Claims 1-8 stand rejected under 35 U.S.C. § 103 as being
unpatentable over Pagani in view of Inoue and Zardi.
OPINION
We have carefully considered all of the arguments
advanced by appellants and the examiner and agree with
appellants that the aforementioned rejection is not well

recovery section (in addition to a first recovery section
associated with a first reaction space) for separating urea,
