Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
118 words
AN ELECTRICAL COIL COMPRISING: A PLURALITY OF TURNS OF CONDUCTOR WIRE FORMING A WINDING SYMMETRICALLY DISPOSED WITH RESPECT TO A CENTRAL AXIS WITH MORE THAN TWO LAYERS OF CONDUCTORS, SAID TURNS OF CONDUCTOR WIRE HAVING A COATING COMPRISING A CONTINUOUS LAYER OF SYNTHETIC RESIN, PRESELECTED OF SAID TURNS OF CONDUCTOR WIRE HAVING AT LEAST FIVE SIDES IN CROSS SECTION FORMED BY COMPRESSIVE FORCES THEREAGAINST BY OTHER OF SAID TURNS OF CONDUCTOR WIRE IN THE RANGE OF 10,000 TO 40,000 POUNDS PER SQUARE INCH, AND AT LEAST SOME OF SAID OTHER TURNS HAVING LESS THAN FIVE SIDES IN CROSS SECTION, SAID COATING CONFORMING TO SAID FIVE SIDES OF SAID PRESELECTED TURNS AND TO THE SIDES OF SAID OTHER TURNS.
Claim 2
Dependent Claim
118 words
AN ELECTRICAL COIL COMPRISING: A PLURALITY OF TURNS OF CONDUCTOR WIRE FORMING A WINDING SYMMETRICALLY DISPOSED WITH RESPECT TO A CENTRAL AXIS WITH MORE THAN TWO LAYERS OF CONDUCTORS, SAID TURNS OF CONDUCTOR WIRE HAVING A COATING COMPRISING A CONTINUOUS LAYER OF SYNTHETIC RESIN, PRESELECTED OF SAID TURNS OF CONDUCTOR WIRE HAVING AT LEAST FIVE SIDES IN CROSS SECTION FORMED BY COMPRESSIVE FORCES THEREAGAINST BY OTHER OF SAID TURNS OF CONDUCTOR WIRE IN THE RANGE OF 10,000 TO 40,000 POUNDS PER SQUARE INCH, AND AT LEAST SOME OF SAID OTHER TURNS HAVING LESS THAN FIVE SIDES IN CROSS SECTION, SAID COATING CONFORMING TO SAID FIVE SIDES OF SAID PRESELECTED TURNS AND TO THE SIDES OF SAID OTHER TURNS.
Claim 3
Independent Claim
108 words
A METHOD OF PRODUCING AN ELECTRICAL COIL COMPRISING THE STEPS OF: FORMING A WINDING OF A PLURALITY OF TURNS OF CONDUCTOR WIRE HAVING A CIRCULAR CROSS SECTION WITH A DIAMETER DO AND COATED WITH AN ESSENTAILLY UNIFORM LAYER OF SYNTHETIC RESIN HAVING A RADIAL THICKNESS HO, THE RATIO DO/HO BEING NOT LESS THAN 18, WITH PRESELECTED TURNS BEING ENCIRCLED BY THE OTHER TURNS, AND COMPRESSING AT LEAST A PORTION OF SAID COIL AT A PRESSURE BETWEEN 10,000 AND 40,000 POUNDS PER SQUARE INCH WHEREIN AT LEAST SAID PRESELECTED TURNS ARE DEFORMED FROM SAID CIRCULAR CROSS SECTION TO A MULTI-SIDED CROSS SECTION BY THE PRESSURE OF SAID OTHER TURNS.
