 Appl.No PCT/GB1989/000806 Applicant RUSSELL, James, Robertson Inventor RUSSELL, James, Robertson
The present invention relates to pumps that use reverse osmosis to drive a liquid therethrough. The liquid pump of the present invention comprises a semi-permeable membrane (2) adapted to operate under reverse osmosis when the pump is in operation, which membrane (2) separates two solutions (4, 5) of differing concentrations of the same or different solute in a common solvent, wherein the pressure on the membrane of the more concentrated solution (4) is sufficiently high when the pump is operating for reverse osmosis to occur, and wherein the said pressure is generated by the hydrostatic head of the more concentrated solution (4), optionally assisted by pressure generated within the solution by normal osmosis. In accordance with the present invention there is provided a machine comprising a first fluid system comprising a first semi-permeable membrane (3') separating two solutions (4', 6') of differing concentrations of a first solute in a common solvent, the first membrane (3') being adapted to operate under normal osmosis when the machine is in operation, and a second fluid system comprising a second semi-permeable membrane (2') separating two solutions (4', 5') of differing concentrations of a second solute in the common solvent, the second membrane (2') being adapted to operate under reverse osmosis when the machine is in operation, wherein the first and the second fluid systems are in fluid connection and wherein the working fluid for the machine is the common solvent which moves between the first and the second systems when the machine is in operation. Preferably the first and the second fluid systems are connected directly by sharing a common solution of the higher concentration of the same solvent, with both solutions of the lower concentration being pure solvent. Most preferably the solute is sugar and the common solvent is water.

 Appl.No PCT/US1990/004896 Applicant AURIAN CORP. Inventor WEBER, Roland, E.
A filtration apparatus characterized by efficiency of the precoating step and maintenance of filtration performance over a long period of time after precoating has been completed. The filter (10) promotes parallel flow of porous precoat material along a porous septum (12), thereby achieving efficient stacking of this material against the septum (12). A dual-speed pumping system (62 et al.) transmits the precoat material to the septum (12) at high velocity, thereby further encouraging efficient stacking, but pumps the fluid to be filtered at a lower velocity to minimize energy consumption.

 Appl.No PCT/AU1990/000327 Applicant THE BROKEN HILL PROPRIETARY COMPANY LIMITED Inventor ENGEL, Malcolm, David
A method for ion flotation in which the flotation reagent employed is a compound of general formula (I), wherein R1 is a C10 - C18 alkyl group, Y is O, S, NH, (CH2)n or (CHR)n where R is a lower alkyl group and n is 1 to 6. X is a halogen atom, and P and Q are the same or different groups and each is hydrogen or a lower alkyl, lower alkenyl, aryl or substituted aryl group. The method is especially suited for the extraction of gold using ion flotation.
