Patent number: 8886080Abstract: A device for cleaning a photoconductive member in an image forming device. The device includes a blade extending across the photoconductive member and having an edge that contacts a surface of the photoconductive member to remove toner therefrom. An elongated seal disposed adjacent the blade extends across a length of the blade such that an opening for receiving removed toner is formed between the elongated seal and the blade. The elongated seal includes at least one tab projecting at each longitudinal end thereof and extending between the blade and the photoconductive member so as to prevent a longitudinal end section of the edge of the blade from contacting the surface of the photoconductive member.Type: GrantFiled: April 30, 2012Date of Patent: November 11, 2014Assignee: Lexmark International, Inc.Inventors: Eugene David Allen, Brian Lester Boettcher, Alan Stirling Campbell

Patent number: 6485207Abstract: A printer assembly includes an idler pulley, a printhead carrier belt, an idler-pulley spring, and a ratchet stop. The printhead carrier belt is operatively connected to the idler pulley and extends in an inboard direction from the idler pulley. The idler-pulley spring biases the idler pulley in an outboard direction to maintain belt tension as the belt lengthens during wear. The ratchet stop is located inboard of the idler pulley and operatively engages the idler pulley against movement of the idler pulley in the inboard direction, wherein such inboard movement would cause printing errors.Type: GrantFiled: March 7, 2001Date of Patent: November 26, 2002Inventors: Eugene David Allen, Sung Hwan Song, Ryan Timothy Ward

Patent number: 5829662Abstract: A surgical stapler is provided which is insertable through an endoscopic tube to enable a surgeon to staple a hernia patch to tissue inside a body cavity. The endoscopic surgical stapler includes a staple cartridge pivotally mounted on the distal end of a support tube extending from a handle provided with an actuator mechanism for actuating a staple forming mechanism inside the staple cartridge to fasten staples to the tissue. The staple cartridge is adjustable to different angular orientations relative to the support tube. The staple actuator mechanism is operable to actuate the staple cartridge in any of the angular orientations. The support shaft is rotatable about its longitudinal axis relative to the handle to adjust the rotational orientation of the support shaft and the staple cartridge. The staple cartridge is rotatable about its longitudinal axis relative to the support shaft to adjust the rotational position of the staple cartridge relative to the support shaft.Type: GrantFiled: September 9, 1996Date of Patent: November 3, 1998Assignee: Ethicon, Inc.Inventors: Eugene David Allen, James J.
