Abstract: An encapsulated filter cartridge is disclosed, which includes a filter assembly including a carbon block filter element and a microporous filter element. The filter cartridge has a permanently sealed sump defining an interior chamber configured to accommodate the filter assembly, the sump having an inlet for permitting unfiltered fluid to enter the interior chamber for communicating with the radially outer surface of the filter assembly and an outlet for permitting filtered fluid to exit the interior chamber from the axial portion of the filter assembly. The microporous filter element of the filter assembly may include a hollow fiber subassembly housed within the axial cavity of the carbon block element, said fiber subassembly including a plurality of hollow microporous fibers, or a pleated filter element surrounding the radially outer surface of the carbon block element.

Abstract: A filter and filter material for providing or treating potable water is provided. The filter includes a housing having an inlet and an outlet, a filter material disposed within the housing, the filter material formed at least in part from a mixture of a plurality of mesoporous and microporous activated carbon particles. Preferably, at least some of the mesoporous activated carbon filter particles are coated with a cationic polymer, and even more preferably, at least some of the particles are coated with a cationic polymer and silver or a silver containing material. Kits comprising filters and information relating to the reduction, killing or removal of bacteria, viruses, microbials, and TTHM are also provided.

Abstract: An exhaust hood for a turbine includes a shell casing, an external support structure, conical corner plates, and a butterfly plate. The shell casing includes an inner surface and an outer surface. The external support structure is coupled to the shell casing outer surface, and provides structural support to said shell casing. The butterfly plate is coupled to the shell casing inner surface for channeling flow into the exhaust hood and subsequently into the condenser. The butterfly plate has a substantially elliptically-shaped cross-sectional profile that facilitates reducing flow separation losses of steam flowing therethrough into the exhaust hood.

Abstract: An improved fluid filtration media having anti-microbial properties and methods for producing and utilizing improved fluid filtration media having anti-microbial properties and employing the same in fluid filtration applications wherein one representative separation media for fluids comprises a base mixture of organic and inorganic components comprising at least one anti-microbial component; and at least one component of the base mixture comprises a charge-modified group covalently bonded to the surface of the at least one anti-microbial component is disclosed.

Abstract: An improved liquid filter device comprising a first non-collapsible filter element formed of filter media; a second non-collapsible filter element formed of filter media, the first filter element being operatively contained within the second filter element such that a first space is operatively formed therebetween, the first filter element operatively forming a second space interiorly thereof; an inlet plate, operatively connected at one end of both the first and second filter elements, the inlet plate having an outer circumferential edge and a central area, the second filter element being operatively connected to the inlet plate proximate to the outer edge of the inlet plate, the first filter element being connected to the inlet plate proximate to the central area, the inlet plate operatively communicating with the first space between the first and second filter elements such that the flow of liquid to be filtered is directed into the first space, each filter element being non-collapsible in the axial direct

Abstract: A filter assembly for a filter cartridge is disclosed, the filter assembly including a generally cylindrical carbon block filter element and a generally cylindrical pleated filter element disposed around the radially outer surface of the carbon block filter element. The filter assembly has an outlet communicating with the axial cavity of the carbon block filter element, so that filtrate first passes through the pleated filter element, enters the carbon block filter element through its radially outer surface, propagates radially inwardly to the central cavity of the carbon block filter element and then axially along the central cavity of the carbon block filter element, and exits the central cavity of the carbon block filter element through the outlet.

Abstract: An inner shell of a steam turbine has discrete arcuate steam outlet ports through an axial face. In axial opposition is a nozzle ring including a pair of nozzle ring segments joined at a horizontal midline. At the midline joint, split partitions are employed to provide a full 360° discharge through the nozzle ring. The split partitions are split in an axial direction to define discrete partition portions in each of the nozzle ring segments adjacent the midline joint.

Abstract: A turbine shell assembly includes radially inner and outer shell components; axial alignment fits on the inner and outer shell components, each alignment fit comprising a male fit component on one of the inner and outer shell components and a female fit component on the other of the inner and outer shell components, the female fit component comprising a pair of flanges forming a U-shaped channel with opposed faces, and the male fit component comprising a projection received within the U-shaped channel; and a pair of axial alignment keys, each key having a mounting flange for securement along an outer edge of a respective one of the pair of flanges and an alignment flange engaged along a respective one of the opposed faces.

Abstract: A filter element (10) comprises a porous, thick-walled, integral, self-supporting, resin impregnated and bonded fibrous, tubular filter structure (11) having a hollow core (15); an inner shell (20) of a first large pore size porous media adjacent the hollow core and forming the majority of the filter structure; and an outer shell (21) of a second small pore size porous media, finer than the first porous media and adjacent the inner shell, the first and second porous media being resin impregnated and bonded.
