Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
141 words
IN THE METHOD OF FORMING A TAPPED COIL OF WIRE ON A RING-SHAPED CORE, THE STEPS INCLUDING MOUNTING A PLURALITY OF WIRES ON AN ELONGATED NARRROW FLEXIBLE STRIP OF NONMAGNETIC INSULATING MATERIAL WITH SUCH WIRES BEING SPACED FROM EACH OTHER AND EXTENDING GENERALLY PARALLEL TO EACH OTHER AND LONGITUDINALLY OF SAID STRIP SAID STRIP BEING MUCH NARROWER THAN THE CIRCUMFERENCE OF SAID RINGSHAPED CORE, SPIRALLY WINDING SAID STRIP WITH SAID WIRES THEREON GENERALLY RADIALLY AROUND SAID RING-SHAPED CORE WITH SAID WIRES BETWEEN SAID STRIP AND SAID RING-SHAPED CORE SUCH THAT ADJACENT TURNS ON SAID STRIP ARE SPACED CIRCUMFERENTIALLY AROUND SAID CORE SAID STRIP COVERING SAID WIRES, AND INTERCONNECTING INDIVIDUAL DIFFERENT ENDS OF DIFFERENT ONES OF SAID WIRES IN A SERIES CIRCUIT SUCH THAT EACH WIRE PRODUCES AN ADDITIVE MAGNETIC FIELD IN SAID RING-SHAPED CORE WHEN CURRENT FLOWS IN SAID SERIES CIRCUIT.
Claim 2
Dependent Claim
141 words
IN THE METHOD OF FORMING A TAPPED COIL OF WIRE ON A RING-SHAPED CORE, THE STEPS INCLUDING MOUNTING A PLURALITY OF WIRES ON AN ELONGATED NARRROW FLEXIBLE STRIP OF NONMAGNETIC INSULATING MATERIAL WITH SUCH WIRES BEING SPACED FROM EACH OTHER AND EXTENDING GENERALLY PARALLEL TO EACH OTHER AND LONGITUDINALLY OF SAID STRIP SAID STRIP BEING MUCH NARROWER THAN THE CIRCUMFERENCE OF SAID RINGSHAPED CORE, SPIRALLY WINDING SAID STRIP WITH SAID WIRES THEREON GENERALLY RADIALLY AROUND SAID RING-SHAPED CORE WITH SAID WIRES BETWEEN SAID STRIP AND SAID RING-SHAPED CORE SUCH THAT ADJACENT TURNS ON SAID STRIP ARE SPACED CIRCUMFERENTIALLY AROUND SAID CORE SAID STRIP COVERING SAID WIRES, AND INTERCONNECTING INDIVIDUAL DIFFERENT ENDS OF DIFFERENT ONES OF SAID WIRES IN A SERIES CIRCUIT SUCH THAT EACH WIRE PRODUCES AN ADDITIVE MAGNETIC FIELD IN SAID RING-SHAPED CORE WHEN CURRENT FLOWS IN SAID SERIES CIRCUIT.
Claim 3
Dependent Claim
102 words
A TAPPED COIL ON A RING-SHAPED CORE, INCLUDING A RING-SHAPED CORE, A NARROW ELONGATED STRIP OF NONMAGNETIC INSULATING MATERIAL, A PLURALITY OF PARALLEL EXTENDING WIRES MOUNTED LONGITUDINALLY ON AND UNDER SAID STRIP, SAID STRIP BEING MUCH NARROWER THAN THE CIRCUMFERENCE OF SAID RING-SHAPED CORE AND BEING SPIRALLY DISPOSED AROUND SAID CORE SUCH THAT ADJACENT TURNS OF SAID STRIP ARE SPACED CIRCUMFERENTIALLY AROUND SAID CORE MEMBER, AND INDIVIDUAL DIFFERENT ENDS OF DIFFERENT ONES OF SAID WIRES BEING INTERCONNECTED IN A SERIES CIRCUIT SUCH THAT EACH WIRE PRODUCES AN ADDITIVE MAGNETIC FIELD IN SAID RING-SHAPED CORE MEMBER WHEN CURRENT FLOWS THROUGH SAID SERIES CIRCUIT.
Claim 4
Dependent Claim
102 words
A TAPPED COIL ON A RING-SHAPED CORE, INCLUDING A RING-SHAPED CORE, A NARROW ELONGATED STRIP OF NONMAGNETIC INSULATING MATERIAL, A PLURALITY OF PARALLEL EXTENDING WIRES MOUNTED LONGITUDINALLY ON AND UNDER SAID STRIP, SAID STRIP BEING MUCH NARROWER THAN THE CIRCUMFERENCE OF SAID RING-SHAPED CORE AND BEING SPIRALLY DISPOSED AROUND SAID CORE SUCH THAT ADJACENT TURNS OF SAID STRIP ARE SPACED CIRCUMFERENTIALLY AROUND SAID CORE MEMBER, AND INDIVIDUAL DIFFERENT ENDS OF DIFFERENT ONES OF SAID WIRES BEING INTERCONNECTED IN A SERIES CIRCUIT SUCH THAT EACH WIRE PRODUCES AN ADDITIVE MAGNETIC FIELD IN SAID RING-SHAPED CORE MEMBER WHEN CURRENT FLOWS THROUGH SAID SERIES CIRCUIT.
