Santa Ana Fire Department Experiment at 1315 South Bristol, July 14, 1994. Report of Test.

August 31, 1994
Author(s)
Anthony D. Putorti Jr., William D. Walton, W H. Twilley, Scott Deal, J. C. Albers
The Santa Ana Fire Department of Santa Ana, California conducted a series of fire experiments in residences on South Bristol Street in the city of Santa Ana in July, 1994. NIST provided technical support, consisting of measurements of fire phenomena, to

Upward Flame Spread on Composite Materials

August 28, 1994
Author(s)
Thomas J. Ohlemiller, Thomas G. Cleary
The composite materials of interest in this work contain several piles of long, high strength fibers, typically woven in some fixed pattern; the layered multi-ply structure is embedded with an organic polymer resin. Such composites offer a high strength-to

Acid Gas Production in Inhibited Propane-Air Diffusion Flames

August 21, 1994
Author(s)
Gregory T. Linteris
The proposed replacements to halon 1301, mainly fluorinated and chlorinated hydrocarbons, are expected to be required in significantly higher concentrations than CF3Br to extinguish fires. At these higher concentrations the by-products of the inhibited

Compatibility of Halon Alternatives During Storage

August 21, 1994
Author(s)
Richard G. Gann, Carlos R. Beauchamp, Thomas G. Cleary, J L. Fink, Richard H. Harris Jr., F Horkay, G B. McKenna, Thomas P. Moffat, Marc R. Nyden, Richard D. Peacock, Richard E. Ricker, Mark R. Stoudt, W. K. Waldron
A key facet of the evaluation of new fire suppressants is their behavior under pressure and at elevated temperature in a metal storage container with an elastomer seal. In this study, 13 candidate chemicals have been examines: C2F6, C3F8, C4F10, cyclo-C4F8

Flammability Properties of Honeycomb Composites and Phenol-Formaldehyde Resins

August 21, 1994
Author(s)
Marc R. Nyden, James E. Brown, S M. Lomakin
The flammability properties of honeycomb composites, which are used in the interior cabin compartments of commercial aircraft, were examined. Analyses of the gases evolved during the thermal degradation of the components indicated that the phenol

Design of an Atomic Force Microscope with Interferometric Position Control

August 19, 1994
Author(s)
J Schneir, T Mcwaid, J Alexander, B Wilfley
Advances in the manufacture of integrated circuits, x?ray optics, magnetic read-write heads, optical data storage media, and razor blades require advances in ultraprecision metrology. Each of these industries is currently investigating the use of atomic

Applications of the NIST RoboCrane

August 18, 1994
Author(s)
Roger V. Bostelman, James S. Albus, Nicholas G. Dagalakis, Adam S. Jacoff, J Gross
The Robot Systems Division of the National Institute of Standards and Technology (NIST) has recently been experimenting with a variety of applications for the NIST ROBOCRANE. The ROBOCRANE design utilizes the basic idea of the Stewart Platform parallel

Analysis of Robotic Vehicle Steering and Controller Delay

August 17, 1994
Author(s)
Karl Murphy
Robotic vehicles are driving at highway speeds using computer vision and other methods to detect the vehicle¿s position on the roadway. Several factors affect system performance and stability. In this paper a simple vehicle and path following model is

Concepts of the NIST EXPRESS Server

August 1, 1994
Author(s)
Don E. Libes
The National Institute of Standards and Technology (NIST) has built numerous software toolkits and application for manipulating STEP and EXPRESS data. The NIST EXPRESS Server is a computational facility at NIST, which provides the ability to run these
