DEFINITION

Classification: 277/346

Diverse and distinct dynamic seals:

(under subclass 345) Dynamic seal includes disparate seal types distinguishable from each other and are for location on associated parts of the joint or juncture to constitute a sealing assembly.

(1) Note. The components forming the sealing assembly may not be part of a single (e.g., removable, etc.) unit.

(2) Note. Seals consisting exclusively of the same type (e.g., lip, mechanical, labyrinth, impeller, etc.) are not proper for this or indented subclasses.

(3) Note. A translatable seal (e.g., floater, etc.) that carries thereon another diverse seal is not distinct.

(4) Note. Cross diverse and distinct dynamic seals into subclasses for the seal types.
