Application No. 08/604,976
ahead of the leading, negative exposure blade where it
would be provided with a negative exposure to establish a
progressively increasing order of blade exposures. Second,
the third blade may be placed between the negative exposure
blade and the zero exposure blade where it would also be
provided with a negative exposure to establish a
progressively increasing order of blade exposures. Third,
the third blade may be placed behind the zero exposure
blade where it would be provided with a positive exposure
to establish a progressively increasing order of blade
exposures. Obviously, the choice of either the first or
second locations would not result in appellants= invention,
and the selection of the third location would amount to
hindsight and thus would be improper as previously noted.
