Abstract: Combustion systems having reduced nitrogen oxide emissions and methods of using the same are disclosed herein. In one embodiment, a combustion system is provided. The combustion system includes a combustion zone, which includes a burner for converting a fuel, under fuel rich conditions, to a flue gas. An intermediate staged air inlet is downstream from the combustion zone, for supplying intermediate staged air to the flue gas and producing fuel lean conditions. A reburn zone is downstream from the intermediate staged air inlet for receiving the flue gas. A process for using the combustion system and a method of reducing NOX flowing into the reburn zone of a combustion system are also described herein.

Abstract: A combustion system for combusting air and fuel includes a primary combustion zone configured to produce combustion gases from the air and the fuel and an intermediate air zone downstream from the primary combustion zone. The intermediate air zone is configured to inject an intermediate air stream into the combustion gases. The combustion system further includes a burnout zone downstream from the intermediate air zone, wherein the burnout zone is configured to inject an overfire air stream into the combustion gases, and at least one hybrid-boosted air injector within at least one of the intermediate air zone and the burnout zone. The at least one hybrid-boosted air injector is configured to substantially simultaneously inject a boosted air stream and a windbox air stream into the combustion gases.

Abstract: The disclosure and claims herein are directed to efficient journaling for recovery of a database index by journaling zones of a page. A journal mechanism maintains a page zone bit map that includes a bit for a plurality of zones in each page to indicate which zones have had their unchanged image journaled before being changed since a last sync point update. The page zone bit map has a bit for each zone in each page so that the status of each zone can be tracked separately. Tracking the smaller zones of the pages makes the process more efficient both at run time and during recovery by reducing the period of time for memory deposits and reducing the amount of total redundant/recovery data sent to disk for larger pages.

Abstract: A digging system includes a machine having a machine frame, and an implement assembly mounted to the machine frame. The implement assembly includes an elongate boom and a trenching mechanism having a plurality of drawing cutters coupled with an endless drive chain movable about a drive system mounted to an elongate boom. The implement assembly further includes an undercutting mechanism having first and second rotating cutters projecting in opposite axial directions from the distal boom end. The implement assembly defines a compound projection profile in a plane which includes first and second axes of rotation of a drive wheel and guide wheel of the drive system. The compound projection profile includes a relatively narrow proximal stem segment corresponding to the trenching mechanism and a relatively broad distal footing segment corresponding to the undercutting mechanism.

Abstract: A method and system for controlling a temperature of an exhaust gas being introduced to a catalyst is provided. Using an adjustable flow controller, an adjustable amount of tempering fluid is provided to the exhaust gas prior to the exhaust gas proceeding to the catalyst. A sensor senses a parameter indicative of a temperature of the exhaust gas being introduced to the catalyst. A computer processor uses a relationship to relate the parameter to an adjustment of the adjustable flow controller that will adjust the amount of tempering fluid provided to the exhaust gas and change the temperature of the exhaust gas being introduced to the catalyst toward a target temperature. Adjustment of the adjustable flow controller is initiated by the computer processor to change the flow of the tempering fluid, and the relationship between the parameter and the adjustment of the adjustable flow controller is updated.

Abstract: A three wheel electric vehicle platform with two wheels in front and one wheel at the rear, a full safety roll cage, a propulsion and steering system operating through the two front wheels, and operator's and passenger's seats mounted in-line along the vehicle centerline. The propulsion system is an electric motor powered by an energy storage device driving a speed reduction and differential with dual outputs suitable for two wheel front drive. The operator's seat is narrower in parts than a conventional automotive seat such that the rear seat passenger's knees can comfortably straddle the operator seat to allow the distance between the two occupants to be less than a typical automobile. The driver's and passenger's heels comfortably fit into recessed wells within the energy storage device, thus allowing the driver's and passenger's center of gravity to be lower, while still maintaining a comfortable sitting position.

Abstract: A minimized journaling mechanism stores minimized journal data in a format that allows for display and outputting the journal data in human-readable form. When a change to a record occurs, instead of writing only the changed bytes, all of the bytes in each field that changed are written to the journal, along with all of the bytes in each field selected to be always journaled. A default object is created with default data in all of the fields. When the journal entry needs to be output in human-readable form, the default object is read, and the minimized journal entry is then overlaid on the default object. The result is an object that contains default data in all non-selected fields that were not changed, with the journal data in all fields and that did change and in all fields that were selected to always be journaled.
