Patent number: 9126207Abstract: A separator for separating a multiphase mixture comprising a pressure vessel supported for rotation within a casing containing a gas which may be held at an elevated temperature or pressure. A plurality of vanes is disposed within the pressure vessel. The pressure vessel has an inlet, a first phase outlet and a plurality of second phase outlets disposed radially outwardly of the first phase outlet with respect to a separator axis. A regulator is provided in the form of pressure-activated nozzles to regulate flow through the second phase outlets. In use, a mixture of solids and liquid is fed into the pressure vessel and the pressure vessel is spun within the gas causing solids to accumulate in the vicinity of the second phase outlets. The pressure-activated nozzles are repeatedly opened and closed to expel the accumulated solids.Type: GrantFiled: October 25, 2011Date of Patent: September 8, 2015Assignee: Specialist Process Technologies LimitedInventors: David J. Parkinson, Kevin E. Collier

Patent number: 8834716Abstract: A water treatment system, for example for treating grey water from domestic appliances comprises a water treatment device containing a filter media through which the water passes to remove particulates and bio-matter. The device has a lid provided with a spraying device. The spraying device may, for example, receive treated water along a line, possibly with the addition of an anti-foaming agent. Operating of the spraying device thus serves to collapse any foam generated within the water treatment device. Filter media can be cleaned periodically in a cyclone, after being drawn up through a pipe by means of a jet pump, receiving treated water along a line. Treated water is stored in a storage tank for subsequent use.Type: GrantFiled: April 7, 2010Date of Patent: September 16, 2014Assignee: Aquacyc LimitedInventors: David J. Parkinson, James E. Delves, Kam L. Wong

Patent number: 8794448Abstract: A separator device comprises a cylindrical separation chamber within which a motor-driven rotor is situated. The rotor has vanes. In operation, an inflowing mixture enters through an inlet and is subjected to centrifugal force imposed by the rotation of the rotor. A lighter liquid fraction leaves through an annular outlet, and a heavier liquid fraction leaves through an annular outlet. Solids pass through a screen to a region where rotational flow is reduced or absent. The solids in the region are fluidized by liquid passing through the screen, and are extracted from outlets. Control means is provided to control operation of the device in response to changes in the incoming mixture.Type: GrantFiled: December 17, 2008Date of Patent: August 5, 2014Assignee: Specialist Process Technologies LimitedInventors: Kevin E. Collier, David J. Parkinson

Patent number: 8201139Abstract: A framework for generating a semantic interpretation of natural language input includes an interpreter, a first set of types, and a second set of types. The interpreter is adapted to mediate between a client application and one or more analysis engines to produce interpretations of the natural language input that are valid for the client application. The first set of types is adapted to define interactions between the interpreter and the one or more analysis engines. The second set of types is adapted to define interactions between the interpreter and the client application.Type: GrantFiled: September 15, 2004Date of Patent: June 12, 2012Assignee: Microsoft CorporationInventors: Su Chin Chang, Ravi C.

Patent number: 8114283Abstract: A separator for separating or partially separating oil, water, gas and solids from hydrocarbon production well fluids comprises a vessel and a cyclone contained within the vessel. An inlet passage passes through a wall of the vessel and into the cyclone, the inlet passage having means for causing the flow to rotate within the cyclone. A first outlet passage for an oil rich phase extends from a position within the cyclone and substantially on a central axis of the cyclone; a second outlet passage for a water phase extends from a base of the vessel; and a third outlet passage for the solids extends from a lower end of the cyclone.Type: GrantFiled: February 22, 2006Date of Patent: February 14, 2012Assignee: DPS Bristol (Holdings) LimitedInventor: David J.
