DEFINITION

Classification: 523/353

Utilizing plural discrete mixing operations in specifically described distinct noninterconnected zones:

(under subclass 1) Process wherein the intentional or desired composition is treated or formed utilizing mixing involving two or more distinct noninterconnected locations or zones.

(1) Note. The term mixing relates to the admixture of materials or to imparting motion to a system which serves to increase or maintain the homogeneity of the system.

(2) Note. Two mixing operations described as performed "separately" will be presumed to be performed in distinct zones or locations, e.g., "separately" mixing A with B and C with D "parallel", or "concurrent" mixing are presumed to be in discrete noninterconnected zones.

(3) Note. Distinctness is indicated by langage showing physical separation of the mixers or by independently performed mixing operations upon different compositions or batches.

(4) Note. Noninterconnected indicates that the mixers are not joined physically, e.g., as by conduits, etc.
