Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
132 words
IN NON-LINEAR RESONANT APPARATUS, IN COMBINATION, A COAXIAL TRANSMISSION LINE SEGMENT REACTIVE AT A GIVEN FREQUENCY F1, NON-LINEAR REACTANCE MEANS COUPLED TO SAID LINE SEGMENT, SAID NON-LINEAR REACTANCE MEANS TERMINATING AT LEAST ONE END OF SAID LINE SEGMENT, AND SAID LINE SEGMENT AND SAID NON-LINEAR REACTANCE MEANS TOGETHER BEING RESONANT AT THE FREQUENCY F1, MEANS TO EXCITE SAID NONLINEAR REACTANCE MEANS AT A FREQUENCY F2 WHICH IS AN INTEGRAL MULTIPLE OF F1, THE AMPLITUDE OF EXCITATION BEING LESS THAN THE THRESHOLD VALUE REQUIRED TO SUSTAIN OSCILLATIONS OF THE SYSTEM AT SAID FREQUENCY F1, AND MEANS TO IMPRESS A WAVE OF FREQUENCY F1 UPON SAID NON-LINEAR REACTANCE MEANS, WHEREBY JOINT EXCITATION AT FREQUENCIES F1 AND F2 PRODUCES AN OUTPUT WAVE AT FREQUENCY F1 COEXTENSIVE IN TIME WITH THE DURATION OF THE JOINT EXCITATION.
Claim 2
Dependent Claim
