USE CAR’S EXHAUST TO CLEAN CUSHIONS
Using the exhaust gas of the automobile to clean the upholstery is the accomplishment of a recently invented device. An aluminum attachment is fastened to the exhaust pipe and the engine is allowed to idle. As the exhaust gas passes through this device suction is created at the inlet hole. Collected by a nozzle, the dust and dirt are drawn through the hose and expelled into the air at the rear of the car. It is made in three models, for cars of different size.

It does not sound like this trip was very fun.

The Real Truth About the Wilkins Polar Sub

The real story of the submarine Nautilus, which set out on a fantastic Jules Verne expedition to travel under ice to the North Pole, and which now lies abandoned in a European harbor after an amazing succession of catastrophes, is here told you for the first time by a member of the expedition. Fascinating, thrilling— an “inside” story—scientific adventure in the raw!

by ALFRED ALBELLI who interviewed Arthur O. Blumburg, Chief Electrician’s Mate of the Nautilus

ARTHUR O. BLUMBURG Mr. Blumburg has been for 15 years in the United States Navy submarine service, and was granted a leave of absence to lend his expert services to the Wilkins Polar Submarine Expedition. That Mr. Blumburg was one of the most valued members of the crew, is testified to by the following sentences taken from a letter written to the Secretary of the Navy by Commander Sloan Danenhower of the Nautilus: “Arthur O. Blumburg had charge of recommissioning the electrical department, the installation of the storage batteries and special gyro compass, the automatic pilot, and other electrical equipment. He accomplished this work with great dispatch and efficiency, and has been a faithful, zealous, and efficient head of the electrical department throughout the entire voyage.”

The old issues of Popular Mechanics are organized rather badly. In this case there was a section called “Radio News” with two or three pages of articles and then this pictorial with no preface or explaination. The pictures are pretty great though so I hope you enjoy them.

I love the last line of the ad which says: “Made in Canada, too.”
Does that mean it’s made in American AND Canada? Or are they saying, “Oh, by the way, it’s made in Canada.”?

Phonograph Carried as Vanity Case Plays Standard-Size Records

Carried like a vanity case and about the same size, a collapsible phonograph that plays standard records has been invented.
The motor is wound by a detachable crank and the horn opens and closes like a telescope so that it can be folded into small space. The entire instrument weighs but little and is said to reproduce tones as satisfactorily as many larger and more expensive machines.

This is a chapter about information from a really cool text book called The World of Science, published by Golden Books in 1954.
Also check out another chapter I posted called “COMPUTERS THE ELECTRONIC BRAINS”

INFORMATION: TO SEND AND USE IT

CUTTING A DISK

In the sound studio a singer is performing a popular number. The microphone suspended from overhead wires picks up the sound. If a whole group of musicians were being used, more microphones would be spaced about. In the control room at the back stands the sound engineer listening through earphones and turning dials on the crowded panels before him.

Soon, as a result of this recording session, tens or hundreds of thousands of people will be able to flick on a phonograph and, wherever they are, hear this same singer with her guitar performing this same popular tune, as often as the hearer chooses to repeat it.

SHIELD ON EYEGLASSES PROTECTS THE NOSE
Equipped with a shield that completely covers the nose, these new sun glasses may not impress the beholder as an aid to beauty, but that is what they actually are. The shield protects the wearer’s nose from sunburn and consequent redness. A Los Angeles inventor designed it.

It’s Time for Canning in the Tennis Factories
This is the season for canning corn—and tennis balls. Above, balls being packed in cans to keep them “live”

Thousands of Americans are smashing tennis balls over—and into nets in parks and club grounds and thousands more are engaged in busy factories where rackets, balls, nets and equipment are produced. What you see, above, is not a parking lot for balloons but hundreds of tennis ball centers on drying racks in a factory. They have been coated with cement and are awaiting the proper moment for being covered

Above, a final stage in manufacture of tennis balls; putting on outer covering, sewing and “spooling”—ironing the seams down. Below, at right, the beginning of a tennis racket. Here a factory worker is bending strips of ash into shape. Rackets must conform to high standards as to weight, balance and stress

… Here is the Surprising Truth about

The BRUTAL BULLY and the Timid Soul

DR. WILLIAM K. GREGORY, distinguished scientist of the American Museum of Natural History, in the first articles of this series, has given the absorbing history of the tiny living speck from which all life arose and sketched its slow development into Man. The manner in which Man passes his characteristics on to his offspring and the functions of the ductless glands were described by Dr. Herbert Ruckes, of the Biological Faculty of the College of the City of New York. Last month, Dr. A. T. Poffenberger, head of the Department of Psychology, Columbia University, New York, told Michel Mok, staff writer, that our emotional life is based upon fear, anger, and love. In this talk, Dr. Poffenberger explains how circumstances and civilization influence and mold our individual emotions; why one man becomes a racketeer and another a useful citizen.

Sterility is Now Being Overcome

There is new solace for empty arms as science helps the limping stork

By Lorine Pruette, Ph.D

DYNASTIES have been changed and the course of history affected by the failure of particular unions to be fruitful. Catherine the Great took a lover because of the necessity to provide the throne with an heir and introduced entirely new strains into the royal family of Russia. Henry the Eighth of England made his numerous excursions into matrimony, in part at least, out of the desire for a male heir. As a by-product of his excursions we have the break with the Catholic Church, the establishment of the Church of England and vast changes in England’s internal affairs and in her relations with the continental countries.

Henry’s children mounted the throne in succession, but all three died without heirs. Had his daughter Mary borne a child to her husband, Philip of Spain, much history might have had to be rewritten and certainly England would have been returned for a time to the bosom of the Mother Church.
