Definition

This class provides for (1) processes and/or apparatus for making stock or articles of those ceramic masses, which generally include a "glass former" or an oxide which approaches glass forming properties, in their composition and which are formed by fusion of raw materials (generally mixtures, most of which are of an earthy nature - as distinguished from metallic, organic, etc., - silicon, silica, and slag are included) at ordinary high furnace temperatures, by working (molding, shaping, etc.) of the mass after being melted or changed to a plastic or softened state by heating; and (2) processes and/or apparatus for treating stock or articles made by (1) above unless otherwise provided for as shown in Lines With Other Classes and Within This Class and References to Other Classes, below.

The use of hazardous or toxic waste to make a glass material a useful product is provided for herein, however, vitrification of hazardous waste for purposes of containment is excluded, see References to Other Classes below.

Included within the scope of the class definition are:

(1) Glass fiber or filament and mineral wool making.

(2) Manufacturing processes and/or apparatus including a step of, or means for adhesively bonding glass directly to another part by welding with or without use of an intermediate ceramic or vitreous material.

(3) Manufacturing processes and/or apparatus including a step of, or means for forming a glass article from molten or softened glass.

(4) Processes and/or apparatus including a step of, or means for treating glass while in a molten or solid state.

(5) Processes and/or apparatus including a step of, or means for treating a glass preform to change a physical or chemical property thereof.

(6) Processes and/or apparatus for repairing or cleaning glass working or treating apparatus.

Search notes relating to (a) processes and apparatus and (b) products will be identified appropriately.

LINES WITH CLASS 23, CLASS 117, AND CLASS 438

Although silicon and silicon dioxide are arbitrarily considered to be glass materials for Class 65, a process of growing these polycrystalline materials is proper for Class 23, even though a rod is used as a bait, unless the shape formed is not a result of crystallization or deposition on the rod. If crystallization is combined with specific glassworking and/or treating of silicon or silicon dioxide, the process is proper for Class 65, but see Class 438 for semiconductor device manufacture. Processes of growing single-crystal of all types of materials, including silicon or silicon dioxide, are proper for Class 117. The proper placement of the original of a patent claiming a Class 23 and/or Class 117 species of crystallization and a Class 65 species, or having multiple disclosure with only generic claims, is Class 117 first, then Class 23, then Class 65.

LINES WITH CLASS 422, CLASS 23, AND CLASS 148

See Class 422, Chemical Apparatus and Process Disinfecting, Deodorizing, Preserving, or Sterilizing, subclasses 245.1+ for apparatus directed to crystallizing a material within the class definition of Class 23. Although silicon and silicon dioxide are arbitrarily considered to be glass for Class 65, a process of, or apparatus for, growing crystals of these materials is placed in Class 23 (for a process exception, see (5) Note in Class 148, subclasses 1.5+) even though a rod is used as a bait unless the shape formed is not a result of crystallization or deposition on the rod. A combination of crystallization and specific glassworking and/or treating silicon or silicon dioxide is placed in Class 65. A patent claiming a Class 23 species of crystallization and a Class 65 species or having a multiple disclosure with generic claims only is classified in Class 23.

LINES WITH CLASS 438 AND CLASS 437

Class 438, Semiconductor Device Manufacturing: Process, for the combination of Class 437 unit coating operation or Class 437 unit etching operation with glass melting, shaping or forming, joining, or heat treating. Moreover, Class 438 also takes the heat treating, per se, of Class 438 semiconductor material if for purposes of modifying the electrical properties thereof.Additionally, various classestake mounting or packaging operations of semiconductor devices when glass melting, glass shaping, glass forming, or glass heat treating is combined with any coating, adhesive bonding, metal casting, metal working/deforming, metal fusion bonding, or other chemicalor mechanical manufacturing operation. See notes therein for a detailed explanation of the relevant lines.
