Aircraft Quality Casting Standards, Robert Katz, Robert Bolin , Depositor Jul 1942

Aircraft Quality Casting Standards, Robert Katz, Robert Bolin , Depositor

Robert Katz Publications

These standards are to be used in connection with the Handbook for Instructions for Aircraft Designers, 8th Edition …

In the radiography of aircraft castings, markings appearing on the film may be attributed to either the condition of the castings examined, or to some details of the radiographic process entirely unrelated to the quality of the castings, These latter patterns must be recognized and related to the radiographic process so that sound castings will not be unnecessarily rejected. Radiographs must be carefully compared with the surface irregularities of the casting they represent before an attempt is made to …

Fossils have also been obtained from a limestone formation in northwestern Montana and from four different areas in the Amsden formation in central and western Mont­ana.


Helena And Ennis Talc Deposits, Howard N. Anderson May 1942

Helena And Ennis Talc Deposits, Howard N. Anderson

Bachelors Theses and Reports, 1928 - 1970

The purpose of this report is to collect geologic data concerning two Montana talc occurrences at Helena and Ennis and to offer some explanation as to their origin. The two deposits cited are in somewhat similar lithologic settings and both possess the same mineralogical and structural features. Because of this similarity only the Helena deposit is covered in detail.

An Experimental Investigation Of The Age Hardening Of Nickel With Boron, Willard M. Boam May 1942

An Experimental Investigation Of The Age Hardening Of Nickel With Boron, Willard M. Boam

Bachelors Theses and Reports, 1928 - 1970

Since 1911, at which time, the age hardening phenomenon of duralumin was discovered by Film, much re­search has been carried on investigating the various alloy systems. The successful application of age hardening to the copper aluminum system (duralumin) has indicated the possibility of hardening practically all the metals in the same way.


An Investigation Of The Age-Hardening Of Copper With Nickel-Boron Compounds, Robert I. Moreen May 1942

An Investigation Of The Age-Hardening Of Copper With Nickel-Boron Compounds, Robert I. Moreen

Bachelors Theses and Reports, 1928 - 1970

Boron is an element whose metallurgical possibil­ities have never been fully investigated. The principal reason for this fact seems to lie in the difficulties encountered in preparing elemental boron and its various intermetallic compounds.


Porosity And Oil Absorption Properties Of Metal Compacts Of Copper - Tin - Graphite, Benjamin F. Mills May 1942

Porosity And Oil Absorption Properties Of Metal Compacts Of Copper - Tin - Graphite, Benjamin F. Mills

Bachelors Theses and Reports, 1928 - 1970

Powder metallurgy, the most recent innovation in met­allurgical process, is not a new art; although not until recently did it become a matter of general interest, this being due not only to the products formed but also to the possibilities of future developments. The manufacture and application of metal powders is now beginning to take a position as a recognized part of the science of metallurgy.

Bachelors Theses and Reports, 1928 - 1970

Since 1880, when Wolcott Gibbs made the suggestion that mercury could be used as a cathode in gravimetric electroanalysis, many articles have appeared in literature either criticizing the method or citing successful results which have been obtained by it.

A Study Of The Dissolution Of Pyrolusite In Sulphuric Acid, John J. Worsdell

Bachelors Theses and Reports, 1928 - 1970

With an eye to the future development of its re­sources, the large deposits of low-grade manganese ore within Montana's boundaries show great promise of developing an important industry. With the pre­sent war demands and the possibility of a future mar­ket it is essential that work expended to utilize this important mineral.

An Investigation Into The Recovery Of Indium From Fume Residue, Emery J. Turner May 1942

An Investigation Into The Recovery Of Indium From Fume Residue, Emery J. Turner

Bachelors Theses and Reports, 1928 - 1970

Several months were required to produce a single gram of indium. Consequently, the industrial history of the metal is extremely short. In view of the unique properties that indium has demonstrated in this short period, it is probable that indium is still in its early stage of development. However, the commer­cial applications of the metal are well established and indium is now produced on a commercial scale. It is obtainable as the metal or in solution for electroplat­ing.


Some Leaching Characteristics Of The Butte Rhodochrosite, W. L. Slosson May 1942

Some Leaching Characteristics Of The Butte Rhodochrosite, W. L. Slosson

Bachelors Theses and Reports, 1928 - 1970

With the increasing importance of manganese in the metallurgical fields of today and tomorrow, ex­tensive work along the lines of its successful ex­ploitation has been accomplished by many investiga­tors. Since tie current world situation has shut off most of our supply of high-grade manganese ores from foreign sources, the low-grade domestic deposits have entered the fields of investigation very rapidly.


The Effects Of Some Percentages Of Nickel On The Annealing Of Cartridge Brass, A. Edward Zezula May 1942

The Effects Of Some Percentages Of Nickel On The Annealing Of Cartridge Brass, A. Edward Zezula

Bachelors Theses and Reports, 1928 - 1970

The most important element in the alloying of steels, has also been used quite extensively as a third constituent in copper-zinc alloys. The chief characteristics of nickel which make it desirable as an alloying element are its toughness, high strength, and resistance to corrosion.


The Anodic Oxidation Of Vanadium In Phosphoric Acid Solution, Ben H. Alexander May 1942

The Anodic Oxidation Of Vanadium In Phosphoric Acid Solution, Ben H. Alexander

Bachelors Theses and Reports, 1928 - 1970

The purpose of this thesis was to analyze the possibility of recovering the vanadium in the phosphoric acid by anodic oxidation in an electrolytic cell.

The Velocity Of Falling Particles In A Liquid Medium, Elliott Coldwater May 1942

The Velocity Of Falling Particles In A Liquid Medium, Elliott Coldwater

Bachelors Theses and Reports, 1928 - 1970

The investigation was prompted by the fact that there seemed to be some discrepancy between the results published by Richards,and the empirical figures used in classification and in gravity concentration. Further, the work of Richards was restricted to quartz and galena whereas this study also includes pyrite and calcite.
