Technical Examples

A method of providing a continuous, sequential, and cyclic, if desired, liquid feed to a processor from a plurality of containers, which comprises feeding the liquid from a first of the containers through a first conduit to a reservoir having a float valve, to keep the level of the liquid in the reservoir high enough to maintain the float valve in an upper floating position that closes the float valve. The first conduit is uncontrolled by the float valve. The float valve controls a second conduit which connects with a second container. As liquid is withdrawn from the reservoir for processing, liquid from the first conduit and container replenishes the reservoir until it is exhausted. Then, the liquid level drops, and the float valve opens the second conduit for replenishing the reservoir with liquid from the second container. A crossover valve may be used so that the float valve controls flow from either container connected to the second conduit.
