Abstract

160,988. Hubbard, W. S., Parsons, I. H., and Ball, A. E. J. Jan. 17, 1920. Electric clocks.-The pendulum A, Fig. 1 of a clock to be synchronized carries an armature B which is periodically pulled into contact with an electromagnet B. Pneumatic clocks.-The pendulum A, Fig. 3, of a clock to be synchronized carries an arm B to which a brake is applied periodically by a pneumatic device C.
