Abstract
Floating apparatus for the remote marking of the position of bodies that have fallen in water, comprises a buoyant body which is ballasted on its underside and which on its upper side carries an inflatable standard having a visible signal at its upper end. The inflatable standard is in the form of inner and outer tubes which define between them a hollow chamber that extends lengthwise of the standard and parallel to the standard. A supply of compressed gas, carried by the apparatus, is selectively releasable to fill the hollow chamber to erect the standard.
Claims1
Apparatus for improving safety at sea, comprising a buoyant body, ballast means on the underside of the buoyant body to maintain the buoyant body in an upright attitude in the water, an inflatable standard carried by the buoyant body in a position such that when inflated the standard is erect and rises a substantial distance above the surface of the water, signal means at the upper end of the standard, the standard being hollow and comprising an outer wall and at least one inner wall disposed within the outer wall, the inner and outer walls defining between them at least one hollow chamber that extends continuously full length of the standard parallel to the length of the standard, and means carried by the apparatus to supply compressed gas to the interior of only said at least one hollow chamber.
