Appeal No. 2000-0184
Application No. 08/955,226
to claims 5 through 8 and 10 through 13, leaving for our consideration in this appeal only the examiner’s
rejection of claims 1 and 2 under 35 U.S.C. § 103. Claims 14 and 15 stand allowed. Claims 3
through 13 have been indicated by the examiner as being allowable if rewritten in independent form.
Appellant’s invention relates to gas turbine engines, and, more specifically, to turbine blade and vane
cooling that involves the use of a plurality of specially configured diffusion fan holes (36) spaced apart
along the spanwise axis of the turbine blade so as to provide for increased coverage of the outlets of the
fan holes relative to the blade surface and increased film cooling along the span axis of the blade. A
copy of claims 1 and 2 on appeal may be found in the Appendix to appellant’s brief.
The prior art references of record relied upon by the examiner in rejecting claims 1 and 2 are:
Auxier et al. (Auxier ‘268) 4,767,268 Aug. 30, 1988
Auxier ‘158 5,403,158 Apr. 04, 1995
Claims 1 and 2 stand rejected under 35 U.S.C. § 103 as being unpatentable over Auxier ‘268 in
view of Auxier ‘158.
Rather than attempt to reiterate the examiner's full commentary with regard to the above-noted
rejection and the conflicting viewpoints advanced by the examiner and appellant regarding the rejection,
