Economic And Engineering Study For The Rehabilitation Of An Obsolete Factory Area, William E. O'Brien

Bachelors’ Theses

The first example of City Planning in America was the laying out of the National Capital by the French Engineer L’Enfant. The next attempt at grouping of buildings extends .back at least to the World's Fair in Chicago. Following this, contributions to¬ ward better and broader planning were made by an organized group of architects, engineers, and landscape architects. This was followed by studies of better housing facilities, the forming of the Outdoor Art Association and the American League for Civic Improvements, both of which were later merged into the American Civic Association.

Producer Gas Practice In The Steel Industry, Horace Wilfred Hodges Jan 1930

Producer Gas Practice In The Steel Industry, Horace Wilfred Hodges

Professional Degree Theses

"The sources of energy for the industries are: 1. Water power; 2. coal, lignite, peat and Wood; 3. Natural and Artificial Gas; 4. Oil; 5. The Sun;s Rays; 6. The tides. The latter two sources may be eliminated from immediate practical use, owing to their cost and limited application. Therefore, the burden for many years will rest upon Water power, coal, gas and oil. We may also eliminate water power from the source of energy of the steel industry, due to the Mill's geographical location. Hence, for the near future, the steel industry's soul rests upon the production of coal, …

The Effect Of Occluded Air In Dry-Press Mixes, William Raymond Powell Jan 1930

The Effect Of Occluded Air In Dry-Press Mixes, William Raymond Powell

Bachelors Theses

"The effect of occluded air in clay mixes has recently become a subject of considerable importance especially since some of the defects occuring sic in dry-press ware, such as cracks and soft or granulated centers, have been either partially or wholly attributed to occluded air. According to this theory, the defects are due to the entrapping of air among the clay grains before compression, which, when the pressure is released, has a tendency to expand and cause a rupture in the bond. Also granulated centers have been explained by the fact that the entrapped air may act as a cushion, …


The Testing Of Steel For Wear By Abrasives, Thomas Evan Eagan Jan 1930

The Testing Of Steel For Wear By Abrasives, Thomas Evan Eagan

Professional Degree Theses

"The tests herein reported were conducted with the idea of finding a steel which would give improved wear as roll shells in the comminution of ores...Not only must the wear be considered, but also the physical properties. It is desirable to have a steel of such Tensile and impact values that no failure by breakage would occur until the shell was worn very thin. The ideal condition being to wear the shell down to zero thickness, but such cannot be accomplished"--Introduction, page 2.

The Effect Of Various Methods Of Grinding On The Physical Properties Of Unfired Dry Press Brick, Edwin Theodore Harvey Jan 1930

The Effect Of Various Methods Of Grinding On The Physical Properties Of Unfired Dry Press Brick, Edwin Theodore Harvey

Bachelors Theses

"In the manufacture of dry press brick, the final grinding of the clay is usually done in a dry pan. This is especially true of fire brick made by the dry press method. It is logical to assume that different types of grinding machines will impart different characteristics to the ground clay mix, as regards the grain size variation and the shape of the grains, which in turn will have an effect on the properties of the brick. The purpose of this investigation was to determine what effect different types of grinding methods have on the physical properties of unfired …
