...Temporary National Economic (Monopoly) Committee, which fortnight ago was entertained by SEC Chairman William O. Douglas' smart display of the insurance industry's enormous power, last week heard Bill Douglas try to prove that insurance directors use their influence to swing business their own way. Evidence: 1) while a director of New York Life, Alfred E. Smith solicited fuel oil contracts for certain of its properties; 2) Mutual Life's deposit at Bankers Trust Co. jumped from $150,000 to $1,500,000 when Bankers Trust's President S.

...theory was worked out mathematically by Dr. Hans Albrecht Bethe of Cornell, a brilliant analyst of atomic behavior. Dr. Bethe sat down to figure out what atomic reactions would occur often enough to be important in the sun's energy economy, yet not so often as to use up the supply of some important ingredient in a hurry. He found that, at temperatures above 15,000,000° C., hydrogen atoms would attack carbon. The carbon atom would disappear for a while, but after a further series of reactions in which three more hydrogen atoms would be used...
...contacts. If it rises or falls as little as one-quarter of a decibel, the galvanometer makes contact on one side or the other, closing a circuit which starts or stops the flow of ore as the situation requires. More than 75 of these electric ears are already in use...
...Float. If a handful of bird shot mixed with sawdust is thrown into a pail of water, the shot will sink, the sawdust float. Reason: the specific gravity of water is greater than wood's, less than lead's. The flotation method of separating ores from waste, using liquids of higher specific gravity than water, has been used for nearly a century. For over three decades E. I. du Pont de Nemours & Co. has been trying to devise an economical flotation method for separating impurities such as shale and slate from low-grade anthracite coal. For "parting liquids...
...rains. He has wished that he could put the hay away wet or dry, and that he could store it in a silo the way he does corn fodder. Last week the enterprising Monsanto Chemical Co. of St. Louis told him that he could-if he would just use a new, low-cost, scientific treatment which Monsanto has trademarked as "Phosilage...
