| 20090041084 | TEMPERATURE MEASUREMENT DEVICE THAT ESTIMATES AND COMPENSATES FOR INCIDENT RADIATION - A temperature measurement device includes a first thermocouple mounted on a tubular body that is shielded from the effects of radiation by a radiation shield, and a second, unshielded thermocouple. A difference in the measured temperatures from the first and second thermocouples is compared with calculated temperatures using an iterative process to determine a corrected temperature of the gas stream that estimates and compensates for incident radiation. | 02-12-2009 |
| 20090041642 | Radiant coolers and methods for assembling same - A method of assembling a radiant cooler is provided. The method includes providing a vessel shell that includes a gas flow passage defined therein that extends generally axially through the vessel shell, coupling a plurality of cooling tubes and a plurality of downcomers together to form a tube cage wherein at least one of the plurality of cooling tubes is positioned circumferentially between a pair of circumferentially-adjacent spaced-apart downcomers, and orienting the tube cage within the vessel shell such that the tube cage is in flow communication with the flow passage. | 02-12-2009 |
| 20090074347 | FIBER BRAGG GRATING FOR HIGH TEMPERATURE SENSING - A method of fiber core material band gap engineering for artificially modifying fiber material properties is provided. The method includes doping the fiber core material with one or more atoms for enhancing photosensitivity to the fiber material. The method also includes co-doping the fiber core material with one or more ions for enhancing an amorphous network crosslink mean coordination number. The method further includes thermally annealing the fiber core material for widening the band gap of the fiber core material. | 03-19-2009 |
| 20090130001 | METHODS FOR FABRICATING SYNGAS COOLER PLATENS AND SYNGAS COOLER PLATENS - A method for fabricating a syngas cooler is provided. The method includes coupling a tube cage within the syngas cooler, and coupling a plurality of platens to the tube cage to facilitate steam production in the syngas cooler. At least a first platen has at least one of a length that is larger than a length of a second platen, a non-linear geometry, and an angular position that is oblique with respect to a wall of the syngas cooler. | 05-21-2009 |
| 20090199474 | APPARATUS FOR COOLING AND SCRUBBING A FLOW OF SYNGAS AND METHOD OF ASSEMBLING - A method of assembling a spray quench apparatus is provided. The method includes coupling a first end of an exit tube to a quench chamber such that the exit tube end is in flow communication with the quench chamber, coupling at least one spray nozzle to an opposite second end of the exit tube such that water emitted from the spray nozzle fills the exit tube and forms a film of water across an inner surface of the exit tube, coupling a water source to the quench chamber for providing a substantially continuous water film along an inner surface of the quench chamber, and coupling at least one discharge apparatus to the quench chamber for providing water spray into the quench chamber, wherein the water of the water film and water sprays drains into a water sump. | 08-13-2009 |
| 20090262777 | HEAT FLUX MEASUREMENT DEVICE FOR ESTIMATING FOULING THICKNESS - A heat flux measurement device includes at least two thermocouples disposed within a front portion of the device at different axial distances from a front wall of the device. A correlation between the measured heat fluxes from the device over a period of time is used to estimate a fouling thickness on a wall, for example, a water wall of a radiant syngas cooler (RSC). | 10-22-2009 |
| 20100113210 | Split torque compound planetary drivetrain for wind turbine applications - A compound planetary gear transmission unit includes a second stage with axially staggered planets. | 05-06-2010 |
| 20110185568 | METHODS AND APPARATUS FOR REPLACING OBJECTS ON HORIZONTAL SHAFTS IN ELEVATED LOCATIONS - An apparatus for stabilizing a shaft in an essentially horizontal position while an anchoring object at one end of the shaft is replaced without removal of an object at the opposite end of the shaft that would otherwise tend to destabilize the shaft from its essentially horizontal position includes a half-spool member configured to clamp above and around the shaft to resist torque around the rotor, under supports configured to attach to the half-spool member and clamp an underside of the shaft below the half-spool member, and a hydraulic or mechanical brake configured to resist torque on the shaft when the brake is engaged. | 08-04-2011 |
