Development Report Number 9: V.T.E. Process Development, Freeport Test Facility, Freeport, Texas

Description: Report presenting accounts of testing saline water conversion and the economics thereof. This report covers the fifteenth and sixteenth Development Runs, which evaluated the following: the performance of the plant's double-fluted tube bundle and titanium tube bundle; the condensate handling-restrictions in the 5 effect module; a sump to sump brine transfer system modification; porcelain spray nozzles; enhanced surface tubes; and an oxygen scavenging system.

The Effect of Time Ordering on the Lyman α Profile

Description: Report investigating the effects of time-ordering over the complete line profile using a unified theory of spectral line broadening previously developed. The behavior of the time-ordered thermal average and un-time-ordered thermal average are compared. The Fourier transform of the thermal average is obtained analytically. Calculations for the line profile of the Lyman-[functional symbol alpha] line of hydrogen are presented and are representative in that the full thermal average is replaced by the thermal average with the electron velocity distribution approximated by f(v)=[functional symbol alpha] (v-vav) where vav is the thermal velocity for the plasma in question.

A High-Dispersion Spectral Analysis of the Ba II Star HD 204075 (ζ Capricorni)

Description: Report discussing a double differential curve of growth analysis for the Ba II star S Capricorni. Both the sun and � Virginis (G9 II-III) were used as comparison stars. The observational material consists of equivalent widths, central depths, and half-widths for 1100 spectral lines measured on direct-intensity tracings of plates obtained by J. L. Greenstein at the coude focus of the 200-in telescope. The plates cover the spectral regions 3880-4825 A and 5100-6720 A at reciprocal dispersions of 2.3 and 3.4 A/mm, respectively. Atmospheric abundances have been derived for 37 elements.

Intake Systems for Desalting Plants

Description: From Forward: "This is one of a continuing series of reports designed to present accounts of progress in saline water conversion and the economics of its application. Such data are expected to contribute to the long-range development of economical processes applicable to low-cost demineralization of sea and other saline water."

Operation of the Multi-Effect Multi-Stage Flash Distillation Plant (Clair Engle), Fourth Report (Semi-Annual), San Diego, California

Description: From Summary, Conclusions, and Recommendations: "The operation and development programs carried out in the CEP, E-1A and LMC plant during the period July 1, 1970 to December 31, 1970 are described in this report. Data was developed on several development tasks as follows. A summary is presented of material evaluation studies made over the past three and a half years. Data on the experiences with coatings, mortar linings, elastomers, and nonferrous and ferrous metals are included. Details are presented of coatings and linings installed in the CEP II Effect including methods of surface preparation and costs."
