4301-22 CONTINUOUS OUTFLOW, WEIGHT-MEASURING BLENDER Abstract of the Disclosure The continuous outflow, weight-measuring blender contained in a separate and remote facility is connected to a constant output production facility, such as a plant for placing blended product in small marketable containers. The blender includes typical constituent inputs, such as solvent and solvent additive. Each of these constituents is supplied to the system by separate positive displacement pumps and piping leading to a common flex hose output to a weight-measuring tank. The weight-measuring tank is connected by positive mechanical connections, such as rods under tension, to a scale interior of the plant. The scale face has an indicator which undergoes excursion between position sensors, such as electric eyes. When the system is electrically activated, a first position sensor detects zero weight from the measuring tank and remotely calls for the pumping of the first constituent, such as solvent. This pumping continues until the indicator in excursion reaches a second position indicator. Upon sensing the second position indicator, remote pumping of solvent ceases and remote pumping of solvent additive commences and continues until excursion of the indicator reaches a third position indicator sensor. At the third position indicator, remote pumping of additive ceases, the bottom dump valve is activated to a ready state, and the system cycle stops until emptying of the weight-measuring tank occurs. A blend-holding tank provides constant outflow to the production facility. When a probe measures a predetermined remaining level of blend within the blend-holding tank, the bottom dump valve when activated to the ready state remotely empties the weighted measuring tank by gravity flow. Upon excursion of the weight indicator to the zero position, the bottom dump valve closes and is deactivated from the ready state and the cycle repeats. Filling of storage tanks or otherwise supplying additional constituent liquids to the system can occur at any time, without interference with the weight-measuring process. Moreover, should the supply run short, the bottom dump valve will not be activated to the ready state; consequently, a partial blend of constituents, i.e., a blend of the incorrect proportion of constituent liquids, is prevented from exiting the blender. 2.
