DEFINITION

Classification: 118/620

(under the class definition) Coating apparatus combined with means to treat the work and/or coating material with electrical or radiant energy.

(1) Note. The energy may be applied, for example, in the form of an electro- static or electromagnetic field or as infrared rays.

(2) Note. Generation of heat in the base caused by the application of electrical energy directly to the work will be found here. Generation of heat in the base by radiation will be found in subclasses 641+. The conversion of electrical or radiant energy into heat and the subsequent application of the heat in a nonradiant form to the work will be found in subclasses 58+.

(3) Note. As between the instant class and that of Class 347, Incremental Printing of Symbolic Information, the latter will take for placement a patent directed to a device of that class and including means to develop by coating a latent image produced by such device. However, recitation of further means to transfer the developed image, if by a coating operation otherwise proper for this class (118), will place the patent in this and indented subclasses.
