...evolutionary stage, says Dr. Mayerson. It is found only in higher animals; the higher the animal, the more complex the system. The complexity is necessary, says Dr. Mayerson, because in the mammal, nature evolved a closed, high-pressure blood-circulating system with conduits of diminishing thickness carrying blood and oxygen to thin-walled capillaries. "But here, nature ran into a snag: the high pressure made the capillaries leaky." Even the large molecules of proteins slip through delicate capillaries. Nature had to invent a collection and drainage system so that whatever Leaked into the tissue spaces around the capillaries could...
...though MHD generators may be simple in principle, they are devilish devices to design, mostly because of the extremely high temperature that must be reached to ionize their gas and make it conductive. Avco does the job by preheating the incoming air that eventually becomes plasma, adding extra oxygen to it, and burning oil with it in a chamber that looks like a rocket engine. This produces a flame with a temperature of 5,300° F. Spiked with a little powdered potassium carbonate to increase the ionization, the flaming stream of gas shoots between the poles of a magnet...
...hills of Wales, Queen Elizabeth II last week pushed a button and put to work Britain's newest steel mill-the Spencer plant of the government-owned Richard Thomas & Baldwins company. The new plant is designed to produce high-quality steel by means of the fast-spreading LD oxygen process (see below). And it has one other remarkable attribute: it almost runs by computer. From receipt of customers' orders to the final finishing of bars, its operations will be scheduled and supervised by a unique corps of machinery designed by Britain's Elliott-Automation...
...oxygen furnaces at the Richard Thomas & Baldwins mill are the newest weapon that steelmen around the world are wielding to compete with cement, aluminum and plastics. Pure oxygen, when blown into steel crucibles, enables them to make steel faster and cheaper than ever before. Last August, boldly investing in the future despite poor current business, U.S. Steel Corp. announced that it will build two iso-ton "basic oxygen" furnaces at its Duquesne works. Last month. National Steel Corp. opened two 300-tonners at its Great Lakes works. In all, LD fur naces are now pouring steel in 17 nations from...
...began seeking a way to make steel with less scrap-of which Austria has little. Joined by experts from another nationalized steel company, the Alpine Montan works of Donawitz, they derived the LD process from the principle, discovered a century ago by Sir Henry Bessemer, that pure oxygen speeds the cooking of iron, coke and limestone into steel...
