Appeal No. 96-3298
Application 08/361,284
Appellants’ invention pertains to an inlet pipe system
for a multicylinder internal combustion engine, and in
particular to an inlet pipe system wherein the effective
length of the inlet pipes can be varied in order to improve
engine performance. A further understanding of the invention
can be derived from a reading of exemplary claim 7, a copy of
which is appended to appellants’ brief.
In rejecting appellants’ claims under 35 U.S.C. § 103,
the examiner has relied upon the references listed below:
Miyano et al. (Miyano) 4,854,271 Aug. 8, 1989
Parr 4,932,369 Jun. 12,
1990
Shillington 4,919,086 Apr. 24, 1990
Claims 7-11 stand rejected under 35 U.S.C. § 103 as being
unpatentable over Miyano in view of Parr and further in view
of Shillington.
Miyano pertains to an intake manifold assembly for a V6
internal combustion engine. With reference of Figures 1 and
2, the manifold includes an intake distributor 33, a first
series of counterclockwise extending pipes communicating with
first cylinder bank 1, and a second series of clockwise
extending pipes communicating with second cylinder bank 2.
