Appeal No. 1996-3626
Application 08/302,155
appellants' claimed invention.
Claim 1. A method of improving the efficiency of material
processing and combustion systems wherein the use of
reactants is minimized and the area of uniform deposition
of heat or materials delivered to a substrate surface is
maximized, comprising the steps of:
causing an entrant reactant gas to flow in a
radially uniform fashion, the flow directed substantially
perpendicular to a substrate;
maintaining the entrant reactant gas at a
substantially uniform temperature;
constraining the reactant gas flow at a dividing
streamline while maintaining stagnation flow wherein
heat and mass flux to the surface of a substrate are
substantially radially uniform; and
maintaining the substrate at a uniform temperature.
Claim 2. The method of claim 1 wherein the reactant
gas flow is constrained at the dividing streamline
by means of a coaxial flow of two different gases in
which the flow of an inner reactant gas is contained
within an outer flow of second gas further
constraining the inner gas flow to follow the
streamlines of ideal stagnation flow.
Claim 8. The method of claim 1 wherein the dividing
streamline is maintained by means of a fixture whose
shape conforms to the shape of said dividing
streamline.
THE REJECTIONS
