The Manufacture Of Cement In The State Of California, William Alonzo Mccanless

Professional Degree Theses

"In studying the subject of cementitious materials, from a structural standpoint, we find as we retrace our progress, that concrete as evolved, has always had the commanding position of superiority as a structural material, it now enjoys in all stages of man's civilization"--page 1.

The Manufacture Of Airtight Leather Gaskets, W. Kedzie Teller

Professional Degree Theses

"Wherever gaskets are used in conjunction with any type of mechanism operated by compressed air, of course, it is essential that the gaskets be air tight. Whereas it is possible to use rubberized fabric for this purpose with a degree of satisfaction, treated leather has certain advantages which make its use preferable. Leather is readily available and can be cut and molded into various shapes with less difficulty than is encountered in fabricating similar designs from reinforced rubber. Then, too, leather withstands wear much better than rubberized fabric. The problem then arises to treat leather to make it airtight, for …

Preparation And Use Of Volcanic Ash In Concrete, Abner Decker Hahn

Professional Degree Theses

"During recent years, Kansas has produced over 90% of the volcanic ash produced in the United States. Other important areas of volcanic ash are to be found in California, Montana and Idaho. Extensive development of the latter named deposits awaits more advantageous markets than are now present"--Origin of Volcanic Ash, page 2-3.

Electrolytic Board For The Determination Of Lead, And Some Comments On The Procedure For Lead In Low-Grade Tailings Of The Southeast Missouri Lead District, O. W. Holmes

Professional Degree Theses

"Recent improvements in the practice of milling lead ores of the Southeast Missouri Lead Mining District has resulted in the production of low-grade mill tailings. The tenor of the lead in the tailings is often between 0.05 and 0.25 per cent. In view of the fact that large tonnages are handled daily and that further improvements are under way, it is imperative that the lead content of these tailings be accurately determined.

For this purpose an electrolytic board, which speeds up the electrolytic determination of lead in low-grade mill tailings, has been devised at the Mississippi Valley Experiment Station of …

The Coarse Crushing Plant Of The Desloge Consolidated Lead Company, Horace Reynolds Stahl, Robert Gibson O'Meara

Professional Degree Theses

"The Desloge consolidated Lead Company is located at Desloge, Missouri, in the disseminated lead district of St. Francois County. The crushing plant was built during 1925 to replace crushing installations at three mines. The plant was designed to deliver 2,000 tons of 7 to 9 mm. feed per day to the concentrating plant. Operating conditions have since improved so that the present tonnage is about 2,200 toms of 6.5 mm. feed per day, operating 16 hours. The essential mineral is galena, more or less finely disseminated in a dolomitic gangue. The ore is comparatively soft and easily crushed"--Introduction, page 1.

Florida Kaolin As The Chief Clay Ingredient For A Sanitary Ware Casting Body, Hugo Logan Harrod

Bachelors Theses

"The purpose of this investigation was to utilize a large percentage of Florida Plastic Kaolin in a new sanitary ware casting body. Such a body, when worked out to be satisfactory, could be produced at a lower cost than those bodies being used in American plants at present. This particular plastic kaolin is available in large quantities in the southeastern portion of the United States. It is the intention of this work to substitute this American clay for the more costly imported English China Clay now being used in sanitary ware casting bodies"--Introduction, Purpose of the Investigation, page 1.

A Study Of Chrome And Diaspore Mixes, Harlow Guy Jones

Bachelors Theses

"The high refractoriness of both chrome and diaspore make them very valuable to the refractory industry. Chrome ore has been experimented with since 1879 and used in brick form since 1886. Diaspore on the other hand, has just recently been recognized as a refractory After going through all the available literature on the subject I have been unable to find any mention of any work carried on in which mixtures of chrome and diaspore were used"--page 1.

Beneficiation Of Manganese Ores, Michael V. Healey

Masters Theses

"The purpose of this investigation is to study the means of beneficiating domestic manganese ores in order that a marketable product may be made. Within the limits of the paper the term "Manganese ores" is applied to those ores mined primarily for their manganese content, to the exclusion of manganiferous iron and silver ores"--Object, page 1.

