...rigged on the ground a large plate of metal, which was in effect a section of the earth's surface. When a thundercloud hung over his plate and lightning blazed, he found by means of extremely delicate instruments that the electrical potential of the plate changed. This was the electrical image of what happened in the cloud, one surface (usually the upper) was positively charged, the other negatively. When discharge occurred...
Alfred Moritz, another son, took up the industrial side, preparing himself by a thorough course in law. After his many corporations were thoroughly organized, for he early diffused his energies into metal making, coal mining and gas producing, he stood for parliament and won his seat. For most English gentlemen, politics are a duty. For Sir Alfred (he was created baronet in 1910), politics have been a duty and a tool. They gave influence to his affluence. He was one of Lloyd George's Liberals; became First Commissioner of Works, then Minister of Health in Lloyd George...
Seventeen of the canvases relate the visual majesty of 17 Toledo industries. In them rude men ladle out molten metal, neat girls direct bottle-filling machinery, smoke stacks smoke, vast iron wheels whir, newspapers flutter on the city, crowds walk in the rain before the shops, fantastic masses of machinery move. Two additional canvases show Toledo of today?neat, smoking, moving; Toledo of the future?a high, angled sky line rivaling that of Manhattan. The represented industries...
Electric Battery. An electric battery is a collection of electrolytic cells. The action of such cells depends upon the fact that different metals and their salts have different electric potentialities. When pieces of different metals or of a metal and its salt are touched together, there is a momentary passage of electricity between them. When the pieces are in a suitable electrolytic solution the current is continuous...
Some deposits which are apparently rich and deep prove to be only a thin layer of profitable ore over worthless rock. Electrical instruments are being devised to register not only the presence of metals, but the extent of the ore pocket, and so prevent wasted efforts. Metals have a decided influence upon delicate electrical mechanism, and the various effects of each metal give a key to the nature of the concealed deposit...
