Appeal No. 99-0094
Application 08/482,589
thermoplastic hub [10] at a force of about 1½ to 2
pounds of force, in which the hub is produced from a
moisture-absorbing thermoplastic such as nylon or
the like and has been expanded by heating and/or
saturated with moisture to about 10% residual
moisture capacity so that the hub bore is softened;
and permitting the hub to cool and dry at room
temperature whereby residual moisture capacity is
about 2% and a force approximately 10 times the
installation force is required to pull the cannula
axially from the hub [Abstract].
The bore in the hub initially has a diameter smaller than
the outside diameter of the cannula such that when the hub is
cooled after being expanded, softened and press-fitted onto
the cannula the bore shrinks to tightly grip the cannula
between the notched ribs (see Zenick at column 2, lines 6
through 39).
Anticipation is established only when a single prior art
reference discloses, expressly or under principles of
inherency, each and every element of a claimed invention. RCA
