The Status of Meteorological Knowledge as a Factor in Air Pollution Control (open access)

The Status of Meteorological Knowledge as a Factor in Air Pollution Control

The first national Technical Conference on Air Pollution (1) held in this city in 1950 included eight papers on meteorology; the present session contains one. On this basis, one night conclude that recent progress in meteorology has been virtually nonexistent or that the importance of meteorological factors has been diminishing, Neither could be further from the truth, as the number and quality of papers relating to air pollution meteorology in recent scientific and technical sessions will attest. It is particularly appropriate to review the status of meteorological "know-how" at this time, because of the many situations in which the ultimate capability of the atmosphere to absorb pollution is in question. Both in connection with highly toxic materials on the one hand and the "megalopolis" on the other, estimates of the "atmospheric sewer capacity" are becoming increasingly necessary to industrial and municipal planning.

A Study of the Disposal of the Effluent From a Large Desalination Plant (open access)

A Study of the Disposal of the Effluent From a Large Desalination Plant

From Introduction and Summary and Conclusions: "The disposal of the effluents from large desalination plants has been studied for two years by the Dow Chemical Company and Texas A. & M. University under contract to the Office of Saline Water. Recommendations are presented on the type, frequency, and intensity of pre-plant oceanographic and biological surveys and of post-plant monitoring and verification surveys."

Tunneling Technology: Its Past and Present

Report issued by the U.S. Bureau of Mines discussing tunneling technology for mine development. As stated in the introduction, "the discussion is based primarily upon tunnels driven through relatively competent rocks for mine development and drainage; public water supply; canal, railway, and vehicular transportation; and hydroelectric facilities. Special tunneling methods using shields and compressed air in soft ground are not described" (p. 1). This report includes a table.

Vacuum-Freezing Vapor-Compression Desalting Process (open access)

Vacuum-Freezing Vapor-Compression Desalting Process

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 illustrated in the schematic flow diagram, Figure 3. This simplified diagram shows both the essential components of the process and the flow paths of the various fluids in the system. A typical mass and heat balance is shown in Figure 4."
