Patent number: 7670650Abstract: A method for producing a replaceable fuser member including a thin, seamless or welded high temperature nickel sleeve, a base cushion positioned around the sleeve and an outside topcoat applied over the base cushion elastomer layer. The sleeve is replaceable on a machine mandrel positioned in an electrophotographic copying machine in a fuser section of the electrophotographic copying machine. The method includes the use of a mandrel having a coefficient of thermal expansion similar to that of the sleeve to support the sleeve during positioning of a cured base cushion layer around the sleeve and a cured topcoat layer over the cured base material.Type: GrantFiled: September 15, 2003Date of Patent: March 2, 2010Assignee: Eastman Kodak CompanyInventors: Jiann-Chen Chen, Biao Tan, Allen Kass, Garold F. Fritz, Steven O. Cormier, Ralph E. Williams, Joseph A. Pavlisko

Patent number: 6589048Abstract: A roller for use in a fuser assembly of a reproduction apparatus adapted to operate at an elevated temperature up to in the range of approximately 750° F. The roller includes a generally elongated substantially cylindrical tube. End gudgeons are provided for sealing the ends of the cylindrical tube. Each of the end gudgeons is respectively associated with an end of the cylindrical tube such that after a weld joint is formed between the cylindrical tube and the end gudgeon, the end gudgeon provides a compression joint to prevent the cylindrical tube from separating from the end gudgeon, due to material creep, at elevated operating temperatures.Type: GrantFiled: April 6, 2001Date of Patent: July 8, 2003Assignee: NexPress Solutions LLCInventors: Allen Kass, Terence Michael Miller, Rainer J. Bleil, Jiann-Hsing Chen

Patent number: 4832891Abstract: A method of making a bonded permanent magnet including the steps of dissolving, in a solvent, an uncured epoxy resin having an incorporated catalyst which is inactive at a temperature of about 120.degree. F. Particles of a rapidly quenched rare earth-iron-boron alloy are added to the epoxy resin solution. The solution with the particles are mixed at a temperature of about 120.degree. F. until the solvent is removed and the magnetic particles are substantially uniformly coated with the resin. The epoxy coated particles are then cold-pressed into a compact to form a magnet and the epoxy compact is then cured by heating.Type: GrantFiled: November 25, 1987Date of Patent: May 23, 1989Assignee: Eastman Kodak CompanyInventor: Allen Kass
