ABSTRACT:
A controller (24) is provided to selectively release an initiator (12) having first and second members (14,16) that clampingly engage an object (18) preventing it from moving in an urged direction. A spring wire coil (20) holds the members (14,16) tightly about the object, one coil end affixed to one of the members and the other coil end is held by a pair of link wire loops (82,86) of the controller (24) which is also removably secured to one of the members (14,16) by a bolt (36). When it is desired to release the object (18) an electric current is passed through the link wire loops (82,86) of sufficient magnitude to cause the loops to break, releasing the coil (20) to unwind and, in turn, release the object for urged movement.
