DEFINITION

Classification: 219/385

(under subclass 200) Apparatus including significant details of at least one heating device combined with a container, enclosure or support means for the material to be heated and wherein the combination claimed is not specifically provided for above or in another art class.

(1) Note. Class 219 is the generic class for electric heating. Class 373 is specific to the electric furnace structures or method for electrically melting or fusing refractory materials, usually granular in nature (ores, oxides, sulphides, etc.), the materials having a melting point of lead or above. Class 373 also provides for the electrically stirring of such high temperature melts. Class 373 also provides for electrical furnaces for melting or treating glass or silica (subclasses 27+) and for treating carbon (subclasses 109+). Subclasses 17 and 139 of Class 373 provides also for miscellaneous electric furnaces, such as the zone refining or melting type (e.g. semiconductor materials) and wherein electric furnace structure is claimed. See, also, the definition of Class 373 and the reference to

Class 373 under Search Class in the class definitions of Class 219.
