Compilation of the Melting Points of the Metal Oxides (open access)

Compilation of the Melting Points of the Metal Oxides

Report compiling the melting points of 70 metal oxides published prior to January 1963. Both the original melting point and the equivalent value based on the International Practical Temperature Scale of 1948 are presented. Included in the survey is information on pertinent experimental details such as the method of temperature measurement, purity, furnace type, and environmental conditions.

Systems of Electrical Units (open access)

Systems of Electrical Units

Report issued by the U.S. National Bureau of Standards discussing different systems of electrical units. As stated in the introduction, "the various systems of measurement, with their respective sets of units, used in the literature on electricity and magnetism are described in detail" (p. 1). This report includes tables.

Tensile and Impact Properties of Selected Materials From 20 to 300 ºK (open access)

Tensile and Impact Properties of Selected Materials From 20 to 300 ºK

Report giving the tensile and impact properties of structural materials that were experimentally determined at temperatures from 20 to 300 ºK. Tensile properties of a few materials were also determined at 4 ºK. The properties experimentally determined were the yield strength, tensile strength, elongation, and reduction of area, the stress versus strain curve, and the impact energy. The test equipment and procedures are described. The individual data are presented in tables, and the average results are displayed in graphs.

Reduction of Data for Piston Gage Pressure Measurements (open access)

Reduction of Data for Piston Gage Pressure Measurements

Report issued by the U.S. National Bureau of Standards discussing piston gage pressure and reducing errors of measurement. Sources of error are described and evaluated in order to "reduce the magnitude of overall error of measurement" (p. 1). This report includes tables, and illustrations.

Reduction of Data for Piston Gage Pressure Measurements (open access)

Reduction of Data for Piston Gage Pressure Measurements

Report discussing pressure measurements made with piston gages that are affected by gravity, temperature, pressure, and several other variables. For accurate determinations of pressure the calculations must take these variables into account. A general equation is developed and simplified procedures for calculating pressure are illustrated.

Refractive Indices and Densities of Aqueous Solutions of Invert Sugar (open access)

Refractive Indices and Densities of Aqueous Solutions of Invert Sugar

Report of the refractive indices and densities of aqueous solutions of invert sugar at temperatures of 15, 20, 25, and 30º C, for concentrations up to about 82 percent of invert sugar (by weight). From the results, equations have been derived which relate the refractive index and percent of invert sugar (weight in air) at each temperature. Other equations relate the absolute density and percent of invert sugar (weight in vacuum) at each temperature. Five-decimal tables giving the refractive indices and densities of invert sugar solutions containing 1 to 85 percent of sugar are given for each percentage of invert sugar at the four temperatures.

Standard X-ray Diffraction Powder Patterns: Section 2. Data for 37 Substances

Report documenting standard x-ray diffraction powder patterns for various compounds, intended to replace previous data or provide information for new substances. It describes the methods and, for each substance, outlines any previous data as well as information about the sample used and structural data, with a table of diffraction patterns.

Influence of a Sector Ground Screen on the Field of a Vertical Antenna (open access)

Influence of a Sector Ground Screen on the Field of a Vertical Antenna

Report show the field of a short vertical antenna on a homogeneous ground is modified by the presence of a metallic screen. The screen is taken in the form of a circular disk and a concentric sector. The modification of the field is expressed in the form of surface integrals over the disk and the sector. Extensive numerical results for these basic integrals are given and a number of applications are illustrated.
