...Cambridge, E. Leon Chaffee, Gordon McKay Professor of Physics and Communication Engineering, announced the solution of the hitherto baffling mathematical problems presented by power vacuum tubes. The discovery climaxed ten years of research...
...distilling vessel is pumped out leaving such a high vacuum that practically none is left, molecules flying off a hot distillate have "free paths"-that is, they are not interfered with in their flight. The free paths of molecules differ with their weight. Hence, by adjusting the distance between the hot surface of the distillate and a cold condensing surface, molecules can be separated by weight. "Dr. K. Hickman," said Dr. K. Hickman last week, ''began experiments in high-vacuum distillation in 1927. In 1931 he constructed the continuous molecular still and was able to separate from...
...Hickman still, the hot surface carrying the distillate and the cold condensing surface are in the form of concentric, vertical cylinders. The vacuum is about one-millionth of atmospheric pressure. General Mills joined Eastman Kodak in erecting a pilot plant, which was put into semi-commercial operation a year ago. Its Vitamin A capacity is 60 billion units a week. This output is expected to be trebled by two stills of improved design now under construction...
...spiritual exhaustion" of nations. "It is emotional fatigue which causes a people to abdicate in favor of supreme commissars or a reichsfuchrer or il duce. When the spiritual forces making for democracy are at a low ebb and the material conditions upon which mere existence depends are adverse, a vacuum is created into which a dictator may easily enter...
