This was in Eighteen Hundred Seventy, and Edison was then twenty-three years old. He studied out how stock-reporting could be bettered and invented a plan which he duly patented, and then laid his scheme before the Western Union managers.
Varley patented it on December 24, 1866; Siemens called attention to it on January 17, 1867; and Wheatstone exhibited it in action at the Royal Society on the above date. But it will be seen from our life of William Siemens that Soren Hjorth, a Danish inventor, had forestalled them.
It was through the instrumentality of this relative that the Duchess learned of an invention, perfected and very nearly patented by a Monegaskan savant, by means of which the home-life of the Mediterranean sardine might be studied at a depth of many fathoms in a cold white light of more than ball-room brilliancy.
Needless to say that the patented remedies most in request are those that profess a secret and unscientific origin.
Heath patented the process in 1845; and a quantity of cast-steel was actually prepared in this way, on the bed of a reverberatory furnace, by Sudre, in France, during the year 1860. But the furnace was destroyed in the act; and it remained for Siemens, with his regenerative furnace, to realise the object. In 1862 Mr.
The side of the wheel towards the camera may be black, by which means the result will be a dark instead of a light border. This process is also patented, and the remarks on the preceding subject will apply in this case. The plate is prepared and exposed as in the usual method of the Daguerreotype. A white back-ground is employed.
Sidney was to be a draughtsman of some kind; perhaps an artist, if all went well. Unhappily things went the reverse of well. In his anxiety to improve his business, Mr. Kirkwood invented a new kind of 'composition' for printers' use; he patented it, risked capital upon it, made in a short time some serious losses.
I don't wonder you don't want Andy to get even a peep at it." "Especially as I haven't it fully patented," went on the young inventor. He had met with many failures in his efforts to perfect this motor, which he intended to install on one of his airships. "If any one saw the finished parts now it wouldn't take them long to find out the secret of doing away with the noise."
Belcher, who did not love him well enough to betray me. And, thanks to the ministry of the best friends that God ever raised up to a man, I am here to-day to claim my rights." "These rights," said Mr. Balfour, "these rights which you hold in your patented inventions, for all these years used by the defendant, you say you have never assigned." "Never."
From the experience he had from this wheel he invented and patented Feb. 22, 1859, his improved Jonval turbine, which was very simply constructed and yielded a greater percentage of power than the French Jonval turbines. Hundreds of these improved wheels, which were put in operation between the years 1859 and 1868, are still in use. In 1870, Brightwell & Davis sold their mill to Scott & Davis.
