Appeal No. 1997-0863
Application 08/456,001
viscosity medium into said inlet of said first mixer, said
admixing device including a plate transverse to the flow of
the first medium and having at least one convergent orifice
therein for passage of the first medium therethrough into said
first mixer and a duct adjacent said plate for passage of the
second medium therefrom into said orifice; and
a second mixer connected with said first mixer for
receiving media therefrom, said second mixer having a cross-
sectional flow area that is greater than said cross-sectional
flow areas of said first mixer, wherein said cross-sectional
flow area 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 for
receiving and mixing the media of different viscosities.
14. A static laminar mixing device comprising
a plate disposed transversely of a first flow of flowable
medium, said plate having at least one convergent orifice for
passage of the first flow of medium therethrough;
a duct coaxial of said orifice of said plate for
expelling a second flow of flowable medium into said
convergent orifice for mixing with the first flow downstream
of said plate;
a first mixer having a predetermined cross-sectional flow
area, an inlet for receiving said first and second flows, and
a plurality of static mixer elements disposed along a
longitudinal axis thereof; and
a second mixer connected with said first mixer for
receiving media therefrom, said second mixer having a cross-
sectional flow area that is greater than said cross-sectional
flow area of said first mixer, wherein said cross-sectional
