Helical Screw Expander Evaluation Project. Final report

Description: A functional 1-MW geothermal electric power plant that featured a helical screw expander was produced and then tested in Utah in 1978 to 1979 with a demonstrated average performance of approximately 45% machine efficiency over a wide range of test conditions in noncondensing operation on two-phase geothermal fluids. The Project also produced a computer-equipped data system, an instrumentation and control van, and a 1000-kW variable load bank, all integrated into a test array designed for operat… more

Energy conservation in citrus processing. Technical progress report, October 1, 1979-March 31, 1980

Description: The Sunkist Citrus Plant in Ontario, California, processes about 6 million pounds of citrus fruit per day to make products which include frozen concentrated juice; chilled, pasteurized, natural strength juice; molasses from peel; dried meal from peel; pectin; citrus oil; and bioflavonoids. The energy intensive operations at the plant include concentration, drying, and refrigeration. The objective of the two-year two-phase project is to identify an economically viable alternative to the existing… more

Theory and tests of two-phase turbines

Description: Two-phase turbines open the possibility of new types of power cycles operating with extremely wet mixtures of steam and water, organic fluids, or immiscible liquids and gases. Possible applications are geothermal power, waste-heat recovery, refrigerant expansion, solar conversion, transportation turbine engines, and engine bottoming cycles. A theoretical model for two-phase impulse turbines was developed. Apparatus was constructed for testing one- and two-stage turbines (using speed decrease fr… more

Dual arm master controller development

Description: The advanced servomanipulator (ASM) slave was designed with an anthropomorphic stance, gear/torque tube power drives, and modular construction. These features resulted in increased inertia, friction, and backlash relative to tape-driven manipulators. Studies were performed which addressed the human factors design and performance trade-offs associated with the corresponding master controller best suited for the ASM. The results of these studies, as well as the conceptual design of the dual arm m… more

Low Energy X-Ray Spectra Measured With a Mercuric Iodide Energy Dispersive Spectrometer in a Scanning Electron Microscope

Description: A mercuric iodide energy dispersive x-ray spectrometer, with Peltier cooling provided for the detector and input field effect transistor, has been developed and tested in a scanning electron microscope. X-ray spectra were obtained with the 15 keV electron beam. An energy resolution of 225 eV (FWHM) for Mn-K/sub ..cap alpha../ at 5.9 keV and 195 eV (FWHM) for Mg-K line at 1.25 keV has been measured. Overall system noise level was 175 eV (FWHM). The detector system characterization with a carbon … more

Refractory materials for high-temperature thermoelectric energy conversion

Description: Theoretical work of two decades ago adequately explained the transport behavior and effectively guided the development of thermoelectric materials of high conversion efficiencies of conventional semiconductors (e.g., SiGe alloys). The more significant contributions involved the estimation of optimum doping concentrations, the reduction of thermal conductivity by solid solution doping and the development of a variety of materials with ZT approx. 1 in the temperature range 300 K to 1200 K. It was… more

An Investigation of the Needs for Music-Related Content in the Bible College Pastoral Curriculum as Perceived by a Selected Group of Pastors

Description: The purpose of the study was to investigate the needs for music-related content in the Bible college pastoral curriculum as perceived by a selected group of pastors. The research problems were (1) to assess the extent of musical preparation of recent pastoral graduates from selected accredited Bible colleges in the United States, (2) to assess the music-related duties of those graduates in paid pastoral positions, (3) to assess the pastors' perceived needs for instructional preparation for the … more

A Study of the Factors Related to Planned and Actual Manufacturing Lead Time in Two Environments: (1) High-Volume Continuous-Production and (2) Job-Shop Production-to-Order

Description: This study focused upon the manufacturing lead time management in California's electrical and electronic machinery, equipment, and supplies industry. Manufacturing firms with one hundred or more employees were invited to participate in the research. Six subproblems relating to manufacturing lead time were selected and six appropriate null hypotheses were tested. The subproblems identified (1) factors influencing manufacturing lead time, (2) production planning processes influencing manufacturin… more

California-ko Ostatuak: a History of California's Basque Hotels

Description: The history of California's Basque boardinghouses, or ostatuak, is the subject of this dissertation. To date, scholarly literature on ethnic boardinghouses is minimal and even less has been written on the Basque "hotels" of the American West. As a result, conclusions in this study rely upon interviews, census records, local directories, early maps, and newspapers. The first Basque boardinghouses in the United States appeared in California in the decade following the gold rush and tended to be o… more

When Patients Threaten to Kill: A Texas View of Tarasoff

Description: A serious problem confronts the psychologist whose patient threatens, within the privacy of a therapy session, to inflict violent harm upon some third person. Therapists in Texas face a risk of unjust legal liability because of a lack of widely accepted, clearly and fully articulated standards. A questionnaire was submitted to Texas psychologists and Texas judges of mental illness courts. It involved a hypothetical case of a patient who threatened to kill his girlfriend. The hypothesis that no … more

Four absolute cavity radiometer (pyrheliometer) intercomparisons at New River, Arizona: radiometer standards

Description: Four detailed intercomparisons were made for a number of models of cavity-type self-calibrating radiometers (pyrheliometers). Each intercomparison consisted of simultaneous readings of pyrheliometers at 30-second intervals in runs of 10 minutes, with at least 15 runs per intercomparison. Twenty-seven instruments were in at least one intercomparison, and five were in all four. Summarized results and all raw data are provided from the intercomparisons.

Interplanetary propulsion using inertial fusion

Description: Inertial fusion can be used to power spacecraft within the solar system and beyond. Such spacecraft have the potential for short-duration manned-mission performance exceeding other technologies. We are conducting a study to assess the systems aspects of inertial fusion as applied to such missions, based on the conceptual engine design of Hyde (1983) we describe the required systems for an entirely new spacecraft design called VISTA that is based on the use of DT fuel. We give preliminary design… more
