Submersible Diver Tool Power Sources; Electro-Hydraulic and Cryogenic Pneumatic

摘要

Two self-contained and completely submersible power supplies for powering diver operated hand held tools are discussed; one power supply operates pneumatic tools while the other operates closed cycle oil hydraulic tools. Operational evaluations were performed with Navy qualified divers using hand held tools powered by the modules to find whether both concepts were effective as submersible power sources. Refinements necessary are delineated. (Author)
