  • Patent number: 4194180
    Abstract: Apparatus for registering quantity values of corresponding volume or energy quantitites measured at consumption points at a distance from a central station which has a number of counters corresponding to the various consumption points. Each time a predetermined volume or energy quantity has been measured, the corresponding signal transmitter is activated. A signal is then relayed from the transmitter back to the central station where it is initially stored in a shift register device having a length equal to the number of transmitters coupled to the central station. Each of the transmitters is coupled to a distributing device which selectively samples and couples each of the transmitters to the central station as they are activated. Output signals from the shift register device emerge therefrom in synchronism with a subsequent activation of the transmitter to which they correspond. The output signals are then coupled through a switch device to the corresponding counters.
