Bombshell Mikes Make Permanent Record of Conference
WITH the aid of a new electrical system making use of a battery of bomb-shaped microphones and a switch board, the recording of minute but important details of lengthy conferences is now simplified to a considerable extent. In addition, greater accuracy in the transcription is obtainable.
THIS is the day of the artist. His skill is sought wherever design and color are important factors in the sale of merchandise. Furniture, rugs, wall hangings, household utensils, wearing apparel, jewelry, art gifts, lamps, automobiles — nearly everything sold today depends, on design and color to attract the eye of the purchaser. Drawings for advertisements in newspapers, magazines, catalogs, folders, posters, display cards and many other media call for the skill of the modern artist. Consider the number of drawings in this magazine alone! Art is a necessity in modern business.
New Building Construction
The introduction and use of metal and glass as construction material has been hailed as the greatest forward step in architecture since the introduction of steel frame buildings. The lighting features illustrated on this page are but one of the many advantageous features of this new combination. Buildings can be put up in one-half the time and at a 20% saving in cost from the ordinary masonry.
Synchronizing Photo Flash Lamp With a Camera Shutter
THE difficulty of synchronizing the flare of a photo flash lamp with the click of the shutter is frequently encountered by enthusiasts of the camera art. There's a way to overcome this difficulty, however, and that is by constructing the little gadget shown in the accompanying photo. The contrivance consists of a flat type pocket flashlight battery mounted between two pieces of wood, on the top of which is affixed a common porcelain socket to hold the photo flash lamp.

"Boat Tunnel" for Harbor Crossing
PROPOSED as a substitute for the suggested Golden Gate suspension bridge at San Francisco is an ingenious boat tunnel of unique design which, it is claimed, can be built for one-third the estimated $35,000,000 cost of a suspension bridge. This and other advantages of the design have led authorities to consider seriously the erection of the boat tunnel bridge, which would be the only one of its kind in the world. It was conceived by Cleve F. Shaffer of San Francisco.
Putting Nature's Power to Work
Methods of Harnessing Natural Energy Described by DICK COLE Upward of 40,000 inventions a year are granted patents by Uncle Sam, but not one of these offers a practical solution of the problem which scientists agree is the most pressing of them all— that is, how to harness natural sources of energy for power. Mr. Cole does not profess to have solved the problem, but the methods he describes here point out the trend of probable development. WHAT is the most needed invention? Not television—not new kinds of airplanes—not speedier automobiles. Men of science are agreed that what the world needs most is a motor which converts the sun's rays and other forms of natural energy into usable power. Orville Wright, Lee De Forest, Elihu Thomson, and other leading scientists are among those who proclaim the need for a new motor.
Steam Will Power Tomorrow's Planes!
The oldest prime mover—steam—is staging a comeback. Read what amazingly logical things can be accomplished with new designs in planes through the use of steam as a power plant and control medium. by EARL D. HILBURN Aeronautical Engineer EVERY once in a while we have to "get back to nature"—get back to the simple things our dads used. Often we find that we've been on an engineering merry-go-round and that the old gentlemen who were our forbears had some right good ideas in design, but were unable to use them to the fullest extent of their theories because the right materials were not available in iron, or steel, or something else. And every so often the subject of what tomorrow's airplane will look like bobs up in some writer's mind. He is usually hard pressed to get something really new to write about, so he lays it on thick and the resulting pipe dream generally makes an air-minded man who has any air "savvy" pretty sick.
