Short contact time catalytic partial oxidation process for recovering sulfur from an H2S containing gas stream
InactiveUS6946111B2Avoid contactExcess buildupHydrogenDispersed particle separationPartial oxidationSulfur
A process for removing sulfur from a H2S-containing gas stream is disclosed. A preferred embodiment of the process comprises incorporating a short contact time catalytic partial oxidation reactor, a cooling zone, and a condenser into a conventional refinery or gas plant process, such as a natural gas desulfurizer, a hydrotreater, coker or fluid catalytic cracker, in which sulfur removal is needed in order to produce a more desirable product. An H2S-containing gas stream is fed into a short contact time reactor where the H2S is partially oxidized over a suitable catalyst in the presence of O2 to elemental sulfur and water.

Bamboo splitter
A bamboo splitter has an outer support ring with an interior mounted inner ring blade. A plurality of base blades are radially arranged around the inner ring blade and both the inner ring blade and the base blades have v-shaped cutting surfaces. Attached to each base blade is a pair of slat blades that attach to the base blades at a vertex and have a left and right slat blade. The angle between the vertex and the left and right blades is chosen so that adjacent left slat blades are parallel to adjacent right slat blade forming a parallel cutting space which produces bamboo slats that have orthogonal edges which makes them much more amenable to traditional building methods. A different number of slat blades may be used depending on the size of the bamboo being used and the size and number of the slats being produced.

A bag house filtration system in which the filter media includes a woven textile formed from glass yarns other high temperature resistant yarns. A first bath is applied to the textile which contains a conductive component, a first fluoropolymer and a lubricant (in some cases where the yarns are glass). A second bath containing primarily a second fluoropolymer is then applied to the textile and the first composition to seal the first composition on the textile. The textile, so treated dissipates the static electricity normally generated in the filter media thus reducing excessive buildup of contaminating particles and enhancing cleaning of the bag during use.

Optically rebalanced accelerometer
InactiveUS6867411B2Reduce weightExcess buildupPhotometry using reference valueAcceleration measurement using interia forcesOptical radiationLocation detection
An optical accelerometer for detecting an acceleration of a proof mass includes a source of optical radiation for generating a pair of beams of output radiation. The pair of beams of optical radiation exerts radiation pressure on the proof mass, so as to maintain the proof mass in an equilibrium position along a sensing axis. A position detecting system detects a displacement from the equilibrium position of the proof mass along the sensing axis in response to an inertial force acting on the proof mass. A modulator adjusts the intensity of each one of the pair of beams, so as to restore the proof mass to the equilibrium position along the sensing axis. The difference in the adjusted intensities of each one of the pair of beams is representative of the acceleration, resulting from the inertial force, of the proof mass along the sensing axis.

Porous sintered anode bodies for capacitors formed from valve metals are treated by electrolysis to form a dielectric layer and coated with cathode layers. When standard parallelpiped shapes are used, cathode coverage at the edges and corners is non-uniform and failures occur at those locations. Rectangular prisms, obround prisms and cylindrical prisms are formed with transition surfaces at edges and corners, such as chamfers and curves, to enhance cathode layer uniformity. The transition surface greatly enhances the application of polymer slurries.

Each time a version of a virus pattern is downloaded to a local computer a scanned file cache is generated including all files scanned by that version. A modified file cache is also generated including all files modified while that version is present. After a minimum time interval or after a minimum number of virus pattern versions, a white list is generated by combining the existing white list, versions of the scanned file cache and the modified file cache. The white list (and the other caches) is represented by a single binary digit per file that is indexed by the i-node number of the file's i-node. A bundle of files (or their unique identifiers) on the white list is created and uploaded to a cloud storage service. A local computer sends a request to the storage service for the white list for a particular bundle which is then downloaded to the local computer.
