Appeal No. 1997-0863
Application 08/456,001
flow areas of said first and second mixers are taken generally
perpendicular to the direction of flow through said respective
mixers, said second mixer including a plurality of static
mixer elements disposed along a longitudinal axis thereof.
25. A static laminar mixing device comprising
a first mixer having a predetermined cross-sectional flow
area, an inlet for a flow of a high viscosity medium and a
plurality of static mixer elements located along a
longitudinal axis of the first mixer;
an admixing device for introducing a flow of a low
viscosity medium into the first mixer; and
a second mixer in flow communication with a downstream
end of the first mixer for receiving the flows from the first
mixer, the second mixer having a substantially constant,
cross-sectional flow area over its length which is greater
than the cross-sectional flow area of the first mixer, the
second mixer including a plurality of static mixer elements
serially arranged between an inlet and an outlet of the second
mixer for mixing the received media.
26. A static laminar mixing device comprising
a first mixer defined by an elongated first tubular
conduit having an inlet, an outlet and a plurality of static
mixer elements serially arranged along a longitudinal axis of
the first tubular conduit for mixing media having different
viscosities, the first tubular conduit having a given cross-
section defining a cross-sectional flow area therethrough, the
static mixer elements extending across the entire cross-
sectional flow area;
an admixing device for introducing a second flow of a low
viscosity medium into the first tubular conduit; and
