Report issued by the National Bureau of Standards over low voltage electric thermostats. Thermostat test results are discussed. This report includes illustrations, and photographs.

Quarterly report discussing fuel cell research and development work at Argonne National Laboratory (ANL). This report describes efforts directed toward (1) improving understanding of component behavior in molten carbonate fuel cells and (2) developing alternative materials and concepts for components. The principal focus was changed during this period from the development of cathodes fabricated from NiO and electrolyte supports of sintered y-LiA102 to an investigation of NiO cathode dissolution and deposition and a search for alternative cathode materials.

As part of the Solar Reliability and Materials Program at Argonne National Laboratory, the atmospheric corrosion of candidate batten and enclosure materials were tested on outdoor racks parallel to the tilted solar-collected panels at nine National Solar Data Network (NSDN) sites, located in mild marine, mild industrial, and rural environments. The candidate materials evaluated include galvanized steel (G-90), aluminized steel (Type 2), aluminum (6061), and white polyester painted steel. Data analyses predicted that all the first three materials will last more than 20 years in the nine sites tested. However, repainting of the painted steel is probably needed within five years in a mild marine environment and five to ten years in a mild industrial or rural environment.

As part of the Solar Reliability and Materials Program at Argonne National Laboratory, metal corrosion associated with thermal cycling at 82 C circulating and 176 C stagnating temperatures of propylene glycol and ASTM corrosive water mixture (50% v/o) was investigated. Preliminary data indicate that in a mixed metal system of copper, steel, and aluminum specimens stagnating together in a glycol solution, the copper randomly pits and the pitting stops when the pit depth extends to about 1-1/2 mil. The addition of 1% molybdate as an inhibitor to the glycol solution is slightly beneficial for steel, but the added expense of adding and maintaining the concentration of an inhibitor may not be warranted. Dissolved copper rapidly deposits on the aluminum surface and promotes severe galvanic corrosion.

This report describes the current state of the utility subroutine package used with codes being developed by the staff of the Applied Physics Division. The package provides a variety of useful functions for BCD input processing, dynamic core-storage allocation and management, binary I/O and data manipulation. The routines were written to conform to coding standards which facilitate the exchange of programs between different computers.

From abstract: Tests were conducted on a 1:40-scale model of Big Creek to investigate the hydraulic performance of a proposed floodway channel and a section of a modified channel.

Abstract: This paper describes the theory of a single sensor to perform simultaneous electric and magnetic near-field measurements. The theory indicates that it is possible to obtain the magnetic-loop and electric-dipole currents using a loop terminated with identical loads at diametrically opposite points. The theory also indicates that it is possible to obtain an ideal load impedance for achieving equal electric and magnetic field responses of the loop. Preliminary experiments have been performed using plane waves to verify these results. Key words: electric field, electromagnetic interference, electromagnetic radiation, loop, magnetic field, near fields.

Scope: This report summarizes part of the hydrologic data needed to determine the effects of streamflow on ground-water storage. The report includes (1) streamflow data at selected points between the water-conservation reservoirs on the Salt and Verde Rivers and the Gila River as Gillespie Dam, (2) changes in ground-water levels in 169 observation wells from February 1978 to May 1980, (3) an estimate of the streamflow losses along the Salt and Gila Rivers between Granite Reef and Gillespie Dams from March 1978 to June 1980, and (4) the infiltration rates on May, 9, 1979, for the Salt River downstream from Granite Reef Dam. Most of the hydrologic data in this report are available in computer-printout form and may be consulted at U.S. Geological Survey offices in: Federal Building, 301 West Congress Street, Tucson, and Valley Center, Suite 1880, Phoenix. Copies of the data can be obtained at private expense.

From abstract: This report documents the results of rating analyses based on linear multiple regression for ice-covered periods of flow at 33 stations on selected rivers in Maine. The report also presents functions relating uncertainties in records to the number of discharge measurements made at 54 stations.

From purpose and scope: The purpose of this report is to present biological data and to compare the physical, chemical, and biological data to water-quality criteria that are desirable for the proposed reservoir uses.

From purpose and scope: The purpose of this study is to describe water-quality conditions in Shasta Lake and in major tributaries to the lake. The study involved the collection and interpretation of historical, hydrologic, and water-quality data collected during intensive and routine monitoring efforts.

From purpose and scope: The purpose of this report is to summarize and evaluate fluvial-sediment data collected in the study area by the U.S. Geological Survey. The principal products of this report are sediment concentration and load statistics, sediment-transport curves, calculated mean annual sediment yields at selected stations, and an areal sediment-yield map. A secondary purpose is to describe sediment relationships between stations and basins and to identify environmental factors that are important in determining sediment yield.

From introduction: The purpose of this report is to describe the channel-geometry technique and to present equations for estimating mean annual runoff and peak flows for ungaged streams in southeastern Montana.
