Appeal No. 2003-0079 Page 4
Application No. 09/532,114
Claim 6 sets forth the invention in the following manner:
6. An internal combustion system for use with a dual fuel source
comprised of a primary fuel stream comprised of an amount of acetylene
and a secondary fuel stream comprised of a fuel other than acetylene,
said internal combustion system comprising:
(a) a conduit having a first end and a second end, said first
end adapted for accepting an air source and said second
end being affixed to a combustion engine;
(b) a throttle valve disposed within said conduit between
said first end and said second end to regulate airflow
through the conduit into said combustion engine;
(c) a secondary fuel line received by said conduit between
said throttle valve and said second end for delivering a fuel
other than acetylene to be combined with said air source in
said conduit for subsequent combustion in said combustion
engine; and
(d) a primary fuel line received by a fuel intake port of said
internal combustion system at a location downstream of said
throttle valve for delivering acetylene fuel directly into said
combustion engine for combustion.
We shall look first at the rejection of claim 6. In setting forth this rejection, the
examiner initially has taken the position that "[t]he mere recitation of primary and
secondary with respect to fuels is deemed at best a method of operation and is
unsupported by any structure," and that the ratio of fuels "is deemed a matter of choice
depend [sic] upon such clear factors as cost, mpg, availability, emissions" (Paper No.
18, page 2). Thus, the examiner has determined that the designation "primary" and
