Abstract: Desalination apparatus utilizing solar heating of metal member(s) such as balls, rollers, or metal endless belt(s) in a heating chamber and vaporizing saline water with the latent heat in said metal member(s) by spraying saline water thereon in a vaporizing chamber, a water-cooled condenser to condense the vapors, a trough to collect the condensate, a rinse tank to remove salt deposits and/or saline water from the metal member(s), and means for returning the rinsed metal member(s) for solar reheating.

Abstract: An arrangement for multistage vacuum and molecular distilling with a wiped off film using a single evaporator body common for different vacuum stages, with rotating vacuum seals between adjacent vacuum stages provided with a common drive.

Abstract: An apparatus and method for purifying a liquid by vacuum-induced vaporization of the impure liquid into a vapor in a first enclosure and subsequent pressure-induced condensation of the vapor into a relatively pure liquid in a second enclosure. A conduit interconnecting the two enclosures includes a pressure-sensitive one-way valve for permitting automatic pressure-induced vapor flow from the first enclosure to the second enclosure while preventing vapor flow in the opposite or return direction. In a first embodiment, the alternating pressure variation necessary to produce the vaporization in the first enclosure, the vapor flow through the conduit and the condensation in the second enclosure is produced by exposing the interiors of the two enclosures to the undulating motion of the surface of an open body of wave-active liquid. In a second embodiment, the alternating pressure variations are produced by mechanical means.

Abstract: An apparatus for efficiently disposing of combustible organic waste materials, such as organic industrial and household wastes, comprising a macerator and an evaporation unit where liquids are removed from the waste to leave a concentrated organic residue. Evaporation of liquids from the waste is accomplished by heat exchange with a medium heated, in part, by exhaust gases from an internal combustion engine, and in part by incineration of the solid, relatively dry organic residue. The liquids from the evaporation unit are preferably condensed to a suitable liquid form for subsequent use, and the concentrate remaining after liquid evaporation is introduced to a high temperature zone developed in the course of the operation of an internal combustion engine, so that the solid organic residue is incinerated to a relatively small quantity of ash and innocuous gases. Heat for the purpose of partially heating the heat exchange medium used in the evaporation unit is developed in the course of such incineration.
