DEFINITION

Classification: 65/60.1

With coating:

(under subclass 17.1) Processes combined with the step of applying a surface coating material to a glass preform (the coating material usually being an emulsion, dispersion, solution), which is clearly disclosed as leaving a residual

film, layer or continuous deposit on the preform.

SEE OR SEARCH THIS CLASS, SUBCLASS:

23, for a glassworking or treating process combined with destruction or delamination of transitory attached or associated separate material.

24+, for processes of applying a parting or lubricating layer.

30.1+, for process of applying a coating involving a chemical reaction with a glass substrate.

40, for a process of coating a part with a conductive coating for Joule effect heating of the work.

43, for a process of bonding including coating a formed part at the joint interface prior to bonding. 443+, for a process of forming a glass fiber or filament combined with a step of coating the fiber or filament during or subsequent to its formation.

523, for processes of dyeing a siliceous body, and see the search notes thereunder.

106, Compositions: Coating or Plastic, appropriate subclasses for coating compositions, per se.

427, Coating Processes, appropriate subclasses for a coating process including the step of forming a substrate by a glassworking operation by name only, unless the coating is applied to the substrate while hot from the heat of formation, in which case the process is in Class 65. When a preparatory treatment for coating is disclosed as additionally changing the physical characteristics of the glass, the patent is classified in Class 65.
