Abstract: A high-load capability non-explosive cable release mechanism for retaining the adjacent ends of two cables and releasing them upon receiving a signal from a remote source. The cable release mechanism has a casing for housing two non-explosive actuators (NEAs), which also has a center bore for housing a jaw and ramp assembly. Each NEA is connected to the jaw and ramp assembly for independently operating the jaw and ramp assembly to retain or release the proximal ends of the two cables. Upon receiving the signal by any one or both of the NEAs, the jaw and ramp assembly will release the adjacent ends of the two cables from the casing.

Abstract: An improved spool assembly for non-explosive actuators used in electro-mechanical structural separation devices. The spool assembly includes two spool halves each having external surfaces and a generally flat internal surface, a unitary and integral internal member made of an electrically conductive material and having a link-wire portion and two electrical terminal portions, and an external wrap-wire wound around the two spool halves and having a connecting end connected to the link-wire portion of the unitary and integral internal member such that the wrap-wire tightly binds the two spool halves together to form a spool for retaining an external structural member. When an electrical current of a sufficient magnitude is applied through the electrical terminal portions of the unitary and integral internal member, the link-wire portion of the unitary and integral internal member will be heated, which reduces its tensile strength to a magnitude below a tensile stress exerted thereon by the connecting end of the wrap-wire, causing the link-wire portion of the unitary and integral internal member to be broken, which in turn causes the wrap-wire to be loosened, allowing the two spool halves to separate apart which permits displacement of the external structural member.
