Abstract: The circumstances leading to the second phase of the Air-Launched Balloon System Development Program are described, along with the governing design constraints. Individual component development efforts and system design modifications are described in turn: the procurement and testing of the new dewar, the qualification of the updated cryogenic unit recovery system. The complicated command, control, and telemetry subsystem is also described in detail. The results of component tests and a system dress rehearsal system tests are summarized. Preparations for two full-scale system tests conducted in 1981 are covered in considerable detail. The results of those tests are presented and the test data are analyzed. It is concluded that the system's air-launch and mid-air inflation techniques are acceptable. The balloon requires structural reinforcements, however, before the system can be said to be fully developed.

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 from stage to stage). Turbines were tested with water-and-nitrogen mixtures and Refrigerant 22. Nozzle efficiencies were 0.78 (measured) and 0.72 (theoretical) for water-and-nitrogen mixtures at a water/nitrogen mixture ratio of 68, by mass; and 0.89 (measured) and 0.84 (theoretical) for Refrigerant 22 expanding from 0.02 quality to 0.28 quality. Blade efficiencies (shaft power before windage and bearing loss divided by nozzle jet power) were 0.63 (measured) and 0.71 (theoretical) for water-and-nitrogen mixtures and 0.62 (measured) and 0.63 (theoretical) for Refrigerant 22 with a single-stage turbine, and 0.70 (measured) and 0.85 (theoretical) for water-and-nitrogen mixtures with a two-stage turbine.

A report regarding the location of industry drill holes logged in Texas

This report aims to identify the tasks assigned by the OTA and their major sections. The issues of concern to the OTA, and those who make contributions to their discussion, are shown.

This report contains summaries of enactments, treaties, and reorganization plans, passed from 1961 through 1985, that have some clearly indicated relationship-- either by specific reference or by virtue of legislative history--to the Federal effort to prevent drug misuse through control of the supply of narcotics and other dangerous drugs.

Interest in desegregating schools throughout multi-district metropolitan areas has increased as a result of litigation in the Federal courts concerning cross-district integration of students in Detroit, Indianapolis, Louisville, and W Wilmington metropolitan areas. Experience with school desegregation efforts involving a central city school district and its suburban independent school districts is very limited. Throughout the Southeast, school districts generally cover larger geographical areas than in other regions of the Nation. In these districts, various examples can be found of school desegregation efforts involving a central city and its surrounding suburbs; however, these areas have involved only one school district.

Systems that reduce energy usage and are economically viable in the citrus fruit processing industry are identified. The preliminary results of Phase I are presented. Alternative systems to be considered are classified and denoted as central, modular, integrated, and combined. Progress is reported on the central and modular systems. (MCW)

This document addresses basic configurational tradeoffs associated with the SP-100 class of nuclear space power systems. In the SP-100 project, the three reference designs, fallback, baseline, and advanced, employ thermoelectric power conversion with different thermoelectric materials. This issue of the document presents results generated for the thermoelectric design as of the end of 1985. Emphasis is placed on showing general trends and the range of possibilities that could result from selection of a particular design. This document, which reflects efforts on 100-kWe reference designs as of the end of 1985, will be extended and updated to reflect progress in the design studies of the follow-on ground engineering phase for which a 300-kWe size has been selected. THere is a considerable flexibility to the SP-100 power system so that it will generally be most advantageous to tailor it to meet user requirements.

After two generations of almost unchallenged supremacy, the U.S. auto industry has recently faced plummeting sales, rising competition from imports, and mounting requirements for capital investment and structural change. This has resulted in massive spilling of red ink in the industry's profit and loss columns, further financial pressures on the ailing Chrysler Corporation, layoffs of nearly 250,000 workers (as of August 4, 1980 in the automotive industry alone according to the United Auto Workers Union) and soaring claims for unemployment compensation and trade adjustment assistance. This study focuses on import competition in the auto industry and the economic impact of proposals to limit such competition through either import quotas or agreements with foreign governments (Japan) to restrict automotive exports to the United States.
