Siemens took a great interest in this very original machine, and also devised a form applicable to the measurement of heights. Although he laid the subject aside for some years, he ultimately took it up again, in hopes of producing a practical apparatus which would be of immediate service in the cable expeditions of the s.s. Faraday.
It is, therefore, important to test lightning conductors from time to time, and the magneto-electric tester of Siemens, which we illustrate in figures 98 and 99, is very serviceable for the purpose, and requires no battery. The apparatus consists of a magneto-electric machine AT, which generates the testing current by turning a handle, and a Wheatstone bridge.
An electric tramway, six miles in length, had just been completed, connecting Portrush with Bush Mills, in the north of Ireland, in the installation of which the lecturer was aided by Mr. Traill, as engineer of the company by Mr. Alexander Siemens, and by Dr. E. Hopkinson, representing his firm.
To the ordinary observer, Siemens did not betray any signs of the untiring energy that possessed him. His countenance was usually serene and tranquil, as that of a thinker rather than a man of action; his demeanour was cool and collected; his words few and well-chosen. In his manner, as well as in his works, there was no useless waste of power.
Siemens Elektromotory's 3000 employees export $130 million worth of electrical engines annually. None of this would have been possible without Germany's vote of confidence and overwhelming economic presence in the Czech Republic. The deteriorating fortunes of the Czech economy are, indeed, intimately linked to the economic stagnation of its northern neighbor, as many an economist bemoan.
The first of such lines was, however, laid as long ago as 1848, by Werner Siemens, who, in the autumn of that year, deposited a subterranean cable between Berlin and Frankfort-on-the-Main. Next year a second cable was laid from the Capital to Cologne, Aix-la-Chapelle, and Verviers. In 1847 the subject of our memoir had, along with Mr.
This method, proposed as long ago as 1860 by Siemens, would offer considerable advantages.
In 1875, 1876 and 1877, he investigated the action of light on crystalline selenium, and in 1878 he studied the action of the telephone. The recent work of Dr. Siemens has been to improve the pneumatic railway, railway signalling, electric lamps, dynamos, electro-plating and electric railways.
Sir William Siemens was among the first to make an electric furnace heated by the arc, which fused and vapourised metallic ores, so that the metal could be extracted from them.
Siemens, and other gentlemen eminent in the specialty of telegraphy, one other unexpected compliment may be mentioned. The Professor was presented to the accomplished General Director of the Posts of the North German Bund, Privy Councillor von Phillipsborn, in whose department the telegraph had been comprised before Prussia became so great and the centre of a powerful confederation.
