DEFINITION

Classification: 522/3

Processes of forming or modifying a solid polymer wherein specific mixing, stirring, agitating, movement of material or directional orientation is employed; or compositions therefore:

(under subclass 1) Subject matter involving specific mixing, stirring, agitating, movement of material or directional orientation; or compositions therefor.

(1) Note. The steps of mixing, stirring, agitating, movement of material or directional orientation must involve a direct relationship with wave energy and not be ancillary to the wave energy exposure. For instance, mixing two ingredients under specific conditions to merely form a composition which is then exposed to a form of wave energy is not proper for this subclass; however, mixing of the same ingredients under the same conditions while said formed composition is exposed to wave energy is proper herein.

(2) Note. Specified for purposes of this subclass requires the naming of a movement imparting rotor, stirrer, impeller or any other device in terms of its specific dimension, design, size, or shape therefor, or requires the recitation of a reactor of a design to facilitate movement or agitation; or requires a positive recitation in the claims as to velocity or designated time of mixing, said time being either continuous or intermittent.

(3) Note. Directional orientation includes adding material horizontally, tangentially, from above or below, etc.

(4) Note. This subclass also provides for those compositions perfected so as to be utilized is a process involving the requirements of this subclass.
