Down at the bottom of this page is what is called the “masthead.” For some reason, magazine staffs are full of what seem to be fictional names. In fact, William Saroyan once had a character in a play intone the whole masthead of Time. Popular Science Monthly, too, has its share of unusual people, some of whom have matching names.

As I understand it, the energy in the atomic bomb is similar to the energy contained in most other dry explosives such as black powder, dynamite, TNT, etc.... We use compression chambers for gas, acetylene, and air. We dam water, and create huge reservoirs of potential power.

RISE AND FALL OF A CHEMICAL EMPIRE
Why Air Blows That Smashed Synthetic Oil Industry Caused Mighty Nazi War Machine to Grind to a Halt
[no value]

VOLTA TORREY
NAZI Germany was a chemical empire that rose swiftly, fell suddenly. Its history has been written now by scientists. Civilian chemists and engineers of the U. S. Strategic Bombing Survey have unraveled this unprecedented empire’s inside story from secret German records, interviews with German authorities, and extensive surveys of the bombed-out plants and laboratories of the Reich’s oil, chemical, rubber, and explosives industries.

BALLOON “scouts” in the stratosphere helped keep U. S. Army and Navy planes flying during the war in all but the foulest weather conditions. One reason why missions were accomplished in anything less than a typhoon or a black fog was that service meteorologists knew more about the weather than ever before.

DEVON FRANCIS
FOR some men in the U. S. Navy, V-J Day was just another date on the calendar. Their war will go on for another two years, maybe longer, because they are assigned to sweeping murky ocean water clear of mines. During six years of war, tens of thousands of explosive containers were sown in the waters of the Seven Seas, by both the Axis and the United Nations, to tear open the hulls of enemy ships and send them to the bottom.

THIS little jet-propulsion engine—it’s only 9½ inches in diameter and weighs only 145 pounds for all its 275 pounds of thrust—was designed by Westinghouse engineers to power a Navy “buzzless” buzz bomb. Its turbine spins 34,000 times a minute, and its jet stream delivers 275 horsepower at 375 miles an hour.

ALDEN P. ARMAGNAC
GEM diamonds now appearing on the market have more brilliance and fire than ever, as a result of the first major improvement in the ancient art of diamond cutting in 300 years. The more sides or facets that are cut in a diamond, up to a certain point, the greater its over-all brilliance—its total reflecting power.

ALL the rays of sunshine at the seashore now can be delivered almost anywhere. Simulating sunlight requires only a few thousand foot-candles of ordinary light, but more invisible than visible rays are needed to synthesize sunshine. It has been done, however, with the rays of 423 lamps, of six types, in the new “sunshine ceiling.”

IF HE did not have so many other claims to fame, Thomas Jefferson might today be celebrated as one of our greatest inventors. His mind fairly overflowed with mechanical ideas, and the fruit of his creativeness is everywhere in evidence. Had he not been so preoccupied with an even bigger job—creating a new government for a new nation— he might well have been the great scientist of his age.

PLANE PARTS FEED BIRDS in the rig at left. A droppable fuel tank, now surplus, was modified by George H. Smith, of Sauquoit, N. Y., into a dry-mash chicken feeder of 140-lb. capacity. Below, the plastic tank is shown cut into three parts. The smallest section, which serves as a spreader, was inverted in a metal bushel basket set on legs.

ALCOHOL ... HANDY MAN OF CHEMISTRY AND INDUSTRY
These Experiments Show Chemical Traits of a Useful Liquid
[no value]
[no value]
KENNETH M. SWEZEY
TO A CHEMIST, the word alcohol indicates a great family of organic compounds. Such combinations already have been made by the hundreds, and thousands more are theoretically possible. Methanol (wood alcohol), ethanol (grain alcohol), isopropanol (rubbing alcohol), and glycerol (glycerine) are a few of the common ones.

SIGHTING along a mark on the work rarely produces accurate cutting on the circular saw, especially when the work is marked on an edge as above. But a line painted on the table, in front of and aligned with the saw blade, will show exactly where the kerf will come.

To DRILL out a stud broken off beneath the surface of a workpiece is troublesome, and it may necessitate rethreading the hole. With a large-diameter stud broken not far from the surface, you can sometimes add weld metal to the top of the stud, and then, after a head has been welded to the extension, unscrew the stud with a wrench.

GEORGE I. SMITH
WITH a little scrap lumber, some stiff wire, and a piece of mosquito netting, you can make an effective filter for a warm-air heating register. When you remove and clean it every three or four weeks you will see how much dirt it holds back. Cut the wire into lengths equal to the distance between joists minus the thickness of the detachable frame member.

Long Stair Stringer Is Strongly Spliced with Lap Joint

J. MODROCH
IF YOU find it necessary to splice a housed stair stringer because of a lumber shortage, you can do a strong, neat job by lap-jointing the pieces on a line with one of the tread grooves, as shown at right. Where the customary stringer thickness of ¾" and groove depth of ⅜%" are employed, the thickness of the face wing (the undercut end of the piece at the bottom of the photo) must be slightly greater than the thickness of the back wing (on the other piece) to avoid cutting away the bottom of the riser groove in the face wing.

The clock now runs as quietly as it did when new.

PAPERING the outside walls of your coal bin with heavy wrapping paper will help to prevent the spread of coal dust through the lower part of the house. Thumbtack large sheets of used paper liberally over the outside planking of the bin. Make sure that all sheets overlap and that no spaces are left between them.

P. W.
HOME craftsmen who have found it difficult to obtain springs of the right materials or dimensions can wind their own even without a lathe. Procure a rod slightly smaller than the desired diameter and drill a starting hole near one end. Pass an end of the spring wire through this hole and clamp the rod between two blocks of soft wood mounted in a vise as shown.

FRANK SHORE
EVERY typist has had the experience of spoiling the appearance of a page by overrunning the lower margin. A backing sheet, numbered to show how many lines remain, can end this nuisance. Mark off the spaces in the margin and insert with the paper so that the marked portion extends about ¼" along one side.
