Appeal No. 95-5020
Application 08/151,041
initiating a partial discharge in said insulating medium. On
page 5 of the brief, Appellant corresponds the waveform
generator recited in claim 52 to the disclosure on page 13 and
Figure 5 of the specification. There, the specification
states that Figure 5 illustrates a typical trigger pulse
generated by the circuit of Figure 4 and the trigger pulse is
superimposed on a low frequency exciting waveform.
On page 4 of the answer, the Examiner points out that
McFerrin teaches a waveform generator that generates a
pedestal waveform of a normal operating voltage. The Examiner
argues that the McFerrin trigger pulse that is superposed on
the pedestal waveform reads on Appellant's claimed trigger
pulse. The Examiner argues that the trigger pulse causes a
breakdown in the faulty cable but does not point to any
specific teaching in McFerrin.
Upon a careful review of McFerrin, we fail to find that
Davis teaches a waveform generator for generating a trigger
pulse
for initiating a partial discharge in the insulating material
or a coupling means for applying the trigger pulse to the
insulating medium so that partial discharge activity is
