Camera Gives Print in a Minute

NOW you can snap a picture and see it only a minute later. The camera that does this is an entirely new type. It’s the first production model of the Polaroid Land Camera (PS, May, ’47, p. 150). It costs less than $100.
The camera uses a special film that gives you eight pictures. Each one costs just a little more than you’d pay for drug-store processing of ordinary prints of this size.
Contained in the roll of positive paper are eight tiny capsules of jellied reagent. When you advance the film after snapping a picture, a capsule is opened as it passes between two rollers. The jelly simultaneously develops the negative and forms a print. You pull out the print after a 60-second wait. For extra prints, you make another exposure or copy the original.
One control sets both shutter speed and lens opening. Numbers from 1 to 8 in an opening above the lens show whether the camera’s set for bright sun or poor light conditions. The camera has flash contacts.

Camera Records “Eye Interest” of Reader for Items on Page

Researchers using an improved tool virtually look through the eyes of a reader to determine what interests him in advertising, art and reading material. Blinders or glasses cause him to move his head as he glances at different sections of a page. A small spotlight affixed to his head focuses a beam of light on a reproduction of the page just above the reading rack, in the identical area observed by the subject. A camera behind the subject, snapping at a constant speed of two frames per second, records the exact location, duration and sequence of every glance. The film is then read and analyzed. It shows time for each pause.

This show looks like it was really cool. It’s basically American Inventor without the overt competition.

BBC Puts Inventors On TV
INVENTIONS ARE the stars of one of the most popular television shows in Britain.

The Television Inventors’ Club of the British Broadcasting Corporation has been on the air for seven years. During this time more than 7000 inventions have been submitted to the club, of which 580 have been shown on the air. A quarter of these have caught the eyes of manufacturers and many are already in production.

The inventions range from a simple shirt stud which allows for the shrinkage of the collar, to a compressible ship’s fender which eases a 24,000-ton vessel against a dock.

A number of British inventors have hit the jackpot through the program. One of them actually did it with a better mousetrap, and the world has already beaten a path to his door to the tune of over a million sales. Years of patient observation taught the inventor that a mouse twists its head when approaching the bait and nibbles from below. His trap therefore springs when the bait is lifted—not pushed down. A tidy profit was also made by the inventor of a stair elevator for invalids. A moving step, carried on rails, is drawn up the staircase by a cable and winch. More than 500 inquiries poured into the BBC when this device was shown on TV.

A Cure For Crime in the Parks

Here is a modern solution to the problem that is plaguing every large city in America today!

By Robert Hertzberg

A COLLEGE professor walking his dog is knifed to death. The small daughter of a foreign diplomat is robbed of her bicycle. A woman pushing her baby in a carriage has her purse snatched.

Where do these crimes take place—in a lawless Suez port town, or in the very heart of America’s richest city? You only have to read the newspapers to know that murder and mugging are frequent occurrences in New York’s famed Central Park, an otherwise beautiful oasis of lakes, playgrounds and trees bounded on three sides by the world’s plushest apartment houses and on the other side by an incredibly overcrowded and festered slum.

Am I the only one who thinks this looks a bit like the Oscar Meyer Weinermobile?

SWEDISH DREAM CAR

SWEDISH carrot juice maker Sig-vard Berggren built his own Future. That’s the name of his dream car which looks like a wingless plane. He installed a Ford V8 engine in a ’38 Dodge chassis and plans to add a 200-hp mill in the rear, to give the Future a 140-mph-plus speed. That’s a real fast-flying Swede.

FUTURE was built in spare time, looks strikingly like a plane.
FISH EYES are headlights and the huge gills are the air inlets.

CABIN behind driver’s seat has ample room for table, chairs.

Wow, that guy looks scarily entertained by his movie. Think of it as the Video Ipod of 1952.

Obsolete Autos Utilized To Teach Safe Driving
A NOVEL and practical way of training high school students to be safe drivers has been developed at the Lane Technical School in Chicago, Ill. Obsolete autos are cut down until only the driver’s seat, brake, clutch and shifting lever controls remain. These are used as desks by the students.
The controls are wired to lamps mounted on a panel in the classroom which enables the instructor, William A. Sears, to check each student’s reaction to traffic situations flashed onto a motion picture screen. After this primary instruction, the students drive real cars over a $35,000 practice course featuring every type of lane, curve, grade, etc.

Machine Builds Muscles

THE young lady below is getting all the beneficial effects of rowing and riding from the machine on which she is exercising. It strengthens and stimulates muscles and internal organs.

The guy in this article absolutely fits my definition of a hacker. There was a problem where two radio stations were broadcasting the same syndicated content on the same frequency. Listeners near either station had no problem. However there were locations where both signals could be recieved. This would be fine, except for the fact that the cable running to one of the stations was longer than the other, so the signal was delayed by 1/23000 of a second. Enough to cause destructive interference. So the engineers solution was to create an acoustic delay line out of 23 feet of lead pipe stuffed with cloth and gauze with a speaker on one side and a microphone on the other. The slower speed of sound delayed the signal long enough for the two stations to be in sync.

DELAYING THE BROADCAST

A FEW weeks ago the popular radio show, Information Please, used the following catch question:

“Who hears the speaker first, the people at the back of the auditorium, or the people 3,000 miles across the country who are listening to the broadcast of the speech?”

The catch was that radio waves travel with the speed of light, 186,000 miles per second, and sound waves only 1,080 feet per second. Therefore, the answer went, the listeners three thousand miles away would hear it first.
