Patent number: 7232550Abstract: A fluid-burning lamp that delivers a fragrance(s) and is aesthetically pleasing. The fluid-burning lamp includes a fragrance-dispensing element that contains a material that slowly melts and forms a liquid pool when the lamp is lit. The slow-melting material gives the fluid-burning lamp the appearance of a traditional wax candle, when the lamp is viewed from the top. Other elements of the fluid-burning lamp include a fluid container for holding a combustible fluid to be used as fuel for the burn, and a wick assembly containing a wick having a lower portion that extends into the combustible fluid. The fluid container for holding the combustible fluid may also hold various immersions, such as, for example, fruits, colored marbles, leaves, seeds, sprigs, or flowers, in order to provide the ultimate in flexibility for home décor.Type: GrantFiled: September 16, 2002Date of Patent: June 19, 2007Assignee: TRI Tech Laboratories, Inc.Inventors: Ronald W. Rodgers, Steven L. Fullerton, Jennifer M. Smith

Patent number: 7232552Abstract: The apparatus for decomposing PFCs includes an external electrode unit which is coupled to a reference voltage and which defines a flow space for the flow of the PFCs, and an internal electrode unit which is located within the flow space of the external electrode unit so as to define a reaction space between the internal electrode unit and the external electrode unit. The apparatus is also equipped with a voltage supply unit which applies an alternating voltage to the internal electrode unit which is of sufficient voltage and frequency to generate an electron beam within the reaction space which is capable of decomposing the PFCs.Type: GrantFiled: April 28, 2003Date of Patent: June 19, 2007Assignees: Samsung Electronics Co., Ltd., Forhuman Co., Ltd.Inventors: Seung-ki Chae, Sang-gon Lee, In-ju Lee, Kyoung-hye Lee, Yong-hee Lee, Jin-ok Jung, Young-jo Shin

Patent number: 7232554Abstract: A process for the recovery of arsenic trioxide from acid solutions, particularly the aqueous acid effluent produced by a gas-washing process in the pyrometallurgy of copper sulfide ores is provided. Generally, the process comprises concentrating the acid solution in one or more evaporators in series; crystallizing arsenic contained in the concentrated solution as arsenic trioxide crystals; filtering the crystallized solution to obtain a solid phase comprising impure arsenic trioxide crystals; and purifying the solid phase to obtain a purified crystal product comprising arsenic trioxide. The process produces a commercially salable arsenic trioxide product without producing any solid or liquid residues subject to special handling or treatment regulations.Type: GrantFiled: December 14, 2001Date of Patent: June 19, 2007Assignee: Barrick Gold CorporationInventors: Jose Mendoza Videla, Jorge Balanda Andina, Hector Gallegos Cisternas

Patent number: 7232557Abstract: The invention describes a method of preparing magnetic ferrites from layered precursors in which Fe2+ is first introduced into the layers of layered double hydroxides (LDHs) in order to prepare Me-Fe2+—Fe3+ LDHs, and then by utilizing the easily oxidized nature of Fe2+, binary or multi-component ferrite materials containing Fe3+ in a single crystalline phase can be prepared. Values of the saturation magnetization of ferrites prepared by the method are significantly increased compared with ferrites prepared by traditional methods. Because the metal elements in the layered precursor have the characteristics of a high degree of dispersion, high activity and small particle size (average particle size 40-200 nm), no milling is required before calcination, thus simplifying the production process, shortening the production period, reducing capital investment in equipment and economizing on energy costs. In addition, the method does not corrode production equipment and does not pollute the environment.Type: GrantFiled: January 21, 2005Date of Patent: June 19, 2007Assignee: Beijing University of Chemical TechnologyInventors: Xue Duan, Feng Li, Junjie Liu

Patent number: 7232558Abstract: Solid, shaped and fired fibers of Ti4O7 and Ti5O9 are made by firing TiO2 fibers in a reducing atmosphere. In a first aspect, the TiO2 fibers are made by extruding into air a viscous TiO2 gel and heat treating the resulting green fibers to remove solvent, decompose and to volatilize undesired constituents to form electrically conductive, refractory fibers of Ti4O7 and Ti5O9. In a second aspect, solid, shaped and fired fibers of Ti4O7 and Ti5O9 are made by firing extruded fibers from mixtures of TiO2.Type: GrantFiled: January 9, 2004Date of Patent: June 19, 2007Assignee: Advanced Power Devices, Inc.Inventors: Richard E. Tressler, James H. Adair, David L. Shelleman, Julie M. Anderson
