DEFINITION

Classification: 95/211

Particulate media, fibrous media, or packing elements:

(under subclass 210) Process in which the surface extending mass consists of (a) a plurality of small, discrete solids (e.g., particulate bed, etc.), (b) a mass of slender, elongated material (e.g., a mass of wicklike or threadlike material, etc.), or (c) a mass of randomly oriented or positioned elements which may be molded, machined, or formed, that possess specific advantages of surface availability for gas and liquid contacting (e.g., Raschig rings, Berl saddles, Intalox saddles, Pall rings, etc.).
