DEFINITION

Classification: 264/183

(under subclass 178) Processes wherein the bath contains ingredients which react chemically with ingredients in the extruded forming material to coagulate, set or form the element or component.

(1) Note. See the class definition for the general line between this class and composition classes, per se. Where a patent claims only the precipitating or coagulating bath for use solely in formation of indefinite length articles by extrusion of article forming material therein, the patent will go to this class as an original in the appropriate subclass based on the disclosure. Mere recitation of spinning a composition into a reactive bath broadly recited or an "acidic" reactive bath is not considered significant molding but recitation of the pH or pH range of the bath is considered significant.

SEE OR SEARCH THIS CLASS, SUBCLASS:

78, for processes in which a spinning solution containing a dye susceptible material or a material capable of forming a dye is extruded into a setting bath disclosed to contain a reactant capable of converting said material into a colored element.

203, for processes employing a solvent extractive bath.

SEE OR SEARCH CLASS 106, Compositions: Coating or Plastic,

162.1+, particularly subclasses 166.01+ for carbohydrate or derivative containing compositions which may be disclosed to have utility as spinning solutions and see the main line between this class (264) and the composition classes as set out in the class definitions of this class (264) which is relative to patents claiming a process of spinning a specific composition into a reactive bath, per se, or an "acidic" bath wherein none of the ingredients of said bath is named, or where no specific pH is recited.
