Pagina 101 - Son of his love ; in whom we have our redemption, the forgiveness of our sins: who is the image of the invisible God, the firstborn of all creation; for in him were all things created, in the heavens and upon the earth, things visible and things invisible, whether thrones or dominions or principalities or powers; all things have been created through him, and unto him; and he is before all things, and in him all things consist.
Pagina 58 - ... of the age, although it is not very well known, because only a few are required, and these are only to be seen abroad, if FIG. 23. we except those now being exhibited at the Crystal Palace, Sydenham. A general view of the instrument is given in Fig. 23, and the leading parts are detailed in Fig. 24. The principle of its action is just the reverse of the mirror galvanometer. In that instrument a tiny magnet moved within a fixed coil of wire ; in the siphon recorder a light coil of wire moves between...
Pagina 18 - Seebeck, that when two different metals are soldered together so as to form a closed ring or circuit, as at A in Fig 6, and one of the junctions is heated more than the other, an electric current is set up in the circuit. With one pair of junctions a very feeble current is produced, just as a single voltaic element gives a feeble current, but by combining a number of pairs in the fashion of B, Fig.
Pagina 8 - All things constructed as above, and the minute previously fixed, I begin the conversation with my distant friend in this manner. Having set the electrical machine a-going as in ordinary experiments, suppose I am to pronounce the word Sir; with a piece of glass or any other electric per se, I strike the wire S...
Pagina 30 - The magnetisation of a bar of steel or iron, according to this theory, consists in establishing within the metal by induction a series of electrical currents, all revolving in the same direction at right angles to the axis or length of the bar.
Pagina 3 - Hence we have the law that like kinds of electricity repel each other, and unlike kinds attract.
Pagina 11 - ... the supply of heat. No matter how long the connecting wire is, the current will flow through it, provided it is entire, and hence it is that we have telegraph lines two or three thousand miles long. The water in this combination supplies the oxygen to burn the zinc, and sulphuric acid is merely added to reduce the resistance of the water to the passage of the electricity through it, for the current starts from the zinc plate where the chemical action takes place, and flows to the copper plate...
Pagina 57 - The details of this needle are shown in the lower figure, where cc are sectionsthrough the coil, M is the magnet-needle, carrying in front of it a small mirror. This needle is enclosed in a small chamber, glazed by a lens G, and inserted in the hollow of the coil c. A curving magnet H is supported over the coil to adjust the position of the smaller magnet in the chamber.
Pagina 59 - ... coil of wire ; in the siphon recorder a light coil of wire moves between the poles of a powerful magnet. The signal currents pass through the suspended coil to earth, and in doing so the coil turns to left or right, according as the currents are positive or negative. These movements of the coil are communicated by a connecting thread to a fine glass siphon, which is constantly spurting ink upon a band of travelling paper, and hence the trace of the ink on the paper follows and delineates the...
Pagina 66 - Bell of improving the operation of his harmonic telegraph by causing the transmitting interrupters each to make and break the primary circuit of an induction coil, the secondary circuit of which could be placed in the main line by the depression of a key.
