DEFINITION

Classification: 239/128

(under the class definition) Apparatus in which either the material to be sprayed or the apparatus parts are subjected to a treatment which either raises or lowers the temperature thereof.

(1) Note. A device in which an incandescent or radiant member or a system part as claimed, is positioned in the path of the fluid discharged or distributed from the system, which fluid is disclosed as ignitible to produce a flame, thus heating the member, the system part or the system fluid, whether or not the flame is actually claimed, is excluded from Class 239 and will be found in Class 431, Combustion.

(2) Note. Mere heat insulating means is excluded under this definition and will be found in subclass 397.5.

SEE OR SEARCH THIS CLASS, SUBCLASS:

13, for corresponding processes.

79+, for apparatus involving the fusion of solid or granular material in the nozzle prior to or during spraying.

125, for burner nozzle cooling by recirculation of spray fluid within the nozzle.
