Patent number: 7470350Abstract: A process for light water detritiation which includes the steps of water distillation for tritium stripping and enriching, followed by chemical conversion of tritium enriched water to elemental hydrogen, and finally by one or more thermal diffusion columns for final tritium enrichment. The combination of process steps takes advantage of water distillation large throughput capability at low tritium concentration with the simplicity of thermal diffusion for small throughput final tritium enrichment. The water distillation front-end and the thermal diffusion back end processes are compatible with any intermediate chemical conversion process such as electrolysis or water gas shift reaction to convert tritiated water to elemental hydrogen.Type: GrantFiled: April 20, 2007Date of Patent: December 30, 2008Assignee: GE Healthcare UK LimitedInventors: Ian Richard Bonnett, Anthony Busigin

Patent number: 7470351Abstract: A system for producing metal particles using a discrete particle electrolyzer cathode, a discrete particle electrolyzer cathode, and methods for manufacturing the cathode. The cathode has a plurality of active zones on a surface thereof at least partially immersed in a reaction solution. The active zones are spaced from one another by between about 0.1 mm and about 10 mm, and each has a surface area no less than about 0.02 square mm. The cathode is spaced from an anode also at least partially immersed in the reaction solution. A voltage potential is applied between the anode and cathode. Metal particles form on the active zones of the cathode. The particles may be dislodged from the cathode after they have achieved a desired size. The geometry and composition of the active zones are specified to promote the growth of high quality particles suitable for use in metal/air fuel cells. Cathodes may be formed from bundled wire, machined metal, chemical etching, or chemical vapor deposition techniques.Type: GrantFiled: April 24, 2003Date of Patent: December 30, 2008Assignee: Teck Cominco Metals Ltd.Inventors: Stuart I.

Patent number: 7470352Abstract: Sensor arrangement having row and column lines arranged in first and second directions, respectively, sensor arrays arranged in crossover regions of the row and column lines, a detector, and a decoding device. The sensor arrays have a coupling device for electrically coupling respective row and column lines, and a sensor element to influence electric current flow through the coupling device. The detector is electrically coupled to a respective end section of at least a portion of the row and column lines, and detects a respective accumulative current flow from the individual electrical current flows provided by the sensor arrays of the respective lines. The decoding device is coupled to the row and column lines, and evaluates at least a portion of the accumulative electric current flows fed to the decoding device via the row and column lines to determine at which of the sensor elements a sensor signal is present.Type: GrantFiled: April 16, 2004Date of Patent: December 30, 2008Assignee: Infineon Technologies AGInventors: Bjorn-Oliver Eversmann, Christian Paulus, Guido Stromberg, Roland Thewes

Patent number: 7470354Abstract: A method for electrolytic production of aluminium metal from an electrolytic (3) including aluminium oxide, by performing electrolysis, with at least one inert anode (1) and at least one cathode (2) thus forming part of an electorwinning cell. The anode evolves oxygen gas and the cathode has aluminium discharged onto it in the electrolysis process, where the oxygen gas enforces an electrolyte flow pattern. The oxygen gas is directed to flow into anode grooves and is drained away from the interpolar room, thereby establishing an electrolyte flow pattern between the electrodes (1) and (2) and between over the anodes (1). The invention also concerns and anode assembly and an electrowinning cell.Type: GrantFiled: August 15, 2003Date of Patent: December 30, 2008Assignee: Norsk Hydro ASAInventors: Odd-Arne Lorentsen, Ole-Jacob Siljan, Stein Julsrud

Patent number: 7470355Abstract: A process for electrochemically reducing a metal oxide, such as titania, in a solid state in an electrochemical cell that includes a bath of molten electrolyte, a cathode, and an anode, which process includes the steps of: a) applying a cell potential across the anode and the cathode that is capable of electrochemically reducing the metal oxide supplied to the molten electrolyte bath, b) continuously or semi-continuously feeding the metal oxide in powder and/or pellet form into the molten electrolyte bath, c) transporting the powders and/or pellets along a path within the molten electrolyte bath and reducing the metal oxide as the metal oxide powders and/or pellets move along the path, and d) continuously or semi-continuously removing metal from the molten electrolyte bath. Also disclosed and claims is an electrochemical cell for carrying out this process.Type: GrantFiled: December 12, 2003Date of Patent: December 30, 2008Assignee: BHP Billiton Innovation Pty LtdInventors: Steve Osborn, Ivan Ratchev, Les Strezov, Greg Rigby

Patent number: 7470356Abstract: A system, device, and method include a cell-powered first electronic device for monitoring two or more electrolytic cells is powered using electrical potential imposed across the electrolytic cells. The potential is voltage-boosted to accomplish this task. If the electrical potential imposed across the cells is insufficient, the device can also be battery-powered. In any event, this device is in communication with one or more sensors in the electrolytic cells, as well as a second electronic device, and the first and second electronic devices wirelessly communicate. More specifically, the first electronic device wireless transmits data signals to the second electronic device, which receives the same. The first and second electronic devices are physically remote from one another, and they communicate over a private or public network, preferably using spread spectrum technology.Type: GrantFiled: June 8, 2006Date of Patent: December 30, 2008Assignee: Kennecott Utah Copper CorporationInventors: Eugene Yanjun You, Daniel Kang Kim

Patent number: 7470359Abstract: The method enables the antihydrate compounds contained in a condensed-hydrocarbon liquid feedstock arriving through pipe 1 to be extracted. The liquid feedstock is brought into contact, in zone ZA, with a non-aqueous ionic liquid having the general formula Q+ A31 , where Q+ designates an ammonium, phosphonium, and/or sulfonium cation, and A31 designates an anion able to form a liquid salt. The antihydrate compounds in the liquid hydrocarbon feedstock evacuated through pipe 2 are eliminated. The ionic liquid charged with antihydrate compounds is evacuated through pipe 3, then introduced into evaporator DE to be heated in order to evaporate the antihydrate compounds. The regenerated ionic liquid is recycled through pipes 8 and 9 to zone ZA. The antihydrates are evacuated through pipe 7a.Type: GrantFiled: February 14, 2005Date of Patent: December 30, 2008Assignee: Institut Francais du PetroleInventors: Renaud Cadours, Fabrice Lecomte, Lionel Magna, Cécile Barrere-Tricca
