Reception On Moving Train
IN A recent experiment carried out, in England, by the Baird Co., television images were successfully picked up on the portable receiver and scanner shown at the upper right. The image was observed in the window at the right of the scanner, appearing on the side of the disc. A suitable aerial was supported on the roof of the car and the ground connection was made through its axles and wheels.
Operating a TV station using electro-mechanical equipment looks really hard. That camera looking thingy at the bottom of the page is not in fact a camera, but an arc lamp. In front of the lamp is a spinning disc with holes punched in it which scans the light across the subject. The “camera” is actually composed of those six light-bulb looking things in front of the subject. They are just ordinary photo-electric cells.
And to view it at home? Here’s what you need:
“you will require a 60-hole scanning disc, revolving at 1200 revolutions a minute, giving 20 frames a second. Further, you will need two short-wave receivers, if you desire to pick up both image and voice frequencies. The images are transmitted on 107 meters, and the sound is sent out from W2XE’s shortwave transmitter on 49 meters.”
Latest Television Broadcast Station
CHICAGO, Toronto, Boston and Washington have recently reported the regular reception of both “sight” and “sound” signals from the new Columbia television station W2XAB, and its accompanying sound transmitter W2XE. The Columbia “telecasting” station was opened on July 21 last, when the Hon. James J. Walker, mayor of New York City, lifted the curtain from the photo-electric cells; which formally marked the opening of the station. The television transmitting apparatus and antenna systems are adjacent to the studio, which is located on the 23rd floor of the Columbia Building at 485 Madison

THE TRUTH ABOUT TELEVISION
Veil of secrecy keeps television from American homes while nearly 5,000 sets are in operation throughout Great Britain.
AMERICANS have always taken pride in their technical superiority. Our proven ability to excel other nations in the rapid development of new industries through the application of machines and scientific improvements has been recognized far and wide. And yet, in the very attractive field of television we are laggards. It is a strange situation and one that has been responsible for much comment by laymen and the press.

Television Will Carry the Mails

A twinkling beam of light records a picture thousands of miles away. It is facsimile transmission- an interesting feature of this authoritative article on the future developments of radio and television.
IN HIS struggle for new information, man has been reaching farther and farther into mysteries beyond his accustomed sphere; farther with the runner through the forest . . . farther with camel caravans across trackless plains . . . farther with ships into uncharted oceans . . . seeking speed, and relishing the advantages of new contacts. From the start, mankind has struggled for better communication.
Juke Box Gets New Look
A nickel in the slot will buy you one televised prize-fight round if the neighborhood tavern is hep to the latest thing in juke boxes. This is a chrome-and-mirror-bedecked coin phonograph, made by the Videograph Corp., of New York, with a 12-inch television screen added. You can choose your own records in the usual way, but the manager decides whether your five cents will buy a three-minute glimpse of television. And since he operates the controls, he also picks the program. If jive, wrestling, and boxing fans are gathered in one place, he’d better be a Solomon.
When a man-size spider walks a giant web, when scissors draw the villain’s blood or a lobster spits in the waiter’s eye, put it down to
SEATED AT A SIDEWALK TABLE in a Paris cafe, a customer watched in fascination a huge, freshly cooked lobster placed in front of him by the waiter. Each time he reached for the lobster the huge shellfish swiftly moved its large claws protectingly over its head. Reaching for a hammer, the would-be diner attempted to hit the lobster but each time the claws parried the blow. The man finally called the waiter to see what he could do with the reluctant lobster. As the waiter bent over to inspect the lobster and its strange actions more closely a stream of water hit him in the eye.
CREATING A NEW WORLD WITH ELECTRONICS
How far away is the pocket-size TV camera?
Samples were used at the last political conventions.
Production modelsâ€”built around subminiaturized circuits requiring semiconductorsâ€”can be expected any day. The proved reliability of Hughes diodes, even under severe shock or weather conditions, makes these tiny, compact semiconductors a logical choice for such circuits.

Also, I love the fact that they didn’t spring for a color ad.
WHAT TIME IS GREEN?
In color television, the colors on the screen are determined in a special way. A reference signal is sent and then the color signals are matched against it. For example, when the second signal is out of step by 50-billionths of a second, the color is green; 130-billionths means blue.
