Scientific Novelties
Peacetime Tank for Swamps
• The machine at the left was built by a member of a distinguished engineering family with the idea of using it for relief in case of hurricanes or floods in the Florida Everglades.
Telescope—Anti-Aircraft
• THE machine below shoots at balloons, but it is a camera, 16 feet long, and the longest outside astronomical observatories. It was used as another check on altitude flight.
“Seeing” Heat and Cold• THE inventor of the “radio sextant” (by which it is possible to measure the height of the sun on a cloudy day) now uses a similar principle to detect the presence of unseen objects whose temperature is different from their surroundings. The apparatus, as shown above, indicates the long-wave (infra red or heating) radiation received from any given point.
Out of the Shell—an Exploring Expedition
• THE stratosphere balloonists had nothing at all on the inquiring young hen pheasant whose advent into the outer world was caught by a patient photographer, as shown in the unique pictures below.
Fingerprint Magnifier
• THE projector below was built especially to measure fingerprints for identification purposes.
Dazzle-Proof Glasses
• BY moving the head, one protects the eyes against headlights.
