Appeal No. 1997-0863
Application 08/456,001
a second mixer defined by an elongated, second tubular
conduit having an inlet in flow communication with the outlet
of the first tubular conduit, an outlet and a cross-section
which is greater than the given cross-section, and a plurality
of static mixer elements arranged longitudinally over a length
of the second conduit and extending across the entire cross-
sectional area of the second conduit so that a cross-sectional
flow area for the media through the mixer elements in the
second conduit is greater than the cross-sectional flow area
for the media through the first conduit.
29. A static laminar mixing device comprising first and
second tubular mixing conduits joined end-to-end for axially
flowing fluid media to be admixed from an inlet of the first
conduit to an outlet of the second conduit, the first and
second conduits having first and second cross-sectional flow
areas
bounded by interior wall surfaces of the respective conduits
which are substantially constant over respective lengths for
the conduits, the second cross-sectional flow area being
greater than the first cross-sectional flow area, a plurality
of first and second static mixing elements serially arranged
over the lengths of the first and second conduits,
respectively, each static mixing element extending
transversely to the axes of the conduits over the entire
cross-sectional flow area of the respective conduits; and
means for introducing the fluid media to be mixed into the
first housing upstream of the second housing. 3
3 We understand the “first housing” and the “second
housing” to be the first conduit and the second conduit as
recited earlier in the claim. This issue is deserving of
correction during any further prosecution of the application
before the examiner.
