Miscellaneous Cool Stuff (Jul, 1930)

I can’t decide which picture I like better, the two guys fighting with sand blasters or the gas masks.

Miscellaneous Cool Stuff
SHOT FIRED AGAINST STEEL TO CLEAN IT

A scene suggesting a fantastic stage setting is enacted daily in a remote room of the General Electric Company’s plant at Schenectady, N.Y. There, under the glare of powerful lights, gnomelike workmen scour large steel castings to prepare them for a coat of paint. Hoses in their hands discharge a continuous, clattering volley of fine steel shot upon the part being cleaned. In this dusty atmosphere, the men must wear headgear like divers’ helmets, with fresh washed air supplied to them continuously through tubes from outside the room.

High Soarer: the Switchette in the right hand of Mrs. Dolores Mohlmann reached an altitude of 250 miles—higher than any other man-made article. It was attached to a two-stage rocket (model in left hand) and was used to discharge a smaller rocket at an altitude of 20 miles. Portion of tail section with this gadget was found at White Sands.

“Cross-eyed” X-ray Casts 3-dimension Image (Nov, 1932)

“Cross-eyed” X-ray Casts 3-dimension Image

X-RAY shadowgraphs have heretofore displayed only two dimensions, height and width, but with the recent development of the “cross-eyed” X-ray a third dimension, depth, is added, making the image appear like a sculptured skeleton.

The three-dimensional X-ray is the invention of Prof. Jesse W. Du Mond, a Pasadena, California, scientist, who calls his instrument a “Stereofluoroscope.”

The main element of the machine is a pair of X-ray tubes whose beams, directed against the patient as illustrated in the drawing above, intersect in the body, thus casting shadows in two different planes.
