Report containing information regarding He4 vapor pressure measurement as of 1958, the recent history of the vapor pressure temperature scale, and a series of tables containing these measurements.

From Introduction: "This symposium focuses attention on the growing awareness of the necessity for developing and using better methods for characterizing solids. Many of the most interesting properties of solids depend directly upon these small concentrations of impurities and defects, and the illustration of this is a principal theme of this paper."

From Forward: "Although the first paper in this volume describes the general aspects of the technical management of the program, it is important to emphasize that much of success and productivity of this program stemmed from the sympathetic understanding of its basic viewpoint by both the Department of Defense and the National Bureau of Standards."

"Some of the important results obtained in investigations of capacities of plumbing stacks in test systems at the National Bureau of Standards and elsewhere are discussed. Data are shown from experiments on the flow of water and air in such systems, and analyses of certain flow phenomena are given. Methods are shown for applying the results of research in hydraulics and pneumatics to the preparation of loading tables (for drainage and vent stacks) suitable for use in plumbing codes" (p. 1).

Report discussing "A two-volume table for converting wavelengths in standard air to wavenumbers in vacuum. Wave-numbers are given to the nearest 0.001 K (cm^-1) for wavelengths from 2000 to 7000 A in volume 1, and 7000 A to 1000 m in volume II."

From Abstract: "In the past 60 years considerable data have been accumulated concerning the mechanical properties of copper and its alloys.It was felt that there was great need to adequately document these results in one publication. Therefore a unique type of compilation is presented. The compilation is divided into four parts. The first section is intended for quick reference use for those who are interested in average values. The second section includes data from most of the investigators who have published results on the mechanical properties of copper and its alloys. The third section is composed of tables classifying the investigations which were not in section two. The fourth section section lists, in alphabetical order, all references used."

From Abstract: "This monograph reviews available information on the production, properties, and uses of high-purity and commercial forms of nickel, and on the properties and applications of its important alloys, both ferrous and non ferrous."

From Introduction: "This Monograph has as its purpose the compilation and analysis of the extensive radio refractive index data available within the Central Radio Propagation Laboratory of the National Bureau of Standards. This will be accomplished by presenting both tabulations of basic data for specific locations and charts for interpolation to any location."

Report providing detail measurements and percentages in charts, using three statistical parameters, for amplitude-probability distributions of atmospheric radio noise.

From Abstract: "This treatise is a source document containing information on helium resources, production, conservation, thermodynamic properties, liquefaction and refrigeration techniques, transportation and storage of liquid and safety requirements. It also contains a discussion of uses for liquid and cold gas in cryoelectronics, superconductivity, bubble chambers, cryopumping and missile and space systems."

From Extension of Tables: "Because of its range and size, this table of wavenumbers is in two volumes, Volume I presenting wavenumbers for all wavelengths between 2000 and 7000 A, and Volume II giving wave-numbers for all wavelengths from 7000 A to 10000000 A=1 mm. In some cases Volume I may suffice for ionic spectra, and in others Volume II may be adequate for molecular spectra, but in general both volumes will needed to cover the entire range of spectral wavelengths measured in standard air."
