Appeal No. 96-0306
Application No. 07/709,369
application, which are claims 26 through 32, stand withdrawn from
further consideration by the examiner.
The subject matter on appeal relates to a composition for
use in an automatic transmission fluid or a fluid for a wet brake
system or a friction-depending lubricant which comprises at least
one polyol selected from a specified grouping for increasing
dynamic and/or static coefficients of friction. The appealed
subject matter also relates to a method of increasing dynamic
coefficient of friction in the aforementioned environments via
the use of such polyols. This appealed subject matter is
adequately illustrated by independent claim 1 which reads as
follows:
1. In an oil-based functional fluid composition formulated
for use as an automatic transmission fluid or a fluid for a wet
brake system, the improvement pursuant to which said composition
contains a minor amount in the range of up to about 0.5 percent
by weight based on the total weight of the functional fluid
composition of at least one polyol selected from the group
consisting of ethylene glycol, 1,3-propylene glycol, 1,4-butylene
glycol, trimethylolpropane, pentaerythritol, 2-butene-1,4-diol,
cyclohexanedimethanol, and 1,2-alkanediols having from 3 to 6
carbon atoms in the molecule to increase the dynamic and/or
static coefficients of friction of the frictional surfaces of the
automatic transmission or wet brake system contacted by the
composition.
