move away from stationary contacts 21 to break the circuit
(column 4, lines 26 through 37). During external control of the
circuit breakers, the external control signal to solenoid coil 49
causes the plunger 48 to retract and pull movable contacts 43 and
44 away from the stationary contacts 37 and 40, respectively, to
break the circuit (column 4, lines 38 through 58). We do not
agree with the examiner's conclusion (Answer, page 4) that in
Borona "the circuit breaker is designated by at least one coded
signal" and "the wiring provided in the arrangement exemplified
by Borona is capable of carrying response signals from the
circuit breaker, such as claimed, as well as coded signals to
such circuit breaker." As indicated supra, nothing of the sort
occurs in Borona.
With respect to Brifman, the examiner contends that
"[e]ach circuit breaker has an individual electronic circuit to
receive coded command signals to turn the breaker on or off, and
also sense the state of the breaker contacts and upon request
send back status codes, which are response signals (Abstract)"
(Answer, page 5). A coded command signal is not sent to the
circuit breaker, but a coded status signal is sent back to the
I/O circuit. The coded status signal is decoded by decoder 23
