Flash-Dater. Finding the age of ancient objects by radioactive Carbon 14 depends on supersensitive measuring apparatus. Professor Willard F. Libby, University of Chicago discoverer of Carbon 14 dating, uses a Geiger counter surrounded by a shield and other protections against intruding radiation. Chicago's Professor James R. Arnold announced last week an even more sensitive system...
...sample containing Carbon 14 (perhaps from a Sumerian tomb) is dissolved in a hydrocarbon fluid in a 4-in. tube. Radiation from its unstable atoms makes the liquid give flashes of light. They are too faint for human eyes to see, but photomultiplier tubes pick them up. The whole system is immersed in liquid mercury. As a further safeguard, the counting apparatus is adjusted so that it ignores all flashes of light too weak or too strong to come from Carbon...
Carbonless Copies. A treated paper for making multiple copies of business forms without using carbon inserts has been developed by National Cash Register...
Roberts believes that the cylinder had been broken by a student who had tampered with it. Since all the old soda and acid type extinguishers had been replaced recently with new carbon dioxide ones, the students were unfamiliar with them, and were probably too excited to read the instructions printed on them, he added...
