Pagina 362 - Having thus described the nature of my invention, and the manner of performing the same, I would have it understood that I do not confine myself to the...
Pagina 35 - Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is (d).
Pagina 259 - Now Know Ye, that in compliance with the said proviso, I, the said Adolphe Nicole, do hereby declare that the nature of my said Invention, and the manner in which the same is to be performed, are particularly described and ascertained in and by the following statement thereof, reference being had to the Drawing hereunto annexed, and to the figures and letters marked thereon (that is to say...
Pagina 368 - ... building, immediately below, another parallelogram of the same dimensions was placed. When a spark from an electrical machine was transmitted through the upper parallelogram, an induced current was developed in the lower one, sufficiently powerful to magnetize needles, although two floors intervened, and the conductors were separated to the distance of thirty feet. In this experiment no electricity passed through the floors from one conductor to the other ; the effect was entirely due to the...
Pagina 371 - ... the smaller induced currents may not be felt by the machine. It must be recollected that the inductive influence takes place at a distance through all bodies, conductors and nonconductors; and hence no coating that can be put upon the wire will prevent the formation of induced currents. I think it not improbable, since the earth has been made to act the part of the return conductor, that some means will be discovered for insulating the single wire beneath the surface of the earth; the difficulty...

Pagina 370 - Richman, of St. Petersburg, should be recollected, who was killed, by a flash from a small wire, which entered his house from an elevated pole, while he was experimenting on atmospheric electricity. The danger, however, which has been apprehended from the electricity leaving the wire and discharging itself into a person on the road, is, I think, very small ; electricity, of sufficient intensity to strike a person at the distance of eight or ten feet from the wire, would, in preference, be conducted...
Pagina 166 - ... appendages, for the purpose of sifting and depositing the fine earth upon the grain, and throwing off stones and such matter as would obstruct the young sprout in coming through the ground, substantially as described and illustrated herein. ROBERT M. JACKSON. No. 9299. — Improved Spark Arrester. Having thus described the nature of our invention, and the manner in which it is operated, what we claim as new, and desire to secure by letters patent, is the revolving screen, F, in combination with...
Pagina 367 - Powerful electrical currents are produced in the wires of the telegraph by every flash of lightning which takes place within many miles of the line, by the action of dynamic induction ; which differs from the action last described, in being the result of the influence of electricity in motion on the natural electricity of the conductor. The effect of this induction, which is the most fruitful source of disturbance, will be best illustrated by an account of some experiments of my own, presented to...
