Continuous outflow, weight-measuring blender

Apparatus for providing a continuous supply of a weight measured blend of at least two constituent liquids to a main production facility building, said apparatus comprising:

• a free standing tower having at least an uppermost level and a level immediately below said uppermost level;
• a weight-measuring tank contained within said uppermost level having at least one input and at least one output;
• weighing means including a scale having an indicator undergoing excursion disposed interior said main production facility building and a weighing platform disposed in said uppermost level, said weight-measuring tank supported on said weighing platform, said weighing platform operatively connected to said scale so that said indicator undergoes excursion upon said weight measuring tank receiving increasing contents;
• a blend-holding reservoir disposed in said level immediately below said uppermost level in substantial vertical alignment with said weight-measuring tank for receiving gravitationally flowing output of said weight-measuring tank;
• a dump valve and included conduit between said blend-holding reservoir and weight-measuring tank for releasing said liquid constituents to flow by gravity from said weight-measuring tank whereby blended liquid constituents enter said blend-holding reservoir;
• means for opening said dump valve upon said reservoir having blend content below a predetermined amount;
• at least first, second, and third position indicators on the face of said scale for generating respective sequential first, second, and third output signals responsive to the excursion fo said indicator on said scale from said first position to said third position;
• a first constituent liquid input system having a first pump for inputting a first constituent liquid to said weight-measuring tank;
• a second constituent liquid input system having a second pump for inputting a second constituent liquid to said weight-measuring tank;
• means for causing said first signal to actuate said first constituent liquid input system to input said first constituent liquid to said weight-measuring tank;
• means for causing said second signal to actuate cessation of inputting of said first constituent liquid and commencement of inputting of said second constituent liquid;
• first means for causing said third signal to actuate cessation of inputting from said second constituent liquid input system;
• second means for causing said third signal to actuate a pumps not ready circuit to prevent actuation of the pumps upon the reverse excursion of said indicator from and between the third position to the first position:
• and means connected to said first and third indicators for deactivating said dump valve during inputting from said respective first and second constituent liquid input systems, whereby partially blended constituents cannot be released to said reservoir, at least one of said position indicators on said scale being removeably attachable to said scale to generate a signal at different positions of excursion of said indicator on said scale whereby the blending of constituents in said free standing tower is remotely controlled from said scale interior of said main production facility building.
