...watt ultrashort-wave transmitter could weigh less than 50 lbs., said Dr. Hutcheson, and its signal would be strong enough to reach from moon to earth, even without the advantage of a directional beam. Power could come from batteries. The whole apparatus would have to be designed to deal with the vacuum of space, and designed to operate both in extreme cold and in the high temperature (250° F.) of the lunar midday. To Dr. Hutcheson such difficulties were minor...
Scientists are working hard to find some light-weight shield to replace the masses of lead, concrete or water they use at present around their "bad-acting" apparatus. A composite shield may prove useful; but it too will be massive and costly. No "magic shield" is in sight...
...British businessman has also . . . found ways and means of removing the stick from his back. The growth of trade associations, of price-fixing and market-sharing devices-the whole apparatus of protection, in fact-is inspired by nothing so much as by the desire to prevent the bankruptcy of the inefficient-even if, thereby, the progress of the efficient is also impeded. . . . In a competitive economy, such as the American, when one firm acquires a more efficient machine and cuts prices, all others are compelled to follow suit, whether they can "afford...
...students, Emily Griffith would perhaps have been proudest of a 26-year-old veteran, racing against approaching blindness. Opportunity had set up special training apparatus for him to study electricity, using bells instead of lights as signals. He planned to open his own electrical repair shop in Pueblo, when the night closed...
Sphere & Float. The pressure-resisting part of the submarine will be a 15-ton steel sphere nearly 7 feet in diameter, with walls 3½ inches thick. By itself, packed with apparatus and Professor Piccard, it would sink like a stone forever. But immediately above the sphere will be a submerged, boat-shaped float filled with light buoyant oil, which cannot be squashed. Below it, held tight by powerful electromagnets, will be enough iron ballast to make the submarine sink. When the Professor shuts off the current from a one-ton battery, the electromagnets will drop the ballast...
