The Response Of Vibration Mounts Subjected To Biharmonic Vibration, Paul H. Adams

Mechanical Engineering ETDs

Existing specifications used in vibration testing are based on envelopes of many points of fixed frequency and vibration amplitude measured at specific points in aircraft. In addition these specifications are to some extent written to be compatible with the two common types of vibration test machines, the reaction or constant-displacement type and the electromagnetic or constant-acceleration type. Thus the "envelope" of the measured vibration amplitudes is drawn in such a manner as to have a constant displacement from 3 to 60 cycles per second, the range of the reaction type of vibration test machine, and a constant acceleration from 60 …

Observations Of The Manufacture And Placement Of Prefabricated Bridge Sections And Precast Concrete Riprap, Dave H. Sawyer

Kentucky Transportation Center Research Report

The design and equipment necessary in precast concrete operations has progressed in recent years to such an extent that the resulting products are now being used satisfactorily in many types of construction. This report covers two precast concrete products which the Department of Highways authorized in contracts let in 1954 and 1955. These items however, are not the first precast concrete products to be used by the Department. Two concrete bridges are known to have been precast and placed in Scott and Graves County sometime ago. Precast concrete cribbing has also been used for quite some time.

Bachelors Theses and Reports, 1928 - 1970

Located between the 100th and the 110th longitude east of Greenwich, between the 8th and 24th latitude north, Indochina is a peninsula known as "the balcony of Southeast Asia". It's three states Laos, Cambodia and Vietnam occupy an area as large as 770,000 square kilometers.

Observations Of Stabilized Turf Shoulders, Ellis G. Williams

Kentucky Transportation Center Research Report

The improvement of highway shoulders, from the standpoint of appearance and practical value, has been and is at present of considerable interest to all highway departments. A great deal of effort has been expended in the past to develop grass combinations which not only will prevent natural erosion of the surface materials but also impart a pleasing appearance to shoulders and slopes. Attempts to include factors of practical value, such as safe support of traffic loads, have greatly magnified the problem. Numerous types of paved shoulders have been introduced which are quite satisfactory with respect to load bearing but are …

Field Manual Fm 30-16, Technical Intelligence, 26 August 1955, Robert Bolin , Depositor

United States Department of Defense Military Intelligence

This manual outlines responsibilities for technical intelligence at all levels in the Army from the top level to units in the field. It discusses technical intelligence training, processing, and operations.

The modern US Army vision of the technical intelligence developed during World War II. The importance of studying foreign military equipment had become apparent and procedures for collecting and evaluating of equipment had been developed. Technical Intelligence procedures and organizations were refined during the cold war and Korean War. Period.

This manual represents a mature picture of Army technical intelligence as it was in the mid-1959s from the viewpoint of …

A Proposal For Two Computers Dealing With The Convolution Integral, Charles S. Williams Jr.

Electrical and Computer Engineering ETDs

The integral f(x) = g(x-y)h(Y)dy is known as a convolution integral. The first computer described herein will determine the function f when the functions g and h are known. The second computer will determine the function h when f and g are known; in using the second computer to find h, then the first computer is used for auxiliary computations.

Correlation Of Crystal Growth Rates In Supersaturated Solutions, Josef Frank Palme

Theses

This investigation has shown that crystals of copper sulfate and magnesium sulfate when grown in supersaturated solutions exhibit a growth rate according to the following equation:

R_L = 5.0 (ΔCD_m)^1/ρU V_s^.292

where, R_L, is the growth rate in Microns/min, is the change in concentration, D_m, the diffusivity coefficient, , density of solution, U, viscosity and V_s, solution velocity past the crystal.

The equation shown demonstrates that a mass transfer process is taking place from the solution to the crystal surface, and that within the velocity range studied, there …

The Recovery Of Krypton From Dilute Gas Mixtures By Elution Techniques, David Graham Brown

Theses

An analytical method has been empirically developed for the analysis of dilute inorganio inert gas mixtures.

The method is based on a combined sorption-elution technique which makes possible the resolving of complex inert gas mixtures into their constituents.

Particularly the recovery of krypton from dilute gas mixtures was accomplished. Recovery efficiencies were as high as ninety-eight percent, while the average krypton purity was better than ninety-nine percent.

Heat Transfer Coefficients For Condensing Vapors On A Horizontal Tube, Maurice Edward Brown, Rodwin Edwin Gulick

Theses

Film coefficients of heat transfer for vapors condensing on a smooth horizontal tube have been experimentally determined by many investigators. The so-called Thermocouple Method and the Wilson Method, have been used and generally accepted as the two methods for determining these film coefficients. A number of different organic vapors have been studied on various condensing surfaces. Nusselt has also developed a theoretical equation,

hN = 0.725 4√k_f³ρf²λg/D_oμfΔtcf

for evaluating the film coefficients of vapors condensing on hori?zontal tubes.

The earlier investigators have shown that theoretical values, hN do not check with experimentally determined …

The Analogy Between Heat And Mass Transfer In Packed Beds, Jasper Joseph Correnti

Theses

An operation which recurs in many branches of chemical engineering is that in which a fluid - gas or liquid - is passed through a bed of granular solids for the purpose of removing from, or adding something to the fluid (or both). In the oil and sugar industries, oils or syrups are passed through beds of adsorbents to remove impurities causing color and other undesireable effects. In the recovery of volatile solvents, air charged with solvent vapor is passed over solid adsorbents. In leaching, liquids are passed through beds of solids to remove some constituent of the solids. In …

The Effect Of Reduced Pressure On Variables In Distillation, Joseph Peter Cummins

Theses

To determine the effects of reduced pressure on pressure drop and holdup in distillations seven different liquids were distilled at varying rates at atmospheric pressure and under vacuum at pressures down to 50 mm Hg, using protruded stainless steel packing. Pressure drop and holdup were found to vary exponentially with masste at each pressure. At constant mass rate pressure drop was higher for decreased head pressure. Use of material of higher molecular weight led to lower pressure drop at same rate and pressure. Greatest effect of pressure on pressure drop was observed below 300 mm Hg. Liquid holdup was not …
