Appeal No. 1997-3624
Application 08/398,522
housed within the casing, external terminals 26 and 32
disposed on the lid and operatively connected to respective
ends of the capacitor element, a frangible conductor 20
interposed between terminal 26 and the capacitor element, a
flexible diaphragm 23 mounted beneath the frangible connector
and a lug 27 formed on the diaphragm. In the event of a fault
condition within the capacitor element 12, “a build-up of gas
pressure causes the diaphragm 23 to bow inwardly of the cover
21, as shown in Figure 2, breaking or shattering the frangible
conductor 20 and interrupting the flow of current to the
capacitor element 12" (page 4).
In justification of the proposed combination of the
Japanese and British references wherein the Japanese battery
would be modified to meet the above noted claim limitations,
the examiner explains that
[t]he concept of breaking a current breaker
with a pressure sensitive device, wherein the cutter
is an integral part of the pressure sensing means is
seen in the [British reference]. The [British]
reference shows in figure 2, element 23 breaking
element 20. The cutter portion, 27, is an integral
part of the pressure sensing means.
