Abstract: Life saving garment including an air-filled liner for independent use or for attachment to the jacket of a working suit. The liner has front, rear and expandible collar sections including chest, back and shoulder air compartments. The air mainly occupies the back compartment under normal working conditions and is forced into the upper parts of the sections by water pressure. The expanded shoulder compartments and a buoyant neck ring keep the wearer's head above water.

Abstract: Motion compensated load lifting apparatus for use on marine vessels. Apparatus includes means for maintaining tension in load lifting member during relative motion and means for locking the tensioning means in one direction of motion. Tensioning means includes high and low pressure accumulators which enable compressed fluid to act on linear or rotary drives to apply high and low tension. Load rises and falls with vessel under high tension but weight is mainly offset. Locking means, such as ratchet and pawl or pilot-operated valve, is selected to lift load from vessel at crest of relative motion. Tension can be applied with linear ram, rotary drive or through differential drive.
