Abstract (en)
[origin: ES486094A1] Magnetic actuator arrangement in which the actuator or armature is retained in a cocked position by unidirectional magnetic flux having a density that cyclically varies in magnitude with time and is released by selective energization of a bucking coil to counteract the retention flux when the flux density is less than maximum. The modulated retaining flux may be made sufficient at its maximum density to retract the released actuator to the cocked position.
