Plastic Shell Equips Phone For Two-Way Listening
Two persons can share the same telephone with a device patented by Roger Heap of Lyme, Conn. Simple in design, it consists of a T-shape plastic shell which cups over the receiving end of the phone. The hollow arms transmit the message to listeners at both sides. Heap fashioned the device so that he and Mrs. Heap could join in three-way conversations with their son in Detroit.
Pipe Is Effective Tear Gas Gun
TEAR gas guns have taken many forms in the past and now the weapon comes out in the form of an innocent looking pipe, which no one could possibly suspect of evil purposes. Fortunately its shape permits it to be held like a pistol. The stem does duty as a barrel to spray the smoke in the culprit’s face, while a small knob on the underside works as the trigger. The pipe may be carried in the same manner as its inoffensive brother. How it is held may be seen from the photo above.
Surgical Mask Made From Transparent Material
INVENTED by a well known doctor, a new type of surgical mask is constructed from transparent material and, due to its flexible metal frame, can be instantly adjusted to fit the contour of the face. By permitting lip reading, the transparent mask enables doctors and nurses to converse more conveniently during an operation. An opening in the bottom of the mask permits air to circulate.
Heh, could you imagine this club now? The liability for the city would be insane if someone ever got hurt.
“So, let me get this straight…. you had the children build their own diving suits made out of water heaters and garden hoses, then sent them down into dangerous wrecks. Didn’t you think it might be a bit dangerous?”
“No? Um…. what as the name of that club again?”
“Suicide Club” Makes Own Diving Suits
THE “Suicide Club” is an apt title for a group of eight Cali-fornian youths who, assisted by friends at the air pumps, indulge in small scale deep sea diving.
Under the direction of Jack Cheaney of the Los Angeles playground department, the amateur divers have equipped themselves with complete homemade outfits constructed from odds and ends. Sections of water heating tanks, fitted with windows, provide suitable helmets for the sub-surface workers. Ordinary garden hose is attached to bicycle pumps which furnish up to 20 pounds of air pressure.
Salvaging sunken craft, retrieving lost anchors and freeing fouled lines are the everyday jobs of this venturesome group.
Very cool article from 1939 about the first programmable electronic sign in Times Square (think the grandfather of the Jumbotron). Every single change of a light, and there are 27,000 of them, is punched as a row on a 160 column roll of paper that gets fed through the vast machine.
Oh, and in response to the question posed here:
“The paper is wide enough for 160 perforated holes across. One hundred holes to represent all the lights in each zone. Thirty to represent the zones in all the sectors. And nine to represent the sectors.”
“But that’s only 139 holes’” we remark brightly.
“Well, there are nine holes to erase the sectors.”
“And nine for flashing the sectors on and off.”
“Andâ€”” Mr. Latz scratched his head. “There’s three more for something else, but darned if I know what they are!”
Big City Sign
“How does it work?” is the question most frequently heard, as New Yorkers and visitors gaze at the sign whose color and action make it one of Broadway’s most startling attractions.
27,000 light bulbs! 40 miles of wiring! 500,000 connections!
THESE figures are impressive, but an electric “spectacular” must depend on more than sheer size to attract attention in New York City’s Times Square, which has the most imposing collection of electric signs in the world. It must have action, color, and originalityâ€”and that’s just what the Wonder-sign, newest and brightest addition to the Great White Way’s signs, has.
Did you think that the baby monitor was a recent invention?
“Radio Nurse” Watches Child
A “RADIO NURSE” now brings the nursery into the living room, kitchen, or any other room desired. When a child is sleeping or playing in a room when no older persons are present, every sound within that room can be transmitted to any spot in the house. The outfit consists of a pickup unit, placed near the child to be “watched,” and a loudspeaker, which can be placed in any convenient location.
Boy, with a snazzy name like Carfeteria I can’t understand why these never took off.
“Carfeteria” Serves Motorists at Wheel
Eating is made easv for motorists who patronize the wheellike Los Angeles Motor-mat shown above. Spokes of the wheel are tracks along which run small carriages. You drive into one of the 20 stalls, where a carriage and menu are waiting, make your selection, write the order, and press a button. Presto! the carriage whizzes into the kitchen, stopping along the way only long enough for an attendant to figure the cost. In a few minutes the meal is shot back to your car. When you have finished eating from a lap tray, you put the empty dishes back in the carriage-plus the price of the meal.

Robot Song Master Stimulates Sunday-School Singing
Youngsters sing their lungs out to please a robot who draws big crowds to a Seattle Sunday-school class. “Sam” has eyes of radio tubes and light-bulb ears, a big square face and a grinning mouth. As the volume of singing increases, bulbs light up and Sam’s long red tongue wags back and forth. Besides functioning like an applause meter, Sam tells short Bible stories by means of a hidden tape recorder.
Very interesting (and long) article from the dawn of the TV era (1939) explaining all of the hurdles; technological, economical, political, etc that will have to be jumped before TV is widely available. A lot of it sounds similar to the current emergence of internet based video distribution. Just as they are today, the major movie studios and radio networks were unsure of how to handle this new beast. They feared it would replace them, so the bought in, then gave up, then bought in again, a lot like what we’re seeing with TV networks allowing their content to be distributed online.
According to the printed stories, Paramount will soon be set for big-scale television on a national basis, with transmitting stations on both coasts planned to give the public “this new type of entertainment”. When sound broadcasting began to loom as the movies’ first really serious competitor, Paramount bought an interest in the Columbia Broadcasting System, and then dropped it when they learned that there was nothing wrong with the movies that good pictures couldn’t cure. Now, apparently, Paramount is making another attempt to cover itself, and protect its stockholders by entering television in case it does materialize into something more than hot air.
There are also some interesting parallels to the DRM questions flying about today:
He will also make receiversâ€”in fact, he’s making one right now for the Empire State signalsâ€”but under the Paramount set-up the new receivers will reproduce only his broadcasts, not the NBC or CBS ones!
And some funny assumptions about radio’s future:
No grade “A” broadcast station uses phonograph records; will they step down a notch and use “image records?”
The answer I guess was, yes. Though sattellite and streaming media are chaning this, for the last 50 years, TV and Radio content (with the exception of sports, news and talk radio) have been ruled by recorded programming..
