A power supply for an electromagnetic force system comprising a slow current pulse system in parallel with a dumping circuit feeding a blocking inductor in parallel with a series of diodes; a fast current pulse system of opposing polarity and parallel to the slow current pulse system and blocking inductor, the fast pulse system including a triggered vacuum spark-gap for discharging the fast current pulse system through a working coil such that the current through the coil decreases rapidly and the magnetic field in the gap decreases substantially while the magnetic field in and behind the work piece decreases only slightly, resulting in a large field gradient across the work piece and the creation of a pulse of tension force on the work piece.

Electromagnetic dent remover power supply

A high efficiency broadband acoustic resonator and absorption panel used for reducing engine noise from high bypass fan jet engines mounted on an aircraft. The panel uses a single layer of cellular honeycomb core with a pair of parallel acoustic septums formed internally in the core for attenuating high and medium frequency sounds during all engine operations as well as the low frequency combination tone and 'buzzsaw' noise experienced during high power aircraft takeoff and cutback engine power settings.
