Appeal No. 1999-1134
Serial No. 08/334,465
directed to a non-elected invention . Claims 1-10, 12, 14 and2
18-21 have been canceled.
The invention relates to a dynamoelectric machine having
protuberances to improve the rate of heat transfer within
radial ducts through stacked rotor turns (specification, page
1, lines 6-9). More particularly, protuberances (figure 5,
item 42a) are formed in radial holes (figure 5, item 26a)
which are formed through the stacked turns (figure 5, item
18a) to enhance turbulent flow of the cooling medium which
circulates through the rotor windings. Each of the stacked
turns has a protuberance projecting from a first wall surface
thereof. Various embodiments with differing protuberance
placement are disclosed (figures 5-7).
Independent claim 22 is reproduced as follows:
22. A dynamoelectric machine comprising:
a rotor having a plurality of generally radially
extending slots circumferentially spaced from one
another;
windings for said machine including a plurality
of radially spaced rotor turns stacked one on top of
another in each of said slots;
