Between blade supported radial tip ring and static part:

(under subclass 170.1) Device wherein the means is located between (a) an annulus or shroud centered about the runner's axis of rotation and supported by a runner blade* at a position predominantly at an outermost point of the blade as measured from the runner's axis of rotation and (b) the fixed element.

(1) Note. The annulus or shroud usually comprises a blade ring which is supported by a multiplicity of runner blades, the ring being positioned at an outermost radial point of each blade as measured from the runner's axis of rotation.
