A circuit design to generate and maintain a constant magnetic flux

Creator:: Tuntawiroon, Chalermchai
Abstract:: A circuit designed to generate and maintain a constant magnetic flux is presented by using a sample-data control system, instead of a continuous control system. A Hall generator is used as the magnetic sensing element, and is operated with a pulse bias to allow a large output. The output of...

The theory and application of galvanovoltammetry. Design, construction and evaluation of a continuous liquid stream analyzer employing a galvanovoltammetric detector and low cost automatic digital concentration readout

Creator:: Kendall, Donald Ray
Abstract:: The theory and ways of applying a new electroanalytical detectior method were developed. The method, called galvanovoltammetry, consists of the measurement of current from the bipolar electrode of a three electrode cell which consists of a working electrode and a counter electrode, between which a constant current is applied, and...

An investigation of the removal of ozone by activated charcoal

Creator:: Liffick, Glenn Lonngren
Abstract:: The removal of ozone from an air stream by activated-cocoanut charcoal was investigated from the literature and experimentally. The experimental investigation showed that activated-cocoanut charcoal can be used to remove concentrations of ozone less than 1.0 ppm with high efficiencies. The mechanism of the ozone removal appeared to be a...

A study of the quantity and distribution of bark debris resulting from log rafting

Creator:: Williamson, Kenneth J.
Abstract:: A study was conducted to determine the quantity and distribution of bark debris resulting from log rafting. Three distinct problems were studied: (I) the quantity of bark dislodged from the logs while being placed in the rivers and during transport in log rafts; (2) the percentage of the bark that...

Heat and mass transfer rates associated with the drying of Southern pine and Douglas fir veneer in air and in steam at various temperatures and angles of impingement

Creator:: Laity, Walter William
Abstract:: Southern pine and Douglas fir veneer samples were dried in air under the following conditions: air temperatures were 350, 600, and 750°F; air velocities were 50, 100, and 150 feet per second, and angles of impingement of air against the veneer surfaces were 0°, 45°, and 90°. The resulting drying...

Low temperature deformation characteristics of high purity zirconium single crystals

Creator:: Goodrich, David George
Abstract:: High purity single crystals of zirconium were produced and mechanically strained in the temperature range from 4.2°K to 293°K. The crystals were produced by thermal treatment with a specially constructed electron beam zone refiner which provided the abrupt temperature gradient necessary for crystal growth. Specimens were electrolytically machined to have...

Numerical methods for variable permeability magnetostatic field problems

Creator:: Anderson, Lee Roy
Abstract:: Solutions to the variable permeability magnetostatic field problem are achieved in both rectangular and cylindrical coordinates for a wide variety of magnet geometries. The resulting difference equations are solved iteratively and a method is provided which substantially increases the rate of convergence for these type of problems. Magnetization curves for...

Henry Augustus Rowland and his electromagnetic researches

Creator:: Miller, John D. (John David)
Abstract:: This analysis concerns the life and scientific work of Henry Augustus Rowland (1848-1901), organizer and the first chairman of the physics department at The Johns Hopkins University in 1876. Special materials used in this research included three pieces of Rowland's experimental apparatus which are extant in the Smithsonian Institution Division...
