DEFINITION

Classification: 219/633

Bonding (e.g., nonmetallic, etc.):

(under subclass 618) Subject matter wherein the intermediate member is arranged to transfer heat to permanently unite two or more surfaces together.

(1) Note. Bonding by inductive heat exchange (using an intermediate member to transfer heat) is most common when the materials or workpieces are nonmetallic substances or when bonding metal to plastic using thermal sensitive glue.

(2) Note. Apparatus for operating on the material or object prior to the heating may be included only if the sole purpose of such a preparatory operation is to facilitate the inductive heating.

SEE OR SEARCH THIS CLASS, SUBCLASS:

603+, for bonding metal by direct inductive heating.

765+, for bonding by capacitive dielectric heating.

SEE OR SEARCH CLASS 65, Glass Manufacturing, appropriate subclasses, especially

36+, for a process of bonding glass by a glassworking operation to a preformed part and subclasses 152+ for glassworking apparatus including fusion bonding means.

75, Specialized Metallurgical Processes, Compositions for Use Therein, Consolidated Metal Powder Compositions, etc., appropriate subclasses for bonding particulate metal by heat and/or pressure.

156, Adhesive Bonding and Miscellaneous Chemical Manufacture,

272.2+, for laminating processes which include heating or other effects produced by electrical energy; see subclasses 379.6+ for apparatus therefor.

228, Metal Fusion Bonding, appropriate subclasses for nonelectric metallurgical fusion bonding.

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

460+, for direct application of electrical or wave energy for heating purposes in processes of molding or shaping plastic materials within the class definition and subclasses 109+ for forming articles by uniting discrete, bulk assembled particles.

373, Industrial Electric Heating Furnaces, appropriate subclasses for electric furnaces involving sintering.

419, Powder Metallurgy Processes, appropriate subclasses for processes for making articles by uniting discrete, bulk assembled metal particles.

425, Plastic Article or Earthenware Shaping or Treating: Apparatus,

174+, for means applying electrical or wave energy directly to a workpiece.
