International Classification:

B01D 29/07
B01D 29/31

US Classification:

2104934, 210450, 2104931, 2104932, 2104935, 21049701, 2104971

Abstract:

A filter has a longitudinal axis with an inner diameter defined by a hollow longitudinally extending center. The filter has fingers extend radially outwardly arcuately from the longitudinal axis. The fingers have base ends near the longitudinal axis and outer edges at extremities spaced from the longitudinal axis. The outer diameter of the filter is defined by the outer edges of the fingers. The filter is formed from a sintered porous molded thermoplastic or another material resulting in a filter more rigid than standard filters. The fingers are spaced apart from one another a predetermined, substantially fixed distance to form slots therebetween sized to capture contaminants therein.

US Classification:

427230, 427244, 4274211

Abstract:

Methods of making porous composite materials are provided. These methods involve providing a sintered porous first polymeric material, providing a solution containing a second polymeric material dissolved in a solvent, and, depositing the solution onto the sintered porous first polymeric material to form a precipitated porous second polymeric material wherein a portion of the second polymeric material is fused to the sintered, porous first polymeric material by at least one direct physical bond, and the second polymeric material is in at least some of the pores of the first polymeric material. In some methods, the first polymeric material and the second polymeric material are soluble in the same solvent.

US Classification:

422/186070, 210/198100, 210/760000

Abstract:

A liquid barrier is disclosed that comprises a porous hydrophobic material which allows the flow of gases (e.g., corrosive gases) but inhibits the flow of liquids, including aqueous liquids. A specific embodiment of the invention relates to a venturi which incorporates a liquid barrier that allows the flow of gases (e.g., ozone and air) but inhibits the flow of liquids. Another specific embodiment of the invention relates to an ozone generation system that includes an ozone generator and a liquid barrier made of a porous hydrophobic material, which allows the flow of ozone but inhibits the flow back of liquids to the ozone generator. The invention also encompasses methods of introducing a gas into an aqueous liquid, wherein the gas passes through a liquid barrier prior to being introduced into the aqueous liquid.
