Abstract:

A modular solvent extraction plant for extracting metal from a metal are is provided. It includes a stage-wise, plug flow contactor that mixes an aqueous solution and an organic solvent solution into a mixed emulsion, a reactor to further mix the solutions, a separator for breaking up the emulsion into an aqueous solution and an organic solution, and a loaded organic coalescer that removes aqueous entrainment. It may also include a raffinate coalescer that removes organic entrainment, a second stage-wise, plug flow contactor that mixes an electrolyte solution with the organic solution from the loaded organic coalescer to form a second mixed emulsion, a second reactor, a second separator for breaking up the second emulsion, and an electrolyte coalescer. An organic scrub station may be used in place of the loaded organic coalescer. The contactors, reactors, separators, and coalescers can be mounted on movable structures.

Abstract:

A cervical inspection device includes a sealing body defined by an outer perimeter and being constructed for sealing placement about the vaginal introitus of a patient, the sealing body having an opening for introducing gas under pressure into the vaginal vault of the patient; and an extendable member connected to the sealing body in a region radially inwardly relative to the outer perimeter of the sealing body and being extendable in a direction transverse to the perimeter of the sealing body to form a generally tubular sheath.
