Abstract
A differential motion conveyor () for conveying products along an elongated trough structure () supported for reciprocal movement relative to a counterweight base structure () of a weight significantly greater than the weight of the trough structure. A rotational actuator () moving in a singular direction reciprocates the trough structure lengthwise relative and counterweighed base structure at a substantially continually varying velocity of the actuator to achieve a desired differential acceleration rate of the trough structure between the two opposing directions of longitudinal movement of the trough structure.
