This is possible if theoscillator frequency is continuously decreased to keep it in synchronism with the decreasing rotational frequency of the ions.
This is to prevent the oscillator from exciting lateral rf resonances.
Think of the tower of the oscillator as a tube, and of the great mushroom-shaped top of the plant as another ball.
For our oscillator proper, we make a few turns of a stout cable around a cylindrical or drum-shaped form, and connect its two ends with the source of electrical energy.
All of these were worked from a distance by wireless impulses, sent by an oscillator to the circuit in the boat through which magnets and other devices operated the interior mechanism.
In the early instruments the wires were set in a horizontal line, and connected to an induction coil, but in the later ones the oscillator was turned up lengthwise with the spark gap between the vertical wings.
When the current is turned on, our oscillatorsends these electrical impulses into the earth and air--or, as the scientists say, into the natural media.
Now from our great alternating current dynamo we first fill the ball at the top of the oscillator with electricity, and then we make a motion that corresponds to squeezing it.
And do not forget that the oscillator and the receiving instrument are so tuned to each other that there is no danger, according to Tesla's scheme, of different oscillators and receivers getting mixed up.
The oscillatoris a self-contained device carried at one end of the shaft.
His apparatus consisted essentially in an oscillator for producing the waves, and a resonator for detecting them.
Wireless telephony, telephony without wires, usually employing electric waves of high frequency emitted from an oscillator or generator, as in wireless telegraphy.
My first transmitter was just an electron coupled oscillatorusing a type 59 output pentode from a radio.
The transmitter was completely 'home brew', consisting of a metal 6L6 Franklin oscillator on 3.
The electron coupledoscillator could not have put more than 4 or 5 watts into the antenna.
His transmitter consisted of a single metal 6L6 crystal oscillator with an input of about 7 watts.
The club transmitter consisted of 4 valves in a Hartley parallel push-pull oscillator circuit which we considered to be of relative 'high power'--perhaps all of 10 watts.
The transmitter was of French manufacture and consisted of two enormous triodes in a Hartley oscillator circuit.
To produce the oscillations he employed the oscillator designed by Augusto Righi.
Wade, will you connect that to the high frequency oscillator there--no--through that counterbalanced condenser.
This put the powerful Arcot oscillator tubes into action, and the power was ready for application.
We may have to change the oscillator frequency quite a bit, but a variable condenser will do that.
If the grid resistor on that oscillatorwent out, for instance, what would it do?
The apparatus he mentioned was simply a high-frequency oscillator tube of extreme power which caused vibrations approaching light frequency to be set up in the molecules of the ship.
Here they heard the soft purring of a large oscillator tube and the indistinguishable murmur of smoothly running AC generators powered by large contraterrene reactors.
This device is used to control the variations of the oscillating currents that are set up by the oscillator tube.
The scheme of modulating an oscillator tube by connecting the secondary of a transformer, the primary of which is connected with a battery and a microphone transmitter, in the grid lead.
Telegraph Transmitting Sets described in Chapter XVII, the oscillator tubes act as rectifiers as well as oscillators but for wireless telephony the alternating current must be rectified first so that a continuous direct current will result.
You can, however, use 110 volt direct current from a lighting circuit as your initial source of power to energize the plate of the vacuum tube oscillator of your experimental transmitter.
A graphic representation of the oscillating currents set up by the incoming waves, those produced by the heterodyne oscillator and the beats they form is shown in Fig.
Telegraph Transmitters with Alternating Current--With Two Oscillator Tubes.
Much of the apparatus for a 50 watt oscillator set where either one or two tubes are used is of the same size and design as that just described for the 5 watt oscillator sets, but, as in the C.
By using two oscillator tubes and connecting them up with the power transformer and oscillating circuits as shown in the wiring diagram in Fig.
The flange of the oscillatoris riveted to the shell of the ship and its diaphragm is caused to vibrate by the sound waves, which pass through water more distinctly than they do through the air.
When we depress the key we start the oscillator going.
These vibrations travel through the water, like wireless waves through the ether, till they strike the oscillator on another vessel and set it to vibrating in sympathy.
I had expected to signal them from the shore, a dock or something of the sort, using this oscillator to get around that fellow's wireless.
Right here," sang out Craig, detaching the oscillatorand replacing the electric bulb, which he lighted.
Among them was one in which he attached to his oscillator a ring magnet with a small air gap between the poles.
I think that beyond doubt it is possible to operate electrical devices in a city through the ground or pipe system by resonance from an electrical oscillator located at a central point.
Thus, he provides properly calculated chambers, as in the case illustrated, in the oscillator itself; or he associates with the oscillator an air spring of constant resilience.
A magnetic frame M M is fastened so as to closely surround theoscillator and is provided with energizing coils which establish two strong magnetic fields on opposite sides.
This jacket acts chiefly to diminish the sound produced by the oscillatorand as a jacket when the oscillator is driven by steam, in which case a somewhat different arrangement of the magnets is employed.
The mechanical efficiency of the apparatus is very high owing to the fact that friction is reduced to a minimum and the weights which are moved are small; the output of the oscillator is therefore a very large one.
With the piston above referred to there is associated in one of his models in an independent chamber an air spring, or dash pot, or else he obtains the spring within the chambers of the oscillator itself.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "oscillator" in a variety of sentences. We hope that you will now be able to make sentences using this word.
