...fields strange plants had sprouted to a height of seven feet.* Canny Richard Mortimer examined the flora, reported: "The plant can be grown as easily as a common weed, and raw rubber will drip from it when it is cut. Samples of the plant were sent to a chemist. The report came back: 'pure latex.' Each plant yields between one and two ounces of latex; an acre would yield over two tons. The possibilities are stupendous. The center of the rubber-producing world will be right here in England, and the cost of rubber will be only...
...discoverer is a young Selas physical chemist named John M. Walker. He has astonished engineers with some of his demonstrations: e.g., he pours a mixture of kerosene and water into a tube; the liquid comes out rapidly through the pores of two closed-end porcelain cylinders which are the outlets of the vessel; out of one comes pure water, out of the other, pure kerosene...
Projection of a Future. Selas Co. believes Chemist Walker's discovery is a fundamentally new principle of filtration, basically different from the two previously known: i.e., mechanical filters (like the sieve) and osmosis (which operates through membranes fine enough to separate molecules...
...Chemist Midgley buckled down, with a corps of able assistants, in Frigidaire's Dayton, Ohio laboratory. Compound after compound was examined, tested, cast aside. Finally Chemist Midgley hit on dichlorodifluoromethane (carbon; chlorine; water; and the mineral, fluorspar). It was nonpoisonous, odorless, would not support flame. For the second spectacular time, Midgley had rung the laboratory bell...
Crossbreeding Tells. Three years ago, however, a British chemist named A. C. Thaysen began to explore yeast's possibilities as a straight food. He developed a new strain (from a variety called Torula utilis) with a pleasant, nutty flavor, so cheap to produce (10? a lb.) that the British Government has started building a plant in Jamaica to make 2,000 tons of Thaysen's "food yeast" a year.* Chemist Thaysen at most expected to serve his yeast in concentrated doses to supplement a poor diet; despite its pleasant flavor, he did not conceive of Torula utilis...
