the passageway defines a second center axially extending
dimension (B1) and a second end axially extending dimension
(B2) such that (B2) < (B1). In addition, the first center
axially extending dimension (A1) and the second center axially
extending dimension (B1) are related such that (B1) > (A1).
Finally, the radial outer end of the passageway defines a
first circumferentially extending dimension (A3) and the
radial inner end of the passageway defines a second
circumferentially extending dimension (B3) such that (B3) <
(A3).
The Applied References
Wirth, the examiner’s primary reference, discloses a
vented rotor comprising an annular friction plate 3 having a
radially oriented passageway 6 extending therethrough from a
radially inner end to a radially outer end. Based on Wirth’s
drawing figures, it reasonably appears, and appellants do not
dispute, that the radially oriented passageway 6 is shaped
such that the center axially extending dimension of the inner
end of the passageway is greater than the center axially
extending dimension of the outer end of the passageway (i.e.,
(B1) > (A1)) and such that the circumferentially extending
