Appeal No. 1997-2216
Application No. 08/392,661
Appellants' invention relates to an overcurrent
protection arrangement including a switching circuit and a
pulse generator which generates pulses up to a predetermined
maximum number or for a predetermined time to reset the
switching circuit when the overcurrent ceases. Claim 1 is
illustrative of the claimed invention, and it reads as
follows:
1. An overcurrent protection arrangement which comprises a
switching circuit which is
(a) intended to be series connected in a line of a
circuit to be protected,
(b) has a conducting state in which it will allow normal
circuit currents to pass, and
(c) has an open state which it adopts when subjected to
an overcurrent, the arrangement including a pulse generator
which takes power from a voltage difference across the
switching circuit and which, when the switching circuit is in
the open state, will generate one or more pulses, up to a
predetermined finite maximum number of pulses, or for a
predetermined time, which will reset the switching circuit to
the conducting state if the switching circuit is no longer
subjected to an overcurrent.
