Airport-Docks for New York
The hardest thing in aerial travel, nowadays, is not to fly, but to get quickly to and from the airport; especially in such cities as New York. An architect, Harry B. Brainerd, has worked out a solution in connection with the great docks which will be built for the new huge liners. Roofing over the docks, as shown, will afford landing space for airplanes; while the great covered docks will serve also as hangars for dirigibles, as shown in the central slip above. Passengers can transfer almost instantaneously from ship to plane, by using the elevators. Between the slips, the available dock space will be utilized by offices, factories and warehouses. The projected port is to be 1,025×1,700 feet, pier buildings 115′ wide, 200′ high.
Tiny Blimps Carry Flying Electric Signs
BILLBOARD blimps, carrying” flashing neon signs through the night sky above big cities, form the latest innovation in spectacular advertising. The aerial electric signs, developed and patented by Goodyear Rubber Co. experts, spell out sentences a word at a time like many of the big displays on New York’s Great White Way.
Ten lighting units, each approximately six feet high and four feet wide and formed of a maze of curving and zigzag neon tubes, are attached to the side of the semirigid dirigible before the take-off. An ingenious hooking arrangement permits them to be attached or removed in a few minutes. Each unit is capable of producing any number or any letter of the alphabet.
During the flight, an automatic mechar nism makes the proper contacts to spell out the desired words on the side of the blimp. Perforated tape, similar to that used in player pianos, runs through the switching mechanism, the perforations tripping mechanical fingers to make the electrical connections. The sign remains the same until the next series of perforations is encountered, flashing on another series of letters.
Four Novel Toys You Can Make With Rubber Balloons
These drawings show the construction of four novel toys made from circus balloons that will prove highly fascinating. Fill the balloon with hydrogen and attach to it a postcard bearing your name, and a request to return it from whatever point it falls to earth. Thus you can learn in what direction and how far it travels. Another balloon, equipped with a gondola will float in the air like a wartime captive dirigible. The aerial torpedo which zips up through the air is made by affixing fins to an air-filled balloon. The unique air boat cuts through the water under power of air exhaust from blown up balloon.
HOME EXPERIMENTS WITH HYDROGEN
by VERNON TRACEY
HYDROGEN, the lightest of chemical elements forms a very interesting field of experiment for the home chemist. It can be produced easily in several ways for experimental purposes; one of the most common of which consists of the action of sulphuric acid on zinc.
A flask into which is dropped a few grams of zinc scraps is fitted with a rubber stopper, thistle-tube and delivery-tube as shown in the photo. The thistle-tube is fitted into the stopper so the end will be about 1/8″ from the bottom of the flask. The end of the delivery-tube is near the top of the flask. Dilute sulphuric acid is poured down the thistle-funnel and hydrogen is produced when it comes in contact with the zinc. The top of the thistle-funnel is covered with a piece of glass to prevent the hydrogen from escaping. The hydrogen flows out through the delivery-tube and is collected in a bottle over the pneumatic trough.
Do Wild Radio Waves Cause Air Disasters?
Millions of horsepower of high-frequency electric energy, running “wild” in the air, may be the cause of mysterious disasters to aircraft, such as the loss of the Akron, the dirigible R-101, Knute Rockne’s airplane, and scores of others. How these amazing currents affect not only airplanes but your body, your home, and any objects that fail in tune with them, is explained in this unusual article on the unseen menace from the sky.
by BURTON MANFRED
THE radio experts of the United States Navy have recently completed a series of astounding experiments, experiments that prove far beyond the shadow of human error that there is a new menace in the sky. Hour after hour, day after day countless thousands of horsepower of high-frequency electric energy is being pumped into the air by great radio stations and other high-frequency machinery which has become a part of our civilization.
Only an infinitesimal speck of this prodigious output of energy is consumed by the radio receivers of the world. What happens to the rest? Does it become a wild and roving source of death and destruction or does it rush into the frigid voids of space never to return to the earth?
Seems like that would be a pretty slow rescue…
U.S. Navy Blimps Learn New Role for Sea Rescues
With the aid of new airship inventions, U. S. Navy blimps can now “anchor” ” 100 feet above the sea, and pick up ill sailors or victims of shipwreck. A circular disk called a “drogue,” dropped into the sea at the end of a cable, keeps the craft’s nose pointed steadily into the wind.
