Contributions to the Data on Theoretical Metallurgy: [Part] 3. The Free Energies of Vaporization and Vapor Pressures of Inorganic Substances

Description: From Introduction: "It is the purpose of this present work (1) to apply the previously compiled entropy values and specific-heat equations to vapor-pressure and other pertinent data in obtaining heat and free energy of vaporization equations for inorganic substances valid up to the normal boiling or sublimation points (760 mm pressure), (2) to supplement wherever possible the data on heats and entropies of transformations and fusions, (3) to supplement wherever possible the data on heats and entropies of gases, and (4) to supply tables of vapor pressures for inorganic substances at various temperatures up to and including the boiling or sublimation point."

Contributions to the Data on Theoretical Metallurgy: [Part] 4. Metal Carbonates--Correlations ans Applications of Thermodynamic Properties

Description: From Introduction: "This publication proposes to assemble existing thermodynamic data for carbonates and to correlate so far as possible the results of decomposition-pressure determinations with the calorimetrically determined heats of formation and entropy values on the one hand and with solubility and standard electrode-potential data on the other."

Engineering Factors in the Ventilation of Metal Mines

Description: From Introduction Purpose and Scope of Report: "In the belief that the quickest and cheapest method of obtaining effective ventilation of metal mines with regard to air conditions that promote efficiency, health, and safety is through more general application of the engineering factors involved rather than by trial and error and this method of attacking ventilation problems will be facilitated by a simple, concise statement of these factors and the methods of using them, an attempt is made in this bulletin to present the subject of metal-mine ventilation to mine operators in a practical way."
