1 44. “Assume that the shafts are in the operating position shown in
2 FIG. 2. Shaft 20 will be pivoted clockwise to move it into the position
3 shown in FIG. 3 wherein the heads are in interference with pin 38.”
4 (Linn, col. 4, ll. 1-4).
5 45. Likewise shaft 22 is revolved counterclockwise to bring
6 its heads into interference with pin 38'. The shifter 28 and the
7 shifter 30 move from left to right as shown in FIG. 5A, moving
8 all the heads to the right side after the head locking means has
9 been disengaged.
10 The shaft 20 then pivots counterclockwise for a sufficient
11 distance to provide clearance between pin 38 and the heads.
12 The shifter 28 moves farther to the right to bring the pin 38 into
13 the position shown in FIG. 5C. The shaft 20 is pivoted
14 clockwise again to bring the heads and pin 38 into the position
15 shown in FIG. 5C. The screw 34 is rotated to move the shifter
16 from right to left to the to the operating position for the first
17 head as shown in FIG. 5D.

21 46. If any heads are to be idle, they are moved to the extreme left
22 hand position shown in FIG. 5E. Then, with the heads in the
23 orientation shown in FIG. 5E, the locking means locks the
24 heads to the shaft in their operative positions. The shaft 20 is
25 now ready for the next production run. Simultaneously, the
26 heads on shaft 22 would have been moved likewise.

28 (Linn, col. 4, ll. 27-34).
29 From our review of Seki we make the following findings of
30 fact:
31 47. “The present invention relates to an apparatus for determining
32 positions of a plurality of heads which is employable for a slitter
33 scorer on a corrugate machine.” (Seki, col. 1, ll. 7-9).
