Patent number: 8857739Abstract: A combustor for a gas turbine engine is disclosed which is able to operate with high combustion efficiency, and low nitrous oxide emissions during gas turbine operations. The combustor consists of a can-type configuration which combusts fuel premixed with air and delivers the hot gases to a turbine. Fuel is premixed with air through a swirler and is delivered to the combustor with a high degree of swirl motion about a central axis. This swirling mixture of reactants is conveyed downstream through a flow path that expands; the mixture reacts, and establishes an upstream central recirculation flow along the central axis. A cooling assembly is located on the swirler co-linear with the central axis in which cooler air is conveyed into the prechamber between the recirculation flow and the swirler surface.Type: GrantFiled: December 12, 2011Date of Patent: October 14, 2014Assignee: Flexenergy Energy Systems, Inc.Inventors: Yimin Huang, Shaun Sullivan, Brian Finstad, Alexander Haplau-Colan

Patent number: 7565808Abstract: A refrigerator includes a gas flow generator formed with passages providing communication between an annular inlet chamber and a gas flow chamber, so that gas under pressure in the inlet chamber flows through the passages into the gas flow chamber. An energy transfer tube has a cylindrical interior space in communication with the gas flow chamber at one end of the tube and a throttle valve is installed in the energy transfer tube at its opposite end. An acoustic tone at a frequency in the range between about 1 kHz and about 20 kHz is spontaneously generated in the energy transfer tube when gas at a pressure exceeding about 100 psig is supplied to the inlet chamber.Type: GrantFiled: August 5, 2005Date of Patent: July 28, 2009Assignee: GreenCentAire, LLCInventor: Shaun Sullivan

Patent number: 7442239Abstract: A fuel-conditioning skid for an engine. The fuel-conditioning skid includes an inlet that is connectable to a source to receive a flow of fuel containing undesirable compounds. An outlet is connectable to the engine to deliver a flow of fuel that is substantially free of undesirable compounds. An inlet cleaner is in fluid communication with the inlet and is operable to remove a portion of the undesirable compounds. A compressor is in fluid communication with the inlet cleaner to receive the flow of fuel at a first pressure and discharge the flow of fuel at a second pressure. The second pressure is greater than the first pressure. A purifier is in fluid communication with the inlet cleaner to receive the flow of fuel. The purifier is operable to remove substantially all of the remaining undesirable compounds from the flow of fuel.Type: GrantFiled: March 24, 2004Date of Patent: October 28, 2008Assignee: Ingersoll-Rand Energy Systems CorporationInventors: Jeffrey A. Armstrong, Shaun Sullivan, Eric Roslund

Publication number: 20050010477Abstract: A method of optimizing direct marketing campaigns to a pool of potential donors, comprising defining a plurality of segments, wherein each potential donor is a member of no more than one respective segment, defining and associating a respective package with each segment wherein each package is indicative of the material to be sent to members of the respective segment, activating or fixing in time a first segmentation comprised of one or more of the segments, sending the respective package to members of the respective segments, thereafter associating responses with respective segments in a computer database, calculating a response rate and an average gift amount for each respective segment, and creating a new, optimized segmentation based on the responses obtained from the first segmentation. Another method includes means for ranking segments in a hierarchical fashion and optimizing projected return on investment based on an optimized segment hierarchy.Type: ApplicationFiled: July 1, 2004Publication date: January 13, 2005Applicant: Blackbaud, Inc.Inventors: Shaun Sullivan, Paul Gibson, John Holder, Lawrence Mishkin, Andrew Sarosy
