The results of the flotation tests conducted demonstrate that the use of fine colloidal gas aphrons (CGA) bubbles is beneficial for fine coal flotation. As demonstrated with the ultrafine coal sample, the froth products of CGA flotation are almost twice as clean as those of the conventional flotation tests at 70% yield. The kerosene consumption was considerably higher, however, both in conventional and in CGA flotation. Attempts were made to coat the CGA bubbles with a film of kerosene and use them for flotation, hoping that this would reduce the oil consumption. However, no positive results have yet been obtained with this process. Another problem associated with CGA flotation is that the ash content of the froth products is relatively high when using a stable CGA, such as that prepared with Dowfroth M150. On the other hand, when using an unstable CGA, as is the case with MIBC, low ash clean coal products can be obtained, but at the expense of the yield. Two approaches are being investigated to correct this problem. A considerable amount of effort has been made to determine the surface charge of the CGA.

The purpose of this project was to design and build 19 solar thermosiphoning air panels, insulate walls, generally tighten up the library building, and install other energy conserving devices. Another purpose of the project was to serve as a model to other libraries in Kentucky, to commercial buildings in this area, and to homeowners in the area. After much discussion with architects and among ourselves, we chose a type of solar installation that would be visible to the public and easily replicated. We also carried out a number of procedures to make the library building more energy efficient: installed a 7-day programmable setback thermostat; insulated the walls; improved weatherstripping around the doors; added an economizer control to our air-handling system; and put an electric damper controlling supply air to a large but intermittently usedmeeting room. These changes resulted in approximately $700 in savings from December 1981, through February 1982. Thus far, we have carried out public education with a sign, brochures, press releases, and the purchase of appropriate books; librarians have received our brochure, and some have attended a workshop given here on energy conservation and solar energy.

This paper describes the QA and QC efforts and results used in fabricating the superconducting magnets of competing designs being developed by American Manufacturers for testing in the ORNL Large Coil Test Facility. Control of the design, materials and processes to assure proper functioning of the magnets in the test facility as well as the content of archival data being compiled is discussed.

The most consistent pulmonary-function change attributed to carnotite uranium-ore-dust exposure (at 15 mg/m/sup 3/, for 4 h/day, 5 days/week) is an increased slope of the single-breath N/sub 2/ washout curve, suggesting an uneven distribution of ventilation. This change was observed in dogs exposed for less than 1 year and continued through 4 years of exposure. Measurements of pulmonary resistance, after 27, 40 and 47 months exposure, showed slight age-related changes and increasing differences between control and exposed animals with duration of exposure. These two changes are suggestive of a bronchitic response, similar to the industrial bronchitis of mine workers. The most notable pulmonary lesions observed in dogs exposed for up to 4 years are: vesicular emphysema, peribronchiolitis and focal pneumoconiosis. Lesions of the major airways and upper respiratory tract, when present, were minimal in severity. Pulmonary vesicular emphysema was present in all but one of the examined dogs. The emphysema was dose-related, in that it was present only to a slight degree in dogs exposed for less than 3 years and, thereafter, increased in severity. Morphometric measurement data confirmed the value of the histopathologic grading system for the degree of emphysema. These data correlated best with the dynamic pulmonary compliance …

Process solvent (PS) and solid product (dissolved in organic solvent) produced by the Solvent Refined Coal (SRC-I) process at the Wilsonville pilot plant contain mutagenically active components against the Ames-Salmonella strains, Salmonella typhimurium TA98 and TA100. Ames-positive mutagens are apparently concentrated in the moderately polar to strongly polar chemical constituents of both materials. However, the dissolved solid product contains a much higher proportion of very strongly polar mutagens, and may be enriched in acidic - i.e., oxygen-containing mutagens.

An attempt is made to determine the sources that are responsible for producing geothermal anomalies observed within the southern Black Hills region. Lithologic and structural boundaries residing in the upper crust and their relationship to the geothermal system are discussed. A regional gravity survey was supplemented by a regional aeromagnetic survey.

This report summarizes the techniques and procedures used to handle automated data collected at the University of Minnesota-Duluth (UMD) campus coal gasification facility. This facility, which is partially funded by the Department of Energy, is being evaluated by scientists at Oak Ridge National Laboratory (ORNL) for its potential health and environmental effects. Automatic data collections and manually collected and sample results data are used for this assessment. A data management project at ORNL handles these and other UMD data for the Gasifiers in Industry Program (GIIP). Specifically, this report documents the procedures developed within the data management project for handling two categories of automated data: (1) process and (2) environmental. The examples included use actual data from the first one and a half years of gasifier operation.
