초록 ▼

A non-explosive separation device for releasably holding together components of equipment or apparatus which are to be separated under controlled conditions. The separation device and method of operation includes a retaining element having a strain concentrated portion which completely cleaves when strained at a predetermined magnitude. Strain is applied to the retaining element by an actuating element which is comprised of a solid state phase change material having a shape memory. The actuating element is deformed to an armed shape at a temperature below the phase-change transition temperature. The device is activated by heating the actuating element through its transition temperature so that it recovers toward its memory shape. The retaining element is strained beyond its ultimate strength so that it cleaves at the strain concentrated portion. One embodiment of the invention provides a method for the non-destructive testing of the integrity and readiness of the separation device as well as a method of calibrating the release point of the device.

대표청구항 ▼

A non-explosive separation device which rapidly separates through the use of an electrical power source, the separation device including the combination of first and second lever arms, means for mounting the lever arms to pivot about a fulcrum, said fulcrum being positioned offset from the midspan of the arms to provide a first-order lever with the fulcrum at a distance from the first common ends of the arms which is greater than the distance of the fulcrum from the second common ends whereby a force applied between the first common ends for pivoting the arms about the fulcrum produces a multiplied force at the second common ends, a retaining element mounted to hold the second common ends of the lever arm in a predetermined orientation, said retaining element formed with a strain concentrated portion which completely cleaves when the strain concentrated portion is strained at a predetermined magnitude, a thin, elongate actuating element comprised of a solid state phase-change material having a shape memory which contracts from an armed shape to a memory shape when heated through the material\s phase-change transition temperature, means for connecting one end of the actuating element with the first end of the first lever arm and for connecting the other end of the actuating element with the first end of the second lever arm, and means for selectively directing electric current from the power source through the actuating element to resistively heat the phase-change material through said transition temperature whereby contraction of the actuating element to its memory shape applies a force between the first ends of the arms which pivots the lever arms about the fulcrum with the second ends of the arms multiplying and applying the force to strain the retaining element to said predetermined magnitude to cause the same to cleave the retaining element and release the arms.
