Generator for producing a sequence of harmonic oscillations of a fundamental frequency

Claim 1

A CIRCUIT FOR GENERATING A SEQUENCE OF HARMONIC OSCILLATIONS FROM A FUNDAMENTAL FREQUENCY OSCILLATION, COMPRISING A PARALLEL TUNED CIRCUIT HAVING FIRST AND SECOND BRANCHES, SAID FIRST BRANCH COMPRISING A SERIALLY CONNECTED COIL AND CAPACITOR, SAID COIL HAVING A SATURABLE CORE, SAID SECOND BRANCH COMPRISING AN INDUCTOR, SAID PARALLEL CIRCUIT BEING RESONANT AT SAID FUNDAMENTAL FREQUENCY WHEN SAID CORE IS SATURATED, FIRST AND SECOND TRANSISTORS EACH HAVING A BASE, EMITTER AND COLLECTOR ELECTRODE, MEANS APPLYING SAID FUNDAMENTAL OSCILLATION IN PUSH-PULL BETWEEN THE BASE AND EMITTER ELECTRODES OF SAID FIRST AND SECOND TRANSISTORS, SAID INDUCTOR HAVING A TAP, A SOURCE OF COLLECTOR OPERATING VOLTAGE CONNECTED TO SAID TAP, FIRST AND SECOND DIODE MEANS CONNECTED BETWEEN THE COLLECTOR ELECTRODES OF SAID FIRST AND SECOND TRANSISTORS RESPECTIVELY AND OPPOSITE ENDS OF SAID PARALLEL CIRCUIT, SAID DIODE MEANS BEING POLARIZED TO PASS COLLECTOR CURRENT OF THE RESPECTIVE TRANSISTOR, A PLURALITY OF SELECTION FILTER MEANS TUNED TO THE FREQUENCIES OF SAID HARMONIC OSCILLATIONS, AND MEANS COUPLING SAID COIL TO SAID SELECTION FILTERS.
