1. A tank system for multicolor dispensing of tinting fluids to printing equipment or the like, requiring a continuous flow of fluids, comprising:
- a. a plurality of tank means for containing fluids, at least one per color to be dispensed, each having inlet ports for entry of fluids into the tank located above the level of the fluid in the tank, and outlet ports for exit of fluid from the tank means;
b. inlet manifold means for conveying fluid to the tank means, for location above the fluid level in the tank means, comprising;
1. a level conduit having top, bottom, and side walls, a plurality of outlet ports in the side walls, a plurality of input port means for admitting fluid into the level conduit;
2. a plurality of valve means, at least one per tank, each having an input and an output, the input sealably connected to an outlet port of the conduit, and the output of at least one valve means per tank connected to an inlet port of one of the tank means and each having open and closed positions for controlling fluid flow from the outlet ports;
3. each of the outlet ports and valves being level with the conduit, such that fluid cannot pool in the ports, valves or conduit;
c. output manifold means for conveying fluid from the tank means, located above the tank means, comprising;
1. a sloping conduit having a top, a bottom, and side walls, upper and lower ends, a plurality of inlet ports in the top and a plurality of output ports;
2. Drain valve means for draining the output manifold, having open and closed positions, an input sealably connected to the lower end of the conduit and an output connected to an input port in the conduit of the inlet manifold means;
3. A plurality of inlet valve means, at least one for each tank means, located at the inlet ports of the conduit, each having an input and an output, the output sealably connected to an inlet port of the conduit;
4. a plurality of input tube means each having two ends, an output end connected to the input of the inlet valve means, and an input end for location below the fluid level in the tank means;
d. a plurality of pump means connected to the output manifold means for causing fluid to flow into the output manifold means from the tank means via the tube means;
e. output means for supplying fluid to the printing equipment having an input connected through a valve to an output port of the output manifold means, and an output adapted to supply fluid to the printing equipment;
f. input means for accepting excess fluid from the printing equipment having an output connected to an input port means of the inlet manifold and an input adapted to receive fluid from the printing equipment.

Abstract
A multifluid dispensing system especially suited for web tinting machines or the like. A plurality of fluid and, optionally, air-tight tanks are provided. In a recirculating embodiment, the tanks feed fluid to, and receive fluid from, two manifolds. The upper (output) manifold receiving fluid from each tank slopes to gravity drain into the second manifold. The second (inlet) manifold is level to eliminate low spots for fluid accumulation. The inlet manifold drains into the tanks through valves in the side of, and level with, the manifold. A non-recirculating embodiment uses only the second manifold with pressurized tanks. An optional flush tank may be provided.
