turns of the coolant passages, and only Appellants evidence

In response to the Examiner's reliance on Kaminski to8
teach that rotor windings have "hot spots" and curing that
problem by "adjusting the cooling scheme", Appellants point
out that Kaminski deals with longitudinal grooves milled into
end windings, and not rotor body radial ducts as claimed.
Appellants
assert that the cooling scheme for the end turns in Kaminski
has
no applicability to the windings within the rotor not forming
part of the end turns.
The Examiner contends that one of ordinary skill in the9
art would know from the background of the invention section of
Kaminski that the cooling of rotor windings is often
