DEFINITION

Classification: 118/58

(under the class definition) Coating apparatus combined with means to heat, cool, dry and/or contact a noncoating gas or vapor with the work, before, during and/or after the coating operation.

(1) Note. Devices for merely holding the base in the ambient air for the purpose of cooling the same are excluded from this subclass. For such subject matter search the appropriate work handling subclasses set forth below.

(2) Note. Means for merely applying heated coating material to the base or mere heating systems for the coating material are not considered subject matter for this subclass. Separate means must be provided to apply heat directed to the base to be classified here. Mere heated receptacles for coating material, or systems for conveying heated coated material, or systems for heating the coating while on the base must be searched in the various classes noted below, which classes provide for such apparatus.

SEE OR SEARCH THIS CLASS, SUBCLASS:

20, for similar apparatus for treating edible work.

47, for coating apparatus in which a flame directly contacts the work piece or having means to cause ignition of the coating material on the base. 620, for coating apparatus having means to apply electrical energy directly to the work to generate heat.

641+, for coating apparatus having means to apply radiant energy directly to the work to generate heat.

715+, for coating apparatus having means to contact the base with a gaseous or vaporized coating material.

SEE OR SEARCH CLASS

34, Drying and Gas or Vapor Contact With Solids, appropriate subclasses and see the notes of the class definition of that class for drying means, per se. Class 118 provides for the combination of coating and drying. Means to treat a coating with a solvent vapor to smooth, polish or coalesce the coating, per se, is in Class 34.

264, Plastic and Nonmetallic Article Shaping or Treating: Processes,

341, for solvent polishing processes within the class definition.

432, Heating, appropriate subclass for a residual apparatus for the application of heat to material. See the references

to other classes having heating apparatus collected under the search notes to the definition of Class 432.
