20090283656Post mounting assembly and method for molten metal pump - A molten metal pump apparatus that includes a base member, at least two (2) support members or posts, and post sockets. The lower end of the posts are mounted to the base and forms a cement-less pump joint which is an objective of the present invention. The upper end of the post is connected to the post socket to form a cement-less pump joint which is a further object of the present invention. The connection joint between the posts and the base member and the post socket does not require cement to form or secure the joint. Therefore a replacement post identical to posts of the present invention may be provided without the need to dig out a cement joint but instead can be more easily removed and replaced.11-19-2009

20100157004Multi-Color Ink Tank With Features Spaced by Distances Ensuring Interface with Printhead and Carrier Support Structure - A multi-color ink tank includes certain features that properly interface with features on a printhead and carrier support structure to operatively seat the ink tank in the carrier support structure in a sealed flow communicative relationship with the printhead. These interface features are spaced apart relative to one another at distances (or dimensions) that ensure the desired seating and sealing of the ink tank in the carrier support structure and thereby the reliable supply of ink for operation of the inkjet printing system.06-24-2010
20100165060Individual Ink Tank with Features Spaced by Distances Ensuring Interface with Printhead and Carrier Support Structure - A individual ink tank includes certain features that properly interface with features on a printhead and carrier support structure to operatively seat the ink tank in the carrier support structure in a sealed flow communicative relationship with the printhead. These interface features are spaced apart relative to one another at distances (or dimensions) that ensure the desired seating and sealing of the ink tank in the carrier support structure and thereby the reliable supply of ink for operation of the inkjet printing system.07-01-2010
20100165061Mono Ink Tank with Features Spaced by Distances Ensuring Interface with Printhead and Carrier Support Structure - A mono ink tank includes certain features that properly interface with features on a printhead and carrier support structure to operatively seat the ink tank in the carrier support structure in a sealed flow communicative relationship with the printhead. These interface features are spaced apart relative to one another at distances (or dimensions) that ensure the desired seating and sealing of the ink tank in the carrier support structure and thereby the reliable supply of ink for operation of the inkjet printing system.07-01-2010
20110032312MULTI-COLOR INK TANK WITH FEATURES SPACED BY DISTANCES ENSURING INTERFACE WITH PRINTHEAD - A multi-color ink tank includes certain features that properly interface with features on a printhead to operatively seat the ink tank in the printhead in a sealed flow communicative relationship with the printhead. These interface features are spaced apart relative to one another at distances (or dimensions) that ensure the desired seating and sealing of the ink tank in the printhead and thereby the reliable supply of ink for operation of the inkjet printing system.02-10-2011
20110032313INDIVIDUAL INK TANK WITH FEATURES SPACED BY DISTANCES ENSURING INTERFACE WITH PRINTHEAD - A individual ink tank includes certain features that properly interface with features on a printhead to operatively seat the ink tank in the printhead in a sealed flow communicative relationship with the printhead. These interface features are spaced apart relative to one another at distances (or dimensions) that ensure the desired seating and sealing of the ink tank in the printhead and thereby the reliable supply of ink for operation of the inkjet printing system.02-10-2011
20110032316MONO INK TANK WITH FEATURES SPACED BY DISTANCES ENSURING INTERFACE WITH PRINTHEAD - A mono ink tank includes certain features that properly interface with features on a printhead to operatively seat the ink tank in the printhead in a sealed flow communicative relationship with the printhead.

20090169239Cleaner Blade Lubrication for a Printer Belt Component - The present disclosure relates to a method and apparatus for removing contaminants from a belt in a printer. A blade is provided that contacts with the belt surface to form a nip where the belt is configured to either receive an image for transfer to a sheet of media or transport media within the printer for receipt of toner images. The blade surface is coated with a fluoropolymer resin in combination with a polymeric binder. The coated blade/belt provides a reduced coefficient of friction at the nip to reduce belt stall and/or belt flipping, which may lock the blade to the belt and prevent further printer operation. The coated blade/belt herein is particularly useful when applied to printing operations that utilize chemically processed toner.07-02-2009
20090169273Doctor Blade Surface Energy Modification - The present disclosure relates to a surface energy reduction material in the form of a topcoat or additive to a coating that may be applied to a toner regulating member such as a doctor blade which may reduce toner build-up about a nip region, pre-nip region, and/or post-nip region. The surface energy reduction material may be include any material having a surface energy of less than or equal to 35 dynes/cm, for example, between 15-30 dynes/cm, including all values and ranges therein. The surface energy reducing materials may include any material that provides a 25% or more reduction of the surface energy of the doctor blade compared to an untreated doctor blade, for example, greater than or equal to 50% reduction or greater than or equal to 75% reduction, including all values and ranges therein.07-02-2009
