...World War I, the only large-scale commercial method of producing toluene was from by-product coke ovens, which were then a bright new technological improvement over beehive ovens. Germany's Heinrich Koppers, at the instigation of U.S. Steel, had begun revolutionizing U.S. coke production with his ovens in the early 1900s. War and the Alien Property Custodian dumped his properties into U.S. hands (chiefly the Mellons') and also accounted for the growth of Koppers Co., which by war's end was putting a new U.S. coke oven into operation every 60 days, a new U.S. toluene...
...many other fields, petroleum technology has suddenly eclipsed coal technology as a source of toluene. The oil industry is already handling the bulk of U.S. toluene production. The toluene capacity of by-product coke ovens now accounts for only about one-third of total production; the rest will come from two complicated (and increasingly hush-hush) petroleum processes...
...order was designed to relieve not only a looming smokeless powder shortage, but the sugar scare (see p. 70). Most ethyl alcohol is normally made from molasses, a by-product of sugar. To increase their production, however, the regular alcohol makers have recently been using not just blackstrap molasses but whole cane syrup (high-test molasses), thus cutting into the sugar supply...
...gold miners are still busy, but their work is due to taper off. Less than 15% of U.S. gold is mined as a by-product with lead, zinc and other base metals. All U.S. gold mines have had hard sledding on priority ratings for new equipment, and last September, when 0PM gave all U.S. mining operations an A-8 priority for repairs, placer mines (which mine about a third of U.S. gold) were specifically excluded. If U.S. gold mines must suffer for lack of equipment, it is natural that British Empire mines should suffer...
...inventor, Engineer Frederick Kurt Kirsten of the University of Washington. "Up to now it has had to be ground-a laborious process-and much of it came from Norway and Sweden." Within a few weeks, a plywood factory in Portland, Ore. sold several carloads of wood dust, a profitable by-product of purifying...
