Abstract: A pair of door stabilizer bracket units, each unit including a clamping mechanism for gripping a vertical frame member of a separate one of a pair of double swinging doors that are closed when the vertical frame members are adjacent one another, the doors being hinged along a respective vertical line remote from a respective one of said vertical frame members, the bracket units when the doors are closed having parts that interengage and limit relative vertical movement of said doors at said vertical frame members while not substantially impeding opening and closing movement of the doors or requiring manipulation of a unit on the respective door to release the bracket units from any interengagement such that the bracket units can be simply disengaged from any interengagement by door opening movement.

Abstract: A shaker table for settling randomly oriented items in a generally rectangular container with sidewalls prone to bulge at lower portions thereof, including a pan with a generally horizontal bottom for supporting the container and an underlying pallet while being shaken, a power drive for shaking the pan, container, and pallet, and side restraints limiting lateral movement of the container during shaking movement.
