A Thesis Submitted To The Faculty Of Marquette University, Lester James Myers

Bachelors’ Theses

Since the commerce of a country or city determines its position in the world of finance to such a great extent, it is natural to investigate the conditions which govern the country's or city's demand for its share of this commerce, and see if the natural location, and still does not receive its share of the commerce of the country, there is a decided chance for the investigation and removal of the obstacles which are the cause of this condition.

The Design Of A Twelve Story Reinforced Concrete Warehouse, A. M. Fromherz

Bachelors’ Theses

In submitting this design I do so with the one point in view, namely, to endeavor to determine when reinforced concrete becomes impractical for design purposes.

To produce a maximum condition of loading on the lower floors I have taken up the design of a warehouse which is to carry a live and impact load of 400# per sq. ft., plus the dead load on each of the twelve floors. This condition of loading is not practical for design, but it will produce our desired conditions.

From the design it can be readily seen that the columns become excessive in …

The outer harbor project shall consist of a series of docks and wharves, which eventually will extend all along the lake front South of Wisconsin St. and as far south as the Illinois Steel Company's plant.

With the realization of the outer harbor complete, arises a problem of conveying and transferring the immense quantities of freight which shall be unloaded at this outer harbor, which problem shall eventually be answered by building a network of railway tracks on a section of the six-hundred …

A Thesis Presented To The President And The Faculty Of Marquette University For The Degree Of Bachelor Of Science In Civil Engineering And Bachelor Of Science In Electrical Engineering, Anthony B. Czachurski, Benjamin D. Ratke, Joseph G. Casey, William H. Stephan

Bachelors’ Theses

In the work covered by this thesis it is desired to examine an undeveloped water power for the purpose of producing electrical energy as a commercial comodity. Experience has taught that it is best to ascertain first where the product will find its market, and to follow up a satisfactory showing at that end by determining the power capacity of the source, the feasibility of harnessing the same, and the cost of accomplishing this. This program would be adopted in any commercial enterprise to insure a reliable conclusion, and will be followed as closely as possible in the work covered …

The Decreasing Of City Garbage And Sewage Sludge, O. Henry Babcock

Bachelors’ Theses

At the present time there seems to be no general solution of the problem of garbage and sewage sludge disposal, and the chances are that there never will be. The problem in each city is different so that no set rule can be given that will apply to every city. Therefore it is an original problem with each city, governed by cer­tain conditions existing there.

This formation has a thickness of several thousand feet and is composed of layers of dolomite, limestone, sandstone, shale and some chert. The ore bearing portion at least is much folded with minor faulting and high brecciation. The axis of the folds lie Northeast by Southwest with the faulting in the same direction. The ore being mined is found on the Southeast dip in a fairly definite …

Comparison Of Operating Expenses And Capital Expenditures Of Two Different Types Of Boiler Rooms Covering Extensions Expected During The Next Twenty Years, George Hewitt Boyer

Professional Degree Theses

"This thesis applies to a central power station located in a rapidly growing manufacturing city with a present population of 40,000. The station is connected by high voltage transmission lines with six hydro and steam generating stations located in other cities. These transmission lines are mainly for emergency purposes so that this report considers that the station here studied will carry its full load.

Cyaniding The Buckhorn Clay, Paul Richardson Cook

Professional Degree Theses

"The Buckhorn, Nevada, gold mine is peculiar in being a shallow kaolinized mass of material with basalt walls, having no direct connection with any of the usual gold bearing rocks, the average ore containing 16% water of hydratum. the cyaniding of this hydrant clayey material offered unusual difficulties compared with the usual gold quartz ore of Nevada. The ore body was thoroughly developed; then the mill was built according to the latest cyanide practice, with such changes as was thought the peculiar nature of this ore demanded. Upon starting the mill, the ore proved more difficulty to handle than had …

Construction And Maintenance Of Kansas City Boulevard Pavements, Ralph Robert Benedict

Professional Degree Theses

"In the first years of the history of the Park and Boulevard System of this city, road surfaces for boulevards received careful consideration for people were not satisfied with a good earth road well maintained. As the years have passed and the great changes have come in the methods of transportation, the evolution of pavements has had to keep pace with these changes"--page 1.

