I particularly like the cow on the second page. You can fill it up with milk and um… milk it.

LOCOMOTIVE

This locomotive is made for the boy who likes to build his own, for it comes “knocked down” packed in a box. It is assembled or taken apart by following instructions; and parts may be replaced. — Dorfan Co., Newark, New Jersey

High-Speed Facsimile
As many as 180,000 words of printed matter can be transmitted and recorded within one hour through a new high-speed facsimile system. Photos and diagrams also can be transmitted to any distant point and recorded without photographic, chemical or drying equipment. The system, developed by Western Union, uses either radio beams or communications wires as a means of transmission. The sending operator slips the printed material into a transparent cylinder and closes the endgate of the cylinder. This starts the cylinder spinning at 1800 revolutions per minute, and a photocell acting with a pin point of light scans the material. At the receiving end, needlelike instruments “print” a copy of the material on a dry recording paper. At the conclusion of the message an automatic signal causes a knife to cut the facsimile copy from the roll of dry recording paper.

LIVE PIGS SHIPPED IN BASKETS TO SAVE CARGO SPACE
In order to save space in shipping, small live pigs are being sent in baskets for long distances in south China. By placing them in the baskets, large numbers can be piled in a comparatively small space and the porkers can be handled like any inanimate units of merchandise.

Mechanical SUPER-BRAINS

Calculations in Higher Mathematics Performed by Complex Machinery

• FOR thousands of years after arithmetic and geometry had been worked out, these forms of mathematics were sufficient for most purposes of even learned men. However, when science became complex, and especially in the development of modern astronomy, it was apparent that new methods of calculation were needed. Two hundred and fifty years ago, Sir Isaac Newton and Wilhelm Leibnitz, working independently, devised methods of procedure which have been refined into what is now called, for short, calculus. Without this, modern science and engineering could never have reached their present development.

Inflated Arm Bands Cut Hazards of Swimming Lessons
THE hazards and effort involved in learning to swim are greatly reduced by means of the novel inflated arm bands, or “side wings,” recently introduced at Los Angeles beaches. Wearing these wings, the novice can venture into deep water without fear and can rest when exhausted.

When pumped up with air, the wings, which are made of rubber and fitted on the arms near the shoulders, enable the swimmer to keep his head above water while he perfects his strokes, thus simplifying the ordeal considerably.

Each arm band is provided with valves for inflation. When blown up the wings are extremely light and in no way interfere with circulation of the blood.

Patients In Revolving Hospital Have Sunny Rooms All Day
SUNLIGHT exposure during the entire course of the day is provided patients in a revolving hospital ward at the Institute of Actinology in Vallauris-Le-Cannet, France. Patients afflicted with diseases requiring ample dosages of sunlight are treated at this hospital, declared to be the most up-to-date in France. As the sun rises in the morning, all rooms face the east, and then as the sun crosses the sky, the ward revolves on its axis to follow its course.

Machine Shows Cartoons Without Screen
A NEW idea in motion pictures machines has just been developed. by Max Fleischer, the well-known movie cartoonist. The mechanism, shown above, consists of a large cylinder on which are attached cartoons of the various comic characters, and a large rotating shutter with two narrow slits on either side of it.

As the cylinder is rotated, the shutter revolves in unison, so that by standing at a point in front of the machine and looking at the right portion of the shutter, animated cartoons of amazingly smooth action can be viewed.

In contradistinction to the common movie projector, Mr. Fleischer’s machine has no intermittent action, and the big wheel never stops but revolves continuously. A full picture with smooth flickerless action is the result.

Magic-Makers of the Radio Stations

Sound engineers combine ingenuity and science to make up their bag of tricks.

THEY were dissecting the brain of Nicolai Lenin—on the radio. It was a news broadcast of the achievement of the Soviet Brain Institute in Moscow which had developed a means of slicing brain tissue into thousands of paper-thin fragments for scientific study.

“Give us the sound of a brain being sliced,” came the bizarre order to the sound effects department of the Columbia Broadcasting System.

How a jet engine runs on its “nerves”
Auxiliary “nerve center” of a jet’s engine, this complex gearbox transmits the power that runs oil and fuel pumps, generators, and other vital accessories. To produce this intricate unit for J-40 engines, Westinghouse looks to Lycoming for precision production.

From a jet’s mighty engine, these precision gears “take off” power and pass it along to vital accessory equipment at the specific rate required by each different unit. As many as 30 separate gears … as many as 2500 separate machining and assembly operations … go into this gearbox so essential to safe, efficient operation of a jet. And for this tremendously complex production, Westinghouse depends on Lycoming.

Lycoming stands ready to assist you, too. Whether you have “just an idea” that needs development, a problem in the blueprint stage, or a finished metal product that needs precise, speedy fabrication … you can depend on Lycoming’s long-tested ability to meet the most exacting and diverse industrial or military requirements. Whatever your problem—look to Lycoming!

Lycoming’s 2-1/2 million feet of floor space, its more than 6,000 machine tools, and its wealth of creative engineering ability stand ready to serve your needs.
