One of the ends of the secondary of the induction coil, or the microphone transformer, or the magnetic modulator is connected to the grid circuit and the other end to clip 3 of the tuning coil. A 100 to 200 Mile Wireless Telephone Transmitter With Direct Current Motor Generator.
And he had added a dozen more items to the lengthening list of what Zarathustra could now produce in adequate quantities and no longer needed to import. Not fishhooks and boot buckles, either blasting explosives and propellants, contragravity-field generator parts, power tools, pharmaceuticals, synthetic textiles.
The tremendous mass of the nose of the Thessian ship had caught them full amid-ship, and the powerful ram had driven through the room. Their lux walls had not been touched; only a sledge-hammer blow would have bent them under any circumstances, let alone breaking them. But the tremendously powerful main generator was split wide open. And the mechanical damage was awful.
The drone of the fleeing super-planes diminished and was gone, and for a time the thrum of the generator and the tap-dance of relays adjusting circuits was the only sound aboard. Wade sighed finally. "Well, gentlemen, now we've got it, what do we do with it?" "What do you mean?" Morey asked. "Victory. The Jack-pot.
Griselda carries spare set of Hofman racing vans and can be lied three foot clear in smooth water with ballast-tank swung aft. The others do not lift, clear of water, and are recommended for beginners. Maginnis motor, Radium relays and Pond generator. Bronze breakwater forward, and treble reinforced forefoot and entry.
And a ten-foot wavering flame of blue-white, bellying electric fire shuddered up to the ceiling from the contact points of the alleged atomic generator. The heat, pouring out from the flashing, roaring arc sent prickles of aching burns over Kendall's skin. For ten seconds he stood in utter, paralyzed surprise as his flop of flops bellowed its anger at his disdain.
The air, too, became foul and heavy, for the pumps could not replace it with a fresh supply from the near-vacuum outside. Oxygen tanks had not been carried on this trip. As the power of the generator was being used to warm the cabin once more, they began to fall.
The generator slave looked up, startled, but when Jason glanced at him he lowered his eyes and kept cranking. The man who had been working the transmitter spun about, startled by the slam of the door and the muffled pounding and shouts that followed instantly from the other side.
The analogy of the wireless transmitter of intelligence may be misleading if applied to the question of power. The practicability of wireless telegraphy depends upon the marvellous susceptibility of the "coherer," which enables it to respond to an impulse almost infinitesimally small, certainly very much smaller than that despatched by the generator from the receiving station.
So far as the generator is concerned, it is only essential to follow the practice common in all electric power plant operation, which need not be reviewed here.
