Distant places, noted stars of the stage, industry at work, drama, thrills, all living on a screen in your radio set!
No dream thisâ€”for television is now perfected and ready for a hungry market, ready for your home! And before many months pass its wonders will be commonplace, its intricacies clear to every radio set owner.
Aerocoupe Speeds 75 M.P.H.
HIGHLY streamlined and following accepted aeronautical design in construction, a novel aerocoupe developed by Richard Crossley, of East Haven, Conn., has a top speed of 75 m.p.h. The cabin resembles an airplane fuselage, featuring longerons, braces, etc. For traction, the vehicle is equipped with three airplane-type wheels.
Ahh, the birth of the hanging chad.
Electricity Grades Student Papers
IMPERSONAL electricity, which never grows tired or irritated by wrong answers, will be used in several schools this winter to correct examination papers. By means of a small device invented by Joseph Sveda and Herbert Lehmann, two New Jersey high school teachers, the papers will be electrically corrected at the rate of 25 a minute.
On the examination paper, the student punches out disks corresponding to “yes” or “no,” and “true” or “false” in answer to the questions. The correct perforations set up an electrical contact when passing through the machine, and the number of contacts represents the student’s grade.
Builds Automatic Lard Ladling Device
A DISPENSING device that enables him to measure out any amount of lard in about one-fifth of the time required by the usual hand-dip method has been developed by Martin L. Jackson, a store operator in Winston-Salem, N. C. The home-built dispenser features a small handle which, when turned, ejects the lard from a special spout in the form of a thick ribbon, as shown in the photo. The “secret” of the automatic ladling unit is a rubber diaphragm and a small jack which apply a constant pressure against the supply of lard, forcing it out of the spout when the handle is slowly turned.
Our Air Force – A Farce!
“We are five years behind England and Germany in planes, engines and equipment and a full 10 years behind in the development of our air force as a third arm of defense”
by Major Al Williams
AMERICA is not an airpower! We have, instead, two flying servicesâ€” one with the Army and the other with the Navyâ€”and they are not adequate for the defense of the nation.
As airpower goes, I estimate that we’re about five years behind Europe’s leaders in planes, engines, and equipment, and a full 10 years would be needed for the maturity of a brand new service. This goes in spite of a European demand for American fighting ships, in spite of “downhill” speeds of from 575 to 700 m.p.h. claimed for blunt-nosed radial engined planes, and in spite of a college-student civilian training program which portends to be a solution to the pilot problem.
Our air-cooled engines are good, and hold their own with foreign radials. Our ships came in handy in the scramble for planes after the Munich incident; they are fill-ins for building programs that weren’t geared to air war. But they are powered by engines which can’t approach the English Rolls-Royce streamlined power plants, for instance, and none of the planes is in the same speed bracket with standard fighting ships of the airpower nations.
Just the other day as a plumber was cleaning all of the delightful muck out of my clogged sewage line, I thought “Gee, I envy that guy!”

Make the POP’tronics Secretary
Tell your friends that their telephone messages to you will he recorded by electronics
By TRACY DIERS
HOW WOULD YOU LIKE to have a secretary who will answer your phone and take messages at any hour of the day or night but who will demand no pay and no coffee breaks? Impossible, you say? The miracle of electronics has all but removed the word “impossible” from the dictionary.
There are two types of systems you can build which will do this job for you. The deluxe system requires two tape machines or one tape machine and one disc machineâ€” when a call comes in, it plays a recording of instructions and then switches over to record the message. The simpler type, to be described here, requires only one recorder and anyone who can put together a small amplifier can build it.
What, no lawn darts?
THIS half-bow device is something different in the line of archery equipment. Its name is derived from the fact that its arrow is propelled by a whipping motion of the arm and bow. Arrows are made from dowels and may vary in length from 12″ to 18″. Bow string is twisted and waxed shoemaker’s thread or strong twine. Wrap cord on handle.
HERE is a play version of the weapon used by the South American Gauchos. Two types of targets may be used for this rubber-ball Bolas; either bowling pins or six small, colored sticks placed in the ground 3″ apart. The object of the game is to see how many pins or sticks can be knocked down. To throw the Bolas, grasp it by the knot and whirl it rapidly over your head, releasing it toward the target. Your first throws may be wild but practice will make perfect.
Two-Wheel Skates Cut Noise
Centered wheels give these new roller skates the feel and maneuverability of ice skates. The artificial-rubber wheels, rounded instead of flat, are said to be less noisy, speedier, better for pivots and sudden stops. The two-wheelers are made by the Rocket Skate Co., Burbank, Calif.
Now ad men have a new way to persuade you. They can pop a suggestion into your mind, using TV or movies, without your knowing it
TV’s New Trick: Hidden Commercials
By Wesley S. Griswold
PROBABLY you’ve heard aboutâ€”perhaps even worried aboutâ€”a revolutionary new way to beam messages into the human mind. Especially suited to TV and movies, the new idea-injecting technique is said to work while you, all unawares, are innocently enjoying the program. The idea-words appear superimposed on the picture images too fast and too dimly to be seen in the normal way. Yet they register on your mind.
Despite rejection by the national networks, uneasy skepticism by the F.C.C. and alarm from people who fear that this strange development may bring wholesale invasion of privacy and risk of political tyranny, two means of reaching people’s subconscious minds by television are currently being tested.
