Contemporary carbon seals exhibit two limitations; first, they require a critical axial pressure between adjacent carbon surfaces and polished wear surfaces, and second, they cannot tolerate slight axial displacement of the seals with respect to their wear surfaces since both conditions allow water to bypass them. A pair of shaft sealing assemblies is included which seal off the juncture between the inner shaft and the outer shaft, and a fitting reaches into the watertight compartment rendering the assemblies independent of axial pressures and slight axial excursions. An angularly displaceable shroud, used to change the direction of the torpedo, is carried on the socket portion of a ball-and-socket joint and is biased to a neutral position by a plurality of bolts carrying biasing springs, spaced in quadrature, to minimize frictional drag between the bolt faces and the socket.，下面是Steerable self-propelled submersible专利的具体信息内容。
