Each aggregation surface of the plurality of aggregation surfaces is oriented such that a difference between a flow direction of the gases prior to impinging on the aggregation surface and a flow direction of the gases after impinging on the aggregation surface is at least approximately 90°, wherein particulates in gases impinging on the aggregation surfaces aggregate on the surfaces.Type: GrantFiled: June 1, 2006Date of Patent: February 2, 2010Assignee: Automotive Systems Laboratory, Inc.Inventors: David M. McCormick, Robert M. Hardenburg, Bernardo V. Vergara

Publication number: 20100005825Abstract: Devices and methods for sterilizing bottled water coolers and water dispensed therefrom. According to certain embodiments, the invention includes a bottled water cooler, which comprises a water bottle, an exterior cabinet, a cold tank, a bottle receptacle located on top of the cold tank that is configured to receive the water bottle in an inverted position, and an ozone generator. The ozone generator is capable of dispensing ozone gas within the space located above a volume of water contained within the cold tank, such that the ozone gas will be effective to sterilize the interior portions of the cold tank located above the volume of water.Type: ApplicationFiled: February 28, 2009Publication date: January 14, 2010Inventor: George M. Yui

Patent number: 7645382Abstract: A method of converting biological material into energy resources includes transmitting biological material to a pulsed electric field (PEF) station, and applying a PEF to the biological material within a treatment zone in the PEF station to generate treated biological material. The method also includes transmitting the treated biological material to a biogenerator, and processing the treated biological material in the biogenerator to produce an energy resource. A converter may carry out this process, and may include the PEF station and the biogenerator.Type: GrantFiled: March 23, 2009Date of Patent: January 12, 2010Assignee: OPENCELL LLCInventors: Michael T. Gallagher, Jeffrey Held, Satya P. Chauhan, Anthony J. Tomasello

Publication number: 20090297417Abstract: Disclosed are methods and apparatus enabling the efficient utilization of urea for purposes such as selective catalytic reduction (SCR) of NOx, which enable feeding urea to a chamber designed to efficiently and completely gasify the urea to enable ammonia feed. Preferably, aqueous urea is fed to a gasification chamber, which is also fed with heated gases. An injector means, capable of distributing the aqueous urea as fine droplets, is positioned centrally of a gas distribution plate in the chamber. An arrangement of spaced holes in the gas distribution plate provides higher gas velocity in the vicinity of the injector means than near the walls of the chamber. Uniform gas distribution without equipment fouling is achieved.Type: ApplicationFiled: May 27, 2009Publication date: December 3, 2009Applicant: FUEL TECH, INC.Inventors: William H. Sun, John M. Boyle, Ronald A. Lau

Patent number: 7611667Abstract: A sterilization system that includes a sensor for determining the concentration of a liquid sterilant in a sterilant fluid. The sterilant fluid is comprised of a blend of sterilant fluids from a plurality of sterilant supplies. The concentration of the liquid sterilant differs in each of the sterilant supplies. The sensor allows a controllable concentration of liquid sterilant to be supplied to a vaporizer.Type: GrantFiled: September 6, 2007Date of Patent: November 3, 2009Assignee: STERIS CorporationInventor: Michael A. Centanni

Patent number: 7595020Abstract: An improved singlet oxygen generator (SOG) and method of using gas phase electronically excited states of oxygen for bio-medical and chemical treatment applications are disclosed. According to the invention, both gas phase O2(1?) and O2(1?) are used for medical treatment, sterilization, and deactivation of biological and chemical agents, including diseased tissue and biological and chemical weapons. The improved SOG is compact and scalable, portable, capable of operating in a zero-gravity or low gravity environment, may use gaseous diluent or buffer gas, and is capable of operating at pressures as high as one atmosphere. The SOG is capable of operating within a short distance of the target site for the electronically excited states of oxygen, which are delivered to the target site via a conduit. The SOG and delivery system provide higher yields of electronically excited oxygen with longer lifetimes suitable for bio-medical applications.Type: GrantFiled: March 8, 2004Date of Patent: September 29, 2009Assignee: KSY CorporationInventor: George Emanuel
