Water And Water Vapor Barriers For Structural Plywood : Ii. Core Void Fillers For Structural Plywood., James Van Dyck Fear
Electronic Theses and Dissertations
This thesis presents the results of an investigation conducted to improve the weather resistance of plywood assemblies used in prefabricated housing manufacture. Specifically, this work involved water sealers for edge joints (called edge sealers), the prevention of surface transfer of water vapor through plywood (called vapor barriers), and fillers for structural defects in the wood (called core void fillers). Two edge sealers for plywood were developed that were considered successful in resisting water permeation. One was a quick drying paint formulated by the addition of 30 per cent leaded zinc oxide to 70 per cent Arco primer paint No. 156. …
Geology And Mines Of The Upper Blackfoot Valley, Montana, Thomas K. Shea
Geology And Mines Of The Upper Blackfoot Valley, Montana, Thomas K. Shea
Bachelors Theses and Reports, 1928 - 1970
The purchase and continued operation of the Mike Horse mine in the Heddleston district, by the American Smelting and Refining Company, gives the Blackfoot Valley a renewed promise of a prosperous future in its role as a mining district. In the past, large amounts of placer gold were recovered from the gulches of the area, however, because of the transportation facilities, only the upper portions of a few lodes were exploited by the early miners.
Rugose Corals Of The Madison Group, William R. Paine
Rugose Corals Of The Madison Group, William R. Paine
Bachelors Theses and Reports, 1928 - 1970
One of the best types of index fossils, and one which occurs most plentifully in the Madison group of formations in Montana, and yet, one which has been little studied, is the group of rugose, or cup, corals. Perhaps this group of fossils has not been studied in detail because their distinguishing characteristics are mainly internal, and laboratory preparation in the form of thin section or polished surfaces is necessary to bring out these characteristics.
Kibbey Sandstone In Montana, Glen Shean
Kibbey Sandstone In Montana, Glen Shean
Bachelors Theses and Reports, 1928 - 1970
Much attention has recently been given, by geologists, to prolific water bearing horizon and a potential oil horizon, known as the Kibbey sandstone, which lies deeply buried under much of central Montana. In some localities the sandstone is dry, and its identification in cuttings from deep wells has in many cases proved difficult.

Spot Welding Low Carbon Steel, Leonardo Gutierrez
Spot Welding Low Carbon Steel, Leonardo Gutierrez
Electrical and Computer Engineering ETDs
This investigation of spot welding on low carbon steel was undertaken to study the quality of welds under different welding conditions. Low carbon steel is one of the most readily weldable materials of all metals and alloys used in resistance welding processes. Its metallurgical structure is such that fusion between separate pieces may be accomplished in a broad range of temperatures, so that precise control of welding conditions is not necessary for producing a spot weld. Because of this ease in securing a weld, more and more of the many low carbon steel products are being spot welded. This makes …

The great diversity on mineral wealth in Idaho establishes it as one of the principle mining states in the union. Mining first began in the state with the discovery of placer gold in the Pierce City district in 1861, and since that date has become one of the leading industries of the state.
Upper Cretaceous Sediment In Montana, Frank J. Frankovich
Upper Cretaceous Sediment In Montana, Frank J. Frankovich
Bachelors Theses and Reports, 1928 - 1970
Cretaceous sediments in Montana record events during a period of unusual geologic interest. After a long period of extensive submergence of the area during Jurassic time, came a period of varying continental and marine deposition with consequent variations in the types of sediments laid down. A study of these variations, their extent, and their cause has been the primary object of this thesis.
Occurrence Of Native Copper Near Jefferson City, Montana, Terence G. Kirkland
Occurrence Of Native Copper Near Jefferson City, Montana, Terence G. Kirkland
Bachelors Theses and Reports, 1928 - 1970
Sometime prior to 1870, a group of prospectors made what was believed to be a "rich strike' on one of the tributaries of Prickly Pear Creek in Jefferson County, Montana. Instead of striking it rich, they had uncovered a native copper deposit, worthless to them because of its limited extent and remote location, but now of much interest to the geologist, and to the mining engineer because of its possible commercial value.
Electro-Deposition Of Iron From A Chloride Bath, Charles W. Noon
Electro-Deposition Of Iron From A Chloride Bath, Charles W. Noon
Bachelors Theses and Reports, 1928 - 1970
Iron was electro-deposited from a ferrous chloride bath. Studies were made of deposits formed when current density was varied, and finally when both current density and temperature were changed. An attempt was made to lay the ground work for a long range study of the chloride bath, and to determine the most simple conditions possible for obtaining a smooth, even, and thick deposit.

The Problem Of The Tensleep Sandstone, George D. Mccarthy
The Problem Of The Tensleep Sandstone, George D. Mccarthy
Bachelors Theses and Reports, 1928 - 1970
Sandstone is probably one of the most important groups of rocks in existence today. The economic importance of so insignificant a thing as a mass of sand grains grows with the true reality of the situation. By increasing our knowledge of grains of sand, or particles of sandstone in all their ramifications, it would undoubtedly reflect upon our everyday life by increasing commercial possibilities of an undeveloped natural resource of Montana.
