  • the line may be carried upon payingout gear located either within the flotation chamber, within.
  • a hydrostat may be provided which is adapted to release vor actuate a source of power such as a mechanical or compressed air motor, or to complete a battery circuit for actuating an electric motor, thereby rctating (for example through worm gearing) a drum on which the line is wound or actuating a device to which one end of the line is connected.
