Title: Method for capturing mercury from flue gas
Inventor: SRINIVASACHAR SRIVATS
IPC: B01D53/06
Filed: 2009-07-22
Abstract: The present invention relates to use of carbon-based sorbents such as activated carbon for controlling vapor phase mercury emissions in coal-fired power plant flue gases or waste incineration flue gases. The invention features new methods that improve the performance of carbonaceous sorbents for mercury control compared to the previous methods.  One method consists of injecting the sorbent (consisting of at least some carbonaceous material) into the flue gas where the flue gas temperature is at a value above about 1100°F and below about 2000°F.  The invention also consists of injecting the sorbent within or upstream of an economizer section in a coal-fired power boiler. Injecting the sorbent at the locations indicated above, rather than further downstream, provides increased residence time for contact between the flue gas and the sorbent resulting in increased mercury capture, improved sorbent utilization, and improved fly ash properties.

Title: Embedment device for fiber reinforced structural cementitious panel production
Inventor: DUBEY ASHISH
IPC: B32B13/00
Filed: 2008-03-26
Abstract: An embedment device for use in a cementitious panel production line wherein hydraulic cement slurry is transported on a moving web on a support frame, and chopped fibers are deposited upon the slurry. The device includes as one embodiment, a wire grid structure mounted on a reciprocating shaft driven by a piston which moves the grid down into the slurry and then up out of the slurry transverse of the travel of the slurry layer on the web. An alternative embodiment includes a grid cell structure with thin walls extending upward from the grid surface in contact with the slurry moved up and down in a reciprocating motion transverse of the travel of the slurry layer on the web. The intermeshing relationship of the grid cell with the fiber and slurry enhances embedding the fibers into the slurry and prevents device clogging by fibers and prematurely set slurry particles.

Abstract: Provided is a guide wire, which comprises a lengthy wire body, and a marker disposed in at least the tip side portion of the wire body all over the circumference and having a function to indicate the position of the wire body in a living body. The marker is formed into a lattice shape as a whole by causing a first filament portion and a second filament portion to intersect with each other at a plurality of portions. Moreover, the intersecting portions of the first filament portion and the second filament portion are formed in plurality in the marker.  Noting a predetermined one of those intersecting portions, therefore, the predetermined intersecting portion looks, as if it moves radially of the guide wire, when the guide wire is turned on its axis. Thus, it is possible to confirm reliably that the guide wire has been turned.

Title: Method for full-bandwidth deghosting of marine seismic streamer data
Inventor: RIYANTI CHRISTINA D
IPC: G01V1/32
Filed: 2010-10-29
Abstract: Seismic data recorded in a marine streamer are obtained, with the seismic data being representative of characteristics of subsurface earth formations and acquired by deployment of a plurality of seismic receivers overlying an area of the subsurface earth formations to be evaluated, the seismic receivers generating at least one of an electrical and optical signal in response to seismic energy. A complex Laplace frequency parameter is used to transform the seismic data from a space-time domain to a spectral domain. An iterative conjugate gradient scheme, using a physically-based preconditioner, is applied to the transformed seismic data, to provide a least squares solution to a normal set of equations for a deghosting system of equations. The solution is inverse-transformed back to a space-time domain to provide deghosted seismic data, which is useful for imaging the earth's subsurface.

Title: Powdered metal alloy composition for wear and temperature resistance applications and method of producing same
Inventor: CHRISTOPHERSON DENIS B JR
IPC: C22C38/36
Filed: 2009-04-08
Abstract: A powder metal steel alloy composition for high wear and temperature applications is made by water atomizing a molten steel alloy composition containing C in an amount of 3.0 to 3.8 wt%; at least one carbide-forming alloy element which is Cr, V, Mo or W; an O  content less than about 0.5 wt%, and the balance comprising essentially Fe apart from incidental impurities. The high carbon content reduces the solubility of oxygen in the melt and this lowers the oxygen content to a level below that which would otherwise cause the carbide-forming element(s) to oxidize during water atomization. The alloy elements are thus not tied up as oxides and are available to rapidly and readily form carbides in a subsequent sintering stage. The carbon, present in excess, is also available for diffusing into one or more other admixed powders that may be added to the prealloyed powder during sintering to control microstructure and properties of the final part.
