DEFINITION

Classification: 239/79

(under the class definition) Apparatus which includes a means to melt particles or bodies of a normally solid substance and contiguous means to distribute the melted substance into the ambient air, usually for the purpose of coating a base surface upon which the distributed material solidifies.

(1) Note. Systems in which a solid or granular material is fused at a point remote from the distributor are not included in this group of subclasses, but are classified in other appropriate subclasses of this class according to the nature of the distributor or system involved.

(2) Note. Included herein are melting distributors which do not disclose any material feeding means or which disclose only material supply pipe or conduit means.
