A fuel feed system for use in a gasification system includes a feed preparation section, a pressurization and conveyance section, and a slag additive section. The feed preparation section is configured to grind the fuel to a predetermined size and to adjust the moisture content within the particulate fuel. The pressurization and conveyance section is coupled in flow communication with the feed preparation section, and includes at least one solids pump configured to receive a flow of the particulate fuel at a first pressure and discharge the particulate fuel at a second pressure. The slag additive section is configured to feed a slag additive mixture into the gasifier and to substantially control the total water content within the gasification system.

A method for monitoring functionality of a seal assembly within an injector feed assembly is described. The method includes providing a buffer fluid to the seal assembly, measuring at least one of a pressure and a flow rate of the buffer fluid, and determining a functionality of the seal assembly based at least partially on the at least one of a pressure and a flow rate of the buffer fluid.

A portable target apparatus for use in target practice is provided. The target may be comprised of metal, for example steel. The target includes a base frame and a target plate that is attached to the base frame. Upon being struck by a projectile, the target plate rotates about the base frame into a knocked down position. One or more sensors sense the target is displaced into the knocked down position and a reset mechanism drives the target plate back to the initial position. The base frame of the target apparatus is of hollow construction, thereby making the target portable with relative ease.

A system includes a solid feed pump configured to transport a solid feedstock. The solid feed pump includes at least one passage for the transport of the solid feedstock. The solid feed pump also includes at least one movable wall configured to move along the passage. The solid feed pump further includes a retractable gripping element configured to extend from the at least one movable wall into the at least one passage to grip a portion of the solid feedstock. In addition, the retractable gripping element is configured to retract away from the at least one passage.

A method and system are disclosed for conducting text-based searches of images using a visual signature associated with each image. A measure of string similarity between a query and an annotation associated with each entry in a first database is computed, and based upon the computed string similarity measures, a set of entries from the first database is selected. Each entry of the first database also includes an associated visual signature. At least one entry is then retrieved from a second database based upon a measure of visual similarity between a visual signature of each of the entries in the second database and the visual signatures of the entries in the selected set. Information corresponding to the retrieved entries from the second database is then generated.

A system and method for computing a place profile are disclosed. The method includes providing a geographical definition of a place, retrieving a set of images based on the geographical place definition. With a classifier, image-level statistics for the retrieved images are generated. The classifier has been trained to generate image-level statistics for a finite set of classes, such as different activities. The image-level statistics are aggregated to generate a place profile for the defined place which may be displayed to a user who has provided information for generating the geographical definition or used in an application such as a recommender system or to generate a personal profile for the user.

A blade server 2 is provided with a processor 6 for executing program instructions and an electrical connector 12 for connecting to a blade enclosure 22. The blade server 2 also includes a power controller 18 connected to a plurality of power supply batteries 14, 16 which are provided on the blade server 2 itself. If the power controller 18 detects that the main power supply supplied via the electrical connector 12 has been interrupted, then a backup power supply to the processor is provided from the on-board power supply batteries 14, 16. The batteries 14, 16 on each blade are periodically discharged and recharged in turn to check their proper function.

A method of assembling a synthesis gas (syngas) cooler for a gasification system includes positioning a dip tube within a shell of the syngas cooler. The dip tube is configured to quench the syngas flowing through the shell and/or at least partially channel the syngas through the dip tube. The method also includes coupling an isolation tube to the dip tube such that the isolation tube is substantially concentrically aligned with, and radially outward of, the dip tube. The isolation tube is coupled in flow communication with a purge gas source and is configured to at least partially form a dynamic pressure seal. The method further includes coupling at least one of the isolation tube and the dip tube in fluid communication with a fluid retention chamber. The method also include at least partially filling the fluid retention chamber with fluid, thereby further forming the dynamic pressure seal.

A method of startup for a gasification system includes assembling a fuel mixture for use by a gasifier at a fuel mixture assembly point, wherein the fuel mixture includes a quantity of particulate solid fuel and a quantity of non-ventable carrier gas. The method includes channeling the fuel mixture through a first conduit to a fuel mixture disassembly system including a non-ventable carrier gas removal apparatus, establishing a substantially steady flow of the fuel mixture within the first conduit, and redirecting the fuel mixture through a second conduit to the gasifier to facilitate gasifier startup.

A scroll compressor having a scroll wall arrangement with a fixed scroll having fixed scroll walls and an orbiting scroll having orbiting scroll wall, an inlet at a radially outer portion and an outlet at a radially central portion, a first flow path defined by the orbiting and fixed scroll walls and extending from the inlet to the outlet, gas entering through inlet at a pressure and exhausting through outlet at a second pressure higher than the first pressure. Scroll wall arrangement having a second inlet through which gas enters at a third pressure and follows a second fluid path where it is exhausted through the outlet at the second pressure to form two flow paths having respective inlets. The third pressure at which gas enters through inlet is different from the first pressure, and lower than the second pressure.
