Vacuum-Freezing Vapor-Compression Desalting Process

Description: From Abstract: "The Vacuum-Freezing Vapor-Compression Process (VFVC) was evaluated during the period from February, 1965, through March, 1967, by Colt Industries Inc. under O.S.W. Contract No. 14-01-0001-532." From Process Description: "The primary principles involved for converting of sea and brackish water to fresh water in the VFVC Process are rather well known in physical chemistry and are summarized below. The principles discussed above, applied to a practical VFVC desalting system, are il… more

Oscillator Strengths and Transition Probabilities fro 3288 Lines of Fe I

Description: Report of a homogeneous set of intensity-related data calculated for 3288 spectral lines of Fe I in the region from 2100 to 9900 angstroms. The quantities tabulated in the present monograph include log (g__), log (gf), gf,f,gA, and A. Since recent investigations do not support excitations corrections in the case of Fe I and certain other spectra, the present tabulation incorporates a removal of that normalization function. This recalculation affects the values for all lines whose upper energy l… more

Geodimeter Measurement of Earth Strains on Rainier Mesa, Nevada Test Site

Description: Abstract: "Geodimeter surveys were made on four traverses near the east scarp of Rainier Mesa between October 27, 1967 and April 26, 1968. These measurements were made in order to determine if an changes in distance between survey stations had resulted from downslope creep of the rocks behind the scarp, or if any displacements had resulted from nuclear explosions beneath the mesa and in adjacent areas. A persistent small but possibly significant, slopeward displacement was measured along one tr… more

Cosmic Ray Produced Ar37 and Ar39 Activities in Recently Fallen Meteorites

Description: Several methods of determining meteorite ages depend ages upon nuclides formed by cosmic ray interactions. The tactic assumption is always made that the intensity of cosmic radiation does not vary in time or space. However it is known that the intensity of cosmic radiation at the earth varies with the solar activity. The spectrum of cosmic ray protons and alpha particles exhibit a marked drop at the low energy end (<1.5 GeV) and the intensity in the region appears to follow the 11 year cycle of… more

An Ultrasonic System for Testing Isotope Heat Capsules

Description: Introduction: This report describes a program to develop a nondestructive (ultrasonic) tester and testing procedure to perform integrity tests on isotope heat source containers. The increased application of isotope heat sources has brought more attention to the engineering problems encountered during fabrication. One of the most important of these problems is insuring the isotope containment during the long unattended periods of use. To determine the integrity of the heat source container, a no… more
