Electrodynamic drive for synchronous circuit interrupters

Claim 1

THE COMBINATION IN A SYNCHRONOUS-TYPE ALTERNATING CURRENT CIRCUIT INTERRUPTER OF CONTACT MEANS SEPARABLE TO ESTABLISH AN ARC, MECHANICAL LINKAGE MEANS FOR EFFECTING OPENING OF SAID CONTACT MEANS, MENS DEFINING A MAGNETIC CIRCUIT HAVING AN AIR GAP, A MOVABLE CURRENT-CARRYING LINKAGE MEANS DISPOSED AT LEAST PARTIALLY WITHIN THE AIR GAP AND INCLUDING SUBSTANTIALLY RIGID CONDUCTOR BARS WITHIN THE AIR GAP ANS FLEXIBLE CONDUCTORS EXTERNALLY OF THE AIR GAP, CONNECTING MEANS MECHANICALLY INTERCONNECTING THE TWO LINKAGE MEANS, COIL MEANS ENCIRCLING THE MAGNETIC CIRCUIT UTILIZING AT LEAST A PORTION OF THE LINE CURRENT PASSING THROUGH THE SYNCHRONOUS-TYPE CIRCUIT INTERRUPTER TO ENERGIZE THE MAGNETIC CIRCUIT, WHEREBY THE CURRENT INDUCED IN THE MOVABLE LINKAGE SYSTEM MOVES THE COMPONENT PARTS THEREOF NEAR A CURRENT ZERO TO EFFECT CONTACT SEPARATION CLOSE TO A CURRENT ZERO ON THE ALTERNATING CURRENT WAVE.
