Abstract: A quick release bow clamp comprising a hinged circular body having a vehicle mating flange and a nose cone mating flange configured to selectively attach to an access plate on the bow of an underwater vehicle and a nose cone for the same, respectively. The flanges of the bow clamp and the corresponding flanges of the access plate and nose cone may include an intermittent pattern of open and solid portions for weight reduction. The bow clamp may also include a quick release clamp having an adjustable draw latch configured to attach to a clip on the body of the bow clamp and a safety latch configured to prevent the draw latch from inadvertently disengaging with the clip.

Abstract: A tool-less joiner clamp includes a hinged circular body having a forward mating flange and an aft mating flange configured to selectively attach to a forward section flange and an aft section flange of an underwater vehicle, respectively. The forward mating flange has a threaded inner diameter configured to integrate with a threaded outer diameter of the forward section flange, such that rotating the joiner clamp about the forward section flange causes the clamp to move in an axial direction. Also included is a cam lock for selectively closing and tightening the tool-less joiner clamp onto the forward and aft section flanges of the vehicle and may include a quick release mechanism for opening the cam lock. The clamp may also include collapsible handles, and multiple buttons configured to press against a flat surface of the aft mating flange when the joiner clamp is rotated about the forward section flange.

Abstract: An unmanned undersea vehicle including a magnetic coupler drive. The magnetic coupler drive is incorporated into a hull section, such as a tail section of the unmanned undersea vehicle. The magnetic coupler drive includes a motor shaft magnet, a titanium housing disposed about the motor shaft magnet, and a propeller shaft magnet magnetically coupled to the motor shaft magnet, but physically separated from the propeller shaft magnet by the titanium housing.

Abstract: Application of surface marking to metal stock, such as aluminum sheet, prior to or during scrap-generating manufacturing operations, to provide a detectable mark on pieces of manufacturing scrap derived from the marked sheet and commingled with scrap of other aluminum alloy sheet, so that the scrap can be sorted and the marked alloy scrap pieces separated from scrap of other alloy sheet to which the marking was not applied. Different markings, providing detectably different marks, may be respectively applied to sheet of different compositions if scrap pieces of more than two different compositions or compositional families are to be sorted and separated from each other.
