Appeal No. 1998-0023
Application 08/470,374
substantially parallel to the second tubular conduit and the
mixer elements therein; and
with the second flow substantially completely occupying
the second cross-sectional area of the second conduit so that
a cross-sectional flow area for the media through the second
conduit is greater than the cross-sectional flow area for the
media through the first conduit.
27. A method of mixing first and second fluid media of
differing viscosities comprising the steps of joining first
and second tubular mixing conduits end-to-end, axially flowing
the fluid media to be admixed from an inlet of the first
conduit to an outlet of the second conduit, providing the
first and second conduits with first and second cross-
sectional areas bounded by interior wall surfaces of the
respective conduits which are substantially constant over
respective lengths of the conduits, the second cross-sectional
area being greater than the first cross-sectional area,
serially arranging a plurality of first and second static
mixer elements over the lengths of first and second conduits,
respectively, each static mixing element extending
transversely to the axes of the conduits over the entire
cross-sectional area of the respective conduits; and
sequentially flowing the media through the first and second
conduits at respective flow rates which are inversely
proportional to the first and second cross-sectional areas.
28. A method of mixing first and second fluid media of
differing viscosities comprising the steps of forming a
continuous flow of the media along first and second, serially-
arranged portions of a confined flow path, subjecting the
media in the first and second portions of the flow path to
mixing action, and enlarging a cross-sectional area of the
flow path in the second portion relative to a cross-sectional
area of the flow path in the first portion so that the media
flow along the entire second portion of the flow path at a
rate which is less than a rate of flow in the first portion.
