...contrast, the U.S. space program was not faring so well. After almost two months of intensive investigation into the oxygen-tank explosion during the aborted Apollo 13 moon flight, NASA's high-level review board confirmed that the accident was probably caused by an arcing short that ignited Teflon insulation on wiring in the tank. The fire in turn damaged the seal at the top of the tank and generated heat that expanded the oxygen. The resulting pressure caused the weakened area to burst. The board also detailed an extraordinary sequence of bungling uncovered...
...After six weeks of investigation, NASA's high-level review board proposed an explanation for the explosion of Apollo 13's oxygen tank. The blast was apparently caused by the failure of two thumbnail-sized automatic switches that are designed to shut off the oxygen tank's internal heater if its temperature rises above 80° F. Tests showed that the temperature, if unchecked, could soar as high as 1,000° and cause the electrical insulating material to flake off. The arcing that results can ignite the insulation. Heat from the fire expands the compressed semiliquid...
...past few decades, they have been forced to change their minds. Besides confirming the presence of hydrogen and other earthly elements with optical and radio telescopes, astronomers have lately discovered a number of complex molecules in interstellar space: water, ammonia, formaldehyde and pairs of hydrogen and oxygen atoms that are ingredients of many other chemical combinations. Now the list has been further expanded. Researchers at the Bell Telephone Labs have detected large quantities of carbon monoxide in vast clouds of gas and dust in the Milky...
...then the 500 mile race itself. For qualifications, the cars are set up to run around a two-and-a-half mile rectangular track as fast as they possibly can. Chassis are set up for optimum handling with a small fuel load and no regard for tire wear. Oxygen-bearing nitromethane is added in large quantities to the alcohol fuel, producing increased power and decreased engine life. No car could hope to finish the race in this condition, and after a car has qualified, the crew reworks the chassis to provide a good compromise of tire wear and handling with...
Hospitals that once had horrendous difficulties in washing and sterilizing mountains of linen and equipment now have that problem largely solved. They use disposable supplies, which reduce the risk of infections spreading within the hospital: presterilized bed pads, sheets, pillowcases, blanket covers, examination gowns, surgical masks and drapes, oxygen canopies, water carafes, dishes and drinking cups, transfusion tubing and fittings, thermometers, and perhaps most important of all, hypodermic syringes and needles. But the hospitals, as well as doctors in their private offices, are finding that they have replaced one problem with another: how to dispose of the disposables...
