Not to here, of course, but maybe to Careless Mesa or Dry Spring." "We can check when we get back," Rick said. "Come on. We'd better take the town apart and see if the rotor and distributor cap are here." It was midmorning before they gave up the search, and both of them were exhausted. "Now what?" Rick asked wearily. He had never in his life felt so badly in need of sleep.
The other connections are exactly the same as shown in Figs. 44 and 45. An Intermediate Wave Set With Variocoupler Inductance Coils. By using the coil wound on the rotor of the variocoupler as the tickler the coupling between the detector tube circuits and the aerial wire system increases as the set is tuned for greater wave lengths.
This is the part of the variocoupler that is called the stator. The secondary coil is wound on the section of a ball mounted on a shaft and this is swung in bearings on the stator so that it can turn in it. This part of the variocoupler is called the rotor and is arranged so that it can be mounted on a panel and adjusted by means of a knob or a dial. The Variometer.
A radio call from Tom brought a sleek, strange-looking craft zooming up to join them. It was the Sea Hound, latest and largest model of Tom's amazing diving seacopter. It had an enclosed central rotor, powered by atomic turbines, with reversible-pitch blades for air lift or undersea diving. Superheated steam jets provided forward propulsion in either element.
All you have to do is to tune the oscillation circuits to each other is to turn the rotor, which is the secondary coil, around in the stator, as the primary coil is called in order to get a very fine variation of the wave length.

Mount the rotor squarely by the spindle points between two pieces of wood held lightly in the vice, and, with the aid of a gauge fixed to the piece nearest the wheel, true up the line of the vanes. To assist the bending of it into a ring one needs some circular object of the same diameter as the interior diameter of the ring round which to curve it.
Then you ask Tom to send a plane back to drop off my cap and rotor. And tell him to send a walkie-talkie, too. "Now, I got a real good idea what game you boys are playin' and it's fine by me. Only don't get into my game. Stay on the base. You mean well, but you could cross me up when it would hurt most. Some day, after we have the one we want, we'll compare notes.
When the variocoupler is adjusted for receiving very long waves the rotor sets at right angles to the stator and, since when it is in this position there is no mutual induction between them, the tickler coil serves as a loading coil for the detector plate oscillation circuit.
Now connect one end of the secondary coil, or rotor, to one post of a .0007 mfd. variable condenser, the other post of this to one end of the grid coil and the other end of this with the remaining end of the rotor of the variocoupler.
