Abstract: The system is an improvement in an apparatus for transferring cable between a driven rotatable spool and a fixed spool where the rotatable spool is mounted on a stub shaft and the fixed spool is coaxially mounted with respect to the rotatable spool along a common axis. The improved combination comprises an arm which is secured to an axle which, in turn, in the absence of other constraints, would be freely rotatably mounted on the stub shaft. The arm extends in a direction substantially perpendicular to the common axis. A planetary pulley is mounted for rotation at the outer end of the arm, the radial plane of the planetary pulley being substantially parallel to the common axis, the planetary pulley being mounted so as to accommodate cable as it is being transferred between the rotatable spool and the fixed spool.

Abstract: A one-piece fairing is provided which is a finite length monolithic one-piece, snap-on, foil-shaped, low drag fairing element of streamlined hydrodynamic shape, having an outer wall formed of high strength material, the fairing element being symmetrical about its central longitudinal axis, and adapted to be associated with a plurality of similar such fairing elements in end-to-end abutting relation on a cable.

Abstract: A novel compound drum hoist is provided herein. It includes a first or outer cable-spooling drum rotatably and drivingly mounted on a first shaft. A second or inner cable-spooling drum is nested within the first drum, and is rotatably and drivingly mounted on a second shaft disposed at an angle of 90.degree..+-.30.degree., but preferably at a right angle to the first shaft. The inner drum is operable to be rotated while the outer drum is maintained stationary, thereby to spool faired cable onto the inner drum. Substantially simultaneously the outer drum is rotated along with the inner drum, thereby to spool faired cable onto the outer drum. Such hoist is thus suitably adapted to wind long lengths of cable with segmented fairings thereon without any significant risk of crushing the fairings.

Abstract: A slamming-resistant sonar dome canoe is provided herein. The canoe generally consists of a shell, e.g., of fiberglass-reinforced plastic e.g., polyester resin with an extensive internal reinforcement of plastic foam, e.g., epoxy foam in the bottom of the canoe, buttressed by an additional but simple lightweight metal framework e.g., steel or aluminum at the mounting flanges and in the upper portion of the canoe interior and preferably bonded thereto by the thermosetting polyester resin. This sonar dome canoe achieves the conflicting requirements for light weight and robustness in a canoe used in a slamming environment.
