Abstract: A failsafe hose comprising an inlet fitting assembly and an outlet fitting assembly wherein the inlet fitting assembly and outlet fitting assembly are interconnected by an inner conduit and an outer conduit and the inlet fitting assembly further comprises a dissolvable element and a piston wherein the piston held in an open position by the dissolvable element wherein a leak in the inner conduit will result in the fluid being directed to the dissolvable element by the outer conduit and a method for assembling same.

Abstract: An actuator for selectively exerting a force responsive to an increase or decrease in applied electrical energy, including an electrically conductive member slideably seated within an electrically non-conductive frame, a thermally responsive and electrically conductive shape memorizing spring seated within the frame and adjacent to the member for urging the member responsive to the passage of electrical current through the shape memorizing spring. An electrically conductive contact strip is connected to the frame and extends therefrom in contact with the member such that movement of the member from the neutral position toward an optimal position will maintain the member in contact with the contact strip and wherein movement of the member to the optimal position will disconnect the member and the contact strip. A power source for generating energy is electrically connected to the contact strip and to the shape memorizing spring whereby a circuit is formed when the member is in contact with the contact strip.
