Patent application numberDescriptionPublished
20090127645In-line light sensor - The sensor includes an optical waveguide defined in a light-transmitting medium. The waveguide includes a sensing portion and an non-sensing portion. The light-transmitting medium included in the sensing portion has defects that provide the light-transmitting medium with a deep band gap level between a valence band of the light-transmitting medium and a conduction band of the light-transmitting medium. The deep band gap level is configured such that the waveguide guiding light signals through the light-transmitting medium in the sensing portion causes free carriers to be generated in the light-transmitting medium. A detector is configured to detect the free carriers in the sensing region of the waveguide.05-21-2009

20090242490Method and Apparatus for Fluid Separation - A method is disclosed for separating a multiphase fluid stream comprising a heavier fluid component and a lighter fluid component, the method comprising causing the fluid to flow along a first helical flowpath, the first helical flowpath having a first pitch, the first helical flowpath being sufficiently long to establish a stabilised rotating fluid flow pattern for the stream causing the uniform rotating fluid to flow along a second helical flowpath, the second helical flowpath having a second pitch, wherein the second pitch is greater than the first pitch; and removing the lighter fluid from a radially inner region of the second helical flowpath. An apparatus for carrying out the method is also disclosed. The method and apparatus are particular suitable for the separation of oil droplets from water, especially from water for reinjection into a subterranean formation as part of an oil and gas production operation. The method and apparatus are conveniently applied on a modular basis.10-01-2009
20100011557Flow Block - A method of manufacturing a flow block for use as a T-Block, tree block, manifold block or valve block, the method including: machining a main bore in a body; forming an opening in the body in a side wall of the main bore; providing an insert including a first bore intersecting with a second bore and being in fluid communication with each other; forming a substantially curved surface on at least part of the intersection between the first bore and the second bore; and inserting the insert into the opening, such that the first bore is substantially aligned with the main bore in order to provide a fluid flow path between the main bore and the second bore.01-21-2010
20100064893Separator and Method of Separation - A method of separating a multiphase fluid, the fluid including a relatively high density component and a relatively low density component, that includes introducing the fluid into a separation region; imparting a rotational movement into the multiphase fluid; forming an outer annular region of rotating fluid of predetermined thickness within the separation region; and forming and maintaining a core of fluid in an inner region. Fluid entering the separation vessel is directed into the outer annular region and the thickness of the outer annular region is such that the high density component is concentrated and substantially contained within this region, the low density component being concentrated in the rotating core. A separation system employing the method is also provided. The method and system are particularly suitable for the separation of solid debris from the fluids produced by a subterranean oil or gas well at wellhead flow pressure.03-18-2010
20100288389Choke Assembly - A choke assembly. In some embodiments, the choke assembly includes a choke element having a fluid flow passage therethrough. The choke element includes a cage having a plurality of apertures therethrough for the passage of fluid and a plug moveable with respect to the cage. The plug has an end surface that defines a boundary of the fluid flow passage through the choke and is moveable to open or close each of the apertures through the cage, whereby the flow of fluid through the cage is controlled. The apertures in the cage are disposed in a first portion and a second portion separated by a land. Each of the first and second portions has a least one aperture therein. The plug may be positioned with its end surface disposed to intersect the land, such that each aperture is fully open or fully closed to the flow of fluid.11-18-2010

20100300700Wellhead Assembly - An assembly for use on a wellhead includes a tree body including an internal main bore arranged in use to be aligned with the bore of a wellhead housing; the tree body including a lateral bore extending through the tree body from the internal bore; the tree body further including means for connecting to a connector so as to align the internal bore of the tree body with an internal bore in the connector, in use the tree body and the connector together forming a horizontal tree. The tree body may include one or more integrally formed bores and valves to provide fluid flowpaths for the annulus and/or cross-over functions. A wellhead assembly including the tree assembly is also provided.12-02-2010

20120184198Ventilation Arrangements - A ventilation arrangement for ventilating the interior of a building. The arrangement includes a duct extending to above the roof of the building. The duct is square in cross section and is divided into four quadrants by internal vertical divider plates. A louvre arrangement is provided on each side of the upper part of the duct to receive air into the building on a windward side of the duct, and to expel air from a leeward side of the duct. A closure arrangement is provided for selectively partially or wholly closing the louvre arrangements, for instance in the event of bad weather.07-19-2012

20100224700Spray gun - An air spray gun for paint has a tubular body, having an integral screw thread receiving a threaded collar. This secures an air cap against the end of the tube. The air cap has four horns, formed with obliquely inwards directed bores, for patterning the spray, by impinging on it from opposite sides in a manner analogous to that for known air caps having two horns.09-09-2010
20130026249Spray Gun - An air spray gun for paint has a tubular body, having an integral screw thread receiving a threaded collar. This secures an air cap against the end of the tube. The air cap has four horns, formed with obliquely inwards directed bores, for patterning the spray, by impinging on it from opposite sides in a manner analogous to that for known air caps having two horns. Behind the air cap in the tube is an air distributor for distributing air to either or both of the pairs of air horns as required to patterning of the paint spray. Paint flow is controlled by a needle withdrawable from a paint nozzle for paint flow. The to needle is in two parts, a front interchangeable part and a rear part connected to the trigger.01-31-2013

20120318890Spray Gun - An air spray gun operated by blowing air past a nozzle, the air drawing the spray liquid from the nozzle and imparting momentum to it. The air cap includes formations to bias air flow towards the air horns having patterning air directed to them. The central opening extends towards the air horns, either in the form of a square opening with the corners of the square closest to the horns, or in the form of a compound curved shaped providing pronounced curvature of the corners at the axes toward the horns. This significantly improves paint spray patterning and discourages paint deposition on the air horns.12-20-2012
