New Cable Conquers Congestion (Sep, 1939)

New Cable Conquers Congestion

IMAGINE a city street with a thousand rows of telephone poles, each holding aloft sixty wires!

Of course such a street would look more like a bad dream than any kind of a thoroughfare, but without the modern lead-covered cable that’s exactly what half the streets in most of our larger cities would look like. The picture at the left showing lower Broadway, in New York City, in the ’80s gives a slight hint of what a city street would look like without present day cables, developed in the past four decades by telephone engineers.

Photograph Records Both Portrait and Voice (Sep, 1934)

Photograph Records Both Portrait and Voice
RECORDS of both the portrait and voice of subjects are the latest novelty photographs on the market in Germany.

The paper on which the photograph is printed is also grooved for phonograph recording. After the photograph is taken and the print is made, the subject can transcribe his voice on the photograph without damaging the picture.

The novelty photographs are especially valuable for sending “talking pictures” to friends and relatives in distant lands and cities. The photographs are of average size and carry a voice recording of approximately three minutes’ duration. The center is punched so that the record can be used on any phonograph.

The New IBM Electronic Data Processing Machines (May, 1953)

Over 2000 multiplications per second!!! What could we ever do with such power?

The New IBM Electronic Data Processing Machines

For Science… Industry… Defense

Combining the great storage capacities and speeds of cathode ray tubes, magnetic drums, and magnetic tapes with the tremendous computing speeds of electronic tubes, IBM engineers and scientists have produced in these machines the most flexible and most productive calculating unit ever marketed.

Here is a computer that can add and subtract 16,666 times a second . . . that can multiply and divide 2,192 times a second . . . and can recall factors from storage, or “memory,” in as little as 12 millionths of a second.

Bell Ad: Very Early Routing Tables (Mar, 1955)

How your telephone call asks directions… and gets quick answers

When the Bell System’s latest dial equipment receives orders to connect your telephone with another in a distant city, it must find-quickly and automatically—the best route.

Route information is supplied in code—as holes punched on steel cards. When a call comes in, the dial system selects the appropriate card, then reads it by means of light beams and photo-transistors. Should the preferred route be in use the system looks up an alternate route.

Portable Army Radio Tested (Nov, 1937)

It looks like you should be able to wind up that key in his back and make him march.

Portable Army Radio Tested
A PORTABLE field radio transmitting and receiving set that operates while strapped to a soldier’s back was satisfactorily tested by the Royal Corps of Signals at Alder-shot, England. The device features a special loop-type antenna, standard earphones and a hand microphone. The power supply unit is self-contained.

heroes must not lisp! (Dec, 1930)

heroes must not lisp!
“My thweet” lisped from the screen would mar the star’s romantic appeal. But that is something you don’t hear in the theatres which have Western Electric talking picture equipment.

To reproduce the letter ‘S’ was but one of many difficulties in the way of giving you talking pictures at their best. Western Electric was able to solve these problems by reason of its 50 years’ experience in making Bell telephones and other voice transmission apparatus.

All over this country, and indeed the world, a discriminating public flocks to Western Electric equipped theatres — one more proof of this company’s leadership in sound.

How soon will you be able to see over the phone? (Aug, 1956)

There is something humorous about a rotary video phone.

CREATING A NEW WORLD WITH ELECTRONICS
How soon will you be able to see over the phone?

It may be sooner than you think. For the remarkable new Hughes tonotron—now used for high-fidelity transmission of maps and other navigational pictures to ships and aircraft—will make possible “face-to-face” telephone calls to and from your office or home.

The tonotron is only one example of Hughes Products leadership in research and development of electron tubes and related advances in electronics, such as transistors and diodes. It is with products like these that science will bring about the dynamic electronics era—in which you will have on-the-wall television, electronic control of factory production, and countless other marvels.

As one of the country’s largest electronics research and manufacturing firms, Hughes Products backs its semiconductors, cathode ray tubes, and industrial systems and controls with a long record of technical accomplishments. These include the “thinking” falcon air-to-air missile, and the self-directing Hughes Automatic Armament Control which is standard equipment on all Air Force interceptors.

Undoubtedly there is a time- and money-saving application of Hughes electronic products to your own business. A Hughes Products sales engineer will welcome the opportunity to work with your staff. Please write: Hughes Products, Los Angeles 45, California.

Giant Radio Tube Produced (Nov, 1937)

“Oh my! Your tube is so big!”

Giant Radio Tube Produced
CLAIMED to be the largest ever made, a new water-cooled radio tube demonstrated in Chicago stands about eight feet high. The tube takes 18,000 volts in operation. Rated at 250,000 watts each, five of the new tubes will be required to operate a transmitting station now being assembled.

Same wires – many more voices (Oct, 1952)

Same wires – many more voices
Connecting new multi-voice system to open-wire lines, near Albany, Georgia. With new system, 150,000 miles of short open-wire telephone lines can be made to carry up to 16 simultaneous messages economically.

Much of your Long Distance telephone system works through cable but open-wire lines are still the most economical in many places. Thousands of these circuits are so short that little would be saved by using elaborate carrier telephone systems which are better suited for long-haul routes. But a new carrier system . . . the Type O designed especially for short hauls … is changing the picture. It is economical on lines as short as 15 miles. With Type O thousands of lines will carry as many as 16 conversations apiece.

Type O is a happy combination of many elements, some new, some used in new ways. As a result, terminal equipment takes up one-eighth as much space as before. Little service work is required on location; entire apparatus units can be removed and replaced as easily as vacuum tubes.

Moreover, the new carrier system saves copper by multiplying the usefulness of existing lines. For telephone users it means more service . . . while the cost stays low.

IF THE TELEPHONE WERE NOT THERE! (Feb, 1935)

IF THE TELEPHONE WERE NOT THERE!
Many times each day you reach for the telephone on your desk at the office or in its familiar spot at home. It is an old and trusted friend. You scarcely give a thought to what it means to a busy day. Yet suppose the telephone were not there! Suppose—for a week—or a month —you could not call anybody by telephone and nobody could call you! The whole machinery of business and the home would be thrown out of gear.

Orders would be lost—efficiency and profits reduced. You would be out of touch with the world about you.

America needs quick, reliable, efficient telephone service to get things done in the brisk, up-to-the-minute American manner. And it enjoys the best service in the world.

Greater progress has been made in this country because of the Bell System’s one policy, one system and universal service.

America leads in telephone service. In relation to population, there are six times as many telephones in this country as in Europe and the telephone is used nine times as much.
