Abstract

Improvements in electrical meter circuits comprising junction transistors, characterized in that they comprise at least three phases or periods connected in a chain, each phase including a single junction transistor that has a base electrode, a collector electrode and an emitter electrode; an impedance connected in the emitter-collector circuit of the transistor in each phase; means to apply the voltage developed through the impedance in each phase, to a point of the transistor base circuit in each of the other phases, via a rectifier connection, so that when any one of the phases is in a first condition driving, all other phases are forced to go into a second driving condition; and means to drive each phase, in turn, to place it in the first mentioned conduction condition, in response to the application of successive pulses to the circuit.
