...center. Tubes of sample blood go to the laboratory for high-speed analysis and typing. Centrifuges separate out various blood components; the red cells, with glycerol added to prevent ice-crystal formation, are flash-frozen in liquid nitrogen at -320° F. Stored at this same temperature in thin stainless-steel flasks, they will keep for years. Says the center's Biochemist Arthur W. Rowe, who developed the technique: "We have taken a long step toward ending the tyranny of the 21 days...
While the hatch problem was being solved, NASA and North American Aviation engineers went to work on combustible materials that had cluttered Apollo's spacecraft before the January fire. Aluminum plumbing which melted at 1080° F. has been replaced by stainless steel. Brazed joints that withstand temperatures approaching 1,600° F. have been substituted for soldered joints that melt at 360° F. Coolant pipelines, which service electronic components and can release flammable glycol when ruptured, have been "armor-plated" at joints with high-strength epoxy. Should the joints come open, the epoxy serves as a back...
Indefatigable? Oddly enough, producing Zackay and Parker's super steel involves no other ingredients than those already used in steel alloys. "It is a new combination of alloys normally used in various kinds of stainless steel," says Zackay. Once the two professors hit upon the basic composition, "the only variation from the production of ordinary stainless was a deformation of the steel at temperatures from 500° to 1,100° Fahrenheit," said Parker...
...worth of sculpture to fill the central promenades and the Canadian and theme pavilions; Canadian industry kicked in with another $1,500,000 worth of commissions for more than 15 sculptors. All are Canadians except for the U.S.'s Alexander Calder, whose gigantic $200,000 stainless steel Man on the International Nickel Co. plaza greets Expo visitors as they get off the metro at the Place des Nations...
...days, when you walked into a drugstore and bought a hand-dipped product, are gone forever." Today, packaged ice-cream accounts for 72% of the 800 million gallons sold annually in the U.S. To win that market, Maryland Cup developed the Flex-E-Fill, a 1,200-lb. stainless steel machine capable of packaging 44 kinds of ice-cream products in different sizes at speeds of up to 200 pieces a minute. The company has "loaned" 300 Flex-E-Fills to dairies, makes its money on the containers they buy to feed the machines...
