Nonarticular Rheumatism. A grab-bag category. Includes bursitis (inflammation of the sac that helps reduce friction around a joint), myositis (inflammation of muscle tissues), fibrositis (muscle inflammation extending to connective tissues), tenosynovitis (inflammation of a tendon sheath), and such oddities as psychogenic rheumatism. Treatment: aspirin, possibly combined with hormones such as cortisone, prednisone and prednisolone. Codeine helps kill the pain, and heat is helpful. In bursitis, surgery is sometimes used to scrape calcified deposits from the inside of a bursa. In psychogenic rheumatism no physical cause can be found for the patient's undeniable physical ills. Symptoms most often...
...friction-heated cockpit of a high-speed airplane has to be cooled elaborately to keep the pilot alive. If the pilot is taken out, and the craft becomes an unmanned missile, its interior must still be cooled to keep its electronic brain from dying of heat prostration. So, decided General Electric Co., heatproof electronic components should prove useful in the missile business. This week, after years of work, it showed whole electronic assemblies working efficiently, though red-hot in a glowing electric furnace...
Heat-resistant electronics will be most useful at first in guided missiles, where heat is generated both internally and by air friction. In many cases, they will eliminate heavy and complicated cooling apparatus. When nuclear airplanes come into the picture, the new electronics will brave heat and radiation close to the power reactors. Only the crew will have to be cooled and shielded...
...says the Navy, and is finished on the final, payoff stage that will push the moon into its orbit. Engines for all three stages have roared through ground tests. Engineers are confident that they will lick one bugaboo: heat damage to the nose of the rocket caused by aerodynamic friction...
...moon may rise to 1.500 miles in height at the far end of its elliptical orbit, travel at 1,900 m.p.h. As the moon slows in speed, it will dip closer and closer to the earth's atmosphere until, inevitably, it will disappear in a flash of friction...
