Publication number: 20040136733Abstract: A printing apparatus places multiple images on a sheet 10, at least once on one side, and at least once on an opposite side. After the first printing, the sheet is inverted by an inverter 50 and sent to a duplex path 42. Sensors 20, 40, both in a feed path 22 and the duplex path 42 detect the side edge of the sheet 10 to register the position of the sheet 10 to a image rendering device 14. A user has the option to input preferences at a user interface 26, the preferences including running average and registration options. More specifically, the user has the option to choose a number of sheets used to calculate a running average for registration of both the simplexed and duplexed sheets. The user also has the option to select between image to image registration, and image to page registration for duplex printing.Type: ApplicationFiled: January 15, 2003Publication date: July 15, 2004Applicant: XEROX CORPORATIONInventors: Deborah M.

Patent number: 6373042Abstract: A printing apparatus places multiple images on a sheet, either by re-feeding the sheet through a duplex path back to a marking device, or by feeding the sheet to successive marking devices. An edge position detector upstream of the marking device determines the location of the sheet so that an image may be precisely placed on the sheet. The system ensures that images on both sides of a sheet are in registration with each other.Type: GrantFiled: August 29, 2000Date of Patent: April 16, 2002Assignee: Xerox CorporationInventors: Deborah M.

Patent number: 6042326Abstract: In a grain cart equipped with a lower horizontally-disposed input drag auger, a vertically disposed lift auger, and an upper horizontally disposed discharge auger, a unique drive train is used. The lift auger and the discharge auger can be activated independently of the input auger in order to empty their contents on start-up of the grain cart discharge system. By so doing the strain on the drive train is considerably lessened thus permitting very large grain carts to be emptied without damage to the drive train system. A hydraulic cylinder activates a belt-tightener between a drive sheave and a driven sheave. The driven sheave is attached to the axis of the drag auger. When the hydraulic cylinder is extended, pressure exerted on the belt causes the input auger to rotate and to feed the lift and discharge augers.Type: GrantFiled: July 16, 1998Date of Patent: March 28, 2000Assignee: Bourgault Industries Ltd.Inventors: Dean Thomas, Darren Borstmayer, Ronald Allan

Patent number: 6018664Abstract: A method of balancing availability of uplink (102) and downlink (101) frequency bandwidths includes determining a demand level for use of downlink (101) frequency bandwidth, and occupying artificially a portion of uplink (102) frequency bandwidth based on the demand level to balance the availability of the uplink (102) and downlink (101) frequency bandwidths. Occupying artificially a portion of uplink (102) frequency bandwidth includes limiting access to a plurality of uplink time slots in uplink (102) communication. Failure to receive a demand for originating a call on uplink (102) communication or a demand by at least one of a plurality of mobile stations to terminate its uplink (102) communication triggers occupying artificially a portion of uplink (102) frequency bandwidth.Type: GrantFiled: April 23, 1998Date of Patent: January 25, 2000Assignee: Motorola, Inc.Inventor: Dean Thomas Skarin

Patent number: 5920746Abstract: An apparatus which transfers a developed image from a photoconductive member to a sheet. A sheet baffle guides an advancing sheet to the photoconductive member at the transfer station. The sheet baffle has an elongated axis extending in a transverse direction to the planer surface of the photoconductive member. A sensing unit, located prior to the transfer station, generates a signal indicative of the sheet basis weight. A regulator, responsive to the signal from the sensing unit, adjusts the position of the sheet baffle to position the elongated axis thereof at a selected angle relative to the planer surface of the photoconductive member. This angle is greater for a lightweight sheet than for a heavyweight sheet.Type: GrantFiled: August 24, 1998Date of Patent: July 6, 1999Assignee: Xerox CorporationInventors: Dean Thomas, Robert A. Gross

Patent number: 5823741Abstract: A seal joint including a sealing member for sealing segmented components of a gas turbine engine is spaced from the gas path to provide more effective cooling. The segments include radial extension flanges spacing the seal joint from the gas path. Various cooling arrangements are adaptable to the modified segments to provide for open or closed circuit impingement or convection cooling plus film cooling. Excessive thermal gradients are avoided as the entire corner of the segment is evenly cooled. Moreover, air usage at the joint is bounded by seal leakage with no extra dedicated cooling air.Type: GrantFiled: September 25, 1996Date of Patent: October 20, 1998Assignee: General Electric Co.Inventors: Daniel Ross Predmore, Iain Robertson Kellock, Victor Hugo Correia, John Howard Starkweather, Dean Thomas Lenahan

Patent number: 5656376Abstract: In a marine vessel having a drive shaft that extend rearwardly from its hull, wherein the drive shaft has a coupling and a bearing assembly along its length that are supported by struts, which struts are also secured to the hull of the vessel. A coupling cover encompasses the coupling and is mounted adjacent to a bearing assembly. A fairwater encompasses the coupling cover and is attached to the bearing assembly or the strut associated therewith to define a chamber and a clearance space between the fairwater and the coupling cover for directing fluids therethrough and through the bearing assembly to lubricate such bearing assembly. Vanes are located on the coupling cover or on a separate support located within such chamber to enhance the fluid flow through the bearing assembly.Type: GrantFiled: June 5, 1995Date of Patent: August 12, 1997Assignee: The B. F. Goodrich CompanyInventors: Gary Michael Rafferty, Dean Thomas Dutton, W. Randall Tucker

Patent number: 5467180Abstract: An apparatus for advancing a sheet from a moving imaging member having an unfused image after transfer of the image to the sheet. After the image is transferred to the sheet, the sheet is advanced by a transport to a fuser. The transport has low impedance, high air flow to draw the sheet toward the transport for acquisition. As the sheet is moved across the transport, an increased air flow impedance causes a low vacuum pressure in the transport to provide a low drive force that minimizes quality and motion disturbances on the sheet. The low drive force exerted on the sleet is lower than a holding force of the sheet to the moving imaging member thus causing the sheet to slide on the transport.Type: GrantFiled: October 20, 1994Date of Patent: November 14, 1995Assignee: Xerox CorporationInventors: Michael Malachowski, Charles W. Spehrley, Jr., Dean Thomas, Michelle Remus, Robert R. Schaffer

Patent number: 5462316Abstract: A quick action coupling is provided of male and female coupling parts in which spherical camming members are loosely retained in a multiplicity of circumferentially disposed openings extended radially through the wall portion of the female coupling member. An axially movable collar surrounding the cylindrical wall portion of the female coupling member has an internally disposed camming surface portion which is configured to cam the spherical members radially inwardly upon movement of the collar in the direction of the open end of the coupling member. The male coupling member is provided with an annular end portion interfacing with a compressible sealing ring in the female coupling portion and further has an upwardly open groove disposed in alignment with the spherical members when the end surface portion is in interfacing relationship with the sealing ring.Type: GrantFiled: May 19, 1994Date of Patent: October 31, 1995Assignee: Campbell Fittings, Inc.Inventors: David G.
