DEFINITION

Classification: 264/37.1

RECYCLING OF RECLAIMED OR PURIFIED PROCESS MATERIAL (NOT RECYCLED CONSUMER USED ARTICLES):

(under the class definition) Processes in which process materials (e.g., flash, trim, defective products, molding materials from which products are formed, treating materials utilized in the molding process, etc.) which were previously employed in a molding operation, whether from batch or continuous process, are recycled or reused in the same or a different molding operation.

(1) Note. Recycling of consumer used articles (e.g., scrap articles or worn materials, used tires, materials employed in commerce, etc.) or articles intended for consumer use are not considered proper under this subclass. However, recycling of defective or improperly molded articles (e.g., virgin material, etc.) will be considered proper for this subclass.

(2) Note. Merely recycling reclaimed "as is" process material as hereinabove set forth is sufficient for placement in this subclass. It is not essential that a step of purification, reclamation, or separation of the desired process material be present for a process to be proper for this subclass. Thus, recycling of a desired polymeric process material does not require separation from a solvent thereof to be proper in this subclass.

(3) Note. Recycling of heat exchange agents, per se, that directly contact shaped articles or process materials is considered proper under this subclass. However, recycling of heat exchange agents that do not directly contact shaped articles or process materials (e.g., cycling of liquid coolant through hollow mold walls, etc.) are not proper for this subclass.
