Class Definition for Class 266 - METALLURGICAL APPARATUS (4206 words) |
| While Class 266 provides for certain methods of operating metallurgical apparatus, those patents which recite a step of treating an ore or molten metal or of altering the parameters effecting such a treatment, e.g., temperature, oxygen content, will not be found in Class 266, unless such a method is less comprehensive than the apparatus. |
| Class 266 provides for furnaces specialized for extracting a desired metallic constituent from a source of such metal, which source could be waste material. |
| Class 266 takes patents having claims to electric furnaces where no electric heating structure is recited and where that structure would be useful in other types of metallurgical furnaces. |
