Abstract: A handle conversion device for facilitating movement of a wheeled object which includes a preexisting handle with a grip member having a longitudinal axis positioned in a plane substantially perpendicular to a desired direction of movement. The handle conversion device includes a hand grip, a neck and an attachment portion. The hand grip includes a longitudinal axis orientated substantially perpendicular to the plane occupied by the grip member of the preexisting handle, and substantially within the plane defined by the forward and rearward movement of the wheeled object. The attachment portion includes a hook member and a retention member which, in combination, act to releasably retain the grip member of the preexisting handle, to controllably maintain the substantially perpendicular relationship of the hand grip for the handle conversion device to the preexisting handle.

Abstract: A method of cleaning a spent anode assembly after removal from an aluminum reduction cell, the assembly including a support rod and yoke and the remaining portions of at least one rigid carbon electrode held on the support rod and yoke and upon which is deposited solidified electrolytic material including fused cryolite, alumina and other materials used in the aluminum reduction process, the method comprising the steps of: (a) coupling a vibratable assembly coupled rigidly to the support rod and yoke; and (b) applying acceleration forces substantially though the centre of gravity of the vibratable assembly and supported spent anode assembly so that each carbon electrode has applied thereto an acceleration pattern to remove the solidified electrolytic material therefrom by generating tensile and shear forces greater than the adhesive force between the electrode and the electrolytic material.
