20080022852 - Zinc-oxide-based sorbents and processes for preparing and using same: The disclosure relates to zinc oxide-based sorbents, and processes for preparing and using them. The sorbents are preferably used to remove one or more reduced sulfur species from gas streams. The sorbents comprise an active zinc component, optionally in combination with one or more promoter components and/or one or more... Agent: Alston & Bird LLP

20080022853 - Aerodynamic lens particle separator: Respirable particles with diameters on the order of 0.05 to 10 microns entrained in an air stream. are concentrated in an aerodynamic lens (FIG. 2) for separation from the air steam. The entire structure is made by microfabrication techniques, such as silicon micro-machining which enables arrays of precisely aligned slit... Agent: J. Michael Neary Neary Law Office

20080022854 - Method of drying an object and apparatus for performing the same: In a method of drying an object, a first drying fluid and a second dry fluid may be first heated to form a gas mixture. The gas mixture may be second heated to prevent the mixed gas from condensing. The second heated gas mixture may be filtered to remove impurities... Agent: Harness, Dickey & Pierce, P.L.C

20080017028 - Purification of polluted air: A process for purifying polluted air includes passing the polluted air through a fluidized bed of micro-organism-containing particulate media. As the polluted air passes through the fluidized bed, organic pollutants therein are decomposed by the micro-organisms. Purified air containing a lower level of the organic pollutants than the polluted air... Agent: Ratnerprestia

20080017029 - Asymmetric hollow-fiber gas separation membrane, gas separation method and gas separation membrane module: The present invention relates to an asymmetric hollow-fiber gas separation membrane made of a polyimide having a specific repeating unit, an improved tensile elongation at break of 15% or more as a hollow-fiber membrane itself, an oxygen gas permeation rate (P′O2) of 4.0×10−5 cm3 (STP)/cm2·sec·cmHg or more and a gas... Agent: Young & Thompson

20080017030 - Method and filter arrangement for separating exhaust particulates: A method and apparatus for the operation of a filter arrangement for separating exhaust particulates from an exhaust gas stream, in which the exhaust gas stream is guided through ducts (20) of a ceramic body (1), which ducts extend in the longitudinal direction of a ceramic body (1) and are... Agent: William Collard Collard & Roe, P.C.

20080017031 - Gas filtration system and filter cleaning method: An apparatus (10, 200, 250, 250′) for filtering particulates from a gas, comprising a casing (22, 24, 202) defining an inner cavity having an inlet (30, 210, 260) adapted to receive a flow of gas, such that gas enters the inner cavity, and an outlet (40, 231, 281) through which... Agent: Ogilvy Renault LLP

20080017032 - Method and means for simultaneously generating an aqueous froth and numerous micro-droplets for use in filtering a contaminated air stream: A method and apparatus are provided for improving the efficiency of an aqueous froth filter. An array of saturated mesh assemblies interacts with an incoming contaminated air stream. As the air stream flows through the saturated mesh assemblies, an aqueous froth is generated immediately downstream of each mesh assembly. As... Agent: Bruce H. Johnsonbaugh Eckhoff & Hoppe

20080017034 - Process for producing a ceramic filter: The invention concerns a process for producing a ceramic honeycomb filter from a porous ceramic honeycomb material comprising a plurality of channels extending through it from one end face to the other end face. The process of the invention comprises at least the following steps consisting of a) providing each... Agent: Millen, White, Zelano & Branigan, P.C.

20080006150 - System with canopy and electrode for air cleaning: System for separating particles from an environment, the system comprising a perforated screen and an ionisation electrode in the environment for creating an electrostatic potential between the electrode and the screen to attract the particles to the screen....
