  • Patent number: 6376088
    Abstract: A method of electroforming a non-ferromagnetic substrate for use in an electrostatographic imaging member includes electroforming a non-ferromagnetic substrate of nickel and one of phosphorus, tin and copper. The substrate can be cylindrical shaped and have a substantially constant inner diameter and outer diameter along a length of the substrate. The substrates can be used in various electrostatographic imaging members including electrographic and electrophotographic imaging members. The methods of this invention can provide seamless imaging members such as photoreceptors that can be used in apparatus that include magnetic developer systems, without adversely interacting with magnetic brushes and magnetic toners.

  • Patent number: 6051148
    Abstract: A photoreceptor fabrication method involving a photoreceptor substrate having a metal surface, comprising etching the metal surface of the photoreceptor substrate with an etching solution and forming a metal oxide layer on the metal surface with the etching solution, wherein the etching of the metal surface and the forming of the metal oxide layer are conducted in the absence of an electric current.

  • Patent number: 5997722
    Abstract: A method for producing a photoreceptor having a substrate subjected to a surface finishing treatment to result in a finished substrate surface, wherein the method includes:(a) analyzing the finished substrate surface by performing a first surface energy reading, a first ellipsometry reading, a first x-ray diffraction reading, and a first profilometry reading;(b) removing electrochemically via an alternating voltage or alternating current a portion of the finished substrate surface, thereby resulting in a cleaned substrate surface;(c) analyzing the cleaned substrate surface by performing a second surface energy reading, a second ellipsometry reading, a second x-ray diffraction reading, and a second profilometry reading, wherein the removing step (b) is accomplished to the extent that the second surface energy reading and the second ellipsometry reading are measurably changed from the first surface energy reading and the first ellipsometry reading, but the second x-ray diffraction reading and the second profilo

  • Patent number: 5803417
    Abstract: An apparatus for supporting a sink having a laterally extending peripheral flange. The apparatus includes an elongated horizonal support bar and a pair of sink support members supported on a support bar in spaced relation to each other. Each of the sink support members includes an engagement portion for engaging the support bar and a bifurcated arm portion extending from the engagement portion for receiving the peripheral flange of the sink therebetween. The engagement portion of each of the sink support members is selectively movable to a plurality of lateral locations along the support bar to adjust the spacing between the pair of sink support members.

  • Patent number: 5716183
    Abstract: A hand truck for moving objects from one location to another is disclosed as including a frame extending longitudinally from a foot end to a handle end, the frame including a first elongated member, a second elongated member spaced from the first elongated member, and a cross member extending between and fixed to the first and second elongated members. The hand truck also includes at least one ground engaging wheel rotatably mounted to the frame for rotation about a wheel axis adjacent the foot end thereof. A first arm slidingly connected to the first elongated member, wherein the first arm extends substantially perpendicular to the first elongated member, and a second arm slidingly connected to the second elongated member, wherein the second arm extends substantially perpendicular to the second elongated member are provided, as is a brace member slidingly connected to the frame.

  • Patent number: H1247
    Abstract: A developer composition with a conductivity of from about 10.sup.-6 to about 10.sup.-12 (ohm-cm).sup.-1 over a toner concentration of from about 1 to about 6 weight percent, which developer is comprised of a toner containing resin particles, pigment particles and a metal salt of a fatty acid; and carrier particles with rough surfaces thereon.
