Low attenuation very high frequency time delay vs. frequency variation correcting network

Claim 1

A TRANSMISSION SYSTEM FOR TRANSMITTING ELECTRICAL SIGNALS WITHIN A BAND OF FREQUENCIES HAVING A CENTRAL FREQUENCY FO, COMPRISING: AN INPUT LINE FOR SAID SIGNALS, AN OUTPUT LINE FOR SAID SIGNALS, AND PHASE-SHIFT NETWORK MEANS OPERATIVELY CONNECTING SAID INPUT LINE WITH SAID OUTPUT LINE AND INCLUDING CIRCULATOR MEANS HAVING A PLURALITY OF BRANCH CONNECTIONS AND AT LEAST ONE CIRCUIT WITH A REACTIVE IMPEDANCE OPERATIVELY CONNECTED WITH AT LEAST ONE OF SAID BRANCH CONNECTIONS, SAID REACTIVE IMPEDANCE HAVING A RESONANT FREQUENCY WITHIN SAID FREQUENCY BAND, SAID REACTIVE IMPEDANCE CIRCUIT BEING CONSTITUTED BY A BAND-PASS FILTER FORMED BY A WAVE-GUIDE CONNECTED AT ONE END THEREOF TO SAID CIRCULATOR MEANS AND A PLURALITY OF RESONANT CAVITY MEANS COUPLED TO SAID WAVE-GUIDE MEANS AT PREDETERMINED SPACINGS ALONG SAID WAVE-GUIDE MEANS, AND FURTHER CAVITY MEANS OPERATIVELY CONNECTED TO THE END OF SAID WAVE-GUIDE MEANS OPPOSITE THE SAID ONE END THEREOF, SAID CAVITY MEANS BEING TUNED SUBSTANTIALLY TO THE FREQUENCY FO, SAID SPACING BEING EQUAL TO AN INTEGER NUMBER OF HALFWAVE LENGTHS WITHIN SAID WAVE-GUIDE MEANS.
