Patent number: 7818959Abstract: One aspect of the invention relates to a power generation system that has an internal combustion engine that operates in a low temperature combustion mode to produce an engine exhaust that is low in NOx and particulate matter. The exhaust is treated by a fuel cell to remove organic compounds and CO while producing useful power. Another aspect of the invention relates to controlling the adiabatic flame temperature by EGR drawing from upstream of the fuel cell. A further aspect of the invention relates to treating engine exhaust with a reducing catalyst and then with a fuel cell. A still further aspect of the invention relates to treating exhaust with an intermediate temperature solid oxide fuel cell. A further aspect of the invention relates to a system equipped with a valve allowing exhaust to selectively bypass a fuel cell.Type: GrantFiled: September 17, 2004Date of Patent: October 26, 2010Assignee: Eaton CorporationInventors: Haoran Hu, Thomas Stover, Timothy J. Morscheck, Kathryn A. Miles, Patrick M. Watts, Diane C. Wiersma

Patent number: 7648785Abstract: One aspect of the invention relates to a clean power generation system in which an internal combustion engine is operated to produce shaft power and an exhaust stream. The exhaust stream is processed by a fuel cell. Fluctuations in power demand are met, at least in part, by increasing or decreasing power output from the fuel cell and/or power uptake or output from a power storage device. The engine can operate at a relatively constant rate, providing a steady exhaust stream, which facilitates pollution control and fuel cell operation. According to another aspect of the invention, the exhaust of an engine is treated with a fuel cell having an electrolyte that conducts protons. In addition to removing pollutants from the exhaust while generating useful power, the fuel cell can provide a supply of low acidity water. The water can be used in the fuel reformer.Type: GrantFiled: September 17, 2004Date of Patent: January 19, 2010Assignee: Eaton CorporationInventors: Haoran Hu, Thomas Stover, Timothy J.

Publication number: 20060059892Abstract: One aspect of the invention relates to a power generation system comprising an internal combustion engine that operates, generally by limiting the adiabatic flame temperature, to produce an engine exhaust that is low in NOx and particulate matter. The exhaust is treated by a fuel cell to remove organic compounds and CO while producing useful power. Another aspect of the invention relates to controlling the adiabatic flame temperature by EGR drawing from upstream of the fuel cell.

Patent number: 6700082Abstract: A plunger mechanism provides for automatic tripping of a circuit breaker upon the opening of a cover of electrical equipment connected adjacent to the circuit breaker. One end of the plunger mechanism protrudes from the circuit breaker's housing adjacent to the cover, and the other end of the plunger mechanism engages the latch within the trip mechanism of the circuit breaker. Upon opening the cover, the plunger is depressed by the cover, rotating the latch, thereby tripping the circuit breaker.Type: GrantFiled: December 20, 2002Date of Patent: March 2, 2004Assignee: Eaton CorporationInventors: Jeffrey S. Gibson, Craig A. Rodgers, John A. Wafer, Kathryn A. Miles

Patent number: 6204465Abstract: A molded case circuit breaker has paddles on the trip bar to utilize the arc gases generated during interruption to speed operation of the latchable operating mechanism and to protect the trip mechanism from debris in the arc gases. Alternatively, or in addition, lateral projections can be provided on the crossbar for similar purposes.Type: GrantFiled: April 3, 2000Date of Patent: March 20, 2001Assignee: Eaton CorporationInventors: Lance Gula, Richard Paul Malingowski, Kathryn Miles Palmer, William Ellsworth Beatty, Jr.

Patent number: 5944859Abstract: A filter element for separating fine dirty particles from a hot gas. The filter element comprises a first porous wall and a second porous wall. Each porous wall has an outer surface and an inner surface. The first and second porous walls being coupled together thereby forming a substantially closed figure and open at one end. The open end is formed to be coupled to a hot gas clean up system support structure. The first and second porous walls define a channel beginning at the open end and terminate at the closed end through which a filtered clean gas can flow through and out into the clean gas side of a hot gas clean up system.Type: GrantFiled: May 6, 1996Date of Patent: August 31, 1999Assignee: Siemens Westinghouse Power CorporationInventors: Thomas Edwin Lippert, Kathryn Miles Palmer, Gerald Joseph Bruck, Mary Anne Alvin, Eugene E. Smeltzer, Dennis Michael Bachovchin
