Patent number: 8030368Abstract: Photoinitiated reactions especially in photopolymer technology, as well as photoinitiated color forming reactions are achievable by applying a reactive substrate selected from a polymerisable and/or crosslinkable composition and a color changing substance to a support, activating a latent photoinitiator applied with the reactive substance and subsequently exposing the reactive substrate with the resulting photoinitiator therein to photoreaction conditions wherein actinic radiation causes the substrate to undergo polymerization and/or crosslinking or color change respectively, the substrate being locally modified in its constitution as a result of its exposure to actinic radiation at least one stage of the method, so that the resulting polymerised and/or crosslinked composition or color changed substance corresponds in its distribution on the support to the locations of the modification of the substrate.Type: GrantFiled: December 22, 2006Date of Patent: October 4, 2011Assignee: Lintfield LimitedInventor: Grant Bradley

Patent number: 7530278Abstract: A flow blender device that includes a plurality of input flow conduits and a single output flow conduit. A variable sized orifice is positioned along at least one of the conduits for metering and controlling fluid flowing through the flow blender device. The variable sized orifice can be positioned along any of the input or output flow conduits. The flow blender device can use differential pressure measurements across the variable sized orifices to determine fluid flow rates in the flow blender device.Type: GrantFiled: November 2, 2006Date of Patent: May 12, 2009Assignee: RivaTek, Inc.Inventors: Mark Daniel Litecky, Grant Bradley Edwards, Dennis John Smith, John Allan Kielb

Patent number: 7302863Abstract: A method of improving the accuracy of a variable orifice flow meter that includes characterizing the flow coefficient of the flow meter orifice for different orifice openings and for different differential pressures. The method may be particularly useful with a flow metering and controlling device that includes a fluid flow conduit having at least one planar inner wall and an element having a linear edge configured to mate with the at least one planar inner wall of the fluid flow conduit. The element is movable relative to the conduit to define a flow orifice and vary a cross-sectional area of the orifice. The device also includes a processor configured to calculate the fluid flow based on the cross-sectional area of the orifice, the differential pressure, and the flow coefficient.Type: GrantFiled: August 28, 2006Date of Patent: December 4, 2007Assignee: Rivatek IncorporatedInventors: John Allan Kielb, Grant Bradley Edwards, Dennis John Smith
