New Schemes for Harnessing the Winds

INVENTORS PROPOSE STRANGE PLANS TO BRING THE OLD DUTCH MILL UP TO DATE

IS THE windmill coming back? With strange, unconventional types, inventors are seeking to adapt it to a modern age. Their experiments may bring new success in man’s effort for 800 years or more to harness the wind for power.

Centuries ago, people milled their flour, sawed wood, and pumped water with the picturesque European windmills whose enormous “sails” swept from earth to sky. This country contributed the smaller and more practical narrow-bladed type that pumps water on farms today. A new miniature design shaped like an airplane propeller charges storage batteries for radios and for lighting rural homes.

Suitcase Is Emergency Crib
Unable to bring a baby’s cot aboard a war-refugee ship from the Mediterranean island of Malta, an ingenious mother converted a suitcase into a combination bed and carriage for her four-month-old son. The illustration above shows them packed for the trip, with the baby watching the view through an improvised window. A lettered sign insured careful handling of the crib.

Do Wild Radio Waves Cause Air Disasters?

Millions of horsepower of high-frequency electric energy, running “wild” in the air, may be the cause of mysterious disasters to aircraft, such as the loss of the Akron, the dirigible R-101, Knute Rockne’s airplane, and scores of others. How these amazing currents affect not only airplanes but your body, your home, and any objects that fail in tune with them, is explained in this unusual article on the unseen menace from the sky.

by BURTON MANFRED

THE radio experts of the United States Navy have recently completed a series of astounding experiments, experiments that prove far beyond the shadow of human error that there is a new menace in the sky. Hour after hour, day after day countless thousands of horsepower of high-frequency electric energy is being pumped into the air by great radio stations and other high-frequency machinery which has become a part of our civilization.

Only an infinitesimal speck of this prodigious output of energy is consumed by the radio receivers of the world. What happens to the rest? Does it become a wild and roving source of death and destruction or does it rush into the frigid voids of space never to return to the earth?

NEW LEG SHACKLE HOLDS RUNAWAY PRISONERS
A new leg shackle that automatically disables a prisoner who tries to run is being tested by the U. S, Division of Investigation. Invented by a seventy-three-year-old Louisiana farmer, it consists of two hinged steel rods, bound to the thigh and lower leg by padded chains. As a prisoner bends his knee sharply in attempting to run a ratchet mechanism in the hinge automatically locks, preventing him from again straightening the leg.

Three-Hole Paper Punch
Three correctly spaced holes can be cut at the same time in paper used for loose-leaf folders or notebooks, by means of a compact hand punch now available. Used as shown below, the punch fits easily into a briefcase or desk drawer.

Sharp reintroduced this idea last year with the Dual View, an LCD that allows two viewers to see different images depending on their viewing angle. Though frankly I think the glasses make this one look much cooler. Even the dog has a pair.

Two-Headed TV Set Displays Two Different Shows at Once

Two people can enjoy different TV programs at the same time with a new set. The experimental Du Mont Duoscopic is actually two receivers in one cabinet, with two chassis, two sets of controls and two viewing tubes mounted at right angles (inset). A semitransparent mirror superimposes the two pictures, but each viewer sees only one show by watching through polarizing spectacles. Earphones handle the sound.

SCIENTIFIC ONE-HAND TYPING

Simplified Keyboard Research Aids Handicapped Veterans

By RICHARD B. LEWIS
Lt. Comdr., USNR

PEOPLE who have lost the use of one hand can now learn to type with satisfactory speed and efficiency. For this they are indebted initially to Col. Robert S. Allen, prewar columnist-partner of Drew Pearson, who determined not to let the loss of an arm in battle stop him from resuming his career as a newspaperman. But the man to whom they owe the most is Commander August Dvorak, USNR.

Discouraged by his failure to master the standard typewriter with one hand, Colonel Allen turned to Commander Dvorak for help. In 10 years of exhaustive research in typing for the Carnegie Foundation for the Advancement of Teaching, Dvorak, then a professor at the University of Washington, and his associates had developed a simplified keyboard for two hands. Tests proved that normal typists could relearn to type on the simplified keyboard in 83 hours—and double speed records they had made on standard typewriters. Commander Dvorak believed a special keyboard might make similar gains possible for one-handed typists.

This article was written about a year after George Orwell introduced the world to Big Brother. Since closed circuit television cameras have become one of the most important and wide spread tools of “Big Brother” it seems a rather appropriate title for the article. The even mention the privacy aspect in comparison to the “much-debated wire-tapping”.

TV’s LITTLE BROTHER

By Creighton Peet

YOU CAN use it for anything—absolutely anything. It will show you what’s going on around corners, through walls, underwater, in the dark, at the bottom of an oil well—or inside the human stomach.

It’s TV’s little brother, a small and comparatively inexpensive wired television setup designed for industrial uses. Already three such devices are on the market. Diamond Power Specialty, a subsidiary of I.T.&T. has the Utiliscope; Remington Rand has developed its Vericon, and RCA the Vidicon. In one model the orthicon tube is the size and shape of a small flashlight, and its housing looks like a 16-mm. home movie camera.
