Abstract: A turbine unit (11) adapted to be placed in a flowing fluid. The turbine unit (11) comprises a first turbine set (13) and a second turbine set (15) mounted within a passage (21) of a housing (19). The first turbine blade set (13) and a second turbine blade set (15) are set in opposed relation such that in operation a region between the two turbine blade sets (13, 15) has a lower pressure than the fluid pressure at an opening of the passage (21). The turbine unit (11) being used to generate power. The turbine units (FIGS. 8 to 11) can be abutted with each other such that they define a passage and each turbine unit comprises a driving turbine blade set before fluid passes to a pumping turbine blade set.

Abstract: An apparatus for removing particulate matter from a gas stream containing particulate matter, the apparatus including: a mist-producing element that mixes a gas stream entering the apparatus with liquid droplets; and a down flow Wet Electrostatic Precipitator (WESP) pass section having ionizing electrodes that electrically charge the particulate matter and the intermixed liquid droplets, and collecting surfaces in the form of an array of polygonal tubes, wherein the collecting surfaces are under the influence of an electrical field to attract and remove electrically-charged particulate matter and intermixed liquid droplets from the gas stream. An embodiment utilizing two down-flow Wet Electrostatic Precipitator (WESP) sections (i.e.

Abstract: Complex, three-dimensional, variable section casts with a high level of dimensional control can be made from molds consisting of two flat or tailored sheets of flexible material (such as fabric) held between rigid clamps. The clamping materials control the shape and dimension of the mold in the X and Y directions while the flexible sheets are allowed to deflect in the Z direction. Void shapes in the truss can be obtained when the clamping material presses the two sheets together.

Abstract: An apparatus for removing particulate matter from a biomass combustion gas stream, the apparatus having a mist-producing element that mixes a gas stream entering the apparatus with liquid droplets; a Wet Electrostatic Precipitator (WESP) section that includes ionizing electrodes that electrically charge the particulate matter and the intermixed liquid droplets and collecting surfaces under the influence of an electrical field which attract and remove electrically-charged particulate matter and intermixed liquid droplets from the gas stream; and a scrubbing section that provides for additional scrubbing of the gas.

Abstract: A method and apparatus for the oxidation of NO, SO2, and mercury vapors and their subsequent removal from a waste gas together with solid submicron particles and acid droplets comprising the reagent injection, WESP/plasma reactor, liquid film catalytic reactor and FGD scrubber with WESP/mist eliminator for the final gas cleaning.

Abstract: An apparatus and method for removing particulate matter and undesirable vapors from a gas stream are provided. In one aspect, an apparatus includes at least one ionizing electrode that negatively charges the particulate matter and condensed droplets of undesirable vapors, at least one scrubbing element including a collecting surface, and at least one liquid applicator operable to apply a liquid film to the collecting surface, wherein a positive charge is applied to the liquid film to attract negatively-charged particulate matter and/or condensed droplets of undesirable vapors to the collecting surface. In another aspect, a method includes the steps of: negatively charging the particulate matter and condensed droplets of undesirable vapors using at least one ionizing electrode; applying a liquid film to a collecting surface proximate the ionizing electrode; and positively charging the liquid film to attract the negatively-charged particulate matter and condensed droplets of undesirable vapors.

Abstract: There is described a method of processing data packets in a data stream in a communication system. In the method, a plurality of data packets from the data stream are analysed in order to generate profile data which indicates how one or more parts of each of the plurality of data packets varies from data packet to data packet. The profile data is then made available so that a data packet compression scheme that accords with the profile data can be implemented on data packets in the communication system.
