The Solubility Of Zinc Ethyl Xanthate In Water, Thomas M. Mckenzie
The Solubility Of Zinc Ethyl Xanthate In Water, Thomas M. Mckenzie
Bachelors Theses and Reports, 1928 - 1970
A determination of the solubility of zinc ethyl xanthate was attempted by measuring the refractive index of a saturated solution of that salt. The small increment in refractive index effected by adding zinc ethyl xanthate to water in saturation quantities rendered measurements difficult and of dubious accuracy.
Hydrogen Overvoltage Of Cadmium Bismuth And Antimony Bismuth Alloys, Edwin W. Stevens
Hydrogen Overvoltage Of Cadmium Bismuth And Antimony Bismuth Alloys, Edwin W. Stevens
Bachelors Theses and Reports, 1928 - 1970
A method to measure hydrogen overvoltage was developed and checked with metals of known overvoltage. Alloys of bismuth and antimony and of bismuth and cadmium were prepared and their overvoltages determined.
The Electrodeposition Of Copper-Cobalt Alloys, Richard L. Dunn
The Electrodeposition Of Copper-Cobalt Alloys, Richard L. Dunn
Bachelors Theses and Reports, 1928 - 1970
An attempt was made to deposit a 50:50 copper-cobalt alloy from various sulfate electrolytes. No true 50:50 alloy was obtained but various mixtures of cobalt and copper rich crystals were deposited.
Fluorite Near Silver Bow, Montana, Charles V. Campbell
Fluorite Near Silver Bow, Montana, Charles V. Campbell
Bachelors Theses and Reports, 1928 - 1970
The wartime demand for fluorspar has caused renewed interest in fluorite deposits. Near Silver Bow, Montana, a deposit of massive, coarsely crystalline fluorspar, which has not been described in the literature, has attracted the attention of the United States Geological Survey.
The Incompatibility Of Certain Alcohol And Soap Frothers, John Thomas Doherty
The Incompatibility Of Certain Alcohol And Soap Frothers, John Thomas Doherty
Bachelors Theses and Reports, 1928 - 1970
The purpose of this thesis is to elucidate this phenomena of frother incompatibility, and to offer an explanation based upon several divergent lines of investigation. The research was limited to four common frothing agents, namely, pine oil, n-amyl alcohol, sodium oleate, and sodium lauryl sulphate (Dreft).
Methods Of Determining Porosity And Spatter Losses Of Arc Welds, Campbell W. F. Funk
Methods Of Determining Porosity And Spatter Losses Of Arc Welds, Campbell W. F. Funk
Bachelors Theses and Reports, 1928 - 1970
The original objective of this project was to determine the effect of varying current intensity and electrode coating composition upon the spatter losses and porosity of arc welds made by alternating current. This subject was suggested by the Welding Research Council of the Engineering Foundation, which is a clearing house for welding research in order to avoid duplication of work.
Age Hardening Of Copper Antimony Alloys, William R. Stern
Age Hardening Of Copper Antimony Alloys, William R. Stern
Bachelors Theses and Reports, 1928 - 1970
A large number of alloys of varying percentages of copper and antimony were prepared. These alloys were treated in various ways which might be expected to produce age hardening. The effect of cold working was studied in the range where the alloys were malleable.
Production Of Iron-Tin Compacts By Powder Metallurgy And A Synopsis Of Their Principle Properties, Matt C. Andrews
Production Of Iron-Tin Compacts By Powder Metallurgy And A Synopsis Of Their Principle Properties, Matt C. Andrews
Bachelors Theses and Reports, 1928 - 1970
This thesis is concerned primarily with the production of metal powder compacts of iron and tin. In producing these compacts, the effects of processing variables on some of the essential properties of the pellets made were investigated.
Hardness And Electrical Resistivity Of Copper-Iron Powder Metal Compacts, Fred A. Foyle Jr.
Hardness And Electrical Resistivity Of Copper-Iron Powder Metal Compacts, Fred A. Foyle Jr.
Bachelors Theses and Reports, 1928 - 1970
Although powder metallurgical methods have been used for years to fabricate tungsten and platinum, very little scientific data have been recorded until the beginning of this century. A large percentage of all commercial production at present is based upon past practice rather than upon scientific knowledge.
The Electrodeposition Of Iron-Manganese Alloys, Raymond D. Magorien
The Electrodeposition Of Iron-Manganese Alloys, Raymond D. Magorien
Bachelors Theses and Reports, 1928 - 1970
An electrodeposition of an iron-manganese alloy was made from the same conditions determined by previous research. Various addition agents were experimented with in an attempt to produce better conditions for electro-deposition. It was found advantageous to add small amounts of sodium lauryl sulfate and ammonium sulfite to the electrolyte.
An Isopach Map And Discussion Of The Marine Jurassic Of Western United Sates And Canada, John H. Ferry
An Isopach Map And Discussion Of The Marine Jurassic Of Western United Sates And Canada, John H. Ferry
Bachelors Theses and Reports, 1928 - 1970
Recent demands for petroleum to carry on the war effort have resulted in widespread prospecting in the northern Great Plains. Nearly all oil wells now drilled are of a depth to penetrate the marine Jurassic formations. It is known that these strata differ in thickness from place to place, but information of distribution, thickness, and lithology has not yet been compiled.
Electroplating Of Chromium Upon A Nickel Plated Magnesium Alloy, Harmel Dawson
Electroplating Of Chromium Upon A Nickel Plated Magnesium Alloy, Harmel Dawson
Bachelors Theses and Reports, 1928 - 1970
A nickel plating operation for magnesium alloys was investigated and proved successful in plating a small sample of a typical commercial magnesium alloy, Dowmetal J1.
