A COUNTING CIRCUIT INCLUDING A PLURALITY OF COUNT-REGISTERING DEVICES CONNECTED TO EXECUTE A SERIES OF COUNTS, EACH COUNT-REGISTERING DEVICE OCCUPYING EITHER AN ODDNUMBERED OR EVEN-NUMBERED POSITION IN THE COUNTING SERIES AND THUS BEING DESIGNATED AN ODD DEVICE OR AN EVEN DEVICE, EACH DEVICE HAVING AN INPUT AND AN OUTPUT, A CONNECTION FROM THE OUTPUT OF EACH EVEN DEVICE THROUGH A DIODE TO THE INPUT OF EVEY OTHER EVEN DEVICE, A CONNECTION FROM THE OUTPUT OF EACH ODD DEVICE THROUGH A DIODE TO THE INPUT OF EVERY OTHER ODD DEVICE, A FIRST AUXILIARY LINE COUPLED THROUGH A DIODE TO THE INPUT OF EACH ODD DEVICE, A SECOND AUXILIARY LINE COUPLED THROUGH A DIODE TO THE INPUT OF EACH EVEN DEVICE, THE OUTPUT OF EACH EVEN DEVICE ALSO BEING COUPLED THROUGH AN AUXILIARY DIODE TO SAID FIRST AUXILIARY LINE, THE OUTPUT OF EACH ODD DEVICE ALSO BEING COUPLED THROUGH AN AUXILIARY DIODE TO SAID SECOND AUXILIARY LINE, SAID AUXILIARY DIODES BEING ORIENTED SO THAT THE OUTPUT OF AN EVEN DEVICE IS ISOLATED FROM THE OUTPUTS OF THE OTHER EVEN DEVICES AND THE OUTPUT OF EACH ODD DEVICE IS ISOLATED FROM THE OUTPUTS OF THE OTHER ODD DEVICES, ALL OF SAID DIODES BEING ORIENTED SO THAT AS EACH DEVICE REGISTERS A COUNT, THE ELECTRICAL POTENTIAL OF ITS OUTPUT IS COUPLED TO THE INPUT OF EVERY OTHER DEVICE, THIS ELECTRICAL POTENTIAL BEING SUCH THAT EVERY OTHER DEVICE IS PREVENTED FROM REGISTERING A COUNT.
