Appeal No. 2000-1653
Application No. 08/906,586
The claims on appeal are drawn to an in-line mixing
apparatus for the substantially continuous preparation of
liquid mixtures, and are reproduced in the appendix to
appellant’s brief.
The references applied in the final rejection are:
Johnston 5,165,440 Nov. 24,
1992
Arvidson et al. (Arvidson) 5,494,112 Feb. 27,
1996
Claims 1-8 stand rejected under 35 U.S.C. § 103 as being
unpatentable over Johnston in view of Arvidson.
The Examiner’s Position
With respect to claim 1, the sole independent claim on
appeal, the examiner considers that Johnston discloses the
claimed invention generally as claimed, including a first
tubular chamber 2 and a second tubular chamber 18, except for
a flow regulator comprising an adjustable output pump and flow
meter for regulating the amount of component material
introduced in the first chamber via inlet 14. The examiner
takes the position, however, that it would have been obvious
to provide an adjustable output pump and flow meter in
amendments have been entered. See Paper Nos. 11 and 16.
