Analytical Methods for Certain Metals Including Cerium, Thorium, Molybdenum, Tungsten, Radium, Uranium, Vanadium, Titanium and Zirconium

Description: From Introduction: "This chapter indicates the methods of determining several of the alloy metals when occurring together in the same sample. Most materials seldom contain more than two or three of these elements, but considerable time may be saved if determinations can be combined. Details of the analyses and separations are not given here, as they have been covered more fully in other chapters. Whenever possible, reference is made to the particular chapter. Only sufficient directions have been given to outline the method of procedure, actual conditions for the separations being presented on other pages."

Investigation of Toxic Gases from Mexican and other High-Sulphur Petroleums and Products: Report by the Bureau of Mines, Department of the Interior, to the American Petroleum Institute

Description: From Scope of the Work and Findings: "The work was divided into two parts, namely, field work and laboratory investigations. The most interesting and important of the laboratory investigations. The most interesting and important of the laboratory findings were: (1) The presence of hydrogen sulphide (H2S) in the gases and vapors from light Mexican crude; (2) the extreme toxicity of H2S; (3) the absence of arsine, stibine, phosgene, hydrocyanic acid, and other toxic substances; (4) treatment recommended for poisoning by H2S; (5) use and limitations of oxygen breathing apparatus, hose masks, and gas masks."

The Minimum Induced Drag of Aerofoils

Description: This report helps explain the phenomenon of flight. It contains some theorems concerning the arrangement of airplane wings which are of considerable practical interest. In particular, it shows the theoretical reasons for the decrease of drag which accompanies all increase in the aspect ratio or lateral extension of a wing. The efficiency of a given arrangement of wings may be calculated from the formulae derived in this paper.

Speed measurements made by Division "A" of the airplane directorate (Flugzeugmeisterei), Subdivision for flight experiments

Description: The various speeds of an airplane can only be measured in horizontal flight, since there are no means for measuring the angle of ascent or descent. The measurements must be corrected for the density of the air. This is obtained by simultaneous pressure and temperature measurements during flight. Calculation from the mean yearly values in accordance with Everling's suggestion can only be considered an approximation, since the distribution of pressure and temperature in the individual strata at different altitudes undergoes such large variations that the yearly mean gives inaccurate values. Thermographs of the present form are useless for temperature measurements of an airplane. In altitude data, the following are to be distinguished: the height above the earth, the barometric altitude, and the altitude corresponding to the yearly mean air density. Variometers are not suited for the mechanical control of high altitude flight.
