It will be remembered, that at the meeting of the British Association at Southampton in 1882, the late Sir W. Siemens proposed that the unit of power should be the watt, and that the watt, which was derived from the C.G.S. system of absolute units, should in future, among electricians, be the unit of power.
This admirable cable steamer of 5,000 tons register was built for Messrs. Siemens Brothers by Messrs. Mitchell & Co., at Newcastle. The designs were mainly inspired by Siemens himself; and after the Hooper, now the Silvertown, she was the second ship expressly built for cable purposes. All the latest improvements that electric science and naval engineering could suggest were in her united.
He was a man who took little or no leisure, and though he never appeared to over-exert himself, few men could have withstood the strain so long. Siemens was buried on Monday, November 26, in Kensal Green Cemetery.
Experiments with carbureted water gas gave the following results, with a consumption of 5 cubic feet per hour: For many years no advance was made upon these forms of burner, but when, ten years ago, it was recognized that anything which cools the flame reduces its value, while anything which increases its temperature raises its illuminating power, then a change took place in the forms of burner in use, and the regenerative burners, introduced by such men as Siemens, Grimston, and Bower, commenced what was really a revolution in gas lighting.
The use of superheated steam, however, still proved a drawback, and the Siemens engine has not been extensively used. On the other hand, the Siemens water-meter, which he introduced in 1851, has been very widely used, not only in this country, but abroad. It acts equally well under all variations of pressure, and with a constant or an intermittent supply.
Now, it is common to say, merely, in explanation of this luminosity, that the gas highly heated in combustion is self-incandescent. This explanation, however, has not been experimentally confirmed. Dr Werner Siemens was, therefore, led recently to investigate whether highly-heated pure gases really emit light.
The latter instruments were applied to the Sardinia, Malta, and Corfu cable. In 1859, he constructed an electric log; he discovered that a dielectric is heated by induction; he introduced the well known Siemens' mercury unit, and many improvements in the manufacture of resistance coils.
This firm, the pioneers of ship lighting by electricity, has already fitted out hundreds of vessels with electric lights. They also manufacture submarine and land telegraphs in vast quantities, having aided largely in enclosing the globe in a network of cables. All the Siemens brothers have shown much ability.
On July 23, 1859, Siemens was married at St. James's, Paddington, to Anne, the youngest daughter of Mr. Joseph Gordon, Writer to the Signet, Edinburgh, and brother to Mr. Lewis Gordon, Professor of Engineering in the University of Glasgow, He used to say that on March 19 of that year he took oath and allegiance to two ladies in one day to the Queen and his betrothed.
Before passing on to consideration of the petrol-driven type of engine, it is necessary to accord brief mention to the dirigible constructed in 1884 by Gaston and Albert Tissandier, who at Grenelle, France, achieved a directed flight in a wind of 8 miles an hour, obtaining their power for the propeller from 1 1/3 horse-power Siemens electric motor, which weighed 121 lbs. and took its current from a bichromate battery weighing 496 lbs.
