Wilmot H McCutchen: Rotary vacuum distillation and desalination apparatus. July 9, 1996: US05534118 (37 worldwide citation)

A controlled bubble of cavitation is formed within the distilland by opposed centrifugal and centripetal forces in the plane of an afferent mesial passage. Thus a distilland surface forms around the axis of rotation, and saturated vapor is continuously stripped from this distilland surface by the wo ...

Michel S M Lefebvre: Method of performing osmetic distillation. Limitinstant, Hale and Dorr, November 1, 1988: US04781837 (35 worldwide citation)

A hydrophobic semi-permeable membrane process (e.g., using hydrophobic microporous hollow fibers) for the concentration of a dilute solution of low osmotic pressure by osmotic distillation (also known as membrane distillation or membrane evaporation), which is a separation process using as its drivi ...

Richard M Goodman: Process for magnesium scale control using mixtures of polycationic and polyanionic polymers. American Cyanamid Company, William J VAN Loo, August 28, 1979: US04166041 (35 worldwide citation)

Magnesium hydroxide scale formation in evaporative desalination units is inhibited by adding to the saline water being processed a mixture of certain polycationic polymers and polyanionic polymers derived from an ethylenically unsaturated dibasic acid or an ethylenically unsaturated sulfonic acid.

Joseph Yaeli: Method and apparatus for processing liquid solutions of suspensions particularly useful in the desalination of saline water. Benjamin J Barish, March 24, 1992: US05098575 (35 worldwide citation)

A method and apparatus for reducing the concentration of a first substance in a first liquid by: (a) subjecting the first liquid to natural osmosis, via a first semipermeable body, with respect to an intermediate liquid, which intermediate liquid is a solution or suspension of a second substance in ...

Enis Ben M, Lieberman Paul: An improved method of transporting and storing wind generated energy using a pipeline. Enis Ben M, Lieberman Paul, SHIMAZAKI J John, August 9, 2007: WO/2007/089872 (35 worldwide citation)

Wind turbine based power generation and storage system network and method wherein potential energy is stored as compressed air. A high-pressure pneumatic pipeline system is employed to link remote wind farms. The pipelines are located on the desert floor and adjacent railroad beds. The compressed ai ...
