In using a counterpoise you must bring the wire from it up to and through another leading-in insulator to your instruments. With a crystal detector receiving set you can receive either telegraphic dots and dashes or telephonic speech and music. You can buy a receiving set already assembled or you can buy the different parts and assemble them yourself.
We called him "Flagstaff," and cracked all sorts of jokes about putting an insulator on his head, and setting him up for a telegraph pole, braiding his legs and using him for a whip lash, letting his hair grow a little longer, and trading him off to the Rebels for a sponge and staff for the artillery, etc.
And the Venus Central State has been attacked and has fallen. An assassination on Mars, and three here on Earth all simultaneously. It's one gigantic plot, I tell you and the Cold Country of Venus is at the bottom of it." Georg jumped to his feet. "I'll see if the room has been tampered with." He was back presently. "The insulator is intact. I set the alarm bell. If she touches it "
What I have just said may afford an explanation of the phenomenon observed by Prof. Crookes, namely, that a discharge through a bulb is established with much greater facility when an insulator than when a conductor is present in the same.
Experiments already referred to had taught him that this substance, though an insulator when solid, is a conductor when fused, the passage of the current being always accompanied by the decomposition of the chloride. He wished to ascertain what relation this decomposition bore to that of the water in his voltameter.
The inner star of twelve copper wires is the conductor, and the black circle round it is the gutta-percha or insulator which keeps the electricity from escaping into the water.
It was a complete success, and lasted until the line was abandoned. Mr. Wade also invented, in 1852, what is now known as the Wade insulator, which has been used more extensively, perhaps, than any other. Among the strong points in Mr. Wade's character, is his readiness and ability to adapt himself to whatever he undertakes to do.
Now if you intend to use the air gap lightning arrester fasten it to the wall of the building outside of your window, and bring the leading-in wire from the aerial to the top binding post of your arrester and keep it clear of everything as shown at B. If your aerial is on the roof and you have to bring the leading-in wire over the cornice or around a corner fix a porcelain knob insulator to the one or the other and fasten the wire to it.
"The next night about 1 A.M. this operator, on the press wire, while I was standing near a House printer studying it, pulled out a glass insulator, then used upside down as a substitute for an ink-bottle, and threw it with great violence at me, just missing my head. It would certainly have killed me if it had not missed.
The exhaust from the engine heat pumps was reversed, and run out through a hole hastily knocked in the side of the wall. Naturally, we let it flow too fast at first. Space is a vacuum, which means it's a good insulator. We had to cut the air down to a trickle. Then Wilcox ran into trouble because his engines wouldn't cool with that amount of air.
