Patent number: 6187019Abstract: In accordance with the present invention, there is provided a surgical device for attaching a first hollow organ to a second hollow organ and creating a passageway therebetween. The device includes a first member comprising a first prong for entering a wall of the first hollow organ and a second prong for entering a wall of the second hollow organ. The prongs each have a proximal end which attaches to the first member and a distal end extending therefrom. The device further includes a second member having a plow for incising at least one of the hollow organs so as to create a passageway between the hollow organs. The second member further includes a plurality of needle paths on either side of the plow for guiding a needle through the walls of the hollow organ on either side of the passageway. The device further includes a means for driving a needle, having a suture attached thereto, so as to attach the hollow organs together.Type: GrantFiled: October 5, 1999Date of Patent: February 13, 2001Assignee: Ethicon Endo-Surgery, Inc.Inventors: David Stefanchik, David L.

Patent number: 5136333Abstract: An electrophotographic printer (11) having a base (13) and a top (12), the top (12) being pivotable about an axis (23) between a closed position and an open position. The printer (11) receives a supply cartridge (14) on a shelf (22) which is pivotable about the same axis (23) as the top (12) of the printer (11). A counterbalance spring (34) helps to support the shelf (22) and the cartridge (14) below the top (12) of the printer (11) and above the printer base (13) when the top (12) of the printer (11) is in its open position. When the top (12) of the printer (11) is closed, the cartridge (14) is urged into a position adjacent the printer base (13) and locked into an operative position.Type: GrantFiled: June 30, 1989Date of Patent: August 4, 1992Assignee: Lexmark International, Inc.Inventors: James A. Craft, William L. Dollenmayer, James P. Harden, Frank M. Hughes, James J. Molloy

Patent number: 5012289Abstract: A developer apparatus (29) for use in an electrostatic reproduction apparatus includes a large reservoir of toner (34, 44). The toner is located in a supply chamber (39) and is metered to a developer roller chamber (35) from which it is carried by a developer roller (31) past a doctor blade (36) to a photoconductor drum (19) for image development. A toner metering roller (41) rotates with the developer roller (31) to provide a continuous supply of toner from the supply chamber (39) to the developer chamber (35). Once an equilibrium level (65) is reached, the toner metering roller (41) acts to remove toner (34) from the developer chamber (35) to the supply chamber (39) to insure proper operation of the developer roller (31).Type: GrantFiled: August 11, 1989Date of Patent: April 30, 1991Assignee: International Business Machines CorporationInventors: Charles S. Aldrich, Steven L. Applegate, James A. Craft, James J. Molloy, Michael L. Pawley

Patent number: 4943815Abstract: When cover (8) of the laser printer (3) is closed, absence of the replaceable cartridge (15) or the shroud assembly (9) will activate both an electrical and a mechanical interlock. A moveable switch actuator (16) on the shroud assembly will be absent if the assembly is omitted and will not find a guide ramp (46) if the cartridge is absent, thereby assuring power to the light source remains off. A shutter (13) also blocks the normal light path and is moved aside by a pin (14) on the cartridge, and therefore blocks light unless a cartridge is installed. Walls (31) on the cartridge surround the shutter during normal use to form a protective light baffle. The laser printhead (2) is fixed within the shroud so that separation requires a necessary electrical cable (72, 74) to be disconnected.Type: GrantFiled: June 29, 1989Date of Patent: July 24, 1990Assignee: International Business Machines CorporationInventors: Charles S. Aldrich, James A. Craft, James P. Harden, Steven R. Komplin, William S. Rousey, Praful M. Shah, Earl D. Ward II, Bernard L. Wilzbach, Terry L. King

Patent number: 4772143Abstract: A symmetrical printer ribbon cartridge which is refillable. An internal, continuous drive belt (15) provides tension to push studs (33, 35) of the supply spool (23) and of a take-up spool (29) to the ends of notches (31, 32) in cartridge wall 1. When the original supply spool is emptied, a new spool need only be moved into place and the free end of the ribbon pulled from the new spool, directed through the ribbon path in the cartridge, and attached to the remaining spool.Type: GrantFiled: October 29, 1987Date of Patent: September 20, 1988Assignee: International Business Machines CorporationInventors: James A. Craft, James J. Molloy

Patent number: 4661004Abstract: Member (9) has a tension arm (13) over which ribbon (3) feeds. Biasing arm (17) presses member (9) toward brake surface (7), with slot (21) moved until it encounters stud (23). At low tension of ribbon (3), brake surfaces (11) and (7) press and hold ribbon (3). As feed tension increases tension arm (13) forces member (9) back until stud (23) encounters the opposite end of slot (21), after which slightly higher force further opens the brake and arm (13) continues to provide feed tension. The mechanism is small, efficient, smooth functioning, and suited to incorporation as part of a ribbon cartridge.Type: GrantFiled: April 30, 1985Date of Patent: April 28, 1987Assignee: International Business Machines CorporationInventors: Steven L. Applegate, James A. Craft
