Patent number: 9409419Abstract: A printer includes a vacuum belt assembly for moving print media in a media feed direction along a media path. The vacuum belt assembly includes: a plurality of endless belts tensioned between first and second pulleys, the first and second pulleys having respective first and second axes of rotation perpendicular with the media feed direction; and a vacuum chamber for drawing print media onto an upper surface of the belts. Each belt is independently laterally slidable along one of the first and second axes.Type: GrantFiled: June 20, 2013Date of Patent: August 9, 2016Assignee: Memjet Technology LimitedInventors: Bill Stone Cressman, Kenneth Andrew Regas, Jonathan Day Lucas, David Collins Burney, Patrick Kirk, Steve Inderieden, Neil Doherty, Lai Say Poh, Joo Beng Koh, Gilbert Magsakay

Publication number: 20150029281Abstract: A printer includes a vacuum belt assembly for moving print media in a media feed direction along a media path. The vacuum belt assembly includes: a plurality of spaced apart endless belts tensioned between first and second pulleys; a vacuum chamber for drawing print media onto an upper surface of the belts; and a plurality of vacuum antechambers communicating with the vacuum chamber, each vacuum antechamber having a perimeter opening for suction engagement with print media, a length dimension of each perimeter opening extending longitudinally in the media feed direction. A first perimeter opening of a first vacuum antechamber positioned towards an upstream side of the vacuum belt assembly is shorter than a second perimeter opening of a second vacuum antechamber positioned towards a downstream side of the vacuum belt assembly. The upstream and downstream sides are defined with respect to the media feed direction.Type: ApplicationFiled: October 15, 2014Publication date: January 29, 2015Inventors: William Stone Cressman, Kenneth Andrew Regas, Jonathan Day Lucas, David Collins Burney, Patrick Kirk, Steve Inderieden, Neil Doherty, Lai Say Poh, Joo Beng Koh, Gilbert Magsakay

Patent number: 8939574Abstract: A printer includes a vacuum belt assembly for moving print media in a media feed direction along a media path. The vacuum belt assembly includes a plurality of moving belt modules, each moving belt module including: a body having an internal chamber defining at least part of a vacuum chamber; a first pulley positioned at a first end of the body; a second pulley positioned at a second end of the body; and a set of spaced apart endless belts tensioned between the first and second pulleys. The belts are non-apertured and the vacuum chamber communicates with an interstitial gap defined between each adjacent pair of belts in the set so as to draw print media onto an upper surface of the moving belt module.Type: GrantFiled: June 20, 2013Date of Patent: January 27, 2015Assignee: Memjet Technology Ltd.Inventors: William Stone Cressman, Kenneth Andrew Regas, Jonathan Day Lucas, David Collins Burney, Patrick Kirk, Steve Inderieden, Neil Doherty, Lai Say Poh, Joo Beng Koh, Gilbert Magsakay

Patent number: 8333105Abstract: Apparatus, systems and methods are described for preconcentrators, chemical sensing systems and gas chromatographs. A preconcentrator is described that comprises a hollow enclosure containing a sorbent material. The enclosure may be a capillary tube that can be formed in to a desired shape and that may be heated. Heating may be accomplished by passing an electrical current through the capillary or other hollow enclosure form. The sorbent material can be a liquid, a solid, a porous ceramic material and/or a chemiselective polymer. The sorbent material can be coated to the inner wall of the enclosure. The hollow enclosure may be maintained in an insulated chamber. The preconcentrator acts to concentrate a vapor passed through the preconcentrator to a chemical sensing array that can detect chemicals present in the vapor. A gas passed through the hollow enclosure can provide a chemically concentrated input to a chromatographic column.Type: GrantFiled: April 30, 2010Date of Patent: December 18, 2012Assignee: Seacoast Science, Inc.Inventors: Jonathan Day Lucas, Manna Leon Warburton, Todd Mlsna, Sanjay V. Patel, Stephen Terrence Hobson

Publication number: 20040154383Abstract: This invention relates to a device and a method by which to directly measure based on pressure and/or temperature data and to control the flow rate, viscosity, density, velocity, pressure or temperature of a variety of fluids in motion with improved reliability and less susceptibility to disturbance of the measuring and control system while, at the same time, offering maximum flexibility for influencing measurement and control data. Components of the flow meter system are described and the methods for calibrating the system and determining pour volumes are explained.Type: ApplicationFiled: December 11, 2003Publication date: August 12, 2004Inventors: Darin Kent Woolf, Jonathan Day Lucas
