Abstract: Cable is stored a receptacle by a coiling mechanism. In the coiling mechanism, an arm receives the cable at an axis, and supports the cable as it passes from the axis to a feed end located at a point radially spaced from the axis. A cable driver forces the cable into the arm at the axis and toward the feed end. And an arm driver assists rotation of the arm about the axis while the cable is being forced into the arm at the axis.

Abstract: The instant invention is a strap for installation over sheathing to hold the sheathing to an underlying structural frame member through the use of interconnecting bands and saddle. The saddle is positioned on the underside of a structural member and receives the bands. Tabs are provided at both ends of the sheathing strap to receive the connecting bands and are also used to align the strap with an underlying structural member. Patterns of through holes are provided in the strap as a fastener alignment guide and are to be used for installation of fasteners after the strap is aligned with the underlying structural member.

Abstract: A trolley to convey brushes for cleaning a stationary hull is drawn along the bottom and sides of the hull. Brushes are supported by variable buoyancy chambers to make the biasing of the brushes against the hull also in turn variable. The trolley can be supported and stored in a dock or alternatively supported by a floating platform. There is an electrical motor drive for a chain which pulls the trolley. A diesel prime mover may be used in the floating platform to generate power for the electric motor chain drive and for the submersible motors.
