DEFINITION

Classification: 19/303

(under subclass 296) Method or apparatus wherein (a) fibers are deposited on a fluid permeable condenser by a gaseous stream which has several paths of travel to the condenser; (b) stray fibers caught on the outside of the condenser are returned to one of the air streams for recirculation to the condenser; or (c) unwanted material is removed from the apparatus.

(1) Note. The mere recitation that unwanted materials as dirt, dust, and the like passes through the fluid permeable condenser with the gaseous stream is insufficient to warrant placement herein. The subject matter recited must specify special provision for the separation of handling of the unwanted material.
