Patent number: 11780647Abstract: A food bag closure assembly includes a clip that has a pair of jaws being biased against each other for closing an opened food bag. A gas unit is provided that stores an inert gas and the gas unit is integrated into the clip. The gas unit is in fluid communication with an interior of the food bag when the clip is positioned on the food bag. Moreover, the gas unit is actuated to release a pre-determined volume of the inert gas each time the clip is closed. In this way the gas unit injects the inert gas into the food bag for extending the shelf life of food contained in the food bag.Type: GrantFiled: October 16, 2020Date of Patent: October 10, 2023Inventor: Robert Cairns

Publication number: 20070212360Abstract: The HIF-1 transcription factor drives gene expression changes in hypoxia. While HIF-1 stimulates glycolysis, it also actively represses mitochondrial function and oxygen consumption by inducing pyruvate dehydrogenase kinase 1 (PDK1). PDK1 phosphorylates and inhibits pyruvate dehydrogenase from converting pyruvate to acetyl-CoA to fuel the mitochondrial TCA cycle. This causes a drop in mitochondrial oxygen utilization and results in a relative increase in intracellular oxygen tension.Type: ApplicationFiled: January 17, 2007Publication date: September 13, 2007Inventors: Nicholas Denko, Robert Cairns, Ioanna Papandreou

Patent number: 7208222Abstract: A porous structure having a plurality of bonded sheets each sheet having at least one aperture that partially overlaps an aperture of at least one other sheet. A method of producing a porous structure including stacking a plurality of sheets each sheet having a multiplicity of apertures, and bonding each sheet to its adjoining sheet. An open-pore network structure having a multiplicity of sheets each having a repeatable pattern. At least a portion of each sheet is bonded to the web of an adjacent sheet. The porous area of at least one of the sheets is askew to the porous area of at least another of the sheets. An open-pore structure having a multiplicity of bonded sheets, each sheet having a repeatable pattern defining a multiplicity of perforations, and a plurality of apertures defined by the repeatable pattern, the apertures extending through the perforations of at least two adjacent plates.Type: GrantFiled: July 23, 2004Date of Patent: April 24, 2007Assignee: Viasys Healthcare Inc.Inventors: Jonathan L. Rolfe, Mark P. Amrich, Joseph A. Buturlia, Robert Cairns, Robert Lynch, Michael Gerry

Publication number: 20060051489Abstract: A process for preparation of nutritionally upgraded oilseed meals which are protein and lipid-rich and have a reduced fibre content, and plant oils from oilseeds for use in fish or other non-human animal diets or human foods comprising the steps of: providing a source of oilseed; subjecting the oilseed to heat treatment to substantially reduce the concentration of at least some antinutritional components normally present in the oilseed to obtain heat-treated seed; dehulling the heat-treated seed to produce a meat fraction, a hull fraction or a mixture thereof; and cold pressing the meat fraction or the mixture to yeild the plant oils and the protein and lipid-rich meals.Type: ApplicationFiled: August 18, 2005Publication date: March 9, 2006Inventors: David Higgs, Robert Cairns, Ian Shand
