It did not fill my expectations, but I, by sheer chance, happened to notice a few bright specks on the end of the arc carbon that had been in the mixture. I placed one on the end of a lead pencil and drew it across a pane of glass. It cut the glass like a diamond. I repeated the experiment, and collected enough of the material to test its abrasive qualities. I mounted an iron disc in a lathe, and, oiling its surface,...
Page 98 - An iron bowl, such as plumbers use for holding their melted solder, was attached to one lead from a dynamo and filled with a mixture of clay and powdered coke ; the end of an arc light carbon attached to the other lead was inserted into the mixture. The percentage of coke was high enough to carry a current, and a good strong one was passed through the mixture between the lamp carbon and bowl until the clay in the center was melted and heated to a very high temperature. When cold, the mass was examined....

"In the observations described in this paper, and in fact in all the work that has been done in this field, there is not a more impressive example of the efficiency of graphite in lubrication than that presented in the curves of friction and temperature of water and graphite; for water serving merely as a vehicle and completely devoid of lubricating quality, the graphite is permitted to perform its work without...
Page 108 - Falls was at this time approaching completion. I went to Niagara Falls, looked over the situation, possibilities, and prices. On my return I convened a meeting of my board of directors and laid before them a scheme of moving to Niagara Falls and there building and equipping a plant for 1,000 horse power.

The next step was the transference of the graphite from the water medium to an oil medium, to form an improved lubricant called Oildag. Acheson felt that those two products would probably prove to be of more value to the world than any of those he had previously developed.
