through the holes 10c and circumferentially through the
grooves 10b to expand the sleeve. See col. 3, ll. 21-39.
Once the sleeve is fully fitted on the
tube, the compressed air supply is removed and air inside the
tube escapes through passageway 16. Id. at 40-50.
Fellows also discloses a second embodiment (see Fig. 4)
in which the internal diameter of the sleeve 17 is larger than
the external diameter of the tube 10 so that the sleeve can
easily
slip over the tube. In this embodiment, the sleeve grips the
tube by a vacuum applied from inside the tube 10. The vacuum
is directed to the underside of the sleeve 17 by virtue of
circumferential grooves 26 (arranged like grooves 10b in FIG.
1) each connected to the inside of the tube 10 by a single
hole 27. See col. 4, ll. 25-42.
In reading claim 32 on Fellows, the examiner considers
the printing sleeve 17, the oversized tube 10 and the passage
16 in Figure 1 of Fellows to correspond to the claimed
printing sleeve, cylinder and passage, respectively. See
