Abstract: The invention relates to an electrical earthing nut (1). In the past these have sometimes vibrated loose, with the result that a failsafe safety device has been rendered inoperable. The invention overcomes this problem by providing a nut (1) that has a nut body (2) having an internal thread (4) to receive a threaded shaft and an external perimeter shaped to receive a tensioning device such as a spanner. Body (2) has opposing generally planar faces 5,6. Threaded apertures (7A, 7B, 7C) are provided on the nut body to receive a bolt (8A) to secure an earth connector (8B) to the nut body (2) and grub screws (8C, 8D). Four raised ribs (9A, 9B, 9C, 9D) are provided on planar face (5) to scrape or cut into a surface against which the nut is to abut. Earthing nut (1) may be used with a cable gland.

Abstract: A structure and method for constructing a non-oil-filled towed array providing a single cable entry point for each channel regardless of the number of hydrophones used to make up a hydrophone group or array is described. The method and apparatus enables uniform buoyancy of the hydrophone array and the primary cable around which the hydrophone array is wound. Uniform buoyancy is achieved through the addition of hollow micro-spheres into a Reaction Injection Molded (RIM) polyurethane material used to mold the hydrophones. Additional buoyancy may be desired adjacent heavier cable sections where connectors and telemetry modules are located. An embodiment enables precise adjustment of hydrophone cable buoyancy by providing precise adjustment of the concentration of hollow glass micro-spheres in areas where more or less buoyancy is desired.
