Raw and uncomminuted refuse is introduced through an entrance port into a substantially closed chamber as a horizontally flowing stream so that the refuse drops in the chamber along a path. A current of air is circulated in a closed circuit through the chamber and is directed in the chamber generally perpendicular to the path of the falling refuse and is inspired in the chamber through a sieve oriented substantially perpendicular to the current in the chamber. A minor portion of the air is withdrawn from the circuit, filtered, and released to the atmosphere. This withdrawn portion is replaced in the circuit by drawing air into the chamber substantially only through the entrance port so that slight subatmosphere pressure is created in the chamber to prevent the generation of unwanted dust or smell.

Method of and apparatus for classifying refuse

A method for producing a multifilament yarn by melt spinning of individual filaments which are grouped together to form yarn, in which, before winding, the yarn is subjected, in addition to the actual removal forces acting from the outside on the yarn, to further forces produced by gas streams which accompany the yarn in its longitudinal direction.
