Design and development of a continuously variable ratio transmission for an automotive vehicle. Phase IV. Quarterly progress report

Progress in the design and development of a continuously variable ratio transmission for an automotive vehicle is reported. The Major automotive hydromechanical transmission development problem continues to be the reduction of hydrostatic noise and the project plan, therefore, concentrated on the new hydrostatic module. The potential for achieving acceptably low noise levels in the second generation hydromechanical transmission is to be assessed by comparing the noise levels of the hydrostatic modules for the first and second generation transmissions. A set of twelve test points was selected comprising of road load steady state and wide-open-throttle acceleration at 10, 20, 30, 40, 50 and 60 mph. The module operating conditions for the two transmissions at each of these twelve points were calculated. Baseline noise data was measured on the first generation module. The results are given testing of co-axial hydrostatic module for second generation hydromechanical transmission will be emphasized. (LCL)

Determination of bulk diffusion lengths for angle-lapped semiconductor material via the scanning electron microscope: a theoretical analysis (open access)

Determination of bulk diffusion lengths for angle-lapped semiconductor material via the scanning electron microscope: a theoretical analysis

A standard procedure for the determintion of the minority carrier diffusion length by means of a scanning electron microscope (SEM) consists in scanning across an angle-lapped surface of a P--N junction and measuring the resultant short circuit current I/sub sc/ as a function of beam position. A detailed analysis of the I/sub sc/ originating from this configuration is presented. It is found that, for a point source excitation, the I/sub sc/ depends very simply on x, the variable distance between the surfce and the junction edge. The expression for the I/sub sc/ of a planar junction device is well known. If d, the constant distance between the plane of the surface of the semiconductor and the junction edge in the expression for the I/sub sc/ of a planar junction is merely replaced by x, the variable distance of the corresponding angle-lapped junction, an expression results which is correct to within a small fraction of a percent as long as the angle between the surfaces, 2 theta/sub 1/, is amaller than 10/sup 0/.

Multilaboratory analytical quality control for the hydrochemical and stream sediment reconnaissance (open access)

Multilaboratory analytical quality control for the hydrochemical and stream sediment reconnaissance

For the first time data received from LLL has been incorporated in the quality assurance report. LASL has indicated that their results on the water standard B2 have been consistently low. They suspect that this may be resulting from uranium plating out in the polyethylene containers. Such an observation has not been made by either ORGDP, SRL or LLL. To evaluate these suspect observations LASL has been sent two sets of standards, one set contained in teflon and the second in the usual polyethylene containers. LASL results for June will be carefully evaluated.

Small power systems study. Volume. Study results. Technical summary report

The Division of Solar Technology of the Department of Energy is currently examining the market potential of a number of dispersed solar energy systems, including the small (less than or equal to 10 MW/sub e/) solar thermal power system. Small fossil-fueled generating units in the United States utility system, (i.e., investor-owned, municipal, and cooperatives) have a current capacity of approximately 8000 MW/sub e/ or about 1.5 percent of the total US electrical capacity, and provide a large potential market for small solar thermal power systems. The Small Power Systems Study has as its objective the determination of conditions under which small (less than or equal to 10 MW/sub e/) solar thermal power units can provide cost-effective electrical power to a variety of users. Potential users, in addition to the utility systems; include Department of Defense installations and applications, remote mining and/or lumbering operations, and other industrial power systems with and without cogeneration. The first year's results on the Small Power Systems Study are summarized. The data base used and the breakeven cost analysis are discussed. Information on both small (less than or equal to 10 MW/sub e/) generating units and the utility systems using them is presented as well as …

Waste Isolation Program. Monthly report (open access)

