DEFINITION

Classification: 419/39

(under subclass 38) Specific pressure or lack of pressure recited: Processes which recite a specific pressure during the compaction step or which recite that no nonambient pressure is imposed during the compaction step, i.e., the quantity of pressure employed during the consolidation step is recited in the claims.

(1) Note. A compacting reciting the use of ambient atmospheric pressure, which amounts to compacting by gravitation, is classified herein.
