Abstract: A method and apparatus are disclosed for sizing preferably small diameter sleeves, wherein the method comprises the steps in any effective order of: (a) providing an electrically conductive sleeve and a die; (b) positioning a portion of the sleeve in the die; (c) positioning a portion of an electrically conductive member inside the sleeve; (d) forming a direct electrical connection between the sleeve and the member; and (e) creating a magnetic field to expand the sleeve.

Abstract: Distortion-free method of mounting an end piece member on a thin-walled hollow tube member, particularly in the assembly of photoreceptor drums and the like, includes the steps of supporting an expandable end piece member within the chamber of an air centering device with its central axis aligned vertically; applying a layer of flowable adhesive to the interior surface of an open end of the hollow tube member; freely suspending the tube member above the end piece member with the open end remaining free of radial distortion and directed toward the end piece member; centering the tube member, by means of the air centering device, to concentrically align the tube member with the end piece member; inserting the end piece member into the tube member; deformingly expanding the end piece member until the layer of flowable adhesive is sufficiently compressed between an outer peripheral edge of the end piece member and the interior surface of the tube member, so as to absorb any dimensional discrepancies therebetween;

Abstract: A device is described comprising an elongated electroforming mandrel, the mandrel comprising at least a first segment having at least one mating end and a second segment having at least one mating end, the mating end of the first segment being adapted to mate with the mating end of the second segment, means to temporarily maintain the mating end of the first segment mated with the mating end of the second segment during an electroforming process, each of the segments having a circumferential, electrically conductive electroforming surface located at at least the mating end.

Abstract: A composite metal article is disclosed comprising at least a first elongated electroformed hollow member and a second electroformed elongated hollow member, each of the hollow members comprising at least a first sleeve and a second sleeve, one sleeve of each of the hollow members having a perimeter larger than the perimeter of the other sleeve of the same member, at least a segment of the outer surface of one sleeve of the second elongated hollow member being adjacent to and substantially surrounded by the inner surface of one sleeve of the first elongated hollow member.
