Patent number: 7252697Abstract: A method for making controlled-release ammonium phosphate fertilizer has the following acts of: cracking, pulverizing, blending, aging, drying, and adding release-controlling materials into an ammonium phosphate slurry during preparing processes or adding release-controlling materials in achieved ammonium phosphate powder. Selectively, sulfuric acid is added into the mixture of the release-controlling materials and the ammonium phosphate slurry or ammonium phosphate powder to acidify the mixture. In this method, the release-controlling material combines with the ammonium phosphate by chemical bonding to control the release of nitrogen and phosphorus nutrients to enhance the use efficiency and elongate fertilization effect of the controlled-release ammonium phosphate fertilizer.Type: GrantFiled: July 2, 2003Date of Patent: August 7, 2007Assignee: South China Agricultural UniversityInventors: Zongwen Liao, Song Bo, Xiaoyun Mao, Ping-Xiao Guan

Patent number: 7252698Abstract: The present invention provides nanoprisms etched to generate triangular framework structures. These triangular nanoframes possess no strong surface plasmon bands in the ultraviolet or visible regions of the optical spectrum. By adding a mild reducing agent, metal ions remaining in solution can be reduced, resulting in metal plating and reformation of nanoprisms. The extent of the backfilling process can be controlled, allowing the formation of novel nanoprisms with nanopores. This back-filling process is accompanied by a regeneration of the surface plasmon bands in the UV-visible spectrum.Type: GrantFiled: March 15, 2004Date of Patent: August 7, 2007Assignee: Northwestern UniversityInventors: Chad A. Mirkin, Gabriella Métraux, YunWei Charles Cao, Rongchao Jin

Patent number: 7252699Abstract: Continuous, conducting metal patterns can be formed from metal nanoparticle containing films by exposure to radiation (FIG. 1). The metal patterns can be one, two, or three dimensional and have high resolution resulting in feature sizes in the order of micron down to nanometers. Compositions containing the nanoparticles coated with a ligand and further including a dye, a metal salt, and either a matrix or an optional sacrificial donor are also disclosed.Type: GrantFiled: December 17, 2001Date of Patent: August 7, 2007Assignee: The Arizona Board of RegentsInventors: Joseph W. Perry, Seth R. Marder, Francesco Stellacci

Patent number: 7252700Abstract: A method and mobile system for cleaning dirty gas from a newly stimulated gas well. The entire system is supported on a trailer or other mobile support so that it can be driven from well site to well site for short-term, post-stimulation use only. The system comprises a gas separator, such as a membrane separator. The system also includes a pretreatment assembly for preparing the gas for the gas separator. The pretreatment assembly may include separators, a heater, a guard vessel and a polishing filter. A chiller or heat exchanger cools the treated gas to a marketable temperature. A generator and a hydraulics plant provide power to the system. Each mobile system will be designed to treat gases with widely different operating conditions varying from well to well.Type: GrantFiled: August 16, 2005Date of Patent: August 7, 2007Inventor: Ronald L. Strahan

Patent number: 7252701Abstract: The invention relates to a method of cleaning an electric filter and to an electric filter. In the method gas containing particles is fed to a chamber (2) of the electric filter. The gas is further fed to gas channels (5) in an emission system (3) provided in the chamber (2). What is brought about is electric charging of the particles in the gas and attachment to the separation electrode (1). Gas purified of particles is removed from the gas channel (5). The separation electrode (1) is shaken with shaker (8) to remove the particles attached to the separation electrode (1) therefrom. In this method, the gas flow is limited in such a gas channel (5) which adjoins the separation electrode (1) to be shaken by the shaker (8) when the separation electrode (1) to be shaken by the shaker (8) is shaken.Type: GrantFiled: June 16, 2004Date of Patent: August 7, 2007Assignee: ALSTOM Technology LtdInventor: Juha Tolvanen

Patent number: 7252702Abstract: A method of hydrogen recovery in refineries and petrochemical operations in which some or all of the feed streams for separate PSA units are combined and utilized as feed for a single PSA unit, and in which some or all of steam reformer product and refinery offgas streams being used as feed streams for separate PSA units are combined and utilized as feed for a single PSA unit. Total hydrogen recovery is increased by maximizing hydrogen recovery from refinery offgases. The load on the steam reformer is reduced by lowering the reformer feed stream. Refinery fuel gas consumption is reduced in the steam reformer furnace. The amount of a PSA feed stream being burned as fuel or sent to flare is reduced. The load on the PSA unit receiving feed from refinery offgases is reduced. The hydrocarbon content and heating value of the tail gas from the PSA unit fed by the steam reformer product stream is enriched.Type: GrantFiled: July 25, 2003Date of Patent: August 7, 2007Assignee: Saudi Arabian Oil CompanyInventor: Ibrahim M. Al-Babtain

Patent number: 7252703Abstract: The direct contact liquid air contaminant control system and method to revitalize air by removal of carbon dioxide and other trace gas contaminants use a direct contact air, liquid scrubber element and stripper element. The scrubber element has two rotor elements rotatably mounted in a housing first for centrifugal separation of an air flow and liquid absorbent mixture which liquid absorbent has absorbed carbon dioxide and trace gas contaminants. Then second for centrifugal separation of an air flow and acid water wash mixture which acid water wash has liquid absorbent and other contaminants. The processed air is then passed through a charcoal bed filter for further removal of contaminants. A rotary contact processor may also be used to reprocess contaminated liquid absorbent for reuse.Type: GrantFiled: June 30, 2003Date of Patent: August 7, 2007Assignee: Honeywell International, Inc.Inventor: Al MacKnight

Patent number: 7252704Abstract: A filter arrangement includes a first filter element having opposite first and second ends; an axial length between the first and second ends; and a plurality of flutes. Each of the flutes has a first end portion adjacent to the first filter element first end, and a second end portion adjacent to the first filter element second end. Selected ones of the flutes are open at the first end portion and closed at the second end portion; and selected ones of the flutes are closed at the first end portion and open at the second end portion. A sleeve member secured to and circumscribing the first filter element. The sleeve member is oriented relative the first filter element to extend at least 30% of the axial length of the first filter element. A seal member pressure flange at least partially circumscribes the sleeve member. The filter arrangement is particularly useful for gas turbine systems. Methods for operating and servicing filter arrangements preferably utilize constructions herein.Type: GrantFiled: February 3, 2006Date of Patent: August 7, 2007Assignee: Donaldson Company, Inc.Inventors: Joseph C.

Patent number: 7252705Abstract: A zinc-rich water-based paint blends a binder and a chelating agent in a zinc slurry. The zinc slurry is blended in an amount of 61.7% by weigh. A potassium as the binder is blended in an amount of 30.0% by weight. A blending quantity of an ion exchange water is decreased as a blending quantity of EDTA-4K as the chelating agent is increased such as 0.2, 0.4, 0.7, 1.4 and 2.4% by weigh as, so that a total quantity becomes 100%.Type: GrantFiled: November 22, 2004Date of Patent: August 7, 2007Assignee: Aisin Kako Kabushiki KaishaInventor: Tatsuya Kano
