Application 08/302,155
improved efficiency by means of specially designed gas or
reactant systems "whose designs are based on calculations of
the streamlines of ideal stagnation flow." Page 5, lines 23
through 28 of the specification. At page 8, lines 12 through
14 of the specification, appellants disclose that the
"dividing streamline" determines a critical radius at the
inlet plane and at lines 19 through 22, appellants acknowledge
that it is the recognition that the dividing streamline formed
by the flow of gas or mechanical means at the boundary of the
above noted critical region that "is crucial to maintaining
the desirable property of stagnation flow." Appellants
further disclose at pages 10 and 11 of their specification
that for their embodiment wherein the reactant gas is
constrained by mechanical means (the trumpet bell), the design
(shape) of the mechanical means is calculated using a
"software package for modeling one dimensional rotating disk
stagnation flow chemical vapor deposition reactors."
Appellants' claims, however, are not limited to rotating
disk stagnation flow chemical vapor deposition reactors,
chemical vapor deposition reactors or chemical vapor
deposition reactions. Thus, whether or not the presumptions
