ELECTRIC MAP ANSWERS QUESTIONS (Nov, 1936)

ELECTRIC MAP ANSWERS QUESTIONS

AN ELECTRIC map now automatically aids motorists seeking travel information at the headquarters of the Automobile Club of Southern California. At the touch of a button, the mileage to any of 1,000 points within the state flashes from an electrical panel in luminous green figures, while a bright red spot indicates the location of the place upon a map twelve feet high.

Costly Ball to Guide Astronauts (Nov, 1961)

I wonder if this was part of the inspiration for Gravity Probe B, a satellite designed to measure how spacetime is warped by the earth. It had some seriously spherical gyroscopes:

At the time, the gyroscopes were the most nearly spherical objects ever made. Approximately the size of ping pong balls, they are perfectly round to within forty atoms (less than 10 nm). If one of these spheres were scaled to the size of the earth, the tallest mountains and deepest ocean trench would measure only 2.4 m (8 ft) high

Costly Ball to Guide Astronauts

A LITTLE metal ball, worth more than 30 times its weight in gold, is being tediously fashioned into shape as part of a guidance system that may help future astronauts find their way around the universe.

General Electric Co., Schenectady, N. Y., says the sphere of niobium will be a critical part of an inertial guidance system giving pinpoint accuracy to navigation of a jet, ocean liner, space ship, or submarine—largely as a result of suspending it in a vacuum and rotating it as the heart of a super-precise gyroscope.

Foolproof Navigator (Sep, 1947)

Foolproof Navigator

The revolutionary now Decca Navigation System is so simple that the navigators of “blind” ships or planes gel their fix by merely matching two sets of figures.

By Gold V. Sanders

A RADIO navigation device so simple that a novice can navigate a ship or airplane with it has been perfected in England and is now being offered in this country. It is so simple in fact that all one has to know is how to read some simple figures and match them with the same figures on a map in order to get a “fix” on a fog-bound ship, or on a plane flying in darkness or above the clouds.

Highway “Beam” For Motorists (Very Early Proto-G.P.S) (Dec, 1944)

Highway “Beam” For Motorists

War-born device will guide peacetime motorists unerringly to their destinations —or plot their course as they go along.

EARLY one morning last year, just before sunrise, two men in a jeep found themselves lost in Washington. That is a horrible fate which can happen to anyone and often does, but in this case it was serious. In the back seat of the jeep was installed the first model of a secret new device which was being delivered under cover of darkness to the Army Engineer Board at Fort Belvoir, Virginia. It had to be there at 8:00 a. m. to be inspected by a full board of high Army officers. But the two men in the jeep, newcomers to Washington, were stymied.

Compass Mounted on Hat Brim Is Handy Guide for Hiker (Dec, 1936)

Compass Mounted on Hat Brim Is Handy Guide for Hiker
Always there to guide you, yet never in the way, a tiny compass clipped to the hat brim is a useful companion on a tramp through woods or mountains, a hunting trip, or bicycle expedition. It clips on the hat or cap just above the line of vision. A floating disk with the needle attached bears the initials of the four points of the compass, and through a window in the base the di-
