Industrial Workers Will Lose the Sight of One or Both Eyes TODAY
AN ALARMING COST TO INDUSTRY Yet Almost Wholly PREVENTARLE

Of the 17 serious eye accidents in industry that will happen in the next 24 hours, 16 could be prevented now by use of safety goggles. Eye accidents are estimated to cost industry $5 per shop worker per year— an alarmingly high figure. Yet, according to the Society for the Prevention of Blindness, 98% of eye accidents can be prevented by the use of safety goggles —at an average cost of only $1.50 a pair. Are you overlooking this opportunity to effect a substantial cost reduction? If so, we suggest you get in touch with your nearest AO Safety Representative for advice and help in establishing an adequate eye-protection program in your plant.

The Secrets of Making Marionettes

By RUFUS ROSE

ARTISTS’ oil paints, obtainable in tubes, offer the best medium for painting marionettes. Flat white paint is used as a ground color to cover all exposed parts. When dry, white enamel is used to get a gloss on the teeth and eyeballs, using a small camel’s-hair brush as in Fig. 30. To get flesh color, mix burnt sienna with flat white paint, sometimes adding small quantities of red, yellow or blue to bring out various skin shades. Apply a spot of vermilion in the center of each cheek and blend it into the flesh color of the face. The lips are painted with a suitable mixture of vermilion and burnt sienna. Shades of blue or brown, or a mixture of both, are used to make eye shadows and lines to imitate wrinkles in the face and hands.

Swim Coordinator Really Teaches

WHEN learning to swim, so many people emulate a wet hen that they get nowhere at all. But with the new “Swim-Co-ordina-tor the novice is assured of learning the right way to swim from the very start.

You lay yourself on the apparatus, as Bernice Claire is doing in the illustration, and by turning the hand cranks your arms and legs move up and down in exact duplication of the American crawl. Thus, after one or two lessons in “dry land” swimming, even those who have never swam before can handle themselves capably in the water. The device is installed at the Hotel Sheldon Pool, Gotham.

This seems like a REALLY bad idea. Put your baby on the end of a spring, right in front of the windshield… bright.

Baby Bounces in Safety Chair

A SAFETY chair which combines the enjoyment of a spring ride for the baby with assurance to the mother that he will not get hurt provides a solution to the problem of baby tending for the busy housewife.

The chair is built high to support the baby’s back and is set on a strong steel spring leaf fastened to a slot in the floor. The baby’s legs straddle a hobby-horse head which prevent him from falling out of the front. Stirrups provide a natural rest for the child’s feet.

The spring of the safety chair may also be slipped into a slot in the auto floor, and it will eliminate all heavy shocks to provide baby with a smooth, comfortable ride in spite of rough and rutty roads.

Auto Seat Gives Infant Comfort – AKA “Kiddie Catapult”

My girlfriend actually bought me one of these at a garage sale a while back. I’ll have to find it to make sure I have a genuine Thoresen model not one of those “cheaper, erratic, look-alike, all-plastic calculators imported from the Orient, near communist China”. Apparently being made in a country near communists brings down the quality of your goods. Unlike West Germany which was right next to communist East Germany…

Also, why can you only use the wallet to hold $1, $5 and $10 dollar bills. Is there something wrong with the $2, $20 and the $100? Do you need an advanced model to handle those denominations?

Maybe No Noise in Future Wars
EXCEPT for the bursting of high explosive shells, wars of the future may be comparatively silent affairs, thanks to a new silencer just perfected by Ronald Chapman, of Caterham, England.

The silencer, which comprises a small cylinder about two inches in diameter and six inches long, fits onto the end of the gun barrel as demonstrated in the accompanying photo. The sound muffling mechanism which the inventor has not made known, absorbs more than four-fifths of the noise, and all flash and smoke.

With these qualities, the device becomes ideal for snipers and machine gunners in war time, and maybe use for it can be found in the gangster empire, where an “on the spot” job could be achieved with a minimum of disturbance to peaceful non-combatants.

Electrons in Overalls

WHILE millions of men throughout the world have been frantically engaged in destructive warfare waged by new and secret devices, during the last few years, several hundred earnest American scientists have been just as busy training an army of their own and perfecting a weapon which may go a long way toward making a better civilization tomorrow.

The army of the scientists is an army of electrons, countless billions strong. The weapon is the electronic tube—no secret weapon, to be sure, because among the common types are the tubes in your radio.

Odd-shaped “Flying Wing” Is Model For Proposed Sky Liner

KONRAD KRAFT, a young engineer of Thuringia, Germany, has invented a radically new type of airplane in which the wing surface is broken into the form of a W for greater stability in flight. Using a model with a wing span of 2,200 millimeters and a depth of but 280 millimeters Kraft proved that his design was not affected by side winds, and would climb more rapidly than other models. He plans to use his design for a great tri-motored plane having landing wheels in the wing angles and a roomy passenger compartment between the wings. Fuel would be carried in tanks in the hull.

Trial by “Sound Jury”

After Bell Laboratories engineers have designed a new talking circuit, they measure its characteristics by oscilloscopes and meters.
But a talker and a listener are part of every telephone call, and to satisfy them is the primary Bell System aim.
So, before the circuit is put into operation, a “sound jury” listens in. An actual performance test is set up with the trained ears of the jurors to supplement the meters.
As syllables, words, and sentences come in over the telephones, pencils are busy over score sheets, recording the judgment of the listeners on behalf of you and millions of other telephone users.
Targets of the transmission engineer are: your easy understanding of the talker, the naturalness of his voice, and your all-around satisfaction. To score high is one of the feats of Bell System engineering.
