Electric wave frequency multiplier

Claim 1

ELECTRIC CIRCUIT FOR GENERATING FROM THE ENERGY CONTENT OF AN ELECTRIC WAVE HAVING A GIVEN FUNDAMENTAL FREQUENCY AN ELECTRIC WAVE HAVING A SECOND FREQUENCY WHICH IS A HARMONIC HIGHER THAN THE SECOND HARMONIC OF SAID FUNDAMENTAL FREQUENCY, COMPRISING: A RIGID STRUCTURE MADE OF ELECTRICALLY CONDUCTIVE MATERIAL HAVING FIRST, SECOND AND THIRD ELONGATE HOLLOW PASSAGES COMMUNICATING WITH A COMMON HOLLOW REGION IN SAID STRUCTURE AT AN END OF EACH, FIRST, SECOND AND THIRD STIFF ELONGATE ELECTRICAL INNER CONDUCTORS RESPECTIVELY SUPPORTED AXIALLY WITHIN SAID FIRST, SECOND AND THIRD PASSAGES AND EXTENDING TO SAID COMMON REGION, SAID FIRST CONDUCTOT AND THE WALLS OF SAID FIRST PASSAGE CONSTITUING A FIRST CIRCUIT PROVIDING RESONANCE AT SAID FUNDAMENTAL FREQUENCY, SAID SECOND CONDUCTOR AND THE WALLS OF SAID SECOND PASSAGE CONSTITUTING A SECOND CIRCUIT PROVIDING RESONANCE AT SAID SECOND FREQUENCY, SAID THIRD CONDUCTOR AND THE WALLS OF SAID THIRD PASSAGE CONSTITUTING A THIRD CIRCUIT PROVIDING IDLER RESONANCE AT THE SECOND HARMONIC OF SAID FUNDAMENTAL FREQUENCY, MEANS HAVING A NONLINEAR IMPEDANCE CHARACTERISTIC LOCATED IN SAID COMMON REGION AND COUPLED IN COMMON IN SERIED ACROSS ALL THREE OF SAID CIRCUITS, SAID STRUCTURE HAVING FOURTH AND FIFTH ELONGATED HOLLOW PASSAGES WHICH ARE ELECTRICALLY ISOLATED FROM EACH OTHER, FOURTH AND FIFTH STIFF ELONGATED ELECTRICAL CONDUCTORS RESPECTIVELY SUPPORTED AXIALLY WITHIN SAID FOURTH AND FIFTH PASSAGES, SAID FOURTH CONDUCTOR AND THE WALLS OF SAID FOURTH PASSAGE CONSTITUTING AN INPUT BAND-PASS FILTER SECTION CENTERED SUBSTANTIALLY AT SAID FUNDAMENTAL FREQUENCY MEANS COUPLING SAID INPUT FILTER SECTION WITH SAID FIRST CIRCUIT AS ANOTHER INPUT FILTER SECTION, INPUT MEANS COUPLED TO SAID FOURTH CONDUCTOR TO INTRODUCE A SIGNAL CONTAINING SAID FUNDAMENTAL FREQUENCY TO SAID INPUT FILTER SECTIONS, SAID FIFTH CONDUCTOR AND THE WALL OF SAID FIFTH PASSAGE CONSTITUTING AN OUTPUT BAND-PASS FILTER SECTION CENTERED SUBSTANTIALLY AT SAID SECOND FREQUENCY, MEANS COUPLING SAID OUTPUT FILTER SECTION WITH SAID SECOND CIRCUIT AND ANOTHER OUTPUT FILTER SECTION, AND OUTPUT MEANS COUPLED TO SAID FIFTH CONDUCTOR TO COUPLE OUT OF SAID OUTPUT FILTER SECTIONS A SIGNAL AT SAID SECOND FREQUENCY.
