Abstract
Abstract A power-actuated system for releasably connecting structures wherein the releasing force does not apply a separation force to the structures being disconnected. Each of the structures to be separated have interlocking flanges along their separation edges which prevent separation in the plane of the structures. In addition, a multiple of releasable locking pins are placed along the mating flanges and when released permit lateral displacement of the structures. When applied to a cylindrical configuration the outwardly directed structure is in section.

Claim 1
Independent Claim
142 words
A power-actuated separation system comprising: a pair of interlocking flange members, one of said flange members having an inwardly directed lip, the other of said flange members having an overlying lip preventing longitudinal movement between said flange members, said other of said flange members having a first lug with an aperture therein, said one of said flange members having a second lug extending over and mating with said first lug, a groove in said second lug and an aperture in said first lug in alignment with said groove, a locking pin extending through said aperture and into said groove, means for moving said pin out of said groove to thereby permit lateral separation between said flanges, said means including a flattened tubing with an explosive therein placed in said groove where, upon detonation, said tubing pushes said pin out of said groove.
