Abstract
Abstract Gas contacting packing, such as for moisture, heat exchange, catalytic contact and the like, said packing for gas using a metallic foraminous framework for heat or moisture exchange particles while allowing free flow of air thereabout for heat or moisture exchange particles while allowing free flow of air thereabout for optimum surface contact while providing a stable structure, the metallic support having woven wire framework disposed in layers or sheets which may be corrugated and of perforated metal, whereby air may pass both radially and axially in free-flowing contact with the particles.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
136 words
Fluid contacting packing comprising a foraminous metal body comprising an open metal framework having multiple supporting layers disposed three-dimensionally in said framework forming a porous lattice of vertically and horizontally laminated layers allowing easy fluid flow therethrough in all directions, said framework having an adhesive coating over substantially the entire metallic surface exposed body thereof, fine solid particles separately distributed upon and bonded only by the exposed surface of said adhesive, said particles being granularly shaped to provide fluid permeability through interstices therebetween in bonded position upon said metal framework, said particles being selected to affect the physical or chemical substance of the fluid such as its moisture, heat exchangive or catalytic activated condition, whereby such particles are firmly and separately supported in the framework space for optimum surface contact with fluid passed in contact therewith.
