TO ALL WHOM IT MAY CONCERN: BE IT KNOWN THAT WE, Joseph G. Gorman, John M. Hicks, and Francis A. Holmes, citizens of the United States of America, residing in the cities of Murrysville, Verona, and Monroeville, respectively, County of Westmoreland and Allegheny, State of Pennsylvania, have invented certain new and useful improvements in a REPULSION COIL ACTUATOR FOR HIGH SPEED HIGH POWER CIRCUITS of which the following is the specification. Abstract of the Disclosure A pair of pancake-like coils have a coil axis substantially colinear with one coil mounted to a framework and the other coil mounted on a movable member. The coils are wound such that when electrically energized simul- taneously the resulting magnetic fields are in opposition, thereby producing a repelling force therebetween. A spring is disposed between the framework and the movable member to urge the movable member in a sense opposite to the repelling force. A power supply is connected to the coil pair providing for a high initial energy transfer and a lower sustaining energy transfer. A shock absorber is mounted on the framework to arrest the moving member which is set in motion by the repelling force. An armature is attached to the moving memeber which enters the field of a holding coil as the moving member is displaced by the repelling force. When the holding coil is energized with the armature situated therein, the moving member is held against the spring force. -1-
