Abstract: RECOVERY OF SULFUR FROM SULFUR DIOXIDE        RICH AQUEOUS ABSORBENTS Abstract of the Invention The invention is an improved method for regenerating liquid streams which contain sulfur dioxide.  The method comprises providing a body of liquid which contains sulfur dioxide having a free space above the surface; forming a mixture of gas bubbles in the liquid by admixing a sufficient amount of gas containing hydrogen sulfide with the liquid to react with the liquid to form sulfur and to provide a sufficient amount of gas bubbles to sep-arate sulfur formed from the body of the liquid by flotation. The method is particularly useful for regenerating aqueous absorbents in cyclic processes for removing sulfur dioxide from gas streams.    A preferred method is to admix a sufficient amount of a gas containing hydrogen sulfide with a whirling mass of aqueous absorbent in the body of aqueous absorbent and passing the mix-ture through a zone of stationary apertures wherein the size of the gas bubbles in the mixture is reduced and whereby hydrogen sulfide in the gas is reacted with the aqueous absorbent to form sulfur and the sulfur is floated to the surface of the body of absorbent by the rising gas bubbles and recovered.         The absorbent can be substantially regenerated and a major portion of the sulfur separated from the aqueous absorbent by this procedure.

Abstract: A B S T R A C T        Ammoniacal leach solutions containing nickel and copper (and possibly other base metal values) are treated by first extracting copper, leaving nickel in the raffinate.  The nickel in the raffinate is subsequently extracted with an organic extractant.  The nickel-loaded organic extractant is subsequently stripped with a highly concentrated ammonium salt solution to yield a strip concentrate from which nickel or nickel oxide is recover-able without electrolytic treatment.  To prevent build-up of copper in the nickel extraction circuit, part or all of the organic extractant from the nickel strip circuit is recycled back to the copper extraction circuit where copper in the organic extractant is eventually stripped.          In the copper extraction circuit, the nickel in the re-cycled organic extractant is replaced by copper from the aqueous layer, preventing build-up of nickel in the organic extractant leaving the copper extraction circuit.

Abstract: ABSTRACT OF THE DISCLOSURE     A method and apparatus for recovery of easily evaporable  components from hot gases, e.g. methanol and turpentine, particularly from the expansion vapors of waste liquor such as sulphate black liquor.  Buffer vapors emerging from the heat exchanger are exposed to an indirect heat exchange in one or more successive concurrent or countercurrent evaporators.  The liquid to be evaporated flows downwards along the heat exchanger surfaces of the evaporator to effectively use the heat contained in the hot gases for evaporation of the liquid.          The easily evaporable components contained in such gases can be separated from the other condensates.  The advance of the invention over prior art is in an increased economy of the recovery process

Abstract: ABSTRACT         An improved pump assembly includes a pressure plate having inlet and outlet ports for conducting fluid to and from a pumping chamber.  The pressure plate includes three layers formed by plate sections having major side surfaces which are bonded together to prevent leakage between the layers.  A first one of the plate sections has an outer side surface which is disposed adjacent to the pump rotor.  This first plate section is advantageously made of a wear-resistant material to minimize wear upon rotation of the rotor.  An intermediate plate section is disposed between the first plate section and a second plate section.  The intermediate place section cooperates with at least one of the two outer plate sections to form a passage which interconnects a pair of ports formed in the pressure plate.  In the illustrated embodiment of the invention, the passage is utilized to connect a pair of inlet ports in fluid communication.

Abstract: ABSTRACT OF THE DISCLOSURE     A fish rearing enclosure includes framework which is netted to provide an enclosed space for accommodating marine fish to be cultured.  The sides of the enclosure converge upwardly to terminate at a normally horizontal mouth portion whose area size is considerably smaller than that of the contour in plan of the entire structure.  A slide fastener or fasteners are attached to the mouth portion of the enclosure which can thus be quickly opened and closed by manipulation of the fastener slider or sliders.  The advance in the art is in combined reduced size of the mouth and of the slide fastener which features increase the speed at which the mouth can he closed and manipulated in emergency, for instance when the whole enclosure is to be quickly lowered to protect the culture from "red tide".
