Farm Tractor Is Also War Tank
LIKE a broken down plow horse turning I into a snorting, spirited cavalry charger, a new farm tractor has been devised that can be converted into an armored tank equipped with gas and machine guns in a space of two hours.
The tractor is of the caterpillar type and is capable of surmounting anything from ditches to fallen trees. Its traction wheels are especially good for work in mud. Scrap metal was used to armor the original model.

“Radio Man” WALKS, TALKS,AND YODELS
TOWERING seven feet high, a strange “radio man” has just been completed after ten years of arduous work by August Huber, a Swiss engineer. Beneath its jointed steel body, the gigantic mechanical man is a maze of automatic switches, relays, and other controls. Microphones within the automaton’s’ ears pick up spoken commands and carry them to an intricate system of twenty electric motors that make the fantastic creature walk, talk, sing, or yodel at the will of its master. Power for these various activities is supplied by batteries concealed in the ponderous legs. When this modern monster talks through the loudspeaker installed in its chest, its lips move in time with its speech. An ultra-short-wave receiver installed in its torso enables the “radio man” to follow orders transmitted to it by radio from remote points.
The Story of Rope
By Andrew Hamilton
THE OLD INDIAN rope trick has amazed and mystified people for generations. A fakir throws a rope above the stage where it stands without apparent support, as stiff as a rod. The trick is simply this: an unnoticed four-pronged hook at the end catches a taut piano wire in the dim light above the stage.
This vaudeville stunt is not half as amazing as the miracle of rope itselfâ€”one of mankind’s most useful tools.

Odd Ferry Runs on Sunken Track
PERHAPS the strangest ferry in the world is the one operating across the gulf between St. Malo and St. Serven, Brittany.
The ferry is built on a high superstructure to allow for the rising waters during full tide in the English Channel. The superstructure rests on a set of wheels running on a submerged track set low enough in the gulf so that it in no way interferes with ocean going traffic. Large winches on shore, attached to under-water cables, supply the motive power.
The platform contains chairs and a warming house for cold weather.

New “ticker” for tanks
For a dependable tank “heart” â€” 500 horsepower’s worth of rugged air-cooled engineâ€”U. S. Army Ordnance looks to Lycoming’s precision production.
Rumbling over rugged terrain . . . crushing enemy obstacles . . . surviving heavy fireâ€”our “G.I.” tanks must have powerful, dependable engines to stay “alive” in combat. That’s why the Army Ordnance Corps relies on Lycoming to turn out air-cooled “tickers” for new-type tanks now in production.
Maybe you need a complete engine, or a single precision part. Maybe you have “only an idea” in the rough or blueprint stage that needs development. Or a metal product that needs precise and speedy fabrication. In any case-look to Lycoming! Lycoming has a long-tested reputation for meeting the most exacting and diverse metal-working requirements, both industrial and military. Whatever your problemâ€”look to Lycoming!
Lycoming’s wealth of creative engineering ability,its 2-1/2 million square feet of floor space, its 6,000-plus machine tools stand ready to serve your needs.
REPTILE SNAPS OWN PICTURE WITH FLICK OF THE TONGUE
Too fast to be seen by the human eye, the long tongues of chameleons and toads dart in and out as they eat. Their tongue tips are tacky and the food, usually small insects, sticks to the tips and is thrown back into their mouths. To photograph the action, London Zoo technicians designed a trigger device that fires a Dawe electronic flash lamp as the tongue hits the food
Top, stopped by an exposure of two mil-lionths of a second, tongue of chameleon is fully extended as it darts after food. Below, a toad gets his dinner. Right, the circuit used in top pictures. For photos of toad, two copper plates were used, one for the toad and the second for the food. Tongue completes circuit by touching food plate. Current was too minute to be felt.
Pocket-Size Exposure Suit
Exposure, one of the biggest trials of airmen downed at sea, is curbed by an inflatable rubber suit small enough to be rolled into a pocket in the collar of a Mae West jacket. It weighs less than three ounces and provides air insulation against cold and damp. The suit is being tested in England and may soon be adopted as standard equipment for Royal Air Force crews.

NEW DEPARTURES OF TOMORROW
Think of dashing through your correspondence with this imaginary scribe! It converts your voice into electronic impulses which type, micro-record, fold, insert, seal, address and stamp letters almost as fast as you can dictate!
It’s just a notion now! But when some foresighted engineer works it out, you can bet New Departure will be called in to design the right ball bearings to keep these intricate parts working smoothly. New Departure works with engineers right from the planning stage to develop the exact bearing for even the newest departure in design.
