The Preparation, Acid Hydrolysis And Magnetic Transformation Of Iron Carbide , Waite Philip Fishel Jan 9863

The Preparation, Acid Hydrolysis And Magnetic Transformation Of Iron Carbide , Waite Philip Fishel

Retrospective Theses and Dissertations

In Part I, a new and simple method has been described for the separation of iron carbide from iron-carbon alloys;In Part II, it has been shown that the carbon evolved by acid hydrolysis of iron carbide, plus the free carbon formed, equals the total carbon present in the carbide. This proves that the carbon-containing products formed are either gas or volatile liquids. The reaction between hydrochloric acid and iron carbide produces about 12.5% of the total carbon as free carbon and the remaining 87.5% as volatile hydrocarbons;The gases evolved were found to be composed of 83 ...

A Comparative Study Of Measured And Computed Stresses In The Thirteenth Street Bridge Over Skunk River Near Ames, Iowa, Harry G. Neyenesch Jan 9133

A Comparative Study Of Measured And Computed Stresses In The Thirteenth Street Bridge Over Skunk River Near Ames, Iowa, Harry G. Neyenesch

Retrospective Theses and Dissertations

Last fall as school opened, Mr. Sigmund Eiken and the author, were presented with the opportunity of measuring the stresses in a highway bridge, about to be erected, near Ames Iowa. This structure is located just east of Ames, on Thirteenth Street extended, and spans the Skunk River at this point. [...] As previously stated this bridge is located near Ames Iowa, and is a 120-foot span, 20-foot roadway, through riveted steel highway bridge, with an 8-inch concrete floor on steel stringers. A view of the bridge is shown in Fig. 1 and elevation of the truss in Fig. 2. The ...
