Appeal No. 1997-3709
Application 08/582,034
Soltis pertains to a thermally balanced vented brake
rotor 14. The thrust of Soltis is the provision of a rotor
having a thickened wall portion at a radial outer location of
the rotor which provides a heat sink that, in use, tends to
counteract the uneven temperature distribution in the rotor
caused by the heat-sink effect of the mounting portion (page
1, lines 62-73). This is shown in Figure 2 at wall 18 which
increases in thickness with increasing distance from the
center of the rotor.
Soltis recognizes (page 2, line 125 through page 3, line
14) that increasing the thickness of wall 18 of vented rotor
14 results in a corresponding reduction in the axially
extending dimension of the air passageways. See, for example,
Figure 2 where the axial dimension of the air passageway at
radial outer end 54 is reduced relative to the axial dimension
thereof at radial inner end 56. Soltis explains that unless
compensated for, this reduction in axial dimension of the air
passageways will cause outlets 54 to be smaller in cross-
the parent application. We note in passing that Kelsey-Hayes
Company, the real party in interest of the present
application, is listed as the “applicant” of the UK patent
application.
