Variable capacitance transducer with a radioactive battery

Claim 1

IN A TRANSDUCER, IN COMBINATION: A CIRCUIT INCLUDING A HIGH VOLTAGE D.C. SOURCE COMPRISING A RADIOACTIVE BATTERY HAVING INTERNAL CAPACITANCE SAID BATTERY COMPRISING A CYLINDRICAL MEMBER AND A RADIO ACTIVE EMITTER CENTRALLY POSITIONED WITHIN IT; A VARIABLE CAPACITOR IN SAID CIRCUIT AND MEANS FOR PHYSICALLY ADJUSTING THE CAPACITOR TO VARY THE CAPACITANCE THEREOF; A CONTAINER MADE OF DIELECTRIC MATERIAL HAVING THEREIN SAID RADIO-ACTIVE BATTERY AND SAID VARIABLE CAPACITOR, SAID CAPACITOR BEING IN CLOSE PROXIMITY TO SAID RADIO-ACTIVE BATTERY AND THE RADIO-ACTIVE BATTERY HAVING AN ELECTRODE CONNECTING WITH A FIXED PLATE OF THE CAPACITOR; AND ELECTRICAL RESISTANCE MEANS IN SERIES WITH THE CAPACITOR AND THE HIGH VOLTAGE SOURCE WHEREBY UPON PHYSICAL ADJUSTMENT OF THE CAPACITOR TO VARY ITS CHARGE STORING CAPACITY THERE IS A TRANSFER OF ENERGY BETWEEN THE CAPACITOR AND THE CAPACITANCE OF THE HIGH VOLTAGE SOURCE RESULTING IN A SUBSTANTIAL VOLTAGE DROP ACROSS THE ELECTRICAL RESISTANCE MEANS.
