Number: 198/526
Name: Conveyors: power-driven > Conveyor system having a gravity conveyor section > With means to affect flow > Moving flow control means coordinated with power-driven conveyor section
Description: Apparatus wherein the flow-affecting means comprises an element (or series of elements) which moves (e.g., orbitally, rotatably, etc.) through or within the path of flow from a gravity section to a power-driven section in timed relation with the movement of the power-driven section for the purpose of momentarily interfering with flow along that path at such times no one of the successive conveying elements (e.g., a bucket) of the power-driven section is properly positioned to receive the flow.
