Abstract: Sodium hydroxide-water solutions that have freezing-melting point plateaus below 47.degree. F. can be used to store cooling capacity by their heat of fusion, and-compositions that freeze at about 41.degree. F. are suitable, particularly when nucleating agents such as sodium dichromate and dispersing agents such as a clay, are also used.

Abstract: A nestable, stackable container is formed from a container body having a forward portion with a convex surface adapted to mate with the concave surface of the rearward portion of the next adjacent container. The container also has rasied male die parts on its top wall adapted to mate with indented, female die parts on the bottom wall of an upwardly adjacent container.
Abstract: The combination of a cooling tower and a tank containing packaged, eutectoid salt compositions. The tower provides cooled water to freeze the salt compositions, which are later used to chill water for air-conditioning a building.
Abstract: A eutectoid salt hydrate composition (phase change material) utilized for the storage of thermal energy at a temperature less than 50.degree. F., in which the optimal mole ratio of potassium chloride to sodium sulfate to ammonium chloride is 1:4:4.
