Application No. 08/207,512
only other remaining claim that is pending in this application
has been indicated as allowable by the examiner (Final
Rejection, mailed December 22, 1994).
BACKGROUND
The appellant's invention relates to a grease composition
including fluorinated polymer oils and boron nitride.
According to appellant, enhanced lubricating properties may be
obtained if the boron nitride is utilized with a bimodal
particle size distribution (Specification, page 3). An
understanding of the invention can be derived from a reading
of exemplary claim 1, which is reproduced below.
1. A grease composition comprising:
(A) between 5 and 45 weight percent of a thickening
agent comprising boron nitride powder having a bimodal
particle size distribution in which between 25 and 75 weight
percent of the boron nitride has an average particle size in
the range of from 2 to 50 micrometers and between 75 and 25
weight percent of the boron nitride has an average particle
size in the range of from 0.01 to 1 micrometer; and
(B) between 55 and 95 weight percent of a liquid
fluorinated polymer oil.
