n a counter-clock-wise direction in the other. The pendulum-coils are traversed by the pressure-currentin the same sense, so that the one pendulumis retarded and the other accelerated. Thedifierences in speed set up in this manner bythe passage of a current in the main circuitare proportional to… … Aron Clock-meter When no current is flowing in the circuit,the two pendulums oscillate at approximatelyequal rates. Any want of synchronism be-tween the pendulums is neutralised by theaid of a reversing mechanism, which preventsany difference in synchronism being recordedwith no current. Acting…
