Takes the Drudgery Out of Mopping

MADE of cellulose sponge, the “business end” of this new floor mop absorbs twenty times its own weight in water yet remains soft and workable. A rectangular metal part with handle provides a squeezing device that wrings out the soiled water, which need not touch the operator’s hands. Only a slight pressure is necessary to squeeze out the water. There are no gadgets nor parts to get out of order. The mop can be used easily and quickly for cleaning walls as well as floors, and rugs also. The mop head can be detached for use in window and auto washing.

This is one of those articles where they happen to get it exactly right. How many people alive today have ever even seen a mechanical television? The CRT is probably one of the more important inventions of the last century. It made TV and computer displays practical and economical. It was even used for data storage.

Kids growing up today will never learn the joy and muscular-skeletal pain one received simply by attempting to lift a 30″ TV on to a table.

Fastest Television Scanner – The Cathode-Ray Tube

Television receivers of tomorrow will employ this newest scanning device, which “paints” the image on a fluorescent screen with a beam of electrons moving at incredible speed.

THE Cathode-Ray Tube gives every promise of becoming the real panacea for all of television’s problems. There are strong rumors that one of the largest television and radio interests will, probably, place on the market this season a television receiver for home entertainment, in which a specially designed cathode-ray tube will do the scanning, and take the place of the now familiar revolving scanning disc and motor. The cathode-ray tube has several notable advantages over the mechanical scanners; one of which is that it eliminates all rotating or other moving mechanical parts. Read the rest of this entry »

Transistor – mighty mite of electronics

Increasingly you hear of a new electronic device — the transistor. Because of growing interest, RCA—a pioneer in transistor development for practical use in electronics—answers some basic questions:

Q: What is a transistor?

PRE-TESTING MOVIES

ARI tells producers in advance whether you will like a new picture
By HAROLD WOLFF

Is there a scientific method of forecasting audience reaction to a motion picture before release? “Yes,” says Dr. Frank Gallup, father of the election polls—and cites an impressive record of success for his Audience Research Inc. Certain victims of adverse conclusions say, “No. Gallup polls don’t mean a thing. They lift a manhole cover and ask a question, and right away anybody inside the manhole becomes a critic.” Read the rest of this entry »

If you’d like an idea of why you don’t see a lot of ads using handwriting style fonts, check out this screen shot of my OCR app. (“7hen science discovered twat”)

Capitalization in this particular ad is also really hard to determine. With text that is in ALL CAPS, letters that are supposed to be capitalized are generally in a larger font size. But look at that first paragraph; the only text in lower case is “once planted” which is just weird.

Anything with actual handwritten text I have to almost always transcribe by hand.

Also, on the content of the ad, what isn’t made from soy today?

Unlocking Secrets of the Soy Bean

The soy bean, once planted only as a rotation crop, was plowed under to increase the fertility of the soil.

Then science discovered that soy bean flour is wholesome… the oil makes good paints and salad dressing…the meal is good cattle feed… the fibre makes plastics… but first extraction methods didn’t get all the oil… only partially separated the other ingredients. Read the rest of this entry »

Seedless Tomato Grown in Texas

AFTER long experiment, a seedless tomato lias been developed by an Amarillo, Texas, llorist. The flavor of the tomato is improved with the disappearance of the seeds, it is said.

The seedless tomato was developed after years of taking cuttings from plants producing tomatoes with the fewest seeds. New plants were grown from the cuttings and the florist now has a complete group of plants showing the stages of seed elimination.

Muting the TV used to be a bit trickier.

Errorless Typewriternot only saves time, materials and the secretary’s nerves but makes neat-as-a-pin copy with even right-hand (as well as left-hand) margins. The electrically driven machine does not print directly onto the paper but sets up a visible line which can be corrected and adjusted for spacing before it registers.

ROCKETING to the Moon

by Prof. R. H. GODDARD, B.Sc., A.M., Ph.D.
as told to William Robertson

FOR YEARS scientists have been forced to study the moon through its reflection in the observatory mirror. Since the moon refused to come closer to the earth than 220,000 miles, however, man may find it possible to exercise the alternative of Mahomet and go to the moon, in the opinion of a distinguished man of science.

For comparison, when the modern descendant of these atom smashers, the Large Hadron Collider, comes fully online it will accelerate protons to 7 trillion electron volts. They will be travelling at 99.9999991% the speed of light and have an effective mass 7460.52 times what they have at rest. This is so fast that even though they will be making 11,000 orbits around the 27km ring per second, from the proton’s perspective time dilation will make each orbit seem to last about 2 minutes.

WATCH THESE ATOM-BUSTERS

The new synchrotrons open up prospects packed with thrills.

Anything that you see around you is made of matter. All matter is simply concentrated energy; when it is exploded, as in the blast of an atomic bomb, part of it becomes released energy. That was reasoned out by Einstein years ago; and the venerable scientist’s reasoning certainly has been borne out by the achievements of the nuclear physicists who produced the atomic bomb.

Poor Kids More Immune to Germs

SURPRISING facts about the numbers of Canadian school children who get germ diseases such as measles and scarlet fever were reported to the Canadian Public Health Associations. Contrary to what might have been expected, children from the better districts of the city, a survey disclosed, were found to have had more cases of the germ diseases classed as communicable than children from poorer neighborhoods
