Adams' battery consisted of a lightweight container, one electrode made of magnesium and another of cuprous chloride. It could be stored indefinitely and activated by simply pouring in fresh or salt water. While cooking up some cuprous chloride on his wife's stove, Adams accidentally dropped cigarette ashes into the brew-and vastly improved it. Moreover, when his battery was connected to a load, a chemical reaction took place that produced heat. As a result, the battery worked surprisingly well at temperatures...
...people of John Cheever's stories dwell among the shifting symbols of success, where the status is very seldom quo. Most of them live in Manhattan or commute to its skyscraper hives, for that is where the honey is. But somehow their lives, loves and labors leave the cuprous taste of pennies in their mouths; the middle-income bracket is their social vise. Few writers have probed the masked anxieties of the "have-not-enoughs" with the skill and authority of John (The Wapshot Chronicle) Cheever, 46. After Marquand, he is the ablest chronicler of the interior life...
...making it clumsy to handle. Normally a ship must have her hull scraped every six to 18 months. But the new paint, developed by the Navy's Bureau of Ships, keeps a ship's bottom whistle-clean for two to five years. A brown, syrupy compound of cuprous oxide and synthetic resins, it is sprayed on hot (300°F.), forms a coat ten times as thick as ordinary paint...
...duplicate its composition. The synthetic rubber which grew out of the Nieuwland researches is 40% chlorine, not an ingredient of natural rubber at all. At a chemistry symposium in Rochester, during the winter of 1925, Father Nieuwland read a paper on the formation of divinyl acetylene from acetylene and cuprous ammonium chloride. Du Font's Dr. Elmer K. Bolton was there, suspected that if the monovinyl could be similarly produced, artificial rubber was at hand. Acetylene, from common coke and lime, is cheap...
