Page 753 - City, chairman of the committee on war memorial to American engineers, make the following declaration: In June, 1927, I went to Louvain as the delegate of the American Societies of Civil, Mining and Metallurgical, Mechanical, and Electrical Engineers, Engineering Foundation and Engineering Societies Library, to the celebration of the five hundredth anniversary of the University of Louvain.
Page 572 - Committee shall assume charge of the completed test welds and have them tested by the authorized representative in accordance with these specifications. (e) The authorized representative shall render to the Welding Committee a complete, detailed report of each test of an electrode.

The problem that arose was to devise means whereby the natural self-compensatory action of the arc could be so greatly accentuated as to preclude, within wide limits, the occurrence of marked arc abnormalities. There was ultimately evolved, by experiment, such a relation between- the fusing energy of the arc and the feeding rate of the welding strip as to give the desired arc length under normal conditions; and tendencies toward abnormalities in arc conditions, no...

Data for the pounds of metal deposited per hour are gradually becoming quite definite. The pounds of metal per foot of weld required to be deposited can be readily calculated from the drawings or specifications. With the further available knowledge of the average waste in electrode ends and from other causes, the required...

It did so, later gaining great profits from the connection and giving Frick a check for $50,000, a large part of which "he promptly invested in more lands and more ovens." In 1878, he sold an interest in the business to EM Ferguson, a Pittsburgh capitalist, which gave Frick additional capital to expand his holdings. When the depression had drawn to an end, the new firm...
