...apparatus applies two metal electrodes to the chest, near the heart. The operator of the machine then adjusts the current to set the heart beat at the desired rate...
...powerful 15-kw. station will be built near Camden, N.Y. Its three 625-ft. transmitting towers will send out low-frequency signals over 2,500 to 3,000 miles. Friendly (and enemy) aircraft from the Azores to Seattle will be able to take a radio bearing into their electronic apparatus, measure their distance from Camden by comparing signals from the three antennas, and pinpoint their positions within ten miles. When a pilot gets close to his destination, he will switch from Navarho's beam to a short-range station, follow it in to the airfield...
appreciable amount of its energy is reflected downward and can be picked up by sensitive apparatus as much as 200 miles away from the transmitter...
Faint Shadows. In an ordinary TV setup this signal would be far too weak to be turned back into an image on the face of the picture tube, but Morgan and Sturm have learned how to amplify it enormously. They can put their apparatus to work watching a fluoroscope in a darkened room; it can see in light ten times too dim for human eyes. The faint shadows may be barely visible, but when they appear on the picture tube, they are bright enough to be studied in full daylight. This is important for doctors who examine patients by fluoroscope...

Last fortnight he set up his apparatus on the ice of Lake Kegonsa, a safe distance from Madison. The spindle and hub were attached to a steel barrel frozen into the ice and guyed solidly. A double strand of woven nylon, 400 ft. long, led to a quick-release fixture under a wing of the airplane...
