Appeal 2007-3126
Application 10/359,275
The appeal is hereby dismissed with respect to the § 112, ¶ 1 rejection,
which was withdrawn at page 3 of the Answer.
We affirm the § 103(a) rejection.
A. The invention
Appellants’ invention is a high-voltage vacuum switching device in which
the axially movable operating rod that controls the position of the movable contact
contains resistors of a voltage-sensing circuit. More particularly, the operating rod
is tubular and the resistors are supported therein by an elastic filling compound that
is different from the material of the operating rod.
B. The claims
The independent claims are claims 1 and 21, which read:
1. A vacuum device, the device comprising:
a vacuum assembly having switching contacts disposed therein,
one of the switching contacts being a movable switching contact that
is movable along an axis;
a tube disposed along the axis and operable to actuate
movement of the movable switching contact along the axis;
a sensor disposed within the tube;
an elastic compound that encapsulates the sensor, is provided
within the tube, and is made from a material different from a material
of the tube.
21. A vacuum switching device including an operating rod, the
operating rod comprising:
a radially-wound, epoxy glass tube;
a sensor disposed within the tube; and
