Rifle shoots infrared ray
You can stand in front of this target rifle without fear of being hurt. Instead of bullets, it shoots a beam of light. Both rifle and its special target are powered by flashlight batteries. A bull’s-eye is scored when a pulse of infrared light strikes the center of the target and activates a flashing light and a bell. The rifle is manufactured by Infrared Industries, Waltham, Mass., makers of electronic devices for the government’s missile and satellite programs.
Luxury Side Car Is Streamlined
DRESSED up in modern streamlining, the new motorcycle side car which is making its appearance on European highways is making a strong bid for popularity among motorcycle enthusiasts.
The latest side car of streamline design has a windscreen which extends well over the passenger’s head, with a head rest in the rear built up to follow the sweep of the air stream. Along the bottom edge of the screen is an adjustable ventilator which provides a flow of air to all parts of the car.
The blunt nose of the earlier model side car has been replaced by long sweeping curves.
How Mechanical SPIDERS SPIN Bay Bridge Cables
by C. W. GEIGER
This article describes in simple language how a wire long enough to encircle the world three times is carried back and forth across San Francisco Bay by traveling wheels to spin the suspension cables of the world’s longest structure, the mammoth San Francisco-Oakland Bay Bridge.
BY FAR the most spectacular operation in the construction of a suspension bridge is the spinning of the mighty cables which loop gracefully from tower to tower, supporting a roadway hung far below. How are these mile-long cables, each weighing 9,500 tons and containing 17,464 strands of steel, being stretched from tower to tower for the San Francisco-Oakland Bay suspension bridge?
Trapeze, Shower Bath, Punching Bag Feature Gym Bed
A COMPLETELY equipped gymnasium, a turkish bath, a shower bathâ€”all these have been combined into a single colonial-style bed by J. S. Embree, Los Angeles inventor.
The bed is a “four-poster” with an awning top. Parallel bars are set between the end posts, and they are removable to be used across the top of the bed as trapezes. A punching bag-hook hangs from the top for arm and torso exercise; using a suspended swing as a seat, a small portable pedaling device furnishes exercise for the legs.
A shower attachment permits either a shower or a turkish bath after exercise. Music to accompany exercises comes from a radio set in the head of the bed.
Streamline Beauties Lure Travelers to Rails
ROLLING along railways of the world at greater than mile-a-minute speeds, streamlined trains are conquering time and space in an attempt to keep the traveling public from deserting the rails for airplanes and motor buses.
Three choices have been offered to the jury of travelersâ€”the ordinary steam train running on faster schedules, the beautiful Diesel-powered streamliner, and the light weight steam streamliner in its gleaming new dress of chromium and brass. A fourth contestant recently entered the pictureâ€”a turbine-drive steam locomotive that may surpass all others in speed, safety, and comfort.
Now we know where they got the idea for Hellraiser from.
“Beauty Micrometer” Analyzes Facial Flaws for Makeup
RECENTLY perfected by Max Factor, one of Hollywood’s most famous beauty experts, a new instrument, designed to aid makeup men, accurately registers actors’ facial measurements and discloses which features should be reduced or enhanced in the makeup process.
Flaws almost invisible to the ordinary eye become glaring distortions when thrown upon the screen in highly magnified images; but Factor’s “beauty micrometer” reveals the defects.
Motor Unicycle Proves Fast, Safe
A SPECTACULAR demonstration of unicycle operation was given in Los Angeles recently when Walter Nilsson, California inventor, drove his specially constructed machine 18 miles per hour in second gear without the aid of a pneumatic tire.
His unicycle consists of a single outer wheel driven by an inner wheel held in a stationary frame and powered by a one-cylinder motor. The engine is mounted motorcycle fashion between the rider’s legs. Steering is accomplished by means of a secret device which tilts the outer wheel while permitting the rider to remain upright.
With the arrival of a pneumatic tire, Nilsson expects to be able to attain 100 miles per hour.
Filling in the Hudson to Rebuild New York
by ALFRED ALBELLI
PLUG up the Hudson river at both ends of Manhattan . . . divert that body of water into the Harlem river so that it might flow out into the East river and down to the Atlantic ocean . . . pump out the water from the area of the Hudson which has been dammed off … fill in that space . . . ultimately connecting the Island of Manhattan with the mainland of New Jersey . . . and you have the world’s eighth wonderâ€”the reconstruction of Manhattan!
That is the essence of the plan proposed by Norman Sper, noted publicist and engineering scholar. It is calculated to solve New York City’s traffic and housing problems, which are threatening to devour the city’s civilization like a Frankenstein monster.
WORLDS LARGEST PISTOL?
IF this isn’t the biggest pistol in the world, we’d just as soon not meet the champ. R. G. Wilson of Fulton, Mich., turns out these giant .45-70 copies of the Wild West’s famed .45-cal-iber Colt single-action Peacemaker, and at $250 each he can’t make ‘em fast enough to meet the demand.
