...industry could save 50 millions per annum in refining costs if motor designers could safeguard motors against fuels containing a higher percentage of sulphur than is now left in good grade gasoline. Motor designers aim to protect motors from sulphuric acid corrosion by eliminating condensation of the water vapor from burning fuel...
Whiskey Test. To the University of Cincinnati came 300 volunteers who drank good whiskey and then let their alcoholized breaths pass through a solution of 50% sulphuric acid containing a trace (1/3%) of potassium dichromate. This solution is ordinarily reddish yellow; alcohol vapor makes it change to a bluish green. The more whiskey the Cincinnati bibbers swallowed and the more drunk they became, the more bluish green became the solution. There is so definite a relation between degree of intoxication and the sulphuric acid-potassium dichromate tint, that Cincinnati judges have used its evidence in arrests for driving motor cars...
...Eastman Kodak Co. for new "K-panchromatic" plates by which flying observers can photograph the earth through smoke screens and light fog. The plates are treated with a secret cyanide, "krypto-cyanide," sensitive to infra-red rays which, though invisible to the eye, penetrate smoke and water vapor to record an image in the camera. The significance: protection for wartime mapmakers...
...also several from the Great War. Professor McAdie was Senior Aerographic Officer, U. S. N. R. F., of the Nary during the War, and trained a considerable number of officers at Blue Hill for aerographic work overseas. "Weather in Peace," "The Structure of the Atmosphere," "Clouds, Fogs and Water Vapor," "Lightning," and "Droughts, Floods and Forecasts," are the subjects of the other five essays. There is thus a considerable variety of subjects, and each chapter contains many items of popular interest. For example, we learn something about "frost fighting" in California; the value of expert testimony on the part...
...principle of heat-induced ice is simple. Apply a vacuum pump to water, draw off the vapor, the result is ice. Silica gel grains act as a pump. In the pores of the silica gel, the vapor liquefies, giving it enormous power to absorb vapor. With a small flame under the gel the condensed vapor is driven off, so that its absorbent qualities are unimpaired until the remaining water is frozen...
