Application No. 08/646,077
rejection presupposes that the artisan would have recognized that the Palmatier apparatus
operates as alleged, even though the reference does not say so.
We cannot dismiss the examiner’s position as insubstantial. For proper operation
of the Palmatier apparatus, the speed of advance of web 12 itself is, of necessity, directly
proportional (i.e., linear speed versus rotational speed) to the speed of the printing press
as measured by tachometer 24 at blanket cylinder 22. Assuming, as does the examiner,
that the register marks are laid out on the web by printing plates on the plate cylinders, the
time difference between occurrences of register marks on the advancing web would be,
similarly, directly proportional to the speed of rotation of the printing plates carried by the
plate cylinders in the Palmatier apparatus. In much the same way that the speed of
advance of a thread indicates the rotational speed of the spool from which it is drawn, the
speed of advance of register marks would indicate the rotational speed of the printing
plates which are responsible for placement of the registration marks.
In this regard we note that appellant discloses a detector 44 (instant Figure 1) for
measuring the speed of the printing press. One embodiment of the detector for measuring
the speed of the “sleeve-shaped printing plate” 12 consists of an optical sensor 42 which
senses “marks (for example, the register marks generally represented as element 50 in
