel in two or three stages. In this process, the amount of fluid dispensed in the second and third stages is determined on the basis of the mass flow rate calculated in the preceding sub-step.
