Reaction chromato-mass spectrometry when studying cyclopropane compounds

May 1, 1983
Author(s)
Anzor Mikaia, Lyudmila Medvedkova, Vladimir G. Zaikin, Valentin Vdovin, A Kamisheva
A GC-MS method for structure elucidation of cyclopropane compounds is developed. The method includes the use of hydrogenolysis microreactor in the inlet system of a GC-MS and H2 or D2 as carrier and reagent gas.

Optical Properties of Small Metal Spheres: Surface Effects

April 25, 1983
Author(s)
David R. Penn, S Apell
It has been assumed that the optical properties of small spheres can be understood by means of a Drude dielectric function that incorporates a boundary scattering rate 1 / τ s=v F / R, where vF is the Fermi velocity and R is the sphere radius. An effective

Analysis of Electrical Fire Investigations in Ten Cities. Interim Report.

April 1, 1983
Author(s)
A Gomberg, J R. Hall
his report describes the results of an analysis of electrical fire cases by the Center for Fire Research, National Bureau of Standards for the Consumer Product Safety Commission. The report describes the 105 detailed electrical fire investigation reports

New Insights from Electron Spin Polarization Studies of Surfaces

April 1, 1983
Author(s)
Daniel T. Pierce, Robert Celotta
Examples of recent investigations in several laboratories, where measurement of effects due to electron spin polarization provided new insight into surface phenomena, will be reviewed. The results to be discussed include the use of spin dependent electron

Review of Compartment Fire Models.

April 1, 1983
Author(s)
Walter W. Jones
We have examined the concept of zone modeling as it has been applied to fire problems. The existing models which embody the zone concept are compared in order to ascertain the state-of-the-art in understanding of fire growth and fire spread processes. This

Computer Architecture for Small-Batch Manufacturing

March 2, 1983
Author(s)
Charles R. McLean, Mary Mitchell, Edward J. Barkmeyer Jr.
The advent of fully automated, integrated, small-batch manufacturing control system has been slowed by several problems: the systems are complex, their development is costly, and the technology is not yet mature. But even more of a hindrance has been the

A UHV-Gasket Removal Tool

March 1, 1983
Author(s)
B Waclawski
This note describes a safe, effective tool for removing copper gaskets from ultrahigh vacuum flanges. Use of the tool practically reduces to zero the chance of damaging the flange sealing surface, because all motion of the tool is away from the flange face
