Abstract: Theoretical and experimental work on the fluid dynamics of physical vapor transport is reported. It is shown that diffusion in viscous interaction with container walls leads to concentration gradients normal to the main ... NASA Center: NASA (non Center Specific) Publication Year: 1979 Added to NTRS: 2008-11-05 Accession Number: 82N32078; Document ID: 19820024202 Binary sequential ranging with sine waves Author(s): Martin, W. L.; Layland, J. W. Abstract: Current ranging systems of the deep space network estimate the range to a spacecraft by measuring the phase of a square wave range code after its roundtrip from station to spacecraft and back. Distortion of this waveform, in ... NASA Center: Jet Propulsion Laboratory Publication Year: 1976 Added to NTRS: 2008-11-05 Accession Number: 76N18169; Document ID: 19760011081 Fluid devices Author(s): Scroop, R. Abstract: Rolamite performance as a valve is discussed. Operating characteristics of the valve in the absence of lubricants or at extreme temperatures were considered. Advantages of the valve, including high sealing and low actuating ... NASA Center: NASA (non Center Specific) Publication Year: 1969 Added to NTRS: 2008-11-05 Accession Number: 76N19451; Document ID: 19760012363 Formation of metallic and metal hydrous oxide dispersions Author(s): Matijevic, E.; Sapieszko, R. S. Abstract: The formation, via hydrothermally induced precipitation from homogeneous solution, of a variety of well-defined dispersions of metallic and hydrous metal in the conditions under which the particles are produced (e.g., pH and ... NASA Center: NASA (non Center Specific) Publication Year: 1979 Added to NTRS: 2008-11-05 Accession Number: 82N32065; Document ID: 19820024189 Theory and force generation Author(s): Bell, L. E. Abstract: Force generation and its source in self contained non-suspension rolamite devices and in suspension type devices are investigated. Special attention was given to force generated by nonparallel guides. NASA Center: NASA (non Center Specific) Publication Year: 1969 Added to NTRS: 2008-11-05 Accession Number: 76N19456; Document ID: 19760012368 Manufacturing processes Author(s): Gardiner, B. S. Abstract: The rolamite manufacturing process, particularly band and contact fabrication is described. Parts assembly and roller and case fabrication are included. Inspection and environmental tests of the units are discussed.

E.; Huang, S. C. Abstract: A review is presented of the major experimental findings obtained from recent ground-based research conducted under the SPAR program. Measurements of dendritic growth at small supercoolings indicate that below approximately ... NASA Center: NASA (non Center Specific) Publication Year: 1979 Added to NTRS: 2008-11-05 Accession Number: 82N32075; Document ID: 19820024199 Some potential blood flow experiments for space Author(s): Cokelet, G. R.; Meiselman, H. J.; Goldsmith, H. L. Abstract: Blood is a colloidal suspension of cells, predominantly erythrocytes, (red cells) in an aqueous solution called plasma. Because the red cells are more dense than the plasma, and because they tend to aggregate, erythrocyte ... NASA Center: NASA (non Center Specific) Publication Year: 1979 Added to NTRS: 2008-11-05 Accession Number: 82N32068; Document ID: 19820024192; Report Number: UR-3490-1720 Flying by Ear: Blind Flight with a Music-Based Artificial Horizon Author(s): Simpson, Brian D.; Brungart, Douglas S.; Dallman, Ronald C.; Yasky, Richard J., Jr.; Romigh, Griffin Abstract: Two experiments were conducted in actual flight operations to evaluate an audio artificial horizon display that imposed aircraft attitude information on pilot-selected music. The first experiment examined a pilot's ability ...
