Causes of Variation in Chemical Analyses and Physical Tests of Portland Cement

Causes of Variation in Chemical Analyses and Physical Tests of Portland Cement

Date: April 27, 1961
Creator: Bean, B. Leonard & Dise, John R.
Description: Report discussing variations in comparative tests of portland cements that could lead to the rejection of a material fully conforming to specification requirements, or the acceptance of a material with undesirable chemical or physical properties. Many of the causes for variation in chemical analyses and physical test results are listed in this discussion, and remedies for some of the more frequently encountered deficiencies in apparatus and methods are suggested.

Colors of Signal Lights: Their Selection, Definition, Measurement, Production, and Use

Colors of Signal Lights: Their Selection, Definition, Measurement, Production, and Use

Date: April 3, 1967
Creator: Breckenridge, F. C.
Description: Report discussing the selection, specifications, and use of signal-light colors. It discusses the nature of the problem, and the mathematical representation, recognition, production, control, and use of such colors. The characteristics of different types of chromaticity boundaries and the purpose and effect of the requirement for similarity of chromaticity characteristics are given special consideration. The treatment is varied according to the intended use. The discussion of the control of colors and the section on the use of colors are nontechnical, whereas the section on the production of signal colors is designed for the colorimetrist who is faced with the problem of selecting limit filters or drafting a specification.

Compilation of the Melting Points of the Metal Oxides

Compilation of the Melting Points of the Metal Oxides

Date: October 10, 1963
Creator: Schneider, Samuel J.
Description: 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.

A Complete Mode Sum for LF, VLF, ELF Terrestrial Radio Wave Fields

A Complete Mode Sum for LF, VLF, ELF Terrestrial Radio Wave Fields

Date: October 1, 1964
Creator: Johler, J. Ralph & Berry, Leslie A.
Description: Report discussing the VLF, ELF propagation in the earth-ionosphere waveguide emphasizing the total field found by summing all modes which contribute appreciably. Solutions are given and calculations are made for a homogeneous isotropic ionosphere, a homogeneous ionosphere with a constant radial magnetic field imposed, and an ionosphere with a magnetic field of arbitrary dip angle.
