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.

Third Report on Horizontal-Tube Multiple-Effect Process Pilot Plant Tests

Description: From Summary: "This report describes the continuing work on HTME distillation plants, the first portions of which were reported in References 1 and 2. A major purpose in the testing of the three-effect pilot plant was to demonstrate mutiple-effect operability of the the horizontal tube method, when utilizing basically the same construction methods and materials as those proposed for commercial HTME plants."

Deflection-Coverage Relationship for Flexible Pavements

Description: Summary: "This study was conducted for the purpose of developing a relationship between elastic pavement deflection and pavement performance (number of traffic applications necessary to cause failure). Data for the study were taken from past studies of airfield and highway pavements. A summary of test conditions, failure criteria, and traffic type is given for each data source. A relationship was developed between elastic deflection and the number of coverages of traffic for combined airfield a… more

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 … more

Seawater Tubular Reverse Osmosis Membranes

Description: From Introduction and Summary: "The objective of this program was to improve the quality, performance, and useful life of seawater tubular reverse osmosis membranes. The secondary objective was the evaluation of defect-free membranes in a small module with both sodium chloride and with actual seawater."

Shock-Absorbing Materials, Report 2: Cellular Concrete as a Backpacking Material

Description: Partial abstract: "The use of low-density cellular concrete, having an oven-dry unit weight of 50 pcf or less, as a backpacking material for deeply buried protective structures was studied. Cellular concrete was found to be suitable for this type of application. A number of physical properties of cellular concrete were determined to provide input to design codes" (p. 4).

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 pr… more

Trafficability of Soils: Effects of Surface Conditions on Drawbar Pull of a Wheeled Vehicle

Description: "A study was conducted to (a) investigate the effects of soil surface conditions on one-pass drawbar pull capabilities of a wheeled vehicle, (b) relate optimum drawbar pull to soil strength as measured by several instruments, (c) develop tentative equations for predicting optimum tractive coefficient, and (d) determine effects of tire characteristics (tread pattern and deflection) on drawbar pull. One hundred and six drawbar pullslip tests were conducted with a 3/4-ton M37 truck at a gross weig… more

Transport-Depletion Desalination Pilot Plant

Description: From Summary: "The transport-depletion data obtained by the Southern Research Institute and by the Bureau of Reclamation at Denver, Colorado and at Webster, South Dakota, was reviewed. This data review made it possible to develop a design methodology for the pilot plant, and to identify the additional data required to adequately predict the performance of a transport-depletion stack."

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 … more
