...announcing that he had found enormous pressures in the roots of tomato plants-pressures high enough to serve tomato plants hundreds of feet tall. The trouble with previous pressure experiments, it appeared, was that they were made on dead or dying roots. At Princeton, Dr. White has an apparatus which keeps detached roots alive indefinitely by supplying them with nutrient fluid. When he attached glass tubes carrying columns of mercury to his tomato roots, the mercury went up until it indicated a pressure of more than eight atmospheres (125 Ib. per sq. in.), at which point the powerful roots broke...
...another method, Chaffee has developed apparatus by which the power tube operation can be tested at the ordinary, household, current frequency of 60 cycles, for which electrical measuring instruments are standard and extremely accurate...
...they had an apparatus which would show, on a sort of artificial horizon, every object for a mile around, together with its distance and direction, ship captains nosing uneasily ahead through a fog would be much safer and happier. So far such a mariner's boon has not appeared. Yet it seems to be on the way, because the problem is simply one of technical ingenuity in applying principles already understood...
Last week the talk among communication engineers was of a new fog-eye which, instead of simply signaling, obtains a picture like the Williams device but does so immediately. Patented by Clarence W. Hansell of Rocky Point, N. Y. and assigned to Radio Corp. of America, the apparatus emits radio waves so short that some of them bounce back from an obstacle to the sending point, where they are focused so as to create a tiny image on a copper sulfate screen.* The picture emerges as a white silhouette on a blue background. If the obstacle is a ship...
Sunday before last Fox Movietone Cameraman Eric Mayell and Universal Newsreel's Norman Alley, lugging their cumbersome apparatus, struggled down to Nanking's shell-smashed Bund and frantically waved at a gunboat which was headed upriver. The Chinese were fleeing Nanking and Mayell and Alley did not plan to remain with a handful of their colleagues to witness the triumphal Japanese entry. The departing gunboat put off a motor sampan, which returned to pick them up. Thankful for their rescue and still a little worried for the safety of their friends they left behind, Mayell and Alley were...
