198, Conveyors: Power-Driven,

550.01, for a receptacle-like member (e.g., bin, tank, etc.) having therein or thereon a driven conveyor for the purpose of discharging material contained in the receptacle. [At such time as the overlapping projects involving these two classes (198 and 414) are completed, it will be possible to resolve the conflict which apparently exists between the subject matter of this subclass (304) and that of subclass 550.01 of Class 198].

222, Dispensing, appropriate subclasses, especially

251+, for a dispenser having a discharge assistant.
