Abstract: A diverter swing arm for diverting an article from a conveying surface comprises a central body having a unitary construction and including a pusher portion that has an external face for engaging and diverting a particular article from the conveying surface, and a linkage arm that facilitates connection to an actuator, and a pivot pin received in an opening defined by the central body, said pivot pin defining a pivot axis for rotation of the diverter swing arm relative to the conveying surface. There is no molded-in metal skeleton or frame in the diverter swing arm.

Abstract: An improved pneumatic control for a zero pressure accumulating conveyor includes, in a discharge zone control, a first control valve and a master control valve cooperating to produce an accumulating function for one position of the master control valve, and a continuous discharge zone operation for a second position of the master control valve while all loaded upstream zones operate sequentially upon clearing of their respective adjacent downstream zones. Accumulated items in the discharge zone and in the next upstream zone are sequentially, and not simultaneously, conveyed upon movement of the master control valve to its second position.

Abstract: A chain driven, live roller accumulating conveyor is defined by a plurality of accumulation zones, each having a pneumatically actuated clutch for selectively driving each zone, and a pneumatically controlled brake for braking an idler roller in each zone when the clutch is disengaged. Methods for accumulating are included.
