  • Patent number: 5389275
    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.
    Type: Grant

  • Patent number: 5037571
    Abstract: Sodium hydroxide-water solutions that have freezing-melting point plateaus below 46.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.

  • Patent number: 4872557
    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.
