Appeal No. 96-2501
Application 08/177,243
on appeal. Both of these references include numerous "crotches"
where fibrous material, etc. can gather and hang-up and encourage
clogging or plugging of the mixer when fibers, clumps and par-
ticulates are contained within the fluids to be mixed, and both
of these references have structures which obstruct the area along
the longitudinal axis of the mixing conduits therein. Thus, both
of these references have mixing elements which are "in contact"
as that terminology would be understood from appellant's
disclosure, and also fail to define "an open region of travel for
fluids passing through said conduit along its longitudinal axis"
(emphasis added), as recited in independent claim 7 on appeal.
Accordingly, the examiner's rejection of claims 2, 3, 6 and 7
under 35 U.S.C. § 102(b) as being anticipated by Doom and that of
claims 2, 6 and 7 as being anticipated by Kao must be reversed.
Next for our consideration are the examiner's
rejections of claims 2, 3, 4, 6 and 7 under 35 U.S.C. § 102(b)
based on Schulz and of claim 5 under 35 U.S.C. § 103 based on
Schulz.
