Robot Production Line Makes 3 Radios a Minute (Apr, 1948)

Robot Production Line Makes 3 Radios a Minute

THE so-called “printed” radio sets are still new on the American scene, but they are rapidly becoming common items in England. A new factory near London is using a robot machine (above) which takes the plastic molding in one end and delivers the printed circuits from the other end at the rate of three a minute. It would take about 2,000 workers to do the same job by hand.

“Hellos” by the Millions (Jan, 1934)

“Hellos” by the Millions

RECENT figures compiled by the Bell System show that there is more than 145 million miles of telephone wire in the world, or enough to reach from the Sun out past the planet Mars; and about 60% of it is in the United States, where it was used for more than twenty-seven billion conversations over the wire last year. (At three minutes each, this is 154,000 years of talk.) That is, every man, woman and child in the United States made 220 calls; or, rather, leaving out those who can not use the telephone, there was an average of only about one call a day. In the use of the telegraph, the United States is a shade less pre-eminent; it has only a third of the world’s 6,773,500 miles of wire.

More Telephone Service for more people

From The 1946 Annual Report of the American Telephone and Telegraph Company.

1. In no year since the telephone was invented was there such a remarkable increase in the amount of telephone service furnished to the American people as in 1946. The net gain in the number of Bell telephones was 3,264,000, or more than twice the gain for any previous year. Additional telephones were installed at a rate averaging more than 25 a minute every working day.

Tank Maneuvers Controlled by Radio (Dec, 1930)

Tank Maneuvers Controlled by Radio

Developments in the mechanization of the army is the installation of radios in tanks for the transmission and receipt of orders. Control of tanks in action, since they were first introduced by the British during the World war, has been at once an important and difficult task, hitherto performed by officers who walked beside the tank and signalled with flags—a duty both dangerous and unsatisfactory.

Phone Uses Light Sockets (Feb, 1937)

Phone Uses Light Sockets

A NOVEL telephone which a person can plug into the nearest electric light socket to talk with another person plugging a similar telephone into a similar outlet near at hand has been developed by a New York City manufacturer. It was demonstrated at the New York Museum of Science and Industry by Dr. O. H. Caldwell, a trustee of the museum.

NEW TELEPHONIC DEVICE KEEPS HANDS FREE (Jan, 1929)

NEW TELEPHONIC DEVICE KEEPS HANDS FREE

MR. GEORGE TANKARD is shown below with his new invention that is designed with an eye to speeding up the efficiency of a busy man. This invention is balanced on the shoulder by the form fitting holder. The receiver is placed in the holder and then adjusted to the shoulder so that the ear gets the best results. It is interesting to note that this device has been produced in London, where the American type of speed efficiency has been taking a very strong hold in the last few years.

COMMUNICATIONS are being revolutionized faster than you think. The humming wires beside the highways already are rivaled by new systems, capable of transmitting more spoken or written words and more still or moving pictures from coast to coast. The difference between these new systems and those of the past is as great as that between oxcarts and stratoliners.

Static from the Stars (Jan, 1948)

Static from the Stars

Because a radio ham heard strange sky noises, we may get better FM and television—and learn more about our universe.

By Herbert Yahraes

Drawings by Ray Pioch WHEN young Grote Reber was a high school sophomore, he operated 9GFZ in Wheaton, Ill., and tacked so many recognition—QSL—cards to his bedroom walls that the plaster cracked and his parents cracked down. When not communicating with El Paso, Arequipa, Capetown, Prague, and other points, he designed equipment to communicate with them even better. Nobody who knew him then will be surprised to learn that he is still in radio—listening not to the chatter of hams, but to mysterious and bothersome radio waves that come from the heart of the Milky Way.

Radio Living Room of Tomorrow (Aug, 1939)

Radio Living Room of Tomorrow

Simple in arrangement, and soft in color because of television, the suggested “radio living room of tomorrow” at the New York World’s Fair is open to visitors, who are permitted to inspect the various sight, sound and facsimile facilities while they are in operation.
