Patent number: 7730904Abstract: An apparatus (10) for performing microfluidic processes comprising a base (50), a plurality of fluidic modules (20) releasably attached to the base (50), each fluidic module (20) comprising a fluid port (25) and a microfluidic manifold module (40) comprising a plurality of ports (45). A frame (70) is attached to the base (50) for releasably retaining the microfluidic manifold module (40), the frame (70) being moveable relatively to the base (50) to move the microfluidic manifold module (40) into contact with the fluidic modules (20) such that each fluid port (25) of the fluidic modules (20) aligns and seals with a respective port (45) on the microfluidic manifold module (40) thus completing a microfluidic circuit. A method for constructing and testing the apparatus (10) is also disclosed.Type: GrantFiled: December 15, 2005Date of Patent: June 8, 2010Assignee: Syrris LimitedInventors: Mark Peter Timothy Gilligan, Philip James Homewood, Robert J. Ranford, Paul M. Crisp

Publication number: 20030175168Abstract: A method of optimising a reaction in a microreactor. Two reaction fluids A, B as supplied to a microchannel 6 and their relative proportions are varied in a controlled manner. A sensor 13 monitors a reaction characteristic and determines the relative proportion of the fluids which optimises the yield of the reaction product. The total flow rate can also be varied at the optimum relative proportion in order to determine the maximum overall flow rate at which completion of the reactions still occurs.Type: ApplicationFiled: February 14, 2003Publication date: September 18, 2003Inventors: Mark Peter Timothy Gilligan, Philip James Homewood, Rowland Whiffin

Patent number: 6435786Abstract: A cargo barrier net for an aircraft includes a central ring. A plurality of radially projecting webs include a radially inner end that is connected to the central ring. A radially outer end is connected to the airframe. The first circumferential web is connected to a first set of mid-portions of the radially projecting webs. A first set of mid-portions is located radially outside of the central ring. A second circumferential web is located radially outside of the first circumferential web. The second circumferential web is connected to a second set of mid-portions of the radially projecting webs. The second set of mid-portions is located radially outside of the first set of mid-portions. A third circumferential web is located radially outside of the second circumferential web. The third circumferential web is connected to a third set of mid-portions of the radially projecting webs. The third set of mid-portions is located radially outside of the second set of mid-portions.Type: GrantFiled: July 24, 2000Date of Patent: August 20, 2002Assignee: The Boeing CompanyInventors: David A. Breckel, Timothy R. Schwartz, Bernhard Dopker, John W. Startup, James Homewood
