...process will, it is calculated, make alumina (from which aluminum is reduced) for $35 a ton against $33 by the Hall process. But the alunite process yields one-half ton of sulfate potash worth $18.12 and one-third ton sulfuric acid worth $6, as byproducts. Moreover, alunite-aluminum uses less electricity than Hall-produced aluminum. Kalunite hopes to borrow up to $16,000,000 from RFC to build two plants in Marysvale, Utah, perhaps a third in Washington's White River Valley. Both sites are near supplies of alunite ore, also not too far from titanic Grand Coulee, which...

...critical materials are in TVA mountains. To make sure that no TVA assets are overlooked, David Lilienthal keeps a staff of researchers hard at work. Last week he announced that one of them, frail M. I. T. man John Henry Walthall, had developed a new process for extracting alumina (raw material of aluminum) from common clay, which abounds in TVAland. Other TVA discoveries include methods for making a cork insulation substitute out of vermiculite (a mica-like rock), for deriving magnesium from olivine, plastics from cottonseed hulls...

...thermal cracking refiners had squeezed every drop of gasoline they could from the crude. Up went the heat to 900°. Pressure was applied. And as still men and panel men anxiously watched the gauges, the vaporized residuum was forced through the macaroni-shaped catalyst of silica and alumina. When 11-4 had done its work, yield sheets showed that the waste oil had given 7,200 barrels of gasoline. Furthermore, the gasoline had an octane (antiknock) rating of 81, compared with the octane-60 which average crudes yield under present processes...

...Count Cippico is a close friend of Arthur Davis, chairman of the board of Aluminum Co. of America. Both men are heavy smokers and some three years ago they got to discussing some means of eliminating nicotine. Mr. Davis thought of an aluminum holder with a filter of activated alumina, an absorbent much used in chemistry. This proved too expensive, but in the experiments Aluminum Co. Chemist R. B. Derr noticed that butts of the cigarets in contact with aluminum were always soggy and black with absorbed nicotine and tar. This was because tobacco is itself one of the best...

Professor Willstätter's method of segregating enzymes is beautifully simple. The enzymes are colloids. White clay (kaolin) filters absorb certain kinds of colloids, alumina filters certain other kinds. Enzymes, which pass through both alumina and clay filters, have a third set of characteristics. By shrewd use of colloidal physics and chemistry Professor Willstatter segregated the three important enzymes of pancreatic fluid-lipase which acts on fats, amylase which acts on carbohydrates, trypsin which acts on proteins...
