Abstract: A self-deploying stabilizer for marine anchors is disclosed wherein the silizers fold into a collapsed, compact configuration for easy stowage and automatically self-extend to a working position after anchor deployment for stable anchoring performance. The stabilizers have hinged movable arms which include angled reaction force plates which operate against drag forces created on the plates as an anchor moves through various materials in a marine environment to force the stabilizer arms to move to a fully open position. Springs may be used for assisting or restricting deployment of the movable arms, and lock bolts or break-away shear pins may be provided to retain the movable arms in a desired position.

Abstract: A deepwater propellant embedded anchor system having emergency release menism for separating an anchor fluke assembly from the gun assembly. In an emergency, a sear pin is rotated by a lever and release line to disengage the fluke assembly, thus allowing the fluke assembly and explosive cartridge to drop away and allow water to flood the gun barrel and soak the primer for disarming the anchor system.

Abstract: An explosive propellant cartridge for use in propellant-actuated devices. e cartridge contains only the explosive propellant which is stable and safe when not confined in a vessel capable of high pressure containment and does not contain the less stable fusing element. The propellant is contained in an annular space between concentric tubes with the inner tube being perforated. An elongated fusing element is inserted into the inner tube after the cartridge is secured in the propellant-actuated device.
