Patent number: 8653272Abstract: A series of heteroaryl-substituted fused pyridine derivatives, in particular heteroaryl-substituted thieno[3,2-6]pyridine derivatives, being selective inhibitors of PO kinase enzymes, are accordingly of benefit in medicine, for example in the treatment of inflammatory, autoimmune, cardiovascular, neurodegenerative, metabolic, oncological, nociceptive or ophthalmic conditions.Type: GrantFiled: October 21, 2009Date of Patent: February 18, 2014Assignee: UCB Pharma S.A.Inventors: Kerry Jenkins, Christopher James Lock, Andrew James Ratcliffe

Patent number: 8453744Abstract: A modulator is disclosed for creating a pressure pulse in a fluid-filled well. The modulator comprises a tool body on which a plurality of extendable arms are mounted. The arms may be retracted into a stowed position substantially adjacent the tool body, or may be extended to meet the wall of the borehole. The arms are preferably resilient bowsprings that may be flexed outwards from the tool by means of an actuator pushing on at least one end of the springs. A flexible valve sleeve or bag is suspended between the arms and cooperates with a valve mounted adjacent the sleeve on the tool body. The valve sleeve creates a fluid-flow path through the valve, and in operation, the valve closes one end of the valve sleeve to create the pressure pulse. Sealing of the valve sleeve against the wall of the well is a result of the fluid pressure inflating the sleeve against the well wall. As a result, sealing takes place over an extended area of the bag and is dynamically responsive to changes in fluid flow or pressure.Type: GrantFiled: November 18, 2009Date of Patent: June 4, 2013Assignee: Sondex Wireline LimitedInventors: John Buss, Charles William Donkin, Ian Hitchcock, William Peter Stuart Bruges, Roy Mowatt, James Ratcliffe, Anthony Webb

Patent number: 7730087Abstract: A method of answering a query includes deconstructing documents into path segments. Identical path segments from different documents are arranged contiguously to form a set of partitions, where each partition has identical path segments. The structure of a query is then analyzed to find a match with a document. Based upon the analysis, a sub-set of partitions is selected for searching. Content from the query is compared to content within the sub-set of partitions to identify matched content. The matched content has associated structural attributes. The matched content structural attributes are compared to the structure of the query to identify an answer to the query.Type: GrantFiled: February 28, 2003Date of Patent: June 1, 2010Assignee: Raining Data CorporationInventors: Jeff Dexter, Allen James Ratcliffe, Eric Soirot
