Device Dries Wash In 3 Minutes
AN ELECTRICAL clothes drier using centrifugal force is capable of rough drying the family laundry in three minutes. The dryer plugs in on any light circuit, and is small enough to fit in any out-of-the-way corner.
The clothes to be dried are suspended by a net inside a rotating cylinder. As the rotation casts the water off, air currents are drawn through the clothes to hasten the process through evaporation. A waste pipe draws off the excess water.
The dryer is much easier on clothes than wringing, as well as being much faster. It was developed in Germany.
NBC Proves Television Practical
TRANSMITTING television movies across Metropolitan New York the National Broadcasting Company recently proved that this new science had definitely left the laboratory and was ready to be offered to the American public. More than two hundred spectators gathered around television receivers set up in the sixty-second floor of the RCA Building in New York City to watch the thrilling broadcast, which included both live talent and movies.
The program originated in the television studios of the National Broadcasting Company and was transmitted over coaxial cable to the television sending apparatus located atop the Empire State Building. Here a transmitter operating on 343-line definition sent the television pictures out over the air
to be picked up by the receivers located high up in the RCA Building.
Although the broadcast exceeded the wildest expectations of the newspaper representatives who attended the demonstration it will still be several years before television will be offered to the public due to complications which must be remedied. A standard line definition must be decided upon and permission of the Federal Communications Commission secured for commercial broadcasting.
Pet Shops Wrap Fish in Transparent Bags
Customers of pet shops selling goldfish and various tropical species can watch their purchases swim around as they are carried to home aquariums in novel transparent bags just introduced. Made of waterproof, transparent cellulose material, in various sizes, the fish bags have reenforced handles for ease in carrying. When the
container has been partially filled with water, the fish are transferred to it from the store tank..
Plastic Liner Protects Shirt Pocket From Damage by Pencils
If you carry sev-eral sharpened pencils in a shirt pocket, this easily made plastic liner can be used to protect the shirt from being soiled or damaged by the pencils. Just cut a strip of sheet plastic to fit snugly in the pocket, heat the plastic and bend it double, leaving a space the thickness of a pencil between the plastic folds. Then bend down one end of the plastic to slip over the edge of the pocket.

Wow, $109 dollars in 1973 for a crappy digital clock radio.
Digits Make It Big in Clocks
By Len Buckwalter
ONCE it was the hula-hoop. Then home calculators. Now it’s digital clocks that we’re flipping over. More than half of all clocks sold in this country nowadays come without round face and hands. Instead, a window displays time in changing numbers that resemble those seen on computers.
Wow that’s a lot of deflection on those rotors in the top picture.
I think this is actually only the first U.S. helicopter.
Helicopter Flown Successfully
WHAT is claimed to be the first successfully controlled vertical flight in a heavier-than-air machine was made recently by Ivor Sikorsky, prominent aeronautical engineer, at Bridgeport, Conn., in his new helicopter. Powered by a seventy-horsepower engine and equipped with variable-pitch rotor blades, the craft moved straight up from the ground for thirty feet, circled the field, and then settled vertically to the ground. Small rotor blades mounted on the bare fuselage of the craft act as elevators and rudder. Sikorsky is shown at the controls of the helicopter in the photographs.
Well, actually the Guinness Book of Superlatives, I’m not sure when it was changed.
The Most of Everything
There’s a book out for people who want to know the largest, smallest, fastest, richest, hottest, coldest, oldest and mostest.
ARGUING about which is the mostest of anything, like the highest point in Our State or the longest bone in the human body, just seems to go with beer. Some say pretzels go better, while another body of expert opinion favors cheese and raw onions. But arguing about the mostest rates high as a diversion of malt brew enthusiasts, and that is no doubt why the ancient house of Arthur Guinness Son, Ltd., Dublin, has published The Guinness Book Of Superlatives.
GLASS FIBERS finer than human hair make up the chief part of an optical instrument that can see around corners. The fibers are aligned in a rope bundle. By looking along the axis of the fibers, you can see an image at the other end, no matter how the rope is looped or twisted. Doctors may use it in internal examinations of the human body. Scientists could observe radioactive materials shielded behind lead walls and engineers could use it to investigate concealed parts of complex machinery. Known as the Fibrescope, it was developed by Dr. H. H. Hopkins and a 27-year-old Punjabi, Dr. Narinder Singh Kapany, at the Imperial College of Science in London. The simple instrument may replace expensive optical systems which are bulky and inflexible.
Electric Cannon Uses No Gunpowder
SILENT guns sending their whistling messengers of death into the sky at speeds far beyond those now attained by powder-driven shells seem likely for the next war, using for propulsion magnetic fields so powerful that when they are short-circuited they produce miniature earthquakes.
Dr. Kapitza, F. R. S., working at the Cavendish laboratory of Cambridge University, England, in his attempts to disrupt the atom has produced magnetic fields so powerful that they “explode” the coils that produce them. This man has finally revealed the secret of the magnetic gun so long anticipated by ballistic experts. Dr. Kapitza accomplishes the electric firing of a shell by short-circuiting powerful dynamos for periods of one one-hundredth of a second.
Plans are being made to harness mankind’s oldest and cheapest source of power for industry by means of huge aerogenerators.
By Frank Tinsley
THE next few years may see a decided change in the landscape of our country. In certain strategic places which promise a constant, strong wind such as mountain passes, will grow strange structures resembling the Martian machines of H. G. Wells. But these will be instruments of construction, rather than destruction â€”tall, steel towers supporting fans to convert wind energy into electrical power.
