Appeal No. 1996-3626
Application 08/302,155
inherent in the program used for manufacturing the critical
design of the specific reactor's shape which apply to CVD
reactions can be presumed to adhere for the other types of
reactions embraced by appellants' claims is unclear. Further,
whether or not the program applied by appellants would even be
useful in designing and building a system for appellants'
method using coaxial flow of gases to constrain the reactant
gas is not clear. Still further, because it appears from
appellants' disclosure that the "dividing streamline" depends
on numerous process variables, it is also unclear what
constitutes "a dividing streamline" in the context of a CVD
system different from the one described in Example 1 wherein a
diamond film is prepared from acetylene, hydrogen and oxygen
at atmospheric pressure.
We recognize that appellants have disclosed that they
determine the defining streamline by the application of
equations (1) through (7) found on page 10 of their
specification and that a software program for modeling the
reactors for their methods based on equations (1) through (7)
has been developed and used to calculate the shape of the
trumpet bell (see page 11 of the specification). However, the
