allowable if rewritten in independent form to include all the
limitations of the base claim from which they depend and any
intervening claim. Claims 3, 6, 7, 10, 13 and 15, the only
other claims remaining in the application, have been withdrawn

Appellant’s invention pertains to a “endless belt crawler
type vehicles and in particular to a positive drive rubber
track for such vehicle that has a sprocket up-ratio that [2]
provides correct engagement between the sprocket pins on the
drive wheel and the regularly spaced guide lugs protruding
inwardly from the rubber track” (specification, page 1).
Independent claim 8, a copy of which is found in the appendix
to appellant’s brief, is illustrative of the appealed subject
2The drive wheel up-ratio, Ur, is defined on page 5 of
the specification as:

where Ps is the pitch or spacing between the sprocket pins on
the drive wheel and Pc is the spacing of the guide lugs
protruding inwardly from the rubber track and engaged by the
sprocket pins.
