...Research (which has no counterpart in the U.S.) prepared L, phenol-formaldehyde resin which was more useful for its chemical properties than as a plastic. When immersed in "hard" water, which contains salts of calcium, it entered an exchange: it took calcium atoms from the water, replaced them with sodium, thus softened the water...
This was not new, for natural "green-sands" and artificial zeolites have long been used for such softening. But a slightly more complex resin of the same type proved able to draw even sodium atoms out of solution, replace them with hydrogen. This merely substituted acid for salt, but still another resin, made with amines instead of phenol, extracted the acid intact, leaving pure water. Both resins were gradually used up but could be revived by reverse treatment with stronger solutions...
...last the truth came out. The kitchen helper seeking the powdered milk had dim-wittedly come back from the wrong storeroom with seven pounds of sodium fluoride roach powder, with which hurried, overworked Cook McKillop had scrambled the eggs. At week's end McKillop and his boss, Mary O'Hare, were booked on charges of involuntary manslaughter...
...great fire of 1666, for example, was touched off by the countless fires which townsmen lit to purge the air of plague. Use of chemical sprays to control air contamination was first attempted in 1928 by three doctors who tried a fine mist of sea water containing sodium hypochlorite. This venture gave promising results, but all such research lapsed for another decade. Within the last few years, several research groups (notably the University of Pennsylvania's new Air-Borne Disease Laboratories) again began testing various sprays. Many chemicals were found to kill airborne micro-organisms quickly, even in concentrations...
Knuckle-Swinger Up. Last week the Navy fixed responsibility. Vice Admiral Robert L. Ghormley was relieved of his command of the entire operation. In his place, as Commander of the South Pacific, Vice Admiral William F. Halsey Jr. went to work. Admiral Halsey, who looks saltier than sodium chloride, is known throughout the Navy as a tough, aggressive, restless man. He led the brilliant attack on the Marshall Islands in January, commanded other hit-&-run raids...
