DEFINITION

Classification: 427/256

(under the class definition) Processes wherein the coating (1) is applied only to selected portions of a base, (2) is applied in such a manner as to produce a coating of nonuniform thickness or (3) varies from area to area as to chemical or physical properties.

(1) Note. The intent has to be form a nonuniform coating; merely coating a rough base which automatically results in a nonuniform coating thickness is not provided for in this subclass.

(2) Note. This subclass provides for applying coatings wherein the only difference in composition of various areas in the color.

(3) Note. A foamed coating is not considered to be nonuniform for the purpose of this subclass unless the disclosure specifically sets forth it is nonuniform.

(4) Note. Merely drilling a hole in a coated base is not provided for here. However, drilling large numbers of holes in a coated base to obtain a nonuniform coating is provided for here.

(5) Note. Partial immersion of a pole to impregnate only the end which will be underground is excluded from this subclass and its indents and is provided for in subclass 441. SEE OR SEARCH THIS CLASS, SUBCLASS:

63, for a coating process which results in a superconductor having a nonuniform coating.

68, for a coating process resulting in a fluorescent or phosphorescent electrical product having a nonuniform coating.

75, for a coating process resulting in a photosensitive electrical product having a nonuniform coating.

102, for a coating process which results in an electrical resistor having a nonuniform coating.

140+, for restoring or repairing which may result in a nonuniform coating.

143, for stencil blank making.

145, for making a developable latent image.

180+, for applying particle to a base, especially subclass 222 where localized different areas are produced.

197+, for applying particles to localized areas of a base. 230+, for a nonuniform coating applied to a hollow article to form a gasket.

466+, for a coating process utilizing electrostatic attraction or projection which may result in a nonuniform coating.

595+, for a process of forming a nonuniform coating by selective irradiation or for a coating process wherein infrared energy or radiant heat is utilized to form a nonuniform coating.
