DEFINITION

Classification: 239/479

(under subclass 478) Apparatus in which the flow adjusting means can rotate between two operating limits.

(1) Note. In this and the two succeeding subclasses, control is such that intermediate stages of flow modification are provided between the two extremes of whirling and nonwhirling.

(2) Note. See subclass 478, (1) Note, for the difference between this and the subclass referred to.
