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.
Egg Assembly Line Separates Yolks From Whites
AMONG THINGS MACHINES CAN DO better than people are breaking eggs and separating the yolks from the whites. One machine also washes and sterilizes the shells before they are broken. The contents are dropped into separating cups and the empty shells are carried away on a conveyor. The cups carry the whites and yolks
under an ultraviolet light which makes certain bacteria appear fluorescent. The machine operator removes inedible eggs or broken yolks. Whites flow over a shallow inspection tray and into a collection pail. Yolks are separated electronically for light or dark color above a divided chute. Cups are washed before receiving another egg.
“Fill’er Up with Cold Air!”
Texas gas stations are delighting motorists with a new kind of free air. When a car stops for gas, a nozzle fixed to an air conditioner is poked in the window. Station attendants say temperature inside the car drops as much as 20 degrees in two minutes.
Print Photographs in COLOR on METAL Gifts
YOU can inject a personal note into your Christmas gifts this year by placing on them photographs of yourself, of friends or of scenes you have snapped with your camera. Any smooth surface can be treated in this way, including metal, wood, glass or composition. The pictures are permanent, can be made in any color, and have the shiny, glass-like appearance of glazed enamel.
Dig That Crazy Ribbon!
UP IN Greenwich, Conn., the night air was shattered by the 60-db roar of an African lion. Frantic phone calls to police headquarters brought a safari on the run, armed with ropes, nets and high-powered rifles. After carefully surrounding the wooded residential area where the beast had been reported, the police cautiously closed in.
But instead of a prowling predator, they bagged â€”of all thingsâ€”a loudspeaker. It seems that there was a party in the neighborhood, and the hostâ€”a tape recording fanâ€”had hidden a strong-muscled speaker in the bushes outside. As the party was slowing down, he played some tapes he had made at the zoo, “just to pep things up!” That’s what he told the judgeâ€”which goes to show that, while most uses for tape recorders in science and industry are pretty serious, tape has its zanier moments as well.
Defense Gun Hurls Balls of Fire
A GUN which shoots eight streaking balls of fire in rapid succession is now being tested as a possible anti-aircraft gun to set fire to enemy planes during wartime.
The gun is built on a “Roman Candle” principle, each ball being separately ignited from a battery as the trigger is pulled. A metal funnel on the end protects the operator from flying embers cast by the imperfect powder balls now being used.
Craftsman Earns Living Making Gold and Silver Telephones
PORTER BLANCHARD, Los Angeles inventor, takes a great delight in beautifying the more simple household articles found in every home and has even gone so far as to produce telephones from silver and gold at a total cost of $500 each.
The phones, of the ordinary French type are entirely taken apart and dipped into an electroplating solution. Current is passed through the solution to plate the various telephone parts.
Several times during the process, the parts are removed and polished to a glossy smooth finish to insure an even result. The plating is about the thickness of paper.
