Abstract

306,102. Allgemeine Elektricitõts- Ges. Feb. 15, 1928, [Convention date]. Track apparatus actuating signals other than on trains; recording movements of trains. - A momentary impulse in a circuit including a magnet c of a. counting device is produced as each wheel of a train passes between two magnetic cores a, b, a coil on one of which is energized by intermittent direct or alternating current and a coil on the other, which is in direct series with the magnet c, has induced in it an impulse due to the change of flux in it as each wheel passes between the cores. The cores may be mounted on a non-magnetic base. The cores may be omitted, the coils alone being used when the current supply is of high frequency.
