Abstract: A mining riser pipe is extended from above water toward a water bottom containing water bottom resources, and a lower portion of an insertion pipe connected to a lower portion of the mining riser pipe is inserted into the water bottom. A liquid is supplied into the insertion pipe and a rotation shaft extends axially inside both of pipes is rotated to rotate stirring blades attached to a lower portion of the rotation shaft inside the insertion pipe, thereby drilling and dissolving mud S inside the insertion pipe into a slurry form is raised to an upper portion of the insertion pipe by a stirring flow generated by the rotation of the stirring blades, and the raised mud is lifted above the water through the mining riser pipe by lifting force.

Abstract: An ice lift apparatus for lifting ice cubes manufactured by an ice maker comprising a horizontal transporting section, a vertical transporting section and an ice discharge section is provided. The apparatus comprises two endless conveyor members driven by a driving unit, a multiplicity of transverse bars mounted between the conveyor members at an interval slightly greater than the longest side of the ice cube, and a stationary guide member disposed within a region defined by the running path of the endless conveyor members with a distance from the transverse bars located at the side of the forward running path of the conveyor members, which distance lies in a range of about 1/2 to 2/3 of the bar interval. Also, the guide member is so disposed as to cause the distance to decrease progressively toward the ice discharge section.
