Abstract
A converter for treating gases to remove pollutants or particulate matter having layers of normally nesting corrugated thin metal foil, with or without a catalyst supported thereon, and characterized by spaced strands of wire or nonvitreous inorganic ceramic thread interposed between the layers to maintain them in spaced relation for the passage of gas, e.g., exhaust gas from an engine or plant, therethrough. The principal advantages are the relatively high particulate trap efficiency, the relatively low back pressure, and the low cost of manufacture.
