THE 4.2 mortar, nicknamed the “goon gun,” is a Cinderella among American weapons. Developed by the Chemical Warfare Service to hurl gas, it has blossomed out as a light and versatile adjunct to the artillery. It routs the enemy with stinging white phosphorous, blinds him with smoke, and pelts him with high explosives.

TWO men sat at a velvet-covered table rolling tiny little white balls back and forth. They watched intently as the pellets rolled. Now and then they picked up one to look closely at it; then they went on rolling them back and forth. No game of marbles this, as you could tell by the seriousness of the two men.

CARL DREHER
ELECTRONICS is not an industry in itself, any more than chemistry or physics. It is a technique, a way of doing things in a lot of industries. It did, however, create one industry—radio—and the requirements of that industry resulted in the invention of the vacuum tube.

A MORTAR BOMB developed by J. Wauters, of Brussels, has a tail, containing the propellant, that drops off after the bomb leaves the muzzle. In this way the center of gravity is moved forward to make the bomb’s flight more accurate. A loose ring around the bomb’s waist fits snugly into the bore to conserve the charge’s pressure.

A MOBILE 24-MAN SHOWER, developed at the Quartermaster Replacement Training Center, Camp Lee, Va., has now been adopted by all branches of the service. The unit consists of a gas-driven 3,000-gallonan-hour pump, a collapsible frame for the 24 shower heads, and a heater that warms the water to about 105 degrees F. Trailer-mounted, the unit can be compactly folded for transport by air.

Name Your Job... The A-20 Does It
REVERSING THE TREND TOWARD ONE-PURPOSE PLANES, THE HAVOC HAS PROVED THE VALUE OF VERSATILITY
AN ALL-AROUND PLANE, THE HAVOC TAKES ON MORE JOBS ON MORE FRONTS THAN ANY OTHER AMERICAN-BUILT SHIP

JOHN E. LODGE
THIS is the story of a resurrected airplane—a ship that was taken off the stag line of possible operational equipment to become one of the most versatile craft of the war and the undisputed leader of its class. Its manufacturer’s serial is the Douglas DB7; the British bought it as the Boston and renamed it the Havoc; our Army Air Forces list it as either the A-20 or P-70, depending on application; the Nazis flatter it with such cognomens as Nachtteufel (night devil).

Careful study by Paramount researchers, backed by the painstaking work of studio set builders, provided this realistic background for a dramatic sequence in Cecil B. DeMille’s production of “The Story of Dr. Wassell,” which tells the heroic true-life story of the medical missionary who won world-wide fame by evacuating wounded U. S. Navy personnel from Java after the Japanese invasion.

ABRASIVE DISKS
ABRASIVE DISKS of Metalite Fibre Combination are made up of aluminum oxide grains and cotton drill glued to a vulcanized fiber. They are used for polishing metal surfaces before covering them with paint or lacquer, and are effective for removing hard enamel coatings as well as lighter metal finishes. Made by Behr-Manning, Troy, N. Y.

ANGLE-HEAD
ANGLE-HEAD soldering iron goes places and does things that are difficult with the ordinary type. In a tight spot, its extendable tip, running through the center of the barrel, permits the user to solder electrical connections without burning the insulation on adjacent wires. The scientifically balanced angle-head lessens fatigue by allowing the operator to hold the iron with ease. It is made by the Kelnor Manufacturing Co., San Francisco.

PRECISION-CUT CRYSTALS
PRECISION-CUT CRYSTALS used in radio, sound-detecting, and locating devices are given extreme accuracy by the Clark Replacement Orientation Table, which is said to eliminate the necessity for much of the expert manpower formerly required for making corrections. The table is adaptable to any quartz-cutting saw, and is designed to minimize wear from vibration.

METAL-SHRINKING
METAL-SHRINKING process, ordinarily tedious, is speeded and simplified by a compact, portable, hand-operated machine made by C-B Tool Company, Lancaster, Pa. This shrinker handles metals .016 to .051 inch thick, shrinks angles to a three-inch radius, and will work angle stock up to one inch wide. There is a combined stretching and shrinking process involved in bending angle stock, for the outside of the curve must of necessity be longer than the inside. The device weighs 12 pounds.

ACTION-BACK CLOTHING
ACTION-BACK CLOTHING has been designed for energetic men of the postwar United States. The model coat at the right, featuring a panel back, is the idea of the Merchant Tailors and Designers Association of America. It is a new version that is intended to permit free arm movement and still lie perfectly flat, something that has often been lacking in earlier clothing of a similar type. As will be seen in the photo, the panel is attached to the coat proper only at the shoulders and the waist. Another feature in the clothing designed for after the war is the vest shown in the photo below. A slide-fastener arrangement at each side of the vest allows a 3" adjustment in width at the waistband. This adjustment can be made easily by the wearer without removing the vest. It looks like an excellent idea for the time when rationing is at an end and hearty eating is again customary

REALLY A HARD NUT TO CRACK
REALLY A HARD NUT TO CRACK, the Brazilian babassu nevertheless yields valuable oils widely used in making soap and margarine and in cooking. Natives of Brazil painstakingly crack this huge palm nut with an ax and a hardwood club in a way similar to that employed by the young lady in the photo, sometimes using 100 blows. When an easy, mechanical method of cracking them is invented, babassus are expected to be a big money crop. In addition to their oils, they have shells that burn with intense heat, can be made into charcoal and coke, and yield important chemicals when distilled

[no value]
C. W. B.
IN COPYING, enlarging, and reducing patterns, drawings, maps, and the like, the diagonal method is often found easier and quicker than the more familiar square-up method. The diagonal method is more efficient in that its diagonal, vertical, and horizontal lines intersect and are tangent to a greater number of curved and irregular lines in the original; thus coordinates form key locations more frequently, making it easier to transfer points from the original to the copy.

WORKING GEAR RATIOS can be shown on a lathe having change gears if a small indicator cut from thin brass, copper, or tin-can stock is mounted on the threading plate, as at right. If the metal is too brittle to bend fairly flat so a back section can be inserted between the plate and the lathe, two short pieces may be riveted together.

WHEN your bicycle begins to pedal hard because of wear on the sprocket teeth caused by the chain, you can put off installing a new sprocket for some time by grinding off the rough humps so that the chain will again act smoothly and quietly. If you have a small portable grinder or a flexible-shaft tool, the sprocket need not be removed from the bicycle while grinding the teeth to a free-running outline.