Waste Isolation Program. Monthly report

In February 1976, the US Energy Research and Development Administration expanded the commercial radioactive waste management programs and established the National Waste Terminal Storage Program. Its mission was to provide multiple facilities in various deep geologic formations within the United States. The Office of Waste Isolation was established within the Union Carbide Corporation-Nuclear Division to provide program management to the National Waste Terminal Storage Program. The overall program consisted of investigating a number of geologic rock types to determine their suitability for terminal storage of radioactive waste. Basalts, such as the Columbia Plateau basalts which underlie a large portion of the Pacific Northwest and the Hanford reservation, were selected for initial geologic reconnaissance. Atlantic Richfield Hanford Company was asked in May 1976 by the Office of Waste Isolation to plan and execute a basalt feasibility study. Geologic exploration of Columbia Plateau basalts was needed to determine the feasibility of utilizing those formations as a site for terminal storage of commercial nuclear waste. In September 1977, the National Waste Terminal Storage Program was restructured. While emphasis was still on a salt repository, additional funds were given to support investigations of two US Department of Energy sites (Hanford and Nevada). Rockwell Hanford …

Tritium waste control: January--March 1978 (open access)

Tritium waste control: January--March 1978

The combined electrolysis-catalytic-exchange pilot system was modified to improve the reliability of the unit for continuous operation. An experimental run for 60 consecutive hours using a single catalytic exchange column was made to estimate values of height of a transfer unit and height equivalent to a theoretical plate for the pilot system. The calculated values were in agreement with existing data from a bench-scale system. Further experiments were performed with the cryogenic hydrogen isotope distillation system, this time using H/sub 2/-HT mixtures. A mixture containing approximately 250 Ci/m/sup 3/ of HT in H/sup 2/ was stripped to less than 0.1 Ci/m/sup 3/, while a product of 1100 Ci/m/sup 3/ was recovered. Two experiments were successful in separating gaseous hydrogen containing tritium from tritiated water. Initial tritium concentrations of the water were approximately 1 and 10 Ci/cm/sup 3/. Radiolytic damage tests of a hydrophobic exchange catalyst being used in the development of a process to recover tritium from tritiated waste water are reported. Triplicate samples of cement, cement-plaster (1:1 ratio by weight), and cement-plaster (1:1 ratio by volume) were injected with 386 Ci of tritium, cured for five days, and then impregnated with catalyzed styrene monomer. After polymerization, the samples were …

Analysis of a radial-outflow reaction turbine concept for geothermal application (open access)

Analysis of a radial-outflow reaction turbine concept for geothermal application

The radial-outflow reaction turbine, a pure-reaction turbine designed to improve the conversion efficiency of geothermal energy into electrical power is described. It also has potential as a total-flow turbine for low-temperature water. The principle of incomplete expansion can be used to obtain a reduction in turbine size when the turbine exhausts into a low-pressure condenser. And, by adding this turbine to single- and two-stage flashed-steam systems, the conversion efficiency of systems utilizing low- and high-energy wellhead sources, respectively can be improved. The Appendix outlines the analysis of the radial-outflow reaction turbine and leads to an expression for engine efficiency.

HP-67 calculator programs for thermodynamic data and phase diagram calculations

This report is a supplement to a tabulation of the thermodynamic and phase data for the 100 binary systems of Mo with the elements from H to Lr. The calculations of thermodynamic data and phase equilibria were carried out from 5000/sup 0/K to low temperatures. This report presents the methods of calculation used. The thermodynamics involved is rather straightforward and the reader is referred to any advanced thermodynamic text. The calculations were largely carried out using an HP-65 programmable calculator. In this report, those programs are reformulated for use with the HP-67 calculator; great reduction in the number of programs required to carry out the calculation results.

A calculation of the cross section for e/sup +/e/sup -/ ..-->.. ..mu../sup +/..mu../sup -/ interactions is performed assuming colliding beam conditions and propagation of a neutral intermediate vector boson. From this a derivation of the expression for the longitudinal polarization of the final state ..mu../sup -/ is made. The calculation, using relativistic, weak interaction, and field theory, demonstrates the connection between the polarization and the weak force parameters explicity. (JFP)
