Appeal No. 1999-0072
Application 08/692,466
application. We reverse and remand the application to the2
examiner for further consideration.
The invention relates to
two-phase fluid flow systems used in industrial
applications such as the steam flooding of oil
fields or fluid distribution systems used in oil
refineries, factories or the like. More
particularly, the invention relates to methods and
apparatus for measuring and controlling
quantitatively in response to the measurements, the
vapor/liquid mixture ratio (steam quality) at piping
junctions in such fluid flow systems [specification,
page 1].
Inasmuch as the copies of claims 1 through 12 appearing
in the appendix to the appellants’ brief (Paper No. 13)
contain numerous inaccuracies over and above those noted on
page 3 in the examiner’s answer (Paper No. 14), we have
referred to the claims as they are officially entered into the
record in reviewing the appealed rejection.
The references relied upon by the examiner as evidence of
obviousness are:
Nogami 3,438,385 Apr. 15, 1969
Statler 5,146,941 Sept. 15, 1992
Stoy et al. (Stoy) 5,415,195 May 16, 1995
2Claim 4 has been amended subsequent to final rejection.
