Patent number: 8940168
Abstract: The present disclosure describes an axial bypass sleeve for use with a spiral wound membrane element. The axial bypass sleeve has a protrusion and an opening that defines a flow path to provide fluid flow communication through the axial bypass sleeve. In use, the axial bypass sleeve is wrapped around a spiral wound membrane element and both are placed in a pressure housing. A pressurized feedstock is introduced into the pressure housing. A portion of the pressurized feedstock flows through the spiral wound membrane element to produce a permeate stream and a retentate stream. A portion of the pressurized feed stock flows around the spiral wound membrane element, called bypass flow. The protrusion extends into the annular space to restrict the bypass flow. A portion of the bypass flow passes through the opening and enters into the spiral wound membrane element to increase permeate production.

Patent number: 8939715
Abstract: A turbine bucket tip clearance control system includes a rotor assembly having a rotor supporting a plurality of axially spaced wheels, each wheel mounting an annular row of buckets, the annular row of buckets on at least one of the plurality of axially-spaced wheels having a radially outer tip shroud provided with at least one seal tooth. A stator assembly includes a radially inwardly facing, axially-stepped surface, formed with radially inner and outer seal surfaces connected by a shoulder. The stator assembly and rotor assembly are moveable axially relative to each other, enabling selective positioning of the at least one seal tooth radially opposite one of the radially inner and outer seal surfaces to thereby selectively alter a clearance gap between the at least one seal tooth and the radially inward facing axially-stepped surface.

Patent number: 8939294
Abstract: A separation matrix comprises a porous surface layer; and a bulk porous support, wherein both the porous surface layer and the bulk porous support comprising a block copolymer. The block copolymer comprises A-B or A-B-A repeating units, wherein A and B at each occurrence are two different blocks of oligomer, or polymer. A structural unit of block A is derived from one or more atom transfer radical polymerization (ATRP)-active monomer or oligomer and a structural unit of block B is derived from a thermoplastic ATRP-active macro initiator. A poly dispersity index of the block copolymer is at least about 2.

Patent number: 8940169
Abstract: A spiral wound module is suitable for use with high temperature water that is also very alkaline or has a high pH, for example SAGD produced water. The module uses a polyamide-based membrane with a polysulfone or polyethersulfone backing material. For other components, the module uses primarily one or more of, EPDM; polyamide; polyphenylene oxide; polyphenylene sulfide; polysulfone; polyethersulfone; polysulfonamide; polyvinylidene fluoride; mylar; fiberglass; and, epoxy. Polyester is not used. Polypropylene is not used for the feed spacer. For example, a module may use a PVDF feed spacer, a nylon permeate spacer and a polysulfone center tube. The center tube may be provided with 4 rows of 0.063? diameter holes and be rolled under high tension.

Patent number: 8942108
Abstract: A differential protection system is provided. The differential protection system includes a local terminal configured to be communicatively coupled directly or indirectly with at least two remote terminals via at least three communication links to form a ring topology or a mesh topology. The differential protection system further includes a controller comprising a communication link decision unit and a clock unit associated with the local terminal. The communication link decision unit is configured to determine some of the at least three communication links as virtually disconnected such that the ring topology or the mesh topology is configured to be converted to a daisy chain topology. The clock unit is configured to time synchronize the local terminal with at least one of the at least two remote terminals when the local terminal and the at least two remote terminals are configured in the daisy chain topology.

Patent number: 8942341
Abstract: A CT system includes an x-ray source configured to project an x-ray beam toward an object, a detector array, and a bowtie filter. The bowtie filter includes a first x-ray filtration region positioned to attenuate x-rays that pass through an isochannel of the detector array, a second x-ray filtration region positioned to attenuate x-rays that pass through channels of the detector array that are offcenter in a channel direction from the isochannel, and an x-ray attenuation material positionable to attenuate the x-rays that pass through the channels of the detector array that are offcenter in the channel direction from the isochannel. The CT system also includes a data acquisition system (DAS) connected to the detector array and configured to receive outputs from the detector array, and a computer programmed to acquire projections of imaging data of the object, and generate an image of the object using the imaging data.