The Flotation Of A West Joplin, Mo. Slime, John Stone Hoffman, James Joseph Dowd

Bachelors Theses

"Owing to the high price of zinc and the success attending flotation in other districts, intense interest was aroused in the flotation of slimes of the South-West Missouri District. These slimes are the accumulation of the finer particles of the ore during the milling process and their metallic content is generally higher than that of the original ore. They have been disposed of, in the past, by sluicing them to the tailings ponds because no economical method of saving the zinc had been discovered. The object of our experiments was to economically extract from these slimes, by flotation, a product …

Leaching Experiments On An Arizona Copper Ore, Gunnard Edmund Johnson

Bachelors Theses

"The object of this thesis was to obtain a general knowledge of the problems to be solved in leaching a typical carbonate copper ore or oxidized capping of the New Cornelia Copper Co.'s ore. The experimental work previously performed far exceeds any that might be attempted in the short time allotted to this work, and the few results obtained indicate that the ore is particularly favorable for leaching"--Scope of Thesis, page 1.

The Effect Of Temperature Upon The Crystal Size And Physical Properties Of Iron And Steel, Earl Joesting Mcnely

An Investigation In Concrete, Don H. Morgan

Bachelors Theses

"It is the purpose of this investigation to determine the effect of blending a portland cement with a fine silica sand. A blended cement such as this has been used successfully and economically in several important works. The United States Reclamation Service and the Los Angeles Aqueduct commission have made use of such a blended cement in several important structures. This dilution, so to say, of the cement results is a decrease in cost without a loss of strength. In this investigation it has been assured that the cement retained on a #200 sieve is inert and may be replaced …

Method And Cost Of Rock Excavation, Inlet Swamp Drainage District, Lee County, Illinois, Arch W. Naylor

Professional Degree Theses

"The Inlet Swamp Drainage District, comprising 32000 acres of rich muck land, lies in Lee County Illinois, between the Chicago and Northwestern Railway, the Illinois Central Railway and the Chicago, Milwaukee and St. Paul Railway. The District is fifteen miles long and from one to five miles wide. The watershed has approximately five times the area of the swamp, and in early days, as much as one-half the thirty two thousand acres was under water for practically the entire year. It was not unusual in the Spring, for the swamp to be under from two to five feet of water. …

Land Drainage In Central Iowa, Ernst Lorenze Chamberlain

Professional Degree Theses

"The problems encountered in land drainage are comparatively simple when seen from an engineering point of view. Most problems do not require a fine scientific or mathematical analysis but are rather questions to be decided by good judgment or practical common sense. The most difficult problems encountered are financial, legal and political, therefore, in this paper considerable attention is paid to the Iowa drainage law, facts learned from practical drainage men and to the organization and operation of the different financing systems for drainage"--page 1.

An Investigation Of Blended Cements, Byron Lee Ashdown

Bachelors Theses

"It is generally accepted to be a fact that the coarser particles of a cement are practically inert, and that it is only the finest particles that possess the cementing qualities. Exactly what percentage of the whole is active, or possesses the cementing properties, is not known. Since but few experiments pertaining to such have been performed there is consequently little data to be found"--Introduction, page 3.

Flotation Applied To Silicate Sludge, Yaro Klepel, Greene Erskine

Bachelors Theses

"Within the past few years great success has been made of the flotation of sulfids, and to a certain extent of carbonates.

Since sulfids are easily recovered by flotation it seems practicable that silicates could be made to float by first sulfidizing them, and then subjecting them to ordinary flotation treatment.

This problem involves the treatment of a silicate sludge obtained from the Joplin district, the sludge will easily pass through a 250 mesh screen. At the present time this sludge is being sent to the tailings pond.

The experimental work of this thesis was done along the line of …

Pneumatic Ore Concentration, Robert Winters Johnson, Walter William Weissbach

Bachelors Theses

"The concentration of lead and zinc ores by means of air is practically an unexplored field, although the subject is by no means a new one. Considerable research work has been done and several methods, processes and machines have been developed, but little or nothing has been accomplished towards making air separation a success. the lack of success has been due mainly to two reasons:- (1) That very little has been known about the internal conduct of air currents, and (2) that nearly all methods and machines so far worked out have presupposed the fact that the ore to be …
