From Lockett on, the Giannini cover procedure is pretty complicated. To try to simplify it, I asked one of our artists to draw the diagram you see. What it means is that in order to give one of our National Affairs writers, Paul O'Neil, all the information he needed we called on our Los Angeles, San Francisco and Washington bureaus to interview the people who could supply it, put our researchers here in Manhattan to work culling the material we already had in our morgue and supplementing it with local interviews...
Loran shore stations always work in pairs: the "master" and the "slave" (see diagram). Both operate on the same frequency and both broadcast the same radio "pulse signals"-short bursts of radio energy transmitted at regular intervals. The pulse from the master station appears as a "pip" on the "scope" of the plane's loran receiver. It also sets off a second pulse from the slave station, which is received as a second pip. The pulses arrive at slightly different times, since they have traveled different distances...
...diagram above, P.T.M. is sending 24 telephone conversations. The trick is done by allowing each conversation only part-time on the air. A cathode-ray tube acts as a multiple switch. Inside it, a scanning ray revolves like a clock hand, 8,000 times per second. Arranged like the numbers of the clock are 24 contacts, each connected with a different telephone. As the ray sweeps over a contact, it puts on the air a minuscule snatch of the voice passing through the telephone with which the contact is connected. When it moves to the next contact, the next telephone...
...This diagram merely illustrates the principle on which the atomic bomb works, not the specific processes occurring in the bombs dropped on Japan. Actually, there is no need for a reaction multiplying as fast as that shown above. An increase of a few percent of neutrons in each cycle is enough to do the trick...
...best observed in history. The moon's shadow, falling on the earth at 6:14 a.m. at Cascade, Idaho, raced at 47 miles a minute across Montana, Canada, Greenland, Norway, Sweden, Finland and Russia, disappearing after just two hours and 27 minutes at Tashkent, in Turkestan (see diagram). The total eclipse followed a very narrow path (maximum width: 58 miles, in Greenland), but it covered a long stretch of land area. One of the most elaborately equipped expeditions (a Harvard-led group at Bredenbury, Sask.) missed it completely because of clouds, but scores of other astronomers' parties...
