Breathlessly, their eyes flicking back and forth from the solar clock to the magnascope, they waited for the red hand to sweep around. "Here it comes," said Tom excitedly. "One second two seconds three four five!" On the surface of the planetoid, giant mushrooming clouds appeared climbing into the airless void. One by one the reactor units exploded. Connel counted them as they blew up.
He seems to think the two of you wouldn't get along." "On the contrary, skipper," said Roger, "I'd like the opportunity of keeping an eye on him." Strong thought a moment. "Not a bad idea, Roger," he said as he turned to Astro. "And I suppose you want to ride with Kit and his reactor?" Astro grinned. "Yes, sir. If I may." "All right. Tom, I guess that means you ride with Wild Bill Sticoon."
Whenever a calf is born of a reactor, it should be separated from the mother and fed milk from a healthy cow. The separation of the tubercular from the healthy cows must be complete. Separate buildings, yards and pastures that do not join the quarters where the healthy animals are kept should be provided.
"That would mean," asked Roger, "that we'd be here when the reactor units go off, wouldn't it, sir?" "That's right, Manning," said Connel, admitting to the danger. "Even if Junior were blasted out of the pull of the sun, we couldn't survive the explosions." "Couldn't we blast off in the jet boat and then land after the explosions, sir?" asked Astro. "Yes," admitted Connel, "we could do that.
"Kit's problem," commented Tom, "is not so much building the reactor, but a cooling system to keep it under control." "Will that make a big difference in who wins the race?" asked Roger. "With that ship of Kit's," said Astro, shaking his head, "I doubt if he'll be able to come even close to the top speeds in the trials unless he can use the new reactor."
But when the positive half of an alternating current is made to flow through a large inductance it acts like a large resistance as before and likewise smooths out the current, but none of its energy is wasted in heat and so a coil having a large inductance, which is called an inductive reactance, or just reactor for short, is used to smooth out, or filter, the alternating current after it has been changed into a pulsating direct current by the rectifier tubes.
Now, the details of the race will be given to your chief pilots, crew chiefs, and power-deck officers at a special meeting in my office here in the Tower building tomorrow. You will receive all information and regulations governing the minimum and maximum size of the ships entered, types of reactor units, and amount of ballast to be carried." "How many in the crew?" asked a man in the front.
"Fine," said Connel. "That gives me just enough time to notify Space Academy to get ready to receive Junior's signal. You know what to do?" "I don't have to do anything, sir," answered Tom, nodding to the solar clock over his head. "In nine minutes and twenty seconds, the reactor units go off automatically at one-second intervals." Roger and Astro entered the control deck and came to attention.
Where a single tube is used as an oscillator and a second tube is employed as a modulator, a reactor, which is a coil of wire wound on an iron core, is used in the plate circuit to keep the high voltage direct current of the motor-generator the same at all times. Likewise the grid circuit reactor is used to keep the voltage of the grid at a constant value. Connecting up the Apparatus.
The pulsating direct currents are then passed through a filtering reactance coil, called a reactor, and one or more condensers, and these smooth them out until they approximate a continuous direct current.
