I’m not really sure what they’re trying to say in this ad… I think it’s either: “Marvel Oil will blow up your car”, or “Marvel oil is made of atomic bombs”.

I love the name “Devil Junk” that he gave his jeep, though it does make it sound like the kid might have a heroin problem.

The midget jeep at the left was built by Valentin Labata. of Leyte. Philippine Islands. He starts his letter by asking, “I wonder if Filipinos are qualified to enter your Workbench Award contest?” They sure are, Val. We base our awards on ability, not nationality. He goes on to say. “A 3-hp. Wisconsin engine drives one rear wheel through a belt, giving 25 m.p.h, top speed and 75 to 80 miles per gallon. The brake works through the other rear wheel. I received help from my father, who donated the engine and the wheels, and two relatives. That’s me in the middle. The other two boys are the helpful relatives.”

Of course the picture implies that someone is aiming at your head. And expecting a bullet proof vest to protect you from a headshot is a little like thinking that wearing a condom will protect you from a dirty needle.

THE ROLE OF THE COMPUTER (Sep, 1952)

This is the third in a series of 5 articles I’ve scanned from an amazing 1952 issue of Scientific American about Automatic Control. Discussing automatic machine tools, feedback loops, and the role of computers in manufacturing and information theory, these are really astounding articles considering the time in which they were written.


THE ROLE OF THE COMPUTER

The multifarious control loops of a fully automatic factory must be gathered into one big loop. This can best be done by means of a digital computing machine

by Louis N. Ridenour

IF THE thermostat is a prime elementary example of the principle of automatic control, the computer is its most sophisticated expression. The thermostat and other simple control mechanisms, such as the automatic pilot and engine-governor, are specialized devices limited to a single function. An automatic pilot can control an airplane but would be helpless if faced with the problem of driving a car. Obviously for fully automatic control we must have mechanisms that simulate the generalized abilities of a human being, who can operate the damper on a furnace, drive a car or fly a plane, set a rheostat to control a voltage, work the throttle of an engine, and do many other things besides. The modern computer is the first machine to approach such general abilities.

Computer is really an inadequate name for these machines. They are called computers simply because computation is the only significant job that has so far been given to them. The name has somewhat obscured the fact that they are capable of much greater generality. When these machines are applied to automatic control, they will permit a vast extension of the control art— an extension from the use of rather simple specialized control mechanisms, which merely assist a human operator in doing a complicated task, to over-all controllers which will supervise a whole job. They will be able to do so more rapidly, more reliably, more cheaply and with just as much ingenuity as a human operator.

MI’s HIGHWAY KART

You don’t need a trailer or a station wagon to haul this kart to a track you can drive it there on public roads!

By R. J. Capotosto

DRIVING a kart is a real thrill. Seated on a low-slung frame only inches from the ground, you feel as if you’re doing 80 mph when you’re doing 20. Yet it’s surprisingly safe. The low center of gravity and a width two-thirds the length make it almost impossible to flip a kart in a tight turn. Just about everyone who tries a kart gets the urge to own one—and if you’ve got that urge, you get a bonus in building the MI Highway Kart.

Since karts are generally driven on special tracks, it is not necessary to register them. However, transporting a kart is often a problem. It can be hauled in a station wagon—if you own a wagon—or it can be towed on a trailer. Either way, the lugging can be quite a nuisance. With this in mind, our model was designed so that registration could be obtained, making it possible to drive the kart to its destination on public roads.

“REPORT FROM ROTTERDAM”

Secret underground broadcasters still send out news of what the brave Dutch are doing to upset the Nazi “new Disorder”. Radio furnishes the ONE link between conquered countries and the outside world. In war, as in peace, The Radio Shack continues to play its part in the field of communications . . . now supplying vital equipment to help hasten the day of victory, and revenge for the rape of Rotterdam.

This is the second in a series of 5 articles I’ve scanned from an amazing 1952 issue of Scientific American about Automatic Control.

FEEDBACK

It is the fundamental principle that underlies all self-regulating systems, not only machines but also the processes of life and the tides of human affairs

by Arnold Tustin

FOR hundreds of years a few examples of true automatic control systems have been known. A very early one was the arrangement on windmills of a device to keep their sails always facing into the wind. It consisted simply of a miniature windmill which could rotate the whole mill to face in any direction. The small mill’s sails were at right angles to the main ones, and whenever the latter faced in the wrong direction, the wind caught the small sails and rotated the mill to the correct position. With steam power came other automatic mechanisms: the engine-governor, and then the steering servo-engine on ships, which operated the rudder in correspondence with movements of the helm. These devices, and a few others such as simple voltage regulators, constituted man’s achievement in automatic control up to about 20 years ago.

Hearing Aid for Cat
“Unfortunate” heard for the first time recently when the cat’s owner, Mrs. A. H. Cooper of Fort Worth, Tex., had a hearing aid fitted to the feline. The hearing aid is the latest of a series of steps by Mrs. Cooper to improve the life of the unfortunate cat, which was born deaf, crippled in the hind legs and had no teeth until the age of two. The owner massaged the cat’s gums until the teeth finally came through and had a wheeled support built which enables the cat to scoot around the house.
