MODELS FOR MILLIONS
It takes superb skill and endless work to produce those plastic scale model kits anyone can assemble.
LEWIS H. GLASER, founder and president of Revell, Inc., the plastic model kit company, has on file a letter received from the Department of the Navy in Washington. “The Revell ship models I have seen all possess a sailor’s concern for nautical detail as well as an engineer’s attention to workmanship and design,” the letter states.
How Ingenious Sound Producing Devices Fool Radio Microphone
You can’t always believe what you hear over the radio—the picture above proves it. Sound producing machinery of a large chain broadcasting company is shown. Thirty-three separate sound effects arc produced by the cabinet before which the operator is sitting, but in addition to this a large number of individual devices are employed, including numerous bells of various tones, a cigar box with a pulley and piece of string to simulate the sound of a curtain being drawn in a theater, oar locks used in acts calling for a rowboat, and a pillow to be struck with slats to produce the thudding effect of a prize fight blow against human flesh.
Go Dig Yourself a Fortune
Mi’s prospecting expert gives you the lowdown on what to do when you make a lucky strike.
By Harry Kursh
THE last few years have seen the emergence of a new kind of lone adventurer in America, a type that is gradually replacing the old-time prospector with his whiskers, battered hat, pickax and pack burro. The new type is the sparetime prospector, an amateur geologist and enthusiastic “rock hound” who devotes vacations, weekends and every hour he can spare from his regular activities to searching for uranium and precious metals. Naturally, friends and neighbors think he’s a little off his rocker—until he strikes it rich and retires to Florida.
How a Fraud Detective Works
By MARY K. PIRIE
WITH a girl perched on his brawny shoulders, the boy in the red swim trunks cavorted in the swimming pool. When the girl lost her hold on his wet back and started to slip, he reached up strong young arms and caught her.
While both squealed with delight, the boy thought how good it felt to be out having fun again. Ever since he’d faked that accident at the plant last month and claimed a serious back injury, Dad had made him stay home and wear a brace. “Unless you do, we’ll never get that $50,000 for ‘total and permanent disability’ we’re suing for,” the older man had warned.
How to Have A Million-Dollar Idea
Brainstorming is the new, exciting system that turns your wildest ideas into profits.
By Ardis and Kay Smith
THE meeting of the engineering staff of the National Biscuit Co. in Buffalo began on a sour note. For the umpteenth time a coal crane fuse had blown on the company’s Lake Erie loading dock, leaving the operator stranded on his perch above a 900-ton mountain of fuel, a long way from the fuse box. The usual din of machinery drowned out the distress signals he sounded on a klaxon.
Back of the Scenes at the Sideshow
By King Deckert
If you have ever attended a sideshow— and who hasn’t?—you have looked at astonishing exhibitions and seemingly impossible feats and have wondered, “how do they do it?” King Deckert, an old-time trouper, explains in this fascinating article how the public is bunked.
IN DARKEST Africa, the Voodoo witch doctor charges an admission and lets superstitious blacks view his weird collection of miracles; in more progressive countries, intelligent people pay their thin dimes every year to see “The Half Lady,” “The Human Mermaid,” “Oregon John,” and scores of other “strange, strange people,” who migrate from state to state during the summer months under the flamboyant banners of the sideshow.
HOW TO BUILD A GEIGER-MUELLER URANIUM SURVEY METER
By F. L. Brittin, S.M.,I.R.E.
ANYONE can build and operate this simplified Geiger-Mueller survey meter, which is an instrument for detecting the presence of radiations emanating from radioactive substances such as valuable uranium and radium. Specifically, the Geiger-Mueller tube, which is the most important component of the instrument, detects X-rays, cosmic rays and gamma rays. Beta rays can also be detected by Geiger tubes with very thin cathode walls.
Table Tricks with Knives & Forks
By SAM BROWN
The after-dinner tricks with knives and forks described here by Mr. Brown can be performed with little advance preparation, and they afford sure-fire entertainment for everybody.
NOTHING so very magical about knives and forks. Once upon a time there was a man who ate peas . . . But that’s something else again.
How’s this: The performer exhibits a napkin. He rolls it up loosely. He pokes a fork down into the center of the rolled up napkin. And then . . . abracadabra . . . the fork slowly rises from the napkin, bowing quaintly to the bewildered spectators.
Robot Production Line Makes 3 Radios a Minute
THE so-called “printed” radio sets are still new on the American scene, but they are rapidly becoming common items in England. A new factory near London is using a robot machine (above) which takes the plastic molding in one end and delivers the printed circuits from the other end at the rate of three a minute. It would take about 2,000 workers to do the same job by hand.
How Power Impulses Keep Electric Clocks Accurate
WHY does an electric clock keep perfect time? Some of the so-called electric timekeepers are nothing but standard spring-driven clocks, equipped with an electric motor and a device to turn on the current at regular intervals and wind the spring. But others have no spring, no clock works, in the usual sense, and do not, as a matter of fact, either measure or keep time, yet they are always accurate.
