California Autoists View Movies in New Open Air Theatre

LOS ANGELES motorists, movie bound, may now sit in their cars and enjoy the latest sound pictures in a giant open air theatre recently completed.

The frame which holds the 40 by 50 foot screen is a structure 72 feet high and 132 feet wide. Three huge loudspeakers, each 22 feet long and 7 feet across the mouth, are mounted on top of the structure. These loudspeakers are directed at the tops of the cars, whose soft fabric is said to make an ideal sounding board.

The fenced – in spectators’ area holds 450 cars which are parked in lanes graded at an angle so that the cars point up at the screen. This inclination enables back-seat spectators to obtain a unobstructed view of the screen. Projection machines are in a low building in front of the screen, said to be the largest in the world. Installed in a low building in the second row, these machines work at an up-shot angle, instead of the customary down-shot used in indoor theatres.

There is something humorous about a rotary video phone.

CREATING A NEW WORLD WITH ELECTRONICS
How soon will you be able to see over the phone?

It may be sooner than you think. For the remarkable new Hughes tonotron—now used for high-fidelity transmission of maps and other navigational pictures to ships and aircraft—will make possible “face-to-face” telephone calls to and from your office or home.

The tonotron is only one example of Hughes Products leadership in research and development of electron tubes and related advances in electronics, such as transistors and diodes. It is with products like these that science will bring about the dynamic electronics era—in which you will have on-the-wall television, electronic control of factory production, and countless other marvels.

As one of the country’s largest electronics research and manufacturing firms, Hughes Products backs its semiconductors, cathode ray tubes, and industrial systems and controls with a long record of technical accomplishments. These include the “thinking” falcon air-to-air missile, and the self-directing Hughes Automatic Armament Control which is standard equipment on all Air Force interceptors.

Undoubtedly there is a time- and money-saving application of Hughes electronic products to your own business. A Hughes Products sales engineer will welcome the opportunity to work with your staff. Please write: Hughes Products, Los Angeles 45, California.

Giant Radio Tube Produced
CLAIMED to be the largest ever made, a new water-cooled radio tube demonstrated in Chicago stands about eight feet high. The tube takes 18,000 volts in operation. Rated at 250,000 watts each, five of the new tubes will be required to operate a transmitting station now being assembled.

What percentage of Scientific American readers could possibly be in the market for an Inertial Upper Stage? Frankly I would be worried if someone was planning to launch a satellite, stumbled across this ad and proclaimed “Aha! Now I know what to do about apogee injection!”

USE THE BOEING IUS AND FORGET ABOUT
WORRIES 1 THROUGH 11

If you’ve been thinking about choosing the right upper stage to get your own spacecraft off the ground, you’re no doubt going through a little anxiety right now. What about reliability? How about performance? Who’s responsible? Costs? Accuracy? Things like that. We’d like to make a case for the Boeing Inertial Upper Stage — the only all-inclusive, worry-free, complete package available.

THE TRANSISTOR’S 20th ANNIVERSARY:
How Germanium and a Bit of Wire Changed the World

The nuts and bolts of modern electronics, transistors lie at the heart of our rockets, computers, radar, radio, TV, and a thousand other devices

By W. STEVENSON BACON

The time: December, 1947. The place: Bell Telephone Laboratories at Murray Hill, N.J. The event: the invention of a new kind of electronic “valve” that can amplify signals—an invention so basic that it will virtually remold all science and technology.

Unlike the vacuum tube, it will not need a power-consuming hot filament, nor will it require a vacuum. Is it an impractical dream? Many skeptics think so.

After years of experimenting, Bell scientists, faced with repeated failures, have turned back to basic research.

UNRULY HAIR Stays Neatly Combed (May, 1938)

This shows how much hair styles have changed in the last 60 odd years. The “unruly hair” looks just like a modern haircut whereas the Glostora saturated model looks like he should be the evil rival in a Harry Potter movie.

UNRULY HAIR Stays Neatly Combed
Even Stubborn Hair Will Stay In Place
Costs But A Few Cents To Use — a bottle lasts for months

IS YOUR HAIR difficult to keep in place? Does it lack natural gloss and lustre? It is very easy to give it that rich, glossy and orderly appearance so essential to well-groomed boys.

Just rub a little Glostora through your hair once or twice a week — or after shampooing, and your hair will then stay, each day, just as you comb it.
Glostora gives hair that natural, rich, well-groomed effect, instead of leaving it stiff and artificial looking as waxy pastes and creams do.

Try it! A large bottle of Glostora costs but a trifle at any drug store.

New Electrical Devices from Europe

Electric Dancing Master
• ONE of Germany s popular radio announcers, Walter Carlos, has recently developed apparatus, illustrated at the right and below, for instruction in the newest steps. It is operated with a phonograph, carrying the latest dance music, synchronized with the mechanism, so that the feet of dancing couples, illuminated by concealed lamps (as the back view shows) traverse the small circle, executing movements which are to be followed by the learners. This may be watched from any point on the floor. Instructions to the dancers are given also by the phonograph.

Why Universities Need This Nuclear Research Reactor Now!

A THOUSAND PRODUCTS A MILLION IDEAS
BENDIX AVIATION CORPORATION

We have split the atom and made a bomb, but where we go from here depends largely on the strange structure in the photo and others like it. It is a nuclear research type reactor. Right now scientists have literally thousands of ideas for putting the atom to work in medicine, biology, chemistry, metallurgy. But they need this reactor to hatch the eggs—are handcuffed without it.

HERE’S WHAT WE’LL WEAR

Designers are already working on the styles the well-dressed space man needs to survive.

By Lloyd Mallan

Author of Men, Rockets And Space Rats

IT MAY or may not be true that clothes make the man, but one thing is certain: when he starts traveling in outer space his life will depend on the clothes he wears. For the past decade a unique group of clothing stylists has been hard at work determining the cut and materials of future fashions in space dress. None of this group is a designer by profession. Among its varied members are biophysicists; physiologists, anthropologists, electronic scientists and doctors of medicine. But they have one thing in common: all are willing to risk their own necks to perfect equipment that will make it safe for other men to fly through the alien vacuum of space. Acting as their own guinea pigs, they are locked into altitude chambers, spun wildly on centrifuges, and closed up in insulated rooms. In the process, they discover whether or not their space fashions are practical. And in order to be absolutely certain they plunge needles into their veins and spines, under their skin and over their brains. Wires connected to the needles carry their slightest physical reaction.

But out of it all, in just ten years, have come the means to prevent the horrors that could happen in space to the unaccustomed human body. Aeromedical scientists at the Air Force’s Wright Air Development Center (who supplied photos on these pages) now know that man can fly beyond the atmosphere without his tissues exploding, brain hemorrhaging, blood cells dying or lungs collapsing.

New Flying Battleship

Huge All-Metal Biplane, Tested for Uncle Sam, Carries Six Guns and four Tons of Deadly Bombs

NEW war terrors are forecast on this page in our artist’s conception of the new giant bomber, the Curtiss “Condor” swooping down to destroy an industrial center. From its three two-gun nests machine gunners pour streams of bullets at enemy planes attacking from any direction, while the man at the bomb controls manipulates them to drop the explosives through an opening in the fuselage. With 90-foot wing spread and two 600-horsepower motors, the plane, which is all metal, weighs, loaded and manned, over eight tons, including four tons of bombs. In recent tests for War Department and Air Service officials, the huge plane took off in 200 feet and made 100 miles an hour, flying and landing gracefully. It carries 640 gallons of gasoline and has a cruising radius of 800 miles
