Isolator system providing low attenuation for input signals and extremely high attenuation for signals attempting to pass in the reverse direction

Claim 1

AN ISOLATOR SYSTEM FOR SUPPLYING DESIRED ELECTRICAL SIGNALS FROM A COMMON SOURCE TO A PLURALITY OF INDEPENDENT DEVICES CONTROLLED BY THE SIGNALS FROM SAID SOURCE AND IN OPERATION WHEREIN SAID DEVICES ARE EFFECTIVELY ISOLATED FROM ONE ANOTHER BY STRONGLY ATTENUATING UNDESIRED SIGNALS ORIGINATING IN ANY ONE OF SAID DEVICES AND ATTEMPTING TO PROGRESS BACK TOWARD SAID COMMON SOURCE, SAID SYSTEM COMPRISING A COMMON SOURCE, A PLURALITY OF ISOLATOR CIRCUITS HAVING THEIR INPUT TERMINALS COUPLED TO SAID COMMON SOURCE, AND A PLURALITY OF SAID CONTROLLED DEVICES EACH COUPLED TO THE OUTPUT TERMINALS OF A RESPECTIVE ONE OF SAID ISOLATOR CIRCUITS COMPRISING AN ELECTRONIC AMPLIFIER STAGE HAVING A CONTROLLED ELECTRODE, A CONTROL ELECTRODE, AND A COMMON ELECTRODE; VARIABLE RESISTANCE MEANS; A SOURCE OF ELECTRICAL POWER; CIRCUIT MEANS CONNECTING SAID SOURCE IN SERIAL RELATIONSHIP WITH SAID COMMON ELECTRODE, SAID CONTROLLED ELECTRODE, AND SAID VARIABLE RESISTANCE MEANS; THE INPUT TERMINAL BEING CONNECTED TO SAID CONTROLLED ELECTRODE; SECOND RESISTANCE MEANS CONNECTED BETWEEN SAID INPUT CIRCUIT AND SAID CONTROL TERMINAL; AND SAID OUTPUT TERMINAL BEING CONNECTED TO SAID CONTROL ELECTRODE.
