Abstract: A compact floating seal system for sealing a rotating shaft within a structure. The floating seal system has a cylindrical outer seal housing positioned within the structure with a cylindrical internal recessed region formed in the outer seal housing and a retaining flange extending into the internal recessed region. An axial retaining means axially retains the outer seal housing against the structure, and an outer torque member prevents rotation of the outer seal housing with respect to the structure. An inner seal housing is retained within the internal recessed region and abuts the retaining flange for preventing axial movement of the housing. The inner seal housing has a shaft aperture therethrough. First and second sealing member retaining grooves formed within the shaft aperture retain O-rings. A lubricant recess is formed within the shaft aperture between the grooves.

Abstract: There is presented an underwater body and intake scoop, the underwater body aving a wall defining a major portion of the body, the wall being exposed to water during movement of the body through a water environment. The intake scoop includes a recess in the wall of the body, the recess having forward and aft edges extending substantially width-wise of the body and interconnected by generally length-wise extending side edges to form, in plan view, a multi-sided recess with the side and aft edges being rounded to facilitate reduction of turbulence and cavitation. A bottom surface of the recess slopes from the forward edge inwardly of the wall. The recess is in communication with a conduit extending to the interior of the body.
