Patent number: 7252709Abstract: The invention detailed herein comprises a family of multifunctional acrylate oligomers which are useful as pigment grinding vehicles for use in radiation-curable coating formulations. The multifunctional acrylate resins are formed by the reaction of acrylate monomers and oligomers with ?-keto esters (e.g., acetoacetates), ?-diketones (e.g., 2,4-pentanedione), ?-keto amides (e.g., acetoacetanilide, acetoacetamide), and/or other ?-dicarbonyl compounds or Michael “donors” that can participate in the Michael addition reaction.

In one embodiment an isolated repelling or repelling electrode is positioned in the plasma duct downstream of the deflecting electrode where the tangential component of a deflecting magnetic field is strongest, connected to the positive pole of a current source which allows the isolated electrode current to be varied independently and increased above the level of the anode current. The deflecting electrode may serve as a getter pump to improve pumping efficiency and divert metal ions from the plasma flow.Type: GrantFiled: November 13, 2003Date of Patent: August 7, 2007Assignee: G & H Technologies, LLCInventor: Vladimir I.

Patent number: 7252747Abstract: A composite proton exchange membrane and method of manufacturing the same. The composite proton exchange membrane comprises a proton exchange membrane which has been modified by replacing membrane protons in desired areas of the membrane with a cationic polymer. The cationic polymer is preferably formed by introducing a quaternary salt monomer into the membrane and then effecting the polymerization of the monomer. The modified areas of the proton exchange membrane exhibit increased strength, reduced water and gas permeability, reduced proton conductivity and reduced acidity. Accordingly, by modifying the periphery of the membrane, one can obtain an integral sealing edge for the membrane, and by modifying certain interior regions of the membrane, one can divide the membrane into a plurality of sealed segments.Type: GrantFiled: October 5, 2006Date of Patent: August 7, 2007Assignee: Giner Electrochemical Systems, LLCInventors: Robert C.

Patent number: 7252750Abstract: A dual contact ring for contacting a patterned surface of a wafer and electrochemical plating of a metal on the patterned central region of the wafer and removing the metal from the outer, edge region of the wafer. The dual contact ring has an outer voltage ring in contact with the outer, edge region of the wafer and an inner voltage ring in contact with the inner, central region of the wafer. The outer voltage ring is connected to a positive voltage source and the inner voltage ring is connected to a negative voltage source. The inner voltage ring applies a negative voltage to the wafer to facilitate the plating of metal onto the patterned region of the wafer. A positive voltage is applied to the wafer through the outer voltage ring to remove the plated metal from the outer, edge region of the substrate.Type: GrantFiled: September 16, 2003Date of Patent: August 7, 2007Assignee: Taiwan Semiconductor Manufacturing Co., Ltd.Inventors: Chi-Wen Liu, Jung-Chih Tsao, Ke-Wei Chen, Ying-Lang Wang

Patent number: 7252752Abstract: A method and apparatus for contaminant separation utilizes an interleaved array of oppositely charged electrode plates for fluid treatment. Spacing between the parallel electrode plates is graduated so that the volume of the cavities between the opposing electrodes provides varying levels of treatment of a broad range of contaminants from a variety of fluid columns. A fluid flow path extending substantially orthogonal to the direction of the electrical field established between opposing electrode plates provides a feed stream with exposure to the varying levels of electrical charges between the electrode plates. The method and apparatus provide an effective means of contaminant separation by a device having a small footprint and requiring low amounts of electrical energy.Type: GrantFiled: March 27, 2006Date of Patent: August 7, 2007Inventor: Herbert William Holland

Patent number: 7252756Abstract: A process is disclosed for the production of refinery transportation fuel or components for refinery blending of transportation fuels having a reduced amount of sulfur and/or nitrogen-containing impurities. The process involves contacting a hydrocarbon feedstock containing the above impurities with an immiscible phase containing hydrogen peroxide and acetic acid in an oxidation zone to selectively oxidize the impurities. After a gravity phase separation, the hydrocarbon phase containing any remaining oxidized impurities, is passed to an extraction zone wherein aqueous acetic acid is used to extract a portion of any remaining oxidized impurities. A hydrocarbon stream having reduced impurities can then be recovered. The acetic acid phase effluents from the oxidation and the extraction zones can then be passed to a common separation zone for recovery of the acetic acid and for optional recycle back to the oxidation and extraction zones.Type: GrantFiled: December 18, 2002Date of Patent: August 7, 2007Assignee: BP Corporation North America Inc.Inventors: William H.
