Jungle to Factoryâ€”Trail of Auto Tire
Sidewalk from Chicago to New York Could Be Built from Rubber
Annually Consumed in Making Treads and Tubes
ABOUT seven-tenths of the value of rubber products made in the United States is represented in automobile tires and inner tubes, while 75 per cent of the world’s entire output of the material is consumed in their manufacture.
Until recent years the “rubber trail” took its traders into the wildest lands of the tropics, where they confronted untold hardships in order to provide the motorist with velvet shoes for the wheels of his car. Now, the rapid production of rubber on cultivated plantations makes the collecting of the various grades a far easier task.
Baskets Rolled Him To Riches
Grocer S. N. Goldman looked at a folding chair and came up with a $1,000,000 idea-collapsible wire pushcarts.
By Gilbert Hill
MOST folks look too far away for that “big chance.” It’s usually right in front of you, just daring you to do something about it.
S. N. Goldman, of Oklahoma City, believes this. He can prove it, too, because he’s built a multi-million-dollar business â€”on the side, away from his regular businessâ€”with a product known around the world, just by “looking close.”
Goldman is a groceryman. He operates 30 huge super-markets in Oklahoma in his Standard & Humpty Dumpty chain. But he’s just a little guy in the grocery business compared with some firms and yet many of his competitors couldn’t get along without him.
From the Stone Age to Wallpaper
Patterns of Today Reflect Designs, Coats of Arms and Tapestries First Used During the Middle Ages in Europe
ALTHOUGH the manufacture of wall-papers is one of the most interesting branches of the paper industry, comparatively few persons are familiar with its details or with how its development has kept pace with the progress of mankind from the earliest ages.
In the modern mill waste paper of various kindsâ€”catalogue trimmings, office records and overissue newspapersâ€”is reduced to pulp together with a certain amount of chemical, coloring matter and sizing. Since the output of this process does not have the color or texture necessary for the background, a coating of china clay, or plain ground color, is applied before printing.
Chicle Quest Beats Highway to Tropics
World’s Taste for Chewing Gum Once Known to Ancient Aztecs Builds Giant Industry in Few Decades
WITH well over a million dollars a week being spent in America for chewing gum, an enterprise that was launched amid much doubt on the part of the public, not so long ago, has become a leading industry.
It has been only a few decades since it was discovered that the combination of chicle and sugared flavors made a pleasing confection and in that short span of time, its use has become so common that today it is estimated the delicacy claims 75,000,000 devotees in America alone. Abroad, too, the demand for the sweet has caused abundant exportations of the commodity which now is known to almost every people under the sun.
This is an excellent, very long, 1982 National Geographic overview of all aspects of the microchip. It covers advances in silicon tech, how chips are produced, their uses and their effect on society. Topics include robots, hackers, digital watches, computers in the classroom, AI, early navigation systems, online news and shopping, telecommuting and more. Plus a ton of great pictures. Check out this rather prescient quote about online privacy:
“With personal computers and two-way TV,” he said, “we’ll create a wealth of personal information and scarcely notice it leaving the house. We’ll bank at home, hook up to electronic security systems, and connect to automatic climate controllers. The TV will know what X-rated movies we watch. There will be tremendous incentive to record this information for market research or sale.”
ELECTRONIC MINI-MARVEL THAT IS CHANGING YOUR LIFE
By ALLEN A. BORAIKO, NATIONAL GEOGRAPHIC EDITORIAL STAFF
Photographs by CHARLES O’REAR
IT SEEMS TRIFLING, barely the size of a newborn’s thumbnail and little thicker. The puff of air that extinguishes a candle would send it flying. In bright light it shimmers, but only with the fleeting iridescence of a soap bubble. It has a backbone of silicon, an ingredient of common beach sand, yet is less durable than a fragile glass sea sponge, largely made of the same material.
Still, less tangible things have given their names to an age, and the silver-gray fleck of silicon called the chip has ample power to create a new one. At its simplest the chip is electronic circuitry: Patterned in and on its silicon base are minuscule switches, joined by “wires” etched from exquisitely thin films of metal. Under a microscope the chip’s intricate terrain often looks uncannily like the streets, plazas, and buildings of a great metropolis, viewed from miles up.
From Cook Stoves to Tanks . . . They Roll from the Automobile Factories
By SCHUYLER VAN DUYNE
THE Detroit genius for industrial organization is sorting out the sudden chaotic avalanche of defense orders with its customary frantic and incredible orderliness. It is responding to the fabulous impetus of something like a billion and a half in armament orders assigned by the U. S. Government to the automobile industry. The vast industrial center, already a huge magnet, drawing raw materials and manufactured parts selectively from many parts of the country, is being called upon suddenly for all its reserve power. Its standard products, such as automobiles, trucks, and their accessories, were in extraordinary de-mand, but now there are imperative pleas also for airplane, marine, and tank engines; for the airplanes and the tanks themselves and for antiaircraft guns, cook stoves, ammunition components, refrigerators, Diesel engines, and a conglomeration of other articles.
Turning Out Photographs by the Million
Great Plants in All Parts of the Country Are Developed to Supply Quick Service and Assistance for Army of Amateurs
DEVOTED exclusively to developing films and printing pictures for an army of amateur camera enthusiasts, great plants have been built up in all parts of the country. During the “busy” months of June, July, August and September, when the weather is best suited to taking pictures, the seven largest finishing plants in Chicago handle more than 114,000 pictures daily. Several have an output of 8,000 to 12,000 every twenty-four hours, and many print more than 5,000,000 as an annual average.
In Cincinnati, a single company serves almost a hundred drug stores, employing a fleet of automobiles to collect the film and deliver the pictures to the proprietors who have found that the “side line” in film service is a profitable advertisement and brings in potential customers. In one week, one of the collectors for this company brought in 20,000 spools of film and as many as 17,500 prints have been distributed in a single day.
Beer Making Is Marvel of Industrial Chemistry
With the removal of national restrictions against the manufacture and sale of beer, American brewers are again in action. Their operations represent one of the most extensive applications of modern industrial chemistry. More than 2,000,000,000 pounds of malt, 650,000,000 pounds of corn and corn products, and 41,000,000 pounds of hops are a part of the vast consignment of raw materials that experts will turn each year into beer. On these pages, our artist shows how the transformation is accomplished in one big, and now active, American brewery.
Engineering the Magic Carpet’s Flight
Problems in Mechanics that Make the “Movie” Engineer’s Profession Recall the Magician’s Miracles
BUILD me a magic carpet on which I can ride; a flying horse like Pegasus and arrange a set so that I can disappear in a whirlwind.”
The “boss” of the moving-picture lot, without more ado, walked out of his chief engineer’s office, leaving that hard-working individual the three problems which he mentally added to the score or more of similar commands he had executed since the actual “shooting” of the scenes in the huge spectacle had begun months ago. For the engineering staff of the larger moving-picture producers is used to facing and conquering problems that for sheer unusual-ness are perhaps unrivaled.
