Application No. 09/078,477
Claims 7, 16 and 17 are representative of the subject matter
on appeal and are reproduced below:
7. A process for coating a granular material with a coating
composition comprising rotating said granular material to provide a
cascading flow of said granular material having a top moving layer,
injecting at least one coating component into said cascading
material at the top moving layer of said cascading granular
material, and recovering said coated granular material for
subsequent use.
16. A process for coating a granular material with a polymer
coating comprising rotating said granular material to provide a
cascading flow of said granular material, applying a first and
second coating component into said cascading granular material from
a plurality of individual applicators, said first and second
coating components being selected to react with one another to form
a polymer on the surface of said granular material at the
temperature of said components and granulars, and recovering a
polymer coated granular material for subsequent use.
17. The process of claim 16 wherein the application of said
first and second coating component is by injecting said coating
components into the cascading material at a top moving layer of
said cascading granular material.
