Bookkeeper on Moving Platform Saves Time in Reaching Files

Time and effort in referring to a large filing index in a busy office are saved by placing a billing machine and its operator on a platform which moves on rails. The carriage is anchored by a hand brake, conveniently placed, and when the operator wishes to move to another case, she releases the handle and pushes herself, machine and all, to the next position.

The models are nice, but I love the hat.

Junior Styles Tomorrow’s Cars

Watch out, you professional car designers—these up and coming ‘teen agers will have your jobs!

THE automobile of tomorrow should have a rear engine, better visibility and smooth and unbroken body lines—so think the youthful winners in the 1946 competition of the Fisher Body Craftsman’s Guild.

The lads seem to be on the beam. Look at their models!

David W. Whitman chiseled and filed his car out of pine. Little Virgil M. Exner, only 13, turned out a job nearly the equal of a professional designer’s, the experts say. Virgil is the son of the chief designer for the Studebaker Corp., and seems to have inherited his father’s talents. In a well-equipped workshop, with side trips to a nearby dime store, he made a beautiful plaster of Paris rear-engine model with radiator intakes along the front edges of the rear fenders.

Yes, kill a snake in only eight and a half minutes! Of course this would only really work on animals that aren’t allowed to move. It seems like stepping on the snake would have been more effective.

Death Ray Effective On Snakes
A DEATH ray which proved its effectiveness before a San Francisco jury has been developed by Henry Fleur, Pacific Coast inventor. The apparatus which employs a light beam impregnated with infra-red rays successfully killed a snake in 8-1/2 minutes. A lizard was put to death in less than 6 minutes with only 30 seconds required to kill certain termites. Mounted on an adjustable tripod, ray can be aimed at objects in the same manner as a searchlight. The beam transmits a stream of high frequency vibrations.

This is pretty awesome. Anyone know if it’s still around?

Periscope House

YOU walk across the green-lawned, palm-hemmed park overlooking the Pacific Ocean in Santa Monica, California, and climb the stairs to the little house in the picture above. Your party gathers around a circular rail in the center, the door is closed and at first all is darkness.

Then, slowly and as if by magic, the scene you left outdoors a few minutes before appears on the revolvable table in front of you. Colors are perfectly natural. Strollers in the park move about, quite oblivious to their observers.

CAUGHT BY THEIR FINGER PRINTS

During the past 32 years the I. A. S. has trained hundreds of men at home to fill positions of responsibility and steady pay as finger print experts. This fascinating, profitable profession can be learned at home during spare time. More than 800 American Identification Bureaus employ I. A. S. graduates or students. Write today for complete list of these Bureaus.

That’s pretty scary looking.

CAP AND MASK IN ONE PROTECTS DIVER’S EYES

Bathing fashions in the course of centuries have seen many novelties, but it remained for a Los Angeles, Calif., designer to think of this new headgear, which is a combination cap and face mask in one.

When the first wearer recently appeared on the Los Angeles beach, the startling, round eyeholes of the mask might have suggested to a fanciful observer the appearance of a feminine Martian or a lady robot. Despite its oddity, the mask serves the practical purpose of protecting the eyes and ears in diving. Celluloid eyepieces keep out the water. The lower portion of the mask covers half the swimmer’s face, leaving the ‘ nose and mouth uncovered. It may be turned up when not needed.

Fertilize the Largest Farm in Illinois With Electricity

CHARGING the soil with electricity as it is being plowed is the newest form of fertilization. The largest farm in Illinois, 13,645 acres in a single tract, is treated in this manner. The plow and apparatus used are shown at left. In addition to bringing an improved yield of crops the electric current kills harmful insects and weeds as it flows through the soil.

How can you not love an article with quotes like this:
“By the time you get down near Absolute Zero everything in the world is frozen harder than a pawnbroker’s heart…”

When this article was written the record low temperature achieved by scientists was .0015 K. The current record is 0.00000000045 K.

Actually things get MUCH weirder near absolute zero then they thought at the time. Check out these links for more.

So You Think THIS Is Cold?

Teeth chattering? Fingers numb? Well it’s warm compared to what the lab boys call Absolute Zero.

By Lawrence Sanders

“Tis IS BITTER cold and I am sick at heart,” quoth Hamlet. And right now most citizens are hunching along, swaddled to the ears against the cold and muttering, “You said a mouthful, Bard.”

Is it cold enough for you?

As a matter of fact, it probably is cold enough for you—whether you live in Weeping Water, Neb. or Hiram, Ga. One man’s heat wave is another man’s cold snap and a Key Wester can be just as uncomfortable at 40° F as a Bald Eagle, Minn, resident when the mercury goofs off to—40 °F.

Information at Turn of Dial

WORKING on the telephone dialing principle, London subways have installed a machine which gives passengers the location of a particular place, amount of fare, and platform from which train starts—all at a mere turn of the dial.

In 1930 airplanes of the 94th Pursuit Squadron were flying around with little swastikas on the side of their planes. (second page, second picture) I wonder how long that lasted.

Romance of Plane Insignia Dates from World War Days

DURING the World war the various fighting squadrons of the Air Service adopted the policy of painting insignia on their airplanes.. These insignia reflected the experiences of the pilots or of the squadron in war, or perhaps had no significance other than that which the original design itself intended to convey. The squadrons of the United States Air Corps have, as far as possible, continued in peace the same insignia as were used during the World war.

Insignia, besides promoting an esprit de corps provides a means of identifying the planes of a particular squadron. At the Air Corps maneuvers held at Mather Field, California, this spring, squadrons were assembled from all parts of the United States; Pursuit from San Diego and Detroit; Attack from Galveston; Bombardment from Langley, Va., and Observation from San Francisco. The insignia of the various units, to those who were not abroad in 1917-18, represented considerable imagination and initiative in their preparation, but to those who served in Air Units during the war they awoke memories of the past and brought forth many reminiscences.

World’s Smallest Talking Machine

HERE is a portable talking machine that is thoroughly “portable.” Reputed to be the world’s smallest, the miniature, shown on the right, is constructed of steel and leather, and looks like a folding camera.

The horn is carried inside the machine and the same screw that is used for fixing the record to the plate is used in closing the apparatus. It weighs slightly over three pounds and tits in a coat pocket.

This is the Supersonic Barrier

Extraordinary things happen close to the speed of sound.

BY WILLY LEY

FOR millenia man dreamed about flying—and did nothing about it. In 1783 the balloon was invented and people could fly wherever the wind happened to blow them. More than a century later the airplane was invented—and people began to be able to fly where they wanted to go.

Now, forty-four years later, man wants to fly faster than sound. He will do it. Aeronautical science is close to this goal; it may take only a year or two. But there are difficulties, and most, of them are tied up with something which is called a Mach number. (The term honors the Austrian physicist Dr. E. Mach, who was one of the first to investigate the problems of air resistance at high speeds.)
