THE INVENTION
The subject matter on appeal relates to a method of
agglomerating and spheronizing a finely divided powder, e.g., a

the three independent claims on appeal, read as follows:
1. A method of treating a finely divided powder
comprising the steps of:
a) forcing the powder through the apertures of a conical
sieve to form agglomerates; and
b) spheronizing the agglomerates.
27. A method of treating a finely divided powder
comprising the steps of:
a) forcing the powder through the apertures of a sieve
having the form of a U-shaped trough to form agglomerates; and
b) spheronizing the agglomerates.
29. A method of treating a finely divided powder
comprising the sequential steps of:
