ABSTRACT:
This disclosure is concerned with the hydraulic lifting or conveying of fluids and any bodies carried therewith, such as solid minerals in ocean mining and the like, from depths far greater than the maximum suction heights of pumps and the like, by a partially gas-filled submerged chamber suspended from a stable surface platform and connected to the open environment by means of pipes connected to a buoy, equipped with pumps, and connected to pipes of smaller cross-section extending to the required depth, with the fluid level in the submerged chamber so deep under the ocean surface that the pressure difference between the inside of the chamber and the surrounding water is greater than the pressure drop caused by the transport of fluid and solid material through the pipe from its lower end to the chamber, and with the materials subsequently transported in nearly neutrally buoyant containers, guided by a paravane.
