DEFINITION

Classification: 137/823

(under subclass 822) Device wherein each said passage lies along a separate line, and said lines converge at a zone

common to all the lines, and the streams are directed toward said common zone.

(1) Note. The device of this subclass is sometimes referred to as a "comparator", especially if the characteristics of two power streams are compared. Such characteristics may include pressure, density, temperature, velocity, viscosity, etc., of the fluid of the streams.

(2) Note. See (1) Note of subclass 834 for further discussion of "interaction region".
