Appeal No. 2000-0034
Application 08/473,634
over Mundt taken with Akashi and Aida
Akashi discloses a high frequency magnetic field coupling
arc plasma reactor wherein reaction material which is
introduced into the tail portion of an arc plasma jet can pass
through the central portion of a high frequency plasma flame,
thereby enabling the total energy of the arc plasma jet and
the plasma flame to be utilized (col. 1, lines 9-10; col. 2,
lines 33-47).
Aida is relied upon by the examiner (answer, page 5) only
for a disclosure of a 2.45 GHz frequency microwave energy
source (col. 9, lines 49-50).
The appellants’ claim 34 requires that the chemical
compound flows into the reaction chamber through a conduit
which extends into a portion of the reaction chamber and exits
at a distance away from the member which is at most two times
the distance away from the member where a flow rate of the
chemical compound exiting the conduit does not backflow.
Mundt and Akashi are combinable, the examiner argues,
because both perform chemical reactions (answer, page 6). The
examiner argues that “Mundt appears to have an exit pipe at a
location where back-eddies do not interfere with the main
