DEFINITION

Classification: 523/315

Utilizing streams or masses moving relative to each other at a described angle of coincidence other than mere pouring, e.g., countercurrent mixing, etc.:

(under subclass 1) Process of treating or forming a desired or intentional composition wherein the motion of forming or treating said composition is described by the angle of coincidence of two or more streams or masses in motion relative to each other than mere pouring.

(1) Note. Angle of coincidence refers to the contact of streams or masses of material which are in motion relative to

each other.

(2) Note. The angle of coincidence can be described qualitatively, e.g, stream A mixed transversely into stream B; or quantitatively, e.g., stream A mixed with stream B at an angle of 30 deg. between the streams, etc.

(3) Note. Some aspect of the angle must be described rather than that which is merely inherent in "mixing" at all possible angles.

(4) Note. Where the gravitationally falling mass is in the form of a "curtain" or sheetlike path, directing a stream of material "toward" the curtain is a sufficient qualitative description of the angle since a family of angles relative to the vertical is described.

(5) Note. Included herein is countercurrent mixing, i.e., the relative direction of flow is substantially 180 deg. apart.
