(under the class definition) Apparatus comprising two or more separate and distinct runner* members, the working fluid* passing through one of the runners* in a path of a distinctly
different type than the path it assumes in passing through another of said runners* (e.g., axial and centrifugal working fluid* paths).
(1) Note. The separate and distinct runner* member must be removed as a recognizable runner* subassembly handled as a unit during assembly of the whole device, leaving the other runner* to function as usual. A centrifugal impeller, for example, having blades* which are formed to provide for flow in another path, but which blades* cannot be removed unless destroyed, is excluded under this definition.
(2) Note. Centrifugal and Centripetal flows are considered to be the same type of flow path under this definition.
SEE OR SEARCH THIS CLASS, SUBCLASS:
62, for an apparatus comprising plural runners* mounted for independent or relative movement and in which there are at least two distinctly different runners*, arrangements of blades* or directions of the working fluid* flow paths.
