Science In Pictures
Rubber Fenders are the answer to the dent problem of motorists according to Inventor (and Doctor) Clauss B. Strauch, of Hazel Green, Wis. He says it’s no gag. The rubber fenders are inflated.
Elephant on Plastic at left demonstrates strength of a new building material made of paper and cotton impregnated with phenolic resin. The panel weighs only 30 pounds (one-fortieth as much as standard building materials) while the elephant weighs four tons.
Costly Library Books Loaned to Readers in Film Rolls
CONTENTS of the original copies of valuable books are being filmed by many libraries throughout the country and the rolls loaned out instead of the books themselves. The reader may then study the material by reflecting it on a screen by a tiny projector that is loaned with the rolls. A roll is placed in a machine turned at the reader’s convenience by means of a tiny handle.
Death speeds up Search for New Arctic Route
TWO expeditions, one German, one British, established outposts upon the forbidding ice cap of central Greenland, last year, seeking a possible landing place for transatlantic airplanes.
Searchers with airplane and dog teams found Augustine Courtauld of the British Arctic Air Route Expedition, this spring, hungry and unshaven.
Colored Underwater Lights Lend Magic Beauty to Garden Pools and Fountains
By Walter E. Burton
THE magic touch of light will transform your garden pool into a jewel that gleams in the darkness with astonishing beauty. Goldfish, plants, and other details of the submarine world that you normally do not see, become a source of endless pleasure. If there is a fountain or miniature waterfall, light will bring out its hidden beauty. A swimming pool, whether indoors or out, will be doubly serviceable if it is equipped with an underwater lighting system.
HIS SCRAPBOOK IS REAL ENCYCLOPEDIA
Five years ago Arthur Carlson, subway worker of Brooklyn, N. Y., began to clip interesting articles from Popular Science Monthly and other magazines. Now he has a 140-page “encyclopedia” that would be the envy of many a scrapbook devotee. Spending eight hours a day, it would take about a week or two, he estimates, to read it through.
RUBBERS FIT IN UMBRELLA
Completely equipped for rain is the user of a two-in-one umbrella containing a pair of rubbers within its handle. Tightly rolled to occupy little space, they are withdrawn in a jiffy as shown above. When the handle is in place, as below, the umbrella appears to be an ordinary umbrella, in every way.
Noted Scientists Grapple with Food and Fuel Famine
Search for Secret Process by which Plants Harness Enormous Energy of Sunlight
By Thomas Elway
THE coal and oil supply of the , world is rapidly being used up. What shall we do when it is gone?
Practical men have been asking themselves that question for a decade, and now the scientists of America have decided to answer it. They realize that a solution must be found, or civilization will perish.
What I find interesting about this is, was this just a test sign? Or did people really used to go into a gas station and shop for gasoline by brand?
Simple Device Makes Signs Instantly Interchangeable
WITH the price of gasoline changing almost daily, station attendants will welcome the new metal sign system, shown on the left, which allows price notices to be changed in a jiffy—without altering the sign’s neatness.
The name plate is equipped with a bracket which slips over the metal post and is clamped tight. The lower edge of this plate is bent to provide a flat sleeve and a longitudinal slot. Price plates have a flat, solid head which slides into this slot and is locked by pressure.
I had to do two sleep studies last year and I can tell you, they now collect just a bit more data. It is really amazing the number of wires and sensors they can stick on to you and then expect you to go to sleep.
Scientific Sleep Meter
AT the University of Chicago, Drs. Cooperman, Mullin and Kleitman have been studying sleep; and have reached the conclusion that the average person sleeps better with a cup of coffee just before retiring than without it. Also, that alcohol produces early sleep, but later wakefulness.
I don’t know the current status of trademark law, but I don’t think you get simultaneous trademark registration among many countries. I think you have to register in each. This does remind me a lot of domain name squatting.

TO thwart the genial trademark pirates of the Spanish main, the governments of the twenty-one republics of the New World are being encouraged by Uncle Sam to put into early practice a form of “team work” new alike to business and statecraft.
