THIS is not a pretty picture. It shows the design of a woman's dress photographed on her flesh by the flash of an atomic bomb. It was taken from Japanese motion pictures made in a first-aid station in Hiroshima, but only recently released. Why were these pictures withheld from the American public for a full year?

AT THE foot of a steep grade in the Allegheny Mountains a bunch of railroad men sat on their haunches in a semicircle the other day looking dubiously at a spanking new Diesel-electric locomotive. The engineer in the cab proposed to pull a long string of passenger cars over the ridge ahead without “double-shotting”—without a helping locomotive.

A number of rocket projectiles like the stub-winged one above (inset) are being built for the Army to gather data on cosmic rays and other little-known radiations. Carrying instruments to ultra-stratospheric levels, they will supplement findings made by the B-29 Flying Laboratory at lower altitudes.

BIGGEST BOMBER. The Consolidated XB-36, world's largest land-based airplane, is shown above with a B-29 Superfortress, which used to be a monster in its own right. The war-born giant made its first test flight last August and, in the Army phrase, "exceeded expectations."

PILOTS now can learn how to fly loops entirely by instrument in an earth-bound cockpit that doesn’t budge an inch. The new electronic Dehmel flight trainer, produced by CurtissWright, can imitate—on instruments—the flying characteristics of anything from a small personal plane to a four-engined transport.

CAA RECORDS ascribe more than half of the deaths in private flying to the pilots’ failure to recognize an approaching stall. Hope for reducing the rate of such fatalities lies in the Safety Flight Company’s new “Stall Warning Indicator.” This CAA-approved device (below) is mounted on the leading edge of a plane’s wing (see diagrams) and when the stall point nears it flashes a light and sounds a horn in the cockpit to alert the negligent flier.

The gap between radar and walkie-talkie has been bridged by Westinghouse’s new cesium-vapor “talking lamp.” The lamp picks up words from a mike (above) and transmits them secretly by infrared rays to a parabolic reflector. This receiver unscrambles the rays and reconverts them into clearly audible words at conversational speed.

REPRODUCING photographs in natural color, long a difficult and uncertain process, can now be done with great accuracy and without the use of cumbersome multiple filters. The new Variscope does the trick. Developed and perfected by C. H. BirchField, of New York City, and his son, Arthur, the same team that invented the Iriscope (for making color projections from black and white stills), the Variscope looks like a small transparent bull’s-eye.

Keeps Colors in Line. A resin-and-heat treatment of the printed outlines of pictures in children’s paint books, devised by Will H. Connelly, of Park Ridge, Ill., prevents water colors from running and marring the painting. In printing the pictures, resin is applied to the wet ink; then, under heat, the lines swell or puff up, forming slight barriers or dams between the sections of the drawing to keep colors separate.

NUCLEAR physics, the unpredictable baby of the sciences, is about 50 years old. For the first two thirds of its short life it crawled patiently along on all fours. Then, without bothering to walk, it started to run. Just where it’s running to, no one knows, but it has already revolutionized man’s conception of his universe without even stopping for breath.

Self-Adjusting Circuit Makes Transformers Safer

[no value]
WITH this circuit, you can make it safer for a young child to play with low voltage A.C. toys that require a stepdown transformer. If the child accidentally shorts the secondary, the risk of burning out the transformer is greatly reduced because the two 115-volt bulbs installed in the primary side limit the current.

A SIMPLE method of reversing an induction motor is illustrated in the accompanying diagram. It involves use of an ordinary four-way toggle switch, which is, in effect, a D.P.D.T. switch. Since the switch carries current only during the starting period, it need not be one having a heavy-duty rating.

WHILE on a recent visit to a farm, I came across a novel idea for a yard light and a supporting pole for the electric wires between the house and barn. The pole, about 8" in diameter at the base, had been cut so as to retain the first major fork of the original tree.

CLINTON E. CLARK
A RADIO "station" hardly bigger than a shoe box is an ideal rig in many respects. If you’ve just obtained your license, you can use it to get on the air at the cost of a few dollars and even fewer hours. On the other hand, if you’re an old timer operating a more elaborate phone transmitter, here’s a quick and inexpensive way to renew your acquaintance with the fast-fingered hams who keep the code bands clicking.

THIS lamp is especially useful in the shop because it can be quickly moved to any spot where light is needed and hung on the wall molding. Its portability is limited only by the length of cord and the location of electric outlets. Attach an arm to an upright piece, securing it with an angle brace, and screw a picture hook to the top for hanging on the molding.

EVEN a tractor can be “souped up.” Older farm machines, formerly limited to a road speed of five or six m.p.h., are now cruising highways at 12 to 15 m.p.h.— pushed by powered trailers. The trailer, with a passenger car rear axle driven through the power takeoff of the tractor, does the work while the tractor coasts in neutral.

IN CARD FILES at the editorial offices of Popular Science Monthly are hundreds of names, with addresses and telephone numbers. If we were going to write down a list of assets, these names certainly would be at the top. For they are the names of our friends, people all over the United States who help put out our magazine.
