DEFINITION

Classification: 239/290

(under the class definition) Apparatus having in addition to the spray material outlet, outlet means for enshrouding or causing the spray to be confined beyond the egress means to or within a particular configuration or outline by a nonliquid fluid medium.

(1) Note. The gas for atomization if any must be provided by means other than the shaping or shielding streams although it may be that further atomization results from the impingement of the auxiliary stream upon the main stream.
