Skyful of Moons: To aid navigation by ships and planes, a Chrysler Corporation missile engineer, L. Lawrence Jr., has worked out a plan to launch three satellites – Astro 1, 2, 3 – to circle the earth at 600-mile altitude in 105 minutes, in polar orbits crossing the equator at spaced intervals around the world. The satellites would constantly emit radio signals, enabling a navigator to get his bearings from the nearest one, with the help of an almanac giving each satellite’s position at any time. To power a satellite’s radio, an atomic battery would convert heat from radiactive strontium into electricity, by means of a thermopile.
This is a hardware packet switched network, kinda like IP circa 1951.
Dial Switches Message Tubes
By Dialing a number, workers in a Connecticut factory can send written messages and even metal samples to various parts of the plant in about a minute’s time. They are using the familiar old pneumatic tube, the hissing clanging gadget used to make change in many department stores.
This pneumatic tube is different. Wehere older systems required separate tubes to each station, this one has an automatic dial exchange, just like a modern telephone central office, making a few tubes do the work of many. Each carrier has numbers that can be set to guide it automatically to any one of the nine stations that make up the first American installation at the Housatonic plant of the Bridgeport Brass Co. Eventually there will be 20 stations.
Self-navigating robot gets its own charge
A machine that recharges its batteries by finding and plugging into the nearest wall outlet is under test at Johns Hopkins University Applied Physics Laboratory.
Like a hatbox full of bees, it buzzes up and down a hall, probing ahead to avoid open doors, stairs, and other obstacles.
Equipped with sonar, the robot may find use in moon or undersea explorations.
Basically they are saying: “Choose the Army before the Army chooses you.”
This reminds me of mafia thugs demanding protection money and saying: “We can do this the easy way, or we can do this the hard way.”
He just lost his chance to make a choice.
His induction notice caught him with his decisions down. He waited too long to choose Army.
If he had acted sooner, he would have had his pick of more than 300 jobs. And his choice would have been guaranteed in writing before he joined up.
So don’t wait. Choose your specialty and get the best training in the world. In an outfit you can be proud of. There’s no better way to become highly skilled. No better way to fulfill your military obligation.
Your future, your decision … choose ARMY.

Endless Chain Conveyor Moves Cars Thu Auto Laundry
Borrowing an idea from the assembly lines of large automobiele factories, an inventive garage man has devised an endless chain conveyor system which moves cars through his auto laundry to permit a complete cleaning and polishing job in nine minutes.
The patron merely drives his car onto a guide track and steps out. A coupling chain is then attached to the front bumper and the main chain running alond the floor. A button is pressed and the car begins to move. As it passes each section of the track streams of water play on whells and body. A revoloving brush drops from a hinged support in the ceiling and cleans the top of the car as jets of water pour from the brush.
Powerful blowers then dry the car and a giant vacuum system removes the grit and dirt from both the inside and outside of the car.

This is pretty amazing. It’s a Scientific American Article from 1939 describing the splitting of the atom. It was written just after Einstien had written his famous letter to F.D.R and before the initiation of the Manhattan Project, yet it is obvious that scientists were well aware of the potential uses of atomic fission:
It may or may not be significant that, since early spring, no accounts of research on nuclear fission have been heard from Germany — not even from discoverer Hahn. It is not unlikely that the German government, spotting a potentially powerful weapon of war, has imposed military secrecy on all recent German investigations. A large concentration of isotope 235, subjected to neutron bombardment, might conceivably blow up all London or Paris.
Two Elements For One
The Most Important Scientific Discovery of the Present Year is also the Biggest Explosion in Atomic History … Splitting the Uranium Atom
THE Fifth Washington Conference on Theoretical Physics was sitting in solemn conclave when the news broke. Professor Nils Bohr of Princeton and Professor Enrico Fermi of Columbia rose to open the meeting with an account of some research going on in a Berlin laboratory.
Professors Bohr and Fermi are Nobel Prize winners both, and their names are as well known to scientists as Toscaninni’s is to music lovers. The Conference therefore expected something extra special. They weren’t disappointed.
It was January 26, 1939. A few wees before, at the Kaiser Wilhelm Institute in Berlin, Dr. Otto Hahn, a distinguished German physicist, had obtained an utterly unexpected result from some more or less routine experiments. Following the original example of Professor Fermi, Dr. Hahn and his co-worker, F. Strassmann, had for many months been bombarding uranium with neutrons and studying the debris left by this atomic warfare.
It would not have surprised them at all to find radium as one of the products. In fact, they had done so before, or thought they had. Radium and uranium are near neighbors in the table of elements, and it is nothing new for scientists to transform one element into another close to it in weight and electric charge.
But it was news, and big news, to discover barium among the debris — barium, which is only a little more than half as heavy as uranium. It meant that the neutron bullets had succeeded not merely in knocking a few chips off the old block, but in blowing the whole atom asunder with a terrific explosion.
Electricity Records Fencing Hits
Even the ancient sport of fencing has been “wired for sound!’ Contestants in a recent match in England were equipped with trailing wires connected to an electrical apparatus that rang a bell and flashed lights when one fencer’s foil made contact with a vulnerable spot on his opponent. The idea was first tried out at the match between Oxford and Cambridge Universities and made a great hit with fencers and spectators alike.
Devise Gas Mask for Baby
Designed for children under two years of age, the gas mask shown at right was developed by the British Government as part of its precautions against air raids. The helmet is slipped over the infant’s head and shoulders and strapped firmly around its chest so that the headpiece is sealed from the air. A small bellows, operated by the mothers hand as shown, supplies air to the helmet. The air is chemically purified of all poisonous gases before reaching the child.
