Appeal No. 95-2255
Application No. 07/962,035
application, which is claim 12, stands withdrawn from further
consideration as being drawn to a nonelected invention.
The subject matter on appeal relates to a method of
processing the surface of a workpiece wherein a carrier gas
stream containing submicron particles (with a hardness greater
than the hardness of the workpiece surface) is blown against
the workpiece surface at a velocity not less than 50 m/sec
with an incident angle to a perpendicular of the surface being
less than 40° to cause deposition of a layer of the material
of said particles. Further details of this appealed subject
matter are set forth in representative independent claim 10
which reads as follows:
10. A surface processing method comprising the steps of
providing a workpiece having a surface to be processed;
forming a carrier gas stream containing submicron particles
having an average particle size in the range of between 0.01
and 3.0 Fm, said particles being of a material with a hardness
greater than a hardness of the surface of the workpiece; and
then blowing said carrier gas stream at a velocity not less
than 50 m/sec against the surface of the workpiece with an
incident angle to a perpendicular of the surface being less
than 40° to cause deposition of a layer of the material of
said particles.
The reference relied upon by the examiner as evidence of
obviousness is:
