Abstract: An on-board auxiliary split tank system for supplying makeup water and chemical additives to a transit concrete mixing vehicle is disclosed which includes a generally cylindrical water tank designed for generally horizontal deployment having a shaped recess therein and an additive tank configured to nest in said recess of said water tank and which, when nested in said recess, generally completes said cylindrical shape. The water tank and additive tank are formed from a non-metallic material comprising a polymeric component.

Abstract: A control mechanism for controlling the flow of a particulate material through a conduit and comprises a bladder mounted within the conduit that is inflatable between a first, deflated state and a second, inflated state. In its first, deflated state the bladder allows the particulate material to flow freely through the conduit, and in its second, inflated state the conduit is substantially blocked by the inflated bladder and no particulate material may pass. An alternate embodiment of an exteriorly mounted control mechanism comprises a stopper that is moved between a first, open position away from an open end of the conduit and a second, closed position in which the stopper is in sealing contact with end of the conduit.
