Tricks of the House-Wreckers

by ALFRED ALBELL

Have you ever watched a huge factory chimney being leveled to earth with a charge of dynamite? If you have, you will have wondered how the wrecking crew was able to make sure in advance that the shattered chimney would fall to the ground in a spot where it would miss adjacent buildings. The trade of house-wrecking has its full complement of tricks which are explained in this fascinating article by Mr. Albelli.

Ice-Cream Bars Are Made Easily with Dipping Outfit (Jun, 1935)

Ice-Cream Bars Are Made Easily with Dipping Outfit

Less expensive than some other equipment on the market, a new ice-cream bar maker has several desirable features. One is a spreader that holds the bars, with the flat, wooden sticks inserted, in position for dipping in chocolate or similar coating mixture. After dipping, the bars are hung on a rack to dry, the spreader and dipping apparatus being arranged for this purpose.

Modern Wonders of an Ancient Art (Jun, 1936)

Modern Wonders of an Ancient Art

By H. W. MAGEE

Part I PORCELAIN enamel is older than history and yet—in its modern applications—it is as new as tomorrow. Fifteen centuries or more before the dawn of the Christian era, someone heated a batch of minerals and produced a glasslike substance which he found could be fused to metal with the aid of heat. In the next two thousand years or so man utilized this knowledge mainly to produce beautiful cloisonne vases, medallions, jewelry and other ornaments.

LITTLE GIANTS of INDUSTRY (Mar, 1941)

LITTLE GIANTS of INDUSTRY

IF YOU were to select the most remarkable characteristic of modern industry, probably the first thing that would come to your mind is size—huge buildings, gigantic machines, massive ships, great airplanes, bulky trucks, mammoth dams, tall derricks, towering excavators, long trains. Man himself seems puny and weak beside his creations.

LINOLEUM- Another Industrial “Accident” (May, 1936)

LINOLEUM- Another Industrial “Accident”

An inventive mind and a can of paint left open by accident were the co-founders of the great linoleum industry. Its manufacture is as strange as its origin.

THROUGH all the centuries man’s progress is reflected in the homes he has kept, and is readily traceable in the floors of those homes. Prehistoric men paid little attention to floors, but when the long arm of the Caesars reached out into the Orient, they found floors of inlaid ebony, teakwood, mosaic and pearl, but only in the homes of the rich.

Workers Wear Space Suits in New Gas-Filled Factory (May, 1959)

Workers Wear Space Suits in New Gas-Filled Factory

EXOTIC metals that can survive the heat barrier of hypersonic flight soon will be mill-worked at a white-hot 4,000 degrees in a forbidding atmosphere of argon gas, similar to that inside an incandescent light bulb.

Men working in this out-of-the-world gas-chamber metal mill will wear “space suits,” trailing umbilical cords plugged into air-breathing and exhaust manifolds.

Should a lifeline break, a man might live a minute or two—as helpless as if he were out in space or under water without an oxygen supply. Crash doors will provide a quick escape. But in case he is injured or some obstacle gets in the way, he will have an emergency air capsule to keep him alive until rescue comes.

Pretzel Bending Machine Solves Problem (Nov, 1936)

Pretzel Bending Machine Solves Problem

Accomplishing what once was considered as impossible for a machine, a new pretzel bender turns out 900 completely twisted pretzels per minute. It more than equals the work of fifteen expert pretzel-bending girls. The machine is an odd assembly of wheels, endless belts, air hose and electric motors, yet it handles pretzels with far more skill and speed than the best worker. Circle, top, machine at work. Center, pretzels ready for cooking. Bottom, expert worker bending pretzels by hand .

Maker Of The Maestro’s Wand (Aug, 1941)

Maker Of The Maestro’s Wand

It started as a joke, but Isaac Cary turned it into a business. Whether it’s symphony or swing, the odds are heavy that the leader of the band is using one of Gary’s custom-made batons.

by Lester David

APPLAUSE beats in waves through vast Carnegie Hall as the spotlight picks out the frail little man advancing to the conductor’s stand. He bows deeply and faces the orchestra, arms outstretched. In his hand he holds a slender, white, beautifully proportioned baton. A hush settles on the auditorium … he taps his stand twice, sweeps his baton upward and music flows into the hall. Arturo Toscanini is interpreting a master.

How Photographic Film Is Made (Oct, 1940)

How Photographic Film Is Made

“Mustard” plants and chemical “noodles” contain the elements that must be put into film base and emulsion before your camera can do its work.

PHOTOGRAPHY has wedged its way into our daily lives so securely that we do not view it with the alarm and mysicism people did when Daguerre announced the first successful photographic process one hundred years ago, in 1839. We have come to expect and accept the seemingly impossible with little exhibition of surprise or enthusiasm. This is, in many ways, unfortunate, for the real joy of science comes from knowing her intimately—knowing how she can make so few characters play so many parts, disguised outwardly but working inwardly to the same objective.
