(under subclass 133) Methods and means in which gaseous currents flowing in an inclined direction--that is, having both vertical and horizontal components of motion--are employed to freely suspend components of material.
(1) Note. There is usually both elevation and horizontal displacement of the suspended material; but cases involving the use of currents flowing in a downwardly inclined direction maybe included.
(2) Note. Many instances are included in which the material not freely suspended flows down an inclined wall or support, resembling to some extent those stratifiers which employ an inclined gaseous current for removal of the lighter. The distinction between the two generally is that in the suspension subclasses employing the inclined current the inclination of the wall is such that the material on the wall or support will normally flow freely or rapidly down the support and not be detained to form a definite stratum.
