20080087165 - Method and apparatus for extracting carbon dioxide from air: A method and apparatus for extracting CO2 from air comprising an anion exchange material formed in a matrix exposed to a flow of the air, and for delivering that extracted CO2 to controlled environments. The present invention contemplates the extraction of CO2 from air using conventional extraction methods or by... Agent: Hayes Soloway P.C.

20080087166 - Process for refining nitrogen trifluoride gas using alkali earth metal exchanged and impregnated zeolite: Disclosed herein are a process for the refinement of nitrogen trifluoride gas and an adsorbent therefor. A nitrogen trifluoride (NF3) gas including carbon tetrafluoride (CF4) as an impurity is permeated into a bed of zeolite 3 A, 4A or 5 A which undergoes ion exchange and impregnation with alkali earth... Agent: Dickstein Shapiro LLP

20080083329 - Method of in-line purification of cvd reactive precursor materials: We have devised an apparatus useful for and a method of removing impurities from vaporous precursor compositions used to generate reactive precursor vapors from which thin films/layers are formed under sub-atmospheric conditions. The method is particularly useful when the layer deposition apparatus provides for precise addition of quantities of different... Agent: Shirley L. Church, Esq.

20080083330 - Method for separation of molecular/atomic/ionic mixtures: Disclosed herein is an improved method for the separation of molecular/atomic/ionic mixtures. An efficient process for separation of multicomponent mixtures (including binary mixtures) is the object of the invention. Both the levitation effect and blow-torch effect are used simultaneously for separation of mixtures achieve a high degree of separation using... Agent: Foley And Lardner LLP Suite 500

20080078290 - Membrane: A membrane suitable for separating a gas, in particular carbon dioxide, from a gas mixture containing the gas is provided by a blend of polyvinyl alcohol (PVA) and polyvinylamine (PVAm).... Agent: Gardner Groff Greenwald & Villanueva. PC

20080078293 - Removing method and apparatus for high-melting point compound, solvent recovering method and solvent recovering apparatus: A reducing agent removal line comprises a heat exchanger, an air supply line and a cleaning liquid supply line. The cleaning liquid supply line feeds cleaning liquid into a first passage chamber. The air supply line supplies mixed air of after-drying air containing high-melting point additive and additive containing air... Agent: Sughrue Mion, PLLC
