An Automatic Recording Titrator, Gerald Ross Umbreit, J. S. Fritz Dec 1957

An Automatic Recording Titrator, Gerald Ross Umbreit, J. S. Fritz

Ames Laboratory ISC Technical Reports

An automatic recording titrator is described which is applicable to all types of potentiometric titrations. Particular attention has been paid to the maintenance of accurate potential recording of the entire titration curve as well as accurate recording of the volume of titrant used. As a result the instrument is well-suited for analytical research where the complete curve, rather than just the equivalence point of the titration is of interest.

An Investigation Of Compressive Testing Of Concrete, Gilbert R. Williamson Sep 1957

An Investigation Of Compressive Testing Of Concrete, Gilbert R. Williamson

Civil Engineering ETDs

The strength of most materials is affected by the rate of application of the load and concrete is no exception. However, the effect of a varying rate of loading on the compressive strength of concrete has not been too fully investigated. This effect is one of the problems covered in this paper. The first investigation along these lines was done in 1917 by Duff Abrams of the Structural Materials Research Laboratory, Lewis Institute, Chicago. In 1936, Paul G. Jones and F. E. Richart, working at the University of Illinois Engineering Experiment Station, reported the result of their experiments of the ...

Ten Rural Highway Base Stabilization Projects, James H. Havens, William B. Drake Aug 1957

Ten Rural Highway Base Stabilization Projects, James H. Havens, William B. Drake

Kentucky Transportation Center Research Report

During the last week o£ September, 1956, the Division of Rural Highways requested assistance from the Research Division in conducting a series of ten experimental base stabilization projects which were to be geared more-or-less to a practical rural roads development program in which existing soils and local granular materials might be most advantageously treated and stabilized to provide fairly low cost base courses and surfaces, adequate for light rural traffic. The idea of actually constructing a base and bituminous surface for this type of road would represent a refinement over the traditional traffic-bound base type of construction which usually serves ...

Effect Of Calcium Fluoride Additions On The Sintering Of Magnesium Oxide, F. Wayne Calderwood, Dave Wilder Jul 1957

Effect Of Calcium Fluoride Additions On The Sintering Of Magnesium Oxide, F. Wayne Calderwood, Dave Wilder

Ames Laboratory ISC Technical Reports

The effect of additions of calcium fluoride on the sintering of a refractory grade magnesium oxide fired under reducing conditions was studied. Specimens were formed at very low pressures to simulate compaction achieved in the jolt-pack technique, and at higher pressures commonly encountered in · powder-pressing of ware. Specimens were fired in an induction furnace and held for pre-determined periods at temperatures ranging from 1300°C. to 1900°C. Shrinkage, bulk density, and grain growth factor were determined and presented as a function of composition and temperature.


An Investigation Of High-Strength, Deformed Steel Bars For Concrete Reinforcement, Sidney A. Guralnick, George Winter Jul 1957

An Investigation Of High-Strength, Deformed Steel Bars For Concrete Reinforcement, Sidney A. Guralnick, George Winter

Center for Cold-Formed Steel Structures Library

INTRODUCTION High strength steel as reinforcement for concrete has received some serious attention by researchers and by the construction industries as long ago as the early 1900' s. Recent developments abroad, notably in Sweden, Germany and Austria, have caused renewed interest in the use of this material in concrete structures. The term "high-strength" is somewhat ambiguous since it usually has been employed to describe the type of steel used in cables and strands for prestressed concrete or suspension bridge structures. Such steels commonly have proof stresses of the order of 200,000 psi. However, in the case of ordinary reinforced ...

An Investigation Of The Response Of A Velocity Sensing Resonant Oscillator In An Inertially Operated Distance Meter, Howard F. Devaney Jun 1957

An Investigation Of The Response Of A Velocity Sensing Resonant Oscillator In An Inertially Operated Distance Meter, Howard F. Devaney

Electrical and Computer Engineering ETDs

It was the purpose of this study to investigate the response characteristics of a resonant mechanical oscillator utilized as a governor in conjunction with an inertial distance meter to sense velocity of a carrier. In order to initiate any desired event at a predetermined velocity of a vehicle (for example: fuel cut-off in a conventional liquid fuel rocket motor) it is often desirable to utilize a component requiring no external power for its operation. Such a component would be activated by inertial force and, by some means, integrate the force (or acceleration) with one respect to time and provide a ...


The Analysis Of Two-Dimensional Laminar Flow Utilizing A Doubly Refracting Liquid, John William Prados Jun 1957

The Analysis Of Two-Dimensional Laminar Flow Utilizing A Doubly Refracting Liquid, John William Prados

Doctoral Dissertations

The optical characteristic exhibited by certain liquids known as flow double refraction offers attractive features in the analysis of two-dimensional laminar flow situations, especially those in which measuring probs are undesirable. Such liquids become anisotropic to the passage of light when set in motion; and when they are viewed in polarized light while flowing through a transparent channel, visible interference patterns are observed. These patterns may be related to the magnitude and direction of the shearing stresses set up by two-dimensional laminar flow, and from suitable calibration under down flow conditions they may be used to determine the stress distribution ...
