Patent number: 7257568Abstract: The present invention provides a search method and system for matching a commodity to one or more applications for using the commodity. A plurality of properties associated with the commodity are identified. A collection of documents for searching for a plurality of combinations of the identified properties is also defined, wherein the combination includes a single property or multiple properties. The defined collection of documents is searched for all occurrences or indications of the combination of properties, and the hits are retrieved for those documents that include one or more of the identified properties. The hits are then associated with one or more subclasses of a classification scheme, and reviewed for those hits that include the identified properties of the commodity, but that need not otherwise identify the commodity per se.Type: GrantFiled: October 16, 2002Date of Patent: August 14, 2007Assignee: Sizatola, LLCInventors: Steven O. Kimbrough, Ian MacMillan, John Ranieri

Publication number: 20070106662Abstract: A method of managing information comprises generating a categorized document base. Generating the document base comprises providing a pre-existing classification of things other than documents, providing a source collection of documents, and automatically assessing the documents using Information Retrieval techniques to assign at least some of the documents to one or more taxa of the classification. For each taxon in the classification one or more numerical scores are assigned, based at least in part on a composition, makeup or constitution of the documents assigned to the taxon of the categorized document base.Type: ApplicationFiled: October 25, 2006Publication date: May 10, 2007Applicant: Sizatola, LLCInventors: Steven Kimbrough, Ian MacMillan, John Ranieri, James Thompson

Publication number: 20040113324Abstract: A polyolefin plaque is made by hot compaction of an assembly of fibres of the oriented polymer. It has been found to be beneficial to subject the fibres to a prior crosslinking process. Hot compaction is then less temperature-sensitive and produces plaques with excellent hot strength properties. Preferably the fibres have been subjected to prior stages of irradiation and annealing, both in a non-oxidising environment, for example acetylene.Type: ApplicationFiled: November 21, 2003Publication date: June 17, 2004Applicant: BTG Internationl LimitedInventors: Richard Albert Jones, Ian MacMillan Ward, Peter John Hine, Mark James Bonner

Publication number: 20020003317Abstract: A polyolefin plaque is produced by hot compaction of an assembly of melt spun oriented fibers. It has been found that good compaction can be achieved at relatively low compaction pressures, less than 10 MPa. Compaction can be carried out in an autoclave, rather than in a hot compaction press, and the mechanical properties of plaques so produced range from good to excellent.Type: ApplicationFiled: April 2, 1999Publication date: January 10, 2002Inventors: IAN MACMILLAN WARD, PETER JOHN HINE, MARK JAMES BONNER

Patent number: 6277773Abstract: Polymeric monoliths having high stiffness and strength can be produced by heating an assembly of polymer fibres under a contact pressure to a temperature at which a proportion of the fibre is selectively melted and then compressing the assembly. Preferably at least 5% of the polymer is melted so that on compression the molten materials fills the voids within the assembly. The use of polyolefin fibres especially melt spun polyethylene fibres is preferred. The products are useful e.g. as orthodontic brackets, bone prostheses and in body armour.Type: GrantFiled: December 13, 1999Date of Patent: August 21, 2001Assignee: BTG International LimitedInventors: Ian Macmillan Ward, Peter John Hine, Keith Norris

Patent number: 6278707Abstract: A communication system includes an interface between two networks, for example the public telephone system and an IP-based network. The system includes a modem bank which receives bearer channel inputs and provides outputs to the second network. A protocol converter interfaces with a signaling network such as a common channel signaling (CCS) network (e.g., an Signaling System 7 network). The protocol converter communicates signaling information to the modem bank. A resource manager is coupled to the protocol converter and includes a memory which stores status information relating to the system.Type: GrantFiled: October 1, 1998Date of Patent: August 21, 2001Assignee: MCI communications CorporationInventors: Ian MacMillan, Frederick A. Sherman, Ranga Dendi, Dale Gil Read

Patent number: 5910346Abstract: Tubular workpieces of oriented polymers such as polyethylene polyester and PVC are formed by drawing a workpiece over an expanding former in the absence of any force perpendicular to the axis of the workpiece. The processes do not require the use of any liquid lubricant. They enable greater degrees of expansion and hence orientation in the direction perpendicular to the axis to be achieved and result in products of improved appearance and strength.Type: GrantFiled: June 7, 1995Date of Patent: June 8, 1999Assignee: BTG International LimitedInventors: Ian MacMillan Ward, Gordon Craggs, Alan Selwood, Ajay Kumar Taraiya

Patent number: RE37700Abstract: A bulk ionically conductive polymer gel is prepared by dissolving a salt such as lithium trifluoromethanesulphonate (which would provide lithium ion conductors) in an organic compound such as N-formylpiperidine. The organic compound dissolves the salt at 20° C. but is not a solvent at 20° C. though it is at 215° C.) for polyethylene terephthalate. The last-named is a crystallizable polymer which is added in a minor amount at a high temperature to the other components and provides the required mechanical rigidity for the product at lower temperatures.Type: GrantFiled: June 17, 1999Date of Patent: May 14, 2002Assignee: BTG International LimitedInventors: Hugh Vyvyan St. Aubyn Hubbard, James Eric McIntyre, Victor Rogers, Ian Macmillan Ward
