Patent number: 9618369Abstract: Various uses of visible light interference patterns are provided. Suitable interference patterns are those formed by diffraction from patterns of apertures. Typical uses disclosed herein relate to spatial metrology, such as a translational and/or angular position determination system. Further uses include the analysis of properties of the light itself (such as the determination of the wavelength of the electromagnetic radiation). Still further uses include the analysis of one or more properties (e.g. refractive index) of the matter through which the light passes. Part of the interference pattern is captured at a pixellated detector, such as a CCD chip, and the captured pattern compared with a calculated pattern. Very precise measurements of the spacing between maxima is possible, thus allowing very precise measurements of position of the detector in the interference pattern.Type: GrantFiled: August 25, 2009Date of Patent: April 11, 2017Assignee: THE UNIVERSITY COURT OF THE UNIVERSITY OF GLASGOWInventors: Jonathan Mark Ralph Weaver, Phillip Stephen Dobson, David Paul Burt, Stephen Thoms, Kevin Edward Docherty, Yuan Zhang

Patent number: 9410570Abstract: A clamp holds two members together. The first member includes a recess into which a fastener is located. A bore is provided to the recess to allow a tool to be used to operate the fastener. The second member is arranged to accept the fastener and so join the members. The recess and bore are sized to prevent release of the fastener through the bore. In this way, the fastener cannot easily be removed or lost when the clamp is in use and is tamperproof. The clamp is used to hold portions of a sleeve around a body of the tool, and to hold scraper blades and/or brushes to the body.Type: GrantFiled: March 4, 2013Date of Patent: August 9, 2016Assignee: Specialised Petroleum Services Group LimitedInventors: James Edward Atkins, George Telfer, Edward Docherty Scott

Patent number: 7794658Abstract: System, circuits, and methods to reduce or eliminate uncompensated voltage drop between an electrode of an electrochemical cell usable for analyte measurement. In one example, a system is provided that includes a test strip, a reference voltage circuit, an operational amplifier connected to the reference voltage circuit to provide a pre-determined fraction of a reference voltage substantially equal to the test voltage applied to the first line, the operational amplifier having an output configured for one of a connected or disconnected state to the first line, and a processing circuit connected to the output of the operational amplifier and the first line such that, during a disconnected state between the output and the first line, the processing circuit remains in connection with the first line.Type: GrantFiled: July 25, 2007Date of Patent: September 14, 2010Assignee: LifeScan, Inc.Inventors: Mahyar Z.

Patent number: 7681650Abstract: A ball valve seat (10) is disclosed which provides a temporary seal for a plug (40). The valve seat comprises a substantially cylindrical body (30) of a first volume, which defines a seating surface (34). A pressure differential is developed across the valve seat when the plug sealingly engages the seating surface. The body is formed of an elastic material which compresses from a first volume to a smaller second volume by application of a force on the plug, to provide a clearance which is greater than a plugging dimension of the plug, thus allowing passage of the plug downstream. After passage of the plug, the body returns to the first volume.Type: GrantFiled: April 29, 2005Date of Patent: March 23, 2010Assignee: Specialised Petroleum Services Group LimitedInventors: George Telfer, Edward Docherty Scott

Patent number: 7416029Abstract: A downhole tool which can perform a task in a well bore, such as circulating fluid radially from the tool. The function is selectively performed by virtue of a sleeve moving within a central bore of the tool. Movement of the sleeve is effected by dropping a ball through a ball seat on the sleeve. Movement of the sleeve is controlled by an index sleeve such that the tool can be cycled back to the first operating position by dropping identical balls through the sleeve. Embodiments are described wherein the balls are deformable, the seat is deformable and the seat provides a helical channel through which the ball passes.Type: GrantFiled: March 31, 2004Date of Patent: August 26, 2008Assignee: Specialised Petroleum Services Group LimitedInventors: George Telfer, Edward Docherty Scott, Rae Andrew Youngor, James Edward Atkins

Publication number: 20080145139Abstract: A clamp (10) for holding two members (12, 14) together. The first member includes a recess (30) into which a fastener (38) is located. A further access port (42) is provided to the recess to allow a tool (44) to be used to operate the fastener. The second member is arranged to accept the fastener and so join the members. The recess and port are sized to prevent release of the fastener through the port. In this way, the fastener cannot easily be removed or lost when the clamp is in use and is tamperproof. Embodiments of a downhole tool are described where the clamp is used to hold portions of a sleeve around a body of the tool, and to hold scraper blades (384) and/or brushes (394) to the body.Type: ApplicationFiled: August 23, 2005Publication date: June 19, 2008Applicant: Specialised Petroleum Services Group LimitedInventors: James Atkins, George Telfer, Edward Docherty Scott

Patent number: 7204326Abstract: A turbine is disclosed which includes a turbine blade housing having an inner facing portion of a first material having a first coefficient of expansion, and a turbine blade body having an outer facing portion of a second coefficient of expansion greater than said first coefficient. In a preferred embodiment, the blade housing comprises a number of steel shroud rings and the turbine blade body comprises a number of stators and rotors of a thermoplastic material. An interference fit between stator blades and the shroud rings is enhanced in use due to the difference in thermal and/or hydrophilic coefficients of expansion of the first and second materials.Type: GrantFiled: August 13, 2003Date of Patent: April 17, 2007Assignee: Smith International, Inc.Inventors: Andrew McPherson Downie, Guido Ernesto Pezzani, Edward Docherty Scott
