Convective and morphological instability in vapor crystal growth
Author(s): Rosenberger, F.
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 ...

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 ...

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 ...

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 ...

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.

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.

Convective flow during dendritic growth
Author(s): Glicksman, M. 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 ...

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 ...

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 ...

Design of a superconducting cavity stabilized maser oscillator
Author(s): Higa, W.
Abstract: The possibility of using a superconducting cavity to stabilize a microwave oscillator is elaborated. The achievement of cavity Qs of the order of 10 to the 10th power has made possible the realization of frequency standards ...
