Abstract: 687. FÚry, C. Jan. 11. Meters having clock-work controlled electrically. - Two automaticallystarted and electrically - controlled pendulums b are arranged so that there is no solid friction during their oscillation, the circuits for maintaining the oscillation of the pendulums and for registering the differences in the numbers of their oscillations being closed by contacts made by auxiliary pendulums b . Soft-iron cores a, a', carried by the main pendulums b, are magnetized by pressure coils B so as to have consequent poles A in the centre, and are influenced by fixed current coils D. The core limbs a are surrounded by fixed maintaining- coils C, and the limbs a by closed copper rings d carried by the pendulums b . Contacts v, v are thus touched alternately by each auxiliary pendulum. The contacts v are connected to pairs of coils e, e on the stator M of a small rotary-field motor, the rotor of which carries an arm m moving between stops k, k . The number of oscillations of the rotor R is equal to the difference between those of the main pendulums ; a pawl on the arm m actuates a counting-mechanism. The pendulums may be synchronized by known means, for instance by connexion to a slack thread carrying a grain of lead at its centre, or by uniting the actuating-coils of the two pendulums by an adjustable high resistance, or by inversion of the current to be measured without changing the current passing through the fixed coil through which the arm of the pendulum extends. Mechanical registering - means may be employed instead of the electro-magnetic means described.
