Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
133 words
AN ELECTRIC DELAY LINE COMPRISING AN ELONGATED RIGID METALLIC INNER TUBE, A FIRST SHEATH OF INSULATION OF CONSTANT THICKNESS ON SAID TUBE, A HELICAL WINDING OF INSULATIONCOATED WIRE ON SAID INSULATING SHEATH, A PLURALITY OF TAPS COMPRISING SHORT LENGTHS OF WIRE SPACED ALONG SAID WINDING, SAID INSULATION COATING FORMING A CAPACTIVE CONNECTION BETWEEN SAID TAPS AND SAID WINDING, MEANS FOR HOLDING SAID TAPS ON SAID WINDING, AN OUTER SHEATH OF INSULATION ENCLOSING SAID WINDING AND SAID TAPS, SAID OUTER SHEATH OF INSULATION HAVING A PLURALITY OF SUBSTANTIALLY RADIAL HOLES EXTENDING DOWN TO SAID TAPS, A PLURALITY OF OUTPUT LEADS EACH EXTENDING THROUGH ONE OF SAID HOLES AND CONNECTED TO ONE OF SAID TAPS, AND A PAIR OF INPUT TERMINALS APPLYING AN INPUT SIGNAL BETWEEN SAID METALLIC TUBE AND ONE END OF SAID WINDING.
