20080271602 | DOPED SUPPORTED ZINC OXIDE SORBENTS FOR REGENERABLE DESULFURIZATION APPLICATIONS - Disclosed are sorbent compositions that include a silicon dioxide porous support impregnated with a mixture comprising zinc oxide and copper material. The sorbent compositions may be utilized in systems and methods for removing sulfur compounds from gaseous streams. | 11-06-2008 |
20080283446 | SILVER-BASED SORBENTS - Disclosed are sorbent compositions that include a porous titanium dioxide support impregnated with a silver material. The sorbent compositions may be utilized in systems and methods for removing sulfur compounds from hydrocarbon streams such as jet fuel. | 11-20-2008 |
20090142234 | Multi-element structured arrays (MESA's) for cost effective and high efficiency treatment of fluids - Multi-Element Structured Arrays (MESAs) present an effective approach to utilizing high pressure drop media that previously were cost prohibitive for use in a traditional filter element. The operational velocity is significantly slowed by the incorporation of numerous elements; thus, eliminating the Darcian flow resistances of the media. The MESAs are readily fitted with two or more replaceable “filter elements” that are able to employ commercially available media, microfibrous entrapped catalyst/sorbent media, unique multilayers and more. A model capable of estimating pressure drop for flow through a pleated filter is able to be used as a design tool to predict minimum initial pressure drop, maximum filtration area, and preferred media properties with respect to permeability versus thickness thus allowing the filtration system's dirt holding capacity, filtration efficiency and operational energy cost and filtration operational and total ownership costs such as blower energy, filter procurement and shipping, maintenance personnel, filter disposal, inventory and storage, cost of money and more to be improved. | 06-04-2009 |
20110135543 | MICROFIBROUS MEDIA AND PACKING METHOD FOR OPTIMIZING AND CONTROLLING HIGHLY EXOTHERMIC AND HIGHLY ENDOTHERMIC REACTIONS/PROCESSES - A vessel packed with a microfibrous media made of micron-sized highly conductive fibers, which are able (and may be used) to immobilize various reactive materials including catalysts, sorbents, electrocatalysts, and other chemically reactive solids. The vessel enables fine temperature control and a uniform temperature profile for a range of highly endothermic or exothermic chemical reactions, sorptions, separation processes, mixing operations, and heat transfer applications. | 06-09-2011 |
20120018351 | Silver-based Sorbents - Disclosed are sorbent compositions that include a porous titanium dioxide support impregnated with a silver material. The sorbent compositions may be utilized in systems and methods for removing sulfur compounds from hydrocarbon streams such as jet fuel. | 01-26-2012 |

20140370607 | DIRECT IN SITU MONITORING OF ADSORBENT AND CATALYST BEDS - Methods and devices for directly measuring the degree of saturation or degree of deactivation of an adsorbent and/or catalytic bed are described herein. The devices contain an inlet, an outlet, a catalytic and/or adsorbent bed, and optionally a support bed for supporting the catalytic and/or adsorbent bed. The devices further contain one or more structures attached to the reactor that allow for insertion of one or more sensors into the reactor. The sensor is used to spectroscopically interrogate the adsorbent and/or catalyst in situ, providing real-time information regarding adsorbant saturation and/or catalyst deactivation. The devices and methods described herein can be used to determine the saturation degree of adsorbent materials or catalyst beds that are involved in gas-liquid and liquid-liquid heterogeneous systems, such as those used in scrubbing and extraction. | 12-18-2014 |

20090109219 | REAL-TIME MESH SIMPLIFICATION USING THE GRAPHICS PROCESSING UNIT - A graphics-processing unit is used to perform mesh simplification. A vertex shader receives a dataset for an input mesh that portrays a three-dimensional graphics object. The vertex shader generates from the dataset vertices for primitives that make up the input mesh. The input mesh is divided into a grid of cells. A geometry shader receives the vertices from the vertex shader and generates from the received vertices a simplified mesh that portrays the three-dimensional graphics object in less detail than the input mesh. Before the input mesh is divided into grid cells, a warping function can be applied to the input mesh based on a weighting function to warp the input mesh, thereby increasing sampling at a region of interest. A projective warping can be performed on the grid to produce grid cells of different volumes in accordance with a camera position. | 04-30-2009 |

20100091018 | Rendering Detailed Animated Three Dimensional Characters with Coarse Mesh Instancing and Determining Tesselation Levels for Varying Character Crowd Density - A method carried out by graphics processing circuitry includes generating animated coarse mesh vertex information based on instanced coarse mesh data; and tessellating instanced coarse mesh data based on the animated coarse mesh vertex information to produce instances of a three dimensional object for display. A graphics processing circuitry includes programmable shader logic operative to execute programmable instructions that when executed cause the programmable shader logic to generate animated coarse mesh vertex information based on instanced coarse mesh data; and tessellate instanced coarse mesh data based on the animated coarse mesh vertex information to produce instances of a three dimensional object for display. Another method carried out by graphics processing circuitry includes determining density of a plurality of three dimensional objects in a current view on a display; setting a tessellation level based on said density; and tessellating said plurality of three dimensional objects. | 04-15-2010 |
