Patent number: 11859544Abstract: In a closed system that recirculates exhaust gas from a gas turbine engine, recirculated exhaust gas should be mixed into inlet gas in a manner that produces a uniform distribution within the mixed gas, while preventing an excessive pressure drop at the point of mixing, and without needing excessive duct length. Otherwise, the performance of the gas turbine engine may be detrimentally affected. Accordingly, a mixer box is disclosed that injects recirculated exhaust gas into a flow path of inlet gas in a uniform manner. The mixer box may comprise mixer(s) that extend the flow path of the recirculated exhaust gas into the flow path of the inlet gas along two axes. Each mixer may comprise surface apertures and/or interior channels designed to promote uniform ejection of the recirculated exhaust gas from the mixers into the flow path of inlet gas.Type: GrantFiled: June 16, 2022Date of Patent: January 2, 2024Assignee: Solar Turbines IncorporatedInventors: John Lockyer, Jiang Luo, Stephen Theron, Stephen Burke

Patent number: 8204881Abstract: Embodiments of the invention provide for various methods and apparatuses for searching bodies of knowledge, such as previously indexed source documents reachable over a network, search results from previous searches, and results from performing meta-searches. Search criteria is received from a client, and the bodies of knowledge are searched based on the search criteria, and search results provided responsive to said searching. Search results may be configured to have associated distillation triggers, where selecting a trigger causes its associated search result to be distilled in real-time. Distilled search results can be indexed into portions of the source document for focused entry, and can also be grouped and analytically presented on mid-menus to allow the user to review distilled data in summary form.Type: GrantFiled: November 29, 2010Date of Patent: June 19, 2012Assignee: Vision Point Services, LLCInventors: Thomas D. Holt, Larry Stephen Burke

Patent number: 7996125Abstract: A system and method for determining and displaying an overall efficiency value of a vehicle. The vehicle may include an engine and an electric machine that operates to provide torque to propel the vehicle. In addition, the vehicle may have an electric power source that provides electric power to the electric machine. A controller may determine and transmit the overall efficiency value so that the information display displays the number of efficiency indicators. Also, the number of efficiency indicators displayed may be based on the overall efficiency value.Type: GrantFiled: December 22, 2010Date of Patent: August 9, 2011Assignee: Ford Global Technologies, LLCInventors: Ryan J. Skaff, Robert Jay Louch, Anthony Howard, Stephen Burke, David Watson, Angela L. Watson, Derek Hartl, Paul Stephen Bryan

Patent number: 7861655Abstract: A method and apparatus are provided for detonation of a super-compressed insensitive energetic material by cylindrical implosion followed by an axial detonation to a detonation velocity several times that of TNT and a detonation pressure in excess of ten times that of TNT. The device provides a conical metal flyer shell within which is disposed a cylindrical anvil surrounded by explosive. The anvil retains an insensitive energetic material to be compressed and detonated. A first detonation of explosive by impact of the flyer shell generates a reverberating oblique shock wave system for sample compression. Axial detonation of the compressed sample through any length of a sample is achieved following the principal of matching the axial velocity and compression time of the oblique shock wave system to the detonation velocity and induction delay time of the compressed sample. The method and apparatus are also applicable to enhancing the effect of anti-armor and anti-hard-target munitions.Type: GrantFiled: February 25, 2009Date of Patent: January 4, 2011Assignee: National Research Council of CanadaInventors: Fan Zhang, Stephen Burke Murray, Andrew J.
