The current enters the electro-magnet through a fine copper wire hidden in the leaves and connected with the positive pole of the pile. The negative pole is connected with the bottom of the pot. The wire from the vibrator of each insect reaches the bottom of the flower-pot, but does not touch it. A drop of mercury occupies the bottom of the pot, where it is free to move about.
Changing the Primary Spark Coil Current Into Secondary Currents. Now every time the vibrator contact points close the primary circuit the electric current in the primary coil is changed into closed magnetic lines of force and as these cut through the secondary coil they set up in it a momentary current in one direction.
In other words, he invented a telegraph instrument having a vibrator controlled by electrochemical decomposition, to take the place of a vibrating armature operated by an electromagnet, and thus opened an entirely new and unsuspected avenue in the art.
The little office was crowded with busy clerks when I opened my eyes the next morning. Casting a rapid glance at the clock, I saw it was almost eight. There was no time to lose. I grasped the useful little vibrator with one hand, flung the blanket into a corner with the other, and set off, calling to the native servant to follow with a ladder.
It will be seen that the hands are provided at the extremity with a small spring, r, which is itself provided with a small platinum contact, p. The pins also carry a small platinum or silver point, a. It will be seen that, according as the plug, B, is introduced into the aperture to the left or right, the bell. S, will operate as an ordinary vibrator, or give but a single stroke.
The following experiment illustrates notably the movement of the electric waves through free space: "December 26, 1875. Etheric Force. An experiment tried to-night gives a curious result. A is a vibrator, B, C, D, E are sheets of tin-foil hung on insulating stands. The sheets are about twelve by eight inches.
With Direct Current. When a 110 volt direct current is used to energize the power transformer an electrolytic interruptor is needed to make and break the primary circuit, just as a vibrator is needed for the same purpose with a spark coil.
Then she turned her head slowly from right to left to see if she could. "Help me down, somebody," she said in a thin voice, "and call an osteopath. There is something wrong with my spine!" She was in bed three days, having massage and a vibrator and being rubbed with chloroform liniment. At the end of that time she offered me her divided skirt, but I refused.
The result is that the low voltage direct current of the battery is changed into alternating currents whose frequency is precisely that of the spring vibrator, but while the frequency of the currents is low their potential, or voltage, is enormously increased. What Ratio of Transformation Means.
Edison's experiments were repeated by Mr. After recording a considerable number of other experiments, the laboratory notes go on to state: "November 30, 1875. Etheric Force. We found the addition of battery to the Stubb's wire vibrator greatly increased the volume of spark. "December 3, 1875. Etheric Force.
