Appeal No. 1997-0907
Application 08/291,642
invention substantially as claimed except for the claimed
biasing means (set forth in both independent claims 1 and 4 on
appeal) and the means for adjusting (set forth only in
independent claim 4 on appeal). We agree with this assessment
of Castor, which is easily validated by a general assessment
of the figures of this reference and appellants do not assert
otherwise in the Brief and Reply Brief. In what appears to be
a home position, Castor's disclosed armature comprises the
core 12 and the coil 13 with a cylindrically shaped movable
permanent magnet 16 therewithin comparable to the claimed yoke
and movable magnet. The showing in the home position in Figure
1 is better indicated with respect to the attached shutter
blades in Figure 4. A similar showing is present in the
comparison between Figures 2 and 5, and 3 and 6 as to the bi-
directional rotatability of the movable magnet 16 with respect
to the different directioned current flows which may be caused
to flow in the coil 13. This is succinctly set forth in the
SUMMARY OF THE INVENTION at column 2.
The various gaps shown in Figure 1 of Castor contribute
to the orientation of the movable magnet 16 with respect to
the electromagnet provided by the core 12 - coil 13
