Patent number: 9163279Abstract: A device (1) for carrying out a chemical or biochemical reaction and detecting the results is described. The device may be used in an assay to detect a target nucleic acid in a sample. The device includes (i) a well (8) in which a chemical or biochemical reaction such as a nucleic acid amplification reaction may be effected in a liquid phase or a receiver for such a well; (ii) a channel (16) extending from the well; (iii) a lateral flow assay device (32) arranged to receive liquid contents from channel, on a bibulous membrane thereon. The membrane contains elements that are able to detect the products of the chemical or biochemical reaction such as a target nucleic acid. Methods for using such devices and apparatus for carrying out assays using these are also described and claimed.Type: GrantFiled: November 2, 2010Date of Patent: October 20, 2015Assignee: The Secretary of State for Environment, Food & Rural Affairs, acting through the Animal Health and Veterinary Laboratories AgencyInventors: Philip Wakeley, Graham Gutsell

Publication number: 20060024398Abstract: Apparatus is disclosed for repairing a flaw in a surface, particularly in the field of vehicle glass repair. The apparatus has a housing adapted to engage the surface to be repaired, a repair seal for sealing between the housing and around the flaw to be repaired to define a repair space over the flaw. A reservoir communicates with the repair space and, in use, contains liquid repair material. A vacuum pump communicates with the repair space and the reservoir to apply a partial vacuum to the repair space and to the reservoir without repair liquid from the reservoir being drawn into the repair space in order to degas separately the flaw and repair liquid in the reservoir. After appropriate degassing, repair liquid from the reservoir is caused to flow into the repair space to fill the repair space with repair liquid.Type: ApplicationFiled: September 27, 2005Publication date: February 2, 2006Inventors: Philip Rawlins, Douglas MacArthur, Robert Lister, Graham Gutsell

Publication number: 20050172960Abstract: A valve mechanism is provided for use in an inhaler comprising a pressurised container, and a metering chamber, and a valve mechanism wherein the inlet and outlet valves are separate and can be operated independently. The pressure of the fluid in the canister is used to aid the opening of the outer valve so reducing the force to fire a dose. A variant of the valve mechanism allows the user to select from a range of dose volumes bv appropriate orientation of the stem.Type: ApplicationFiled: July 18, 2003Publication date: August 11, 2005Applicant: THE TECHNOLOGY PARTNERSHIP PLCInventors: Graham Gutsell, Nicholas Bowman, Iain McDerment, Patrick Campbell
