Autogiro Blades Form Screen for Floating Ads After Dark (Sep, 1935)

This reminds me of all those persistence of vision gadgets like clocks and hubcaps.

Autogiro Blades Form Screen for Floating Ads After Dark

DISPLAY advertising at night by means of a magic lantern suspended beneath an autogiro, with the rotating blades serving as a screen, is a German inventor’s latest medium for placing a product before the public eye.

The magic lantern assembly is placed in a torpedo shaped carriage equipped with vertical and horizontal rudders to keep it in perfect alignment with the autogiro flying above. It can be raised or lowered by means of a cable, for focusing the advertiser’s message on the blades. When landing, the projector is drawn up into the fuselage.

To insure perfect reproduction of the advertisement, the under sides of the rotor blades are specially treated. The autogiro has been found to be particularly adapted for this type of aerial advertising because of its ability to hover almost motionless in the air, while the blades revolve fast enough to form an uninterrupted screen.

Nix on Parties – with my crop of Pimples (Mar, 1936)

Nix on Parties – with my crop of Pimples
Don’t let Adolescent Pimples kill YOUR dates!
AFTER the beginning of adolescence—from about 13 to 25, or even longer—important glands develop and final growth takes place. This causes disturbances throughout the body. The skin becomes oversensitive. Waste poisons in the blood irritate this sensitive skin, causing pimples.
Fleischmann’s Yeast clears the skin irritants out of your blood. Then pimples disappear! Eat 3 cakes a day, before eals—plain, or in a little water—until your skin clears.

Gillette Mach 1 (Jun, 1930)

The New Gillette Shave
Square blade-ends
Easier and safer to handle

MOST MEN like fishing—but not fishing down the drainpipe for a slippery razor blade. That’s one of many reasons why a vast army of men are praising the New Gillette Blade. Its square ends can’t slip out of soapy fingers; and how easily the new blade reaches into the tight little corners around the mouth, nose and ears!

There are so many other big improvements that you won’t appreciate them all until you try this New Gillette Shave yourself. Here are just a few: no more wiping or drying of parts. New blade resists rust.

“Razor pull” is banished forever by new reinforced corners of razor cap and cut-out corners of blade-Sounds almost impossible to give you all this remarkable new shaving comfort for only one dollar, doesn’t it? Yet your dealer has your New-Gillette Razor set waiting for you— your choice, in fact, of five styles of handsome cases. Additional new blades are priced at one dollar for ten and fifty cents for five.

Enjoy this new shaving thrill tomorrow morning by seeing your dealer on your way home tonight.

Lithium: The Miracle Element (Feb, 1956)

CATALYSTOF INDUSTRY
LITHIUM
The Miracle Element

cat’a-lyst: chem., the causing or accelerating of a chemical change by the addition of a … (catalytic agent) . . .

From air conditioning to welding fluxes, Lithium chemicals are the catalysts of industry. Multi-purpose greases, porcelain enamels, organic chemicals, pharmaceuticals, electric storage batteries, heat treating, glazes, electronic ceramics, metallurgy, brazing fluxes—all boast products made better by the addition of Lithium. Architectural porcelain enamels, porcelainized aluminum, low temperature heat treating, cermets, deicing of parked aircraft—these are wholly new fields with an interest in Lithium. Why don’t you consider the possibilities Lithium offers for your production process? Investigate the profit potentialities of this wonder metal. We will be glad to discuss it with you.

LICORICE may create new assets for you (Apr, 1953)

LICORICE may create new assets for you
Some business—perhaps yours—may soon find an additional source of wealth through licorice. This could happen by improving on some product now in use or developing a brand new one.
A prime example of product improvement from research is to be found in the tobacco industry. For many years now, licorice has been added to certain tobacco products to improve the taste, and also as a mellowing and conditioning agent. And a prime example of a new product as the reward for research is Foamite Firefoam— a foam of great staying power obtained from the “spent” root after completion of the initial extraction process.

Rand Ad: Tomorrow’s Design Today… (Sep, 1954)

Tomorrow’s Design Today…

Airplane design involves a staggering amount of data processing—a seemingly endless number of computations and tests between the drawing board and the production line. Every hour…every day … every week gained here brings the time when the finished plane takes off on its first flight just that much closer. In the aircraft industry, as in many other engineering applications, the Remington Rand ERA 1103 Electronic Computing System has proven how easily it can handle the most difficult research problems. Here are some reasons why leading aircraft builders and other prominent users are counting on the ERA 1103 these days:
Because of its ability to reduce large volumes of data at extremely high speeds, the ERA 1103 is the ideal computing system for scientific applications. Its speed is matched by many other outstanding characteristics: superb operating efficiency, obtained through large storage capacity … great programming versatility… the ability to operate simultaneously with a wide variety of input-output devices … and far greater reliability than any computer in its class. For more information about the ERA 1103, or for information about how you might apply the system to your particular problems, write to …
