Eye-Glasses Double for Microscope
EYE-GLASSES which can be used instead of a microscope have been invented by C. Dreisseg of Hamburg, Germany. The glasses obtain their microscopic power from specially treated dark paper.
This paper changed the focus of the eye so as to magnify the size of a fixed object. Even minute particles can be distinguished. The dark paper is encased in a leather band which fits snugly around the eyes to exclude all possible light rays. The novel glasses are ideal for student use.
Expert Tastes Soap for a Living
TESTING soap by taste is one of the chief duties of Joseph Strobl, chief soap maker for a Los Angeles company. He samples the cooking product much like an expert chef. Chemical tests take too long at critical stages and are said to be less accurate than Strobl’s tongue.
This is the first in a really weird series of ads I’m posting from the Ford Instrument Company. All of them involve these two little dolls doing things like launching missiles or torpedoes, shooting guns, or manning radar stations. Very odd stuff.
about missile guidance
…AND FORD INSTRUMENT COMPANY
To make sure that a missile hits its target, Ford Instrument provides it with a guidance system that is sensitive to the variable conditions it meets along the way. If you have problems in this field, it will pay you to talk them over with Ford engineers. Guided missile devices are typical of the systems that Ford designs and manufactures for the Armed Forces and the Atomic Energy Commission. Thousands of Ford specialists are now working on such projects as electronic, hydraulic, mechanical and electrical servo-mechanisms, computers, controls and drives.
Device Measures Musical Talent
A YARDSTICK for the measurement of musical talent, an automatic tone-variator, is now being used at Northwestern University to determine students’ ability to determine exact tonal pitch.
The machine contains 14 tuning-forks, set within one-quarter tone of each other. Two notes are struck in quick succession, and the students are asked which note was higher. Those that can detect the higher note consistently are keenly encouraged to study music. They are considered to be musically apt and talented.
Students with less sensitivity to tone are advised to study instruments with broader tone distinctions such as pianos and other keyboard instruments.
This is pretty rediculous. I particularly like the part about living in 167 degree heat.
FOUND â€” King Solomon’s Gold Mines
THE SECRET OF WAR-TORN ETHIOPIA
by JAMES NEVIN MILLER
COUNT BYRON DE PROROK, famous explorer, is again back in the United States after a series of adventures that would make an Arabian Nights fable seem weak and colorless in comparison. He was successful in locating the exact spot where the legendary King Solomon of Biblical fame once mined fabulous tons of gold.
More important, and perhaps the reason for the Italian hosts pushing their way into Ethiopia, these ancient mines are being worked today on a scale that staggers the imagination. From a volcanic mountain top, de Prorok beheld countless slaves, both men and women, toiling night and day to uncover the heavy golden nuggets.
But let this distinguished archaeologist tell his own almost unbelievable story:
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.
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.
Trapped Rat Shoots Self and Photographs the Fatal Event
TRAPPED in an ingenious contrivance built by George W. Fenner, Syracuse photographer, a hungry rat shot himself and left a picture of the event in a camera trained upon the device.
A piece of bait was suspended from a wire at one end of the trap. Nibbling eagerly at the bait, the rat released a catch which dropped a spring-operated hammer, tripping the trigger of a revolver mounted at the opposite end of the trap.
The shot not only killed the rat but also cut a piece of string connected with still another spring. The latter set off a flashlight, supplying the illumination necessary to take the picture. In addition to the camera and lethal apparatus, a watch hung near the gun recorded the time of shooting.
Mechanics Masquerade as Men from Mars
NOT weird, helmeted men from Mars, but merely airplane mechanics carrying metal propeller-hub protectors are pictured in the curious photograph reproduced above. Because of their unwieldy shape, the hub spinners were easier to carry when held over the heads of the workmen as they walked out to install them on giant 1,200-horsepower transport-plane motors. The spinners help prevent the formation of ice on propeller hubs during winter and early-spring flying.
Women Stars Wrestle Under Water
ONE of the world’s strangest athletic events was held recently when Dolly Dalton, Canadian champion, engaged Dixie Taylor, southern women’s champion, in an underwater wrestling match at Silver Springs, Florida. The remarkable clearness of the water enabled spectators to follow every-move of the contestants. Good wind is essential for this strenuous sport.
