Abstract: ABSTRACT OF THE DISCLOSURE           Disclosed is an improved method of concentrating an aqueous solution containing a first salt and a second salt, the solubility of the first salt increasing more greatly with increasing temperatures than the solubility of the second salt, by multiple effect evaporation, wherein the flat evaporator effect is the hottest, mother liquor effluent over-flow from cooler evaporator effects is forwarded to hotter evaporator effects, mother liquor effluent overflow from the first evaporator effect is forwarded to a zone maintained at atmospheric pressure and mother liquor effluent from the zone maintained at atmospheric pressure is for-warded to a first salt recovery step.  In the improved method, the first evaporator effect is operated at super atmospheric pressure and at least 4°C. above the atmospheric boiling point temperature of the mother liquor therein and flashing of mother liquor effluent overflow therefrom is reduced by mixing therewith sufficient mother liquor effluent overflow from a cooler evaporator effect to provide a resultant solution which is reduced more than 2-C. in temperature, preferably to its atmospheric boiling point temperature, and is substantially at its invariant composition at that temperature.

Abstract: FN 914,796 ABSTRACT OF THE DISCLOSURE           A fluid dispensing piston for a cylindrical dis-pensing tube has a recessed transverse end wall formed with at least one aperture.  The aperture is normally covered by a fluid seal removably retained on the exterior surface of the end wall.  The piston is placed in a cylindrical dispensing tube with the exterior of the end wall pressing against the fluid in the tube and the piston is moved axially down the tube to dispense the fluid.  Further fluid may then be added to the tube and a second piston moved axially down the tube to dispense that fluid, the conformable material covering the aperture in the end wall of the first piston being forced away from the end wall to uncover the apertures as the second piston is moved down the tube to create a pathway for the fluid through the first piston.

Title: Method and apparatus for constructing and maintaining  an offshore ice island
Inventor: JAHNS HANS O
IPC: E02B17/02
Filed: 1979-04-19
Granted: 1981-03-31
Abstract: ABSTRACT A method and apparatus is disclosed for forming and maintaining an offshore ice structure in an Arctic environment.  The structure is formed by a series of caissons oriented in a ring forming an enclosure capable of retaining a predetermined amount of water and thereby defining an ice island when frozen.  The structure includes a passive heat extracting system which removes heat from the water within the enclosure and from the soil immediately below the enclosure and the caissons thereby advancing the freezing of the soil beneath the enclosure and water within the enclosure. In this manner, the lateral stability of the structure is improved by providing a single frozen mass of water and soil bonded in unitary construc-tion increasing the foundational base of the structure.  In addition, refrigeration means are provided to prevent surface melting of the ice within the enclosure and preserve the integrity of the ice structure during warmer months.  The island structure can, therefore, withstand greater lateral ice loads during the winter months and greater wave loads during the summer months and also provide a dry surface from which offshore opera-tions can be conducted year-round.

Typical solubilizers are made by reacting an alkyl-substituted succinic anhydride containing about 12 to about 500 carbon atoms with an alkanol amine such as diethyl ethanol amine.  Typical surfactants are non-ionic hydrophilic surfactants such as ethoxylated phenols.          Typical functional additives are anti-wear, extreme pressure and load-carrying agents such as dithiophosphates.  The aqueous systems formed with the aid of such combinations are useful, for example, as water-based hydraulic fluids.