A Study Of Crime And Criminal Statistics Of Phelps County, State Of Missouri, For The Period 1899-1929, Walter Llyn Bradford

Masters Theses

"It is only within very recent years that the study of Human Society has been undertaken in a really scientific manner. It is true that the social problems have been studied and ideas suggested and discussed for their solution since the very beginning of social organization, for nowhere has there been found a state of society so perfect that all members are completely satisfied with their well-being under it...The study of crime is a part of the science of sociology and must be made according to the same methods as apply to all other kinds of social phenomena"--Introduction, page 1-3.

Elutriation Of Flotation Products, Guenther Walter Frotscher

Masters Theses

"Since the first application of the flotation process in ore dressing practice, engineers have been busy solving the most delicate relations of metal distribution in the minerals to be treated...The desire for more information was the reason for research concerning the mineral distribution in fine flotation material with particular attention to the development of a suitable laboratory method of hydraulic classification or, as it is especially called, elutriation"--Introduction, page 1-4.

A Study Of Ball Mills, Robert Lee Kidd

Masters Theses

"The study of the ball mill is very complicated, due to the varying conditions existing in the mill. Some of these conditions are: Size of grinding media, size of feed, moisture content, and speed with its effect on the paths of the grinding media. A brief history of fine grinding will first be outlines, after which some of the theories of ball milling will be stated. Then the paths of the grinding media will be given some attention, and a new point of view about the trajectory will be brought out"--Introduction, page 2.

The Concept Of Social Determinism As A Motivating Influence In Some Modern Tragedy, Arthur Lenox Bradford

Masters Theses

"The term, "social determinism", is a rather unfortunate designation for the absolute conditioning of human character by the aggregate of biologic and social influences...The central idea of this positivistic interpretation is that man, along with all other organic things, is the product of hereditary accidence and environmental contacts, that his psychic and physical constitutions (if there be such differentiation) are fashioned to the minutest detail by circumstance, and that his thoughts and the chemic impulses of his nature appear precisely according to his character which he has no hand in making"--Introduction, page 2-3.

The Change In The Order Of Catalytic Action Of Lithium Chloride, Sodium Chloride, Magnesium Chloride, And Calcium Chloride In The Ketonic Splitting Of Ethyl Acetoacetate, Richard Dwight Duff

Masters Theses

"The catalytic action of neutral salts on many reactions has been investigated under various conditions, and a large number of explanations have been put forward. In this work the catalytic action of normal solutions of lithium chloride, sodium chloride, magnesium chloride, and calcium chloride in the presence of .1 N. hydrochloric acid on the ketonic splitting of ethyl acetoacetate has been investigated at several temperatures between 80⁰C. and 95⁰C. An attempt has been made to explain the results obtained"--Introduction, page 1.

Reaction Of Metallic Iron And Copper Sulphate In The Flotation Of Sphalerite, Charles Wilson Ambler

Masters Theses

"Copper sulphate is a common flotation reagent for blende ores. Metallic iron is also present in the mill circuit and a reaction between the iron and the salt would be in accord with well known chemistry. The abundance of metallic iron in a flotation feed may be noted by the examination of any feed. It originates, first of all, in the mine, then the coarse crushing machines contribute their share, and finally the fine grinding medium is a large contributor. If the grinding is with cast iron balls in amount of metallics is greater than when steel is used. In …

A Study Of The Basal Cherokee In The Rolla Area, Thomas Daniel Murphy

Masters Theses

"The occurrence of outliers of Pennsylvanian age, probably Cherokee, in and about Rolla has long been known. The Bureau of Geology and Mines and the Department of Geology of the School of Mines at Rolla have been greatly interested in the many stratigraphic problems presents. The writer has, therefore, undertaken field and laboratory studies of certain of these problems"--Introduction, page [1].

A Study Of The Determination Of Fluorine And Other Constituents In Fluorspar, Robert Knowlton Grantham

Masters Theses

"A method for the determination of certain constituents in fluorspar has been studied. Fluorspar can be complete decomposed by fuming with perchloric acid. Agitation and boiling is essential to a rapid and quantitative decomposition. Lead, ferric oxide, titanium oxide, aluminum oxide and total calcium have been quantitatively determined in the solution obtained by the perchloric acid method of decomposition. Silica cannot be determined quantitatively by the use of perchloric acid alone. Preferential solution of calcium carbonate by means of very dilute perchloric acid cannot be used as a method for determining calcium in carbonates in the presence of calcium fluoride"--Summary, …
