TYPEWRITER REPLACES TYPESETTER IN NEW METHOD OF COMPOSITION
PROMISING a new departure in the methods of printing books, newspapers, and periodicals, a recent invention enables any typist to produce perfectly aligned columns of copy with an ordinary typewriter, since it corrects the usual irregularity of the right-hand margin. The resulting copy may be reproduced by standard photo lithographic methods, eliminating the need for present-day typesetting, matrix, and stereotype equipment. A sample of the new typewriter printing is shown in the center illustration above.

How Mechanics Make Your Movies
by H.H. Dunn
All of the money made in the movies does not go to the big stars and directors. Queer jobs in the studios support a small army of expert technicians.
A LARGE and shiny car pulled onto the lot, and an active young man ran from it into the main building of the RKO Pathe Studio at Culver City.
“‘Big Shot’ director?” I asked.
“Best shot in Hollywood, also director,” answered Bill Rice. “Gets paid every time he misses a star, and he has missed hundreds of them. Read the rest of this entry »
SAFE FUN for HALLOWEEN
UPON arriving, every member of this Halloween party must be fingerprinted and “mugged” as regular routine for identification records in the archives. The newcomer presses the thumb of his right hand down on the “ink pad,” for which purpose ordinary carbon paper will do. This is pasted to a piece of sheet metal on a small box which contains two dry cells and a Ford vibrating coil, connected together as shown in Fig. 1. The “guard” presses a push-button switch the moment the guest touches the carbon paper and has his left hand on the table directly over another sheet-metal plate also wired up as indicated.

AN EYE ON SPACE
By Dr. Dan Q. Posin
PROFESSOR OF PHYSICS, DE PAUL UNIVERSITY SCIENTIFIC CONSULTANT AND ADVISOR, COLUMBIA BROADCASTING SYSTEM
EARTHLINGS ARE PREPARING many kinds of fuels to propel themselves out of this world.
1. Gasoline is inexpensive, and its flow is easy to control. It is, however, hard to store and manipulate. It is not too reliable, as the rocket using it has to be intricate and there are many chances for breakdown. Thrust is moderate to low, amounting to about 270 pounds from one pound of fuel burning per second. Kerosene’s kick also is fairly low.

“Human Quoits” Is Amusing New Bathing Beach Game
YOU have to use your head in this amusing new game of “human quoits” in which padded barrel hoops are tossed at the heads of players buried in the sand, the object being to “ring” them. It’s a game amusing to spectators as well as players, and one in which the human targets get quite a thrill, since, buried in sand as they are, dodging is impossible. If you want to try out this game on your own beach, light weight hoops can be made by winding cotton batting and a covering fabric around a core of light gauge steel wire.
High-Speed Escape
So that high-altitude ball-outs will not kill, the fast new planes are being designed to cone apart, allowing a safe drop in a tight capsule.
BY ERIC SLOANE
4 T 60,000 feet the flyer’s plane becomes his cell of life, its equipment almost as important as his own body. Outside the plane the cold of space is of instant-freeze intensity, much colder than any thickness of clothing could protect from. It is so thin that an exposed human’s body would cease to function. Blood would boil there at body temperature. Death from oxygen lack would occur quickly. Accordingly, the high-altitude plane has a cabin pumped with high-pressure air. Heated clothing is plugged into the plane’s power line. Read the rest of this entry »
Postal flyers Succeed Against Odds in “Bringing” Mail Through
AT NOON, May 15, 1918, four pilots stood beside their planes ready to take off on the first official attempt to carry mail by air. That day was the beginning of a thing that has spread, not only through the United States, but into all of North America. Since that day millions of dollars have been spent, planes have been wrecked, and pilots killed, but the air mail goes on and it stands today as one of the great affairs of the nation.

Sideways rocket makes crosswind
A rocket engine mounted on the side of a new car shows GM research engineers how it will react to any kind of crosswind.
The rocket’s thrust, from 50 to 200 pounds, can be accurately controlled, and the rocket can be mounted anywhere on the car. Instruments in the back seat record effect. Formerly, engineers drove a car through a blast from a propeller, but the quick passage was disadvantageous.
