Patent number: 6117528Abstract: The present invention is an improved device for delivering a release agent to fuser rollers employed in various printer devices, such as laser printers, fax machines, copier machines, etc. The release agent delivery device of the present invention comprises an elongated web of microporous membrane (e.g., expanded polytetrafluoroethylene) bonded to a substrate, filled with release agent, and mounted between two shafts. The web spans across the fuser roller so that the roller is simultaneously cleaned and oiled during normal operation. When the portion of the web in contact with the fuser roller becomes contaminated or expends its release agent supply, the web can be advanced to place a fresh surface in contact with the fuser roller.Type: GrantFiled: May 3, 1999Date of Patent: September 12, 2000Assignee: W. L. Gore & Associates, Inc.Inventors: Alex R. Hobson, Robert L. Sassa

Patent number: 6110565Abstract: A heat bond seaming tape has a base formed of a sheet of paper or a paper-like material and an overlying strip of an open mesh material. A plurality of transversely spaced, longitudinally extending beads of a hot melt thermoplastic adhesive material is placed on a top surface of the mesh for adhering the tape to the backs of adjacent carpet edges. A strip of a polyolefin such as a semi-rigid high density polyethylene material is sandwiched between the base sheet and the strip of open mesh material and extends longitudinally along the center of the strip and extends transversely across the carpet seam to prevent seam buckling. The base sheet and reinforcing strip can be extruded as an integral one piece member of the high density polyethylene prior to being joined with the mesh and hot melt adhesive.Type: GrantFiled: April 27, 1998Date of Patent: August 29, 2000Inventor: James A.

Patent number: 6054090Abstract: A process for steam-sterilizing label-bearing containers stacked with the labels in contact, without destroying the labels such as occurs if the labels are printed by thermal transfer for product-variable data. The process features laser-ablating imagewise the label to remove an ink layer so as to expose either a contrasting ink layer below, or a metal foil or polymer substrate. Such containers are then readily stacked on the labels and sterilized without thermal damage to the labels.Type: GrantFiled: July 9, 1998Date of Patent: April 25, 2000Assignee: Johnson & Johnson Vision Products, Inc.Inventors: Donnie Jerome Duis, Daniel Tsu-Fang Wang, James Malcolm Peck
