DEFINITION

Classification: 239/419.3

(under subclass 419) Apparatus comprising three dissimilar or different fluids, two of which are mingled upstream of the mixing with the third beyond or at the outlet means.

(1) Note. The fluids must be substantially different in character; two streams of the same fluid differing from each other only in temperature or pressure do not qualify under this definition.
