Patent number: 5871832Abstract: A guide for leveling the flow of a coating from a nozzle onto a generally cylindrical substrate of a polymeric printing component in a printing machine is provided. The substrate is rotated about its longitudinal axis by a turning apparatus having a axially movable slide for mounting the nozzle to the slide. The coating is spirally applied to the substrate. The guide includes a member operably associated with the slide and moves with the slide. The member has a surface parallel to and slightly spaced from the periphery of the substrate so as to assist in evenly distributing the coating on the periphery of the substrate.Type: GrantFiled: June 26, 1996Date of Patent: February 16, 1999Assignee: Xerox CorporationInventors: Patrick J.

Patent number: 5540844Abstract: Apparatus and method is described for dewatering sludge obtained from a flotation tank, which efficiently handles the sludge and avoids the need for adding polymers to reflock the sludge. The sludge dewatering portion includes a conveyor (40, FIG. 1) which has an uppath portion (42) that receives sludge that is dropped over a cliff (32), the conveyor having a downpath portion (44) which firmly compresses the sludge as it continues to move along the conveyor. The conveyor preferably extends at an incline to the horizontal with the downpath portion lying higher than the uppath portion, and with a fluid conduit lying under the conveyor and carrying liquid downwardly along the incline to a pump (74) that pumps the liquid along a return conduit (80) back to the flotation tank. One conveyor includes an elongated shaft (50, FIG.Type: GrantFiled: July 21, 1995Date of Patent: July 30, 1996Inventors: Donald M. Meylor, Patrick J. Finn

Patent number: 5332641Abstract: A fuser member for fusing thermoplastic resin toner images to a substrate has an aluminum base member and an elastomer fusing surface of a poly(vinylidenefluoride-hexafluoropropylene-tetrafluoroethylene) where the vinylidenefluoride is present in an amount less than 40 mole percent, the elastomer having been cured from a solvent solution thereof with a nucleophilic curing agent soluble in the solution and in the presence of 5 or less than 4 parts by weight of inorganic base per 100 parts of polymer, the inorganic base being effective to at least partially dehydrofluorinate the vinylidenefluoride, and an adhesive layer between the surface of said aluminum base member and the elastomer fusing surface, the adhesive layer having been cured from a solvent solution of a poly(vinylidenefluoride-hexafluoropropylene-tetrafluoroethylene) where the vinylidenefluoride is present in an amount less than 40 mole percent and from about 6 to 20 parts by weight per 100 parts by weight of said poly(vinylidenefluoride hexafluoroType: GrantFiled: April 27, 1992Date of Patent: July 26, 1994Assignee: Xerox CorporationInventors: Patrick J.

Patent number: 5305888Abstract: A floatation separation method is described for separating pieces of fruit or vegetable of the same type, but wherein desirable pieces have a slightly different specific gravity from the undesirable ones, and all have a specific gravity about the same as that of water. The pieces (12, FIG. 3 ) are placed near the surface of a body of water, and a cloud (40) of tiny air bubbles is maintained in the water. As the bubbles float to the surface they encounter the articles and slightly increase their buoyancy. The increase in buoyancy is slight and uniform, so those articles having a density slightly greater than that of the water will remain at the water surface, while those of a slightly greater density cannot be floated by the air bubbles and will sink to the bottom. The cloud of air bubbles is created by allowing air at about atmospheric pressure, to emerge from apertures in a rapidly spinning rotor that open in a direction primarily opposite to the spin direction.Type: GrantFiled: July 27, 1992Date of Patent: April 26, 1994Inventors: Donald M. Meylor, Patrick J. Finn

Patent number: 5242600Abstract: A wastewater flotation separation system is provided, which operates effectively with a minimum of maintenance. The apparatus includes a container (12) for holding wastewater, an inlet (14) located at a lower portion of the container, and an aerator (24) adjacent to the inlet for generating air bubbles that cling to waste particles to bring them to the water surface. A skimming apparatus (30) which skims particles off the surface of the wastewater into a sludge receiver (44) includes a beach device (42) with an inclined upper surface (40), and a belt device (34) that moves a series of scrapers (32) along the surface of the water and along the beach device into the sludge discharge. Each scraper includes a flap of resilient material which is bent as it scrapes along the inclined beach surface.Type: GrantFiled: December 19, 1991Date of Patent: September 7, 1993Inventors: Donald M. Meylor, Patrick J. Finn

Patent number: 5219612Abstract: A method of using multilayered member for fusing thermoplastic resin toner images to a substrate in a fuser system of the type wherein a polymeric release agent having functional groups is applied to the surface of the fuser member.
