Mary, who was no less conventional, and no more intelligent, yet led a larger life and held more tolerant views. There was good in the new order too. The telephone clicked, and Archer, turning from the photographs, unhooked the transmitter at his elbow. How far they were from the days when the legs of the brass-buttoned messenger boy had been New York's only means of quick communication!
The Tractosaur was a "thinking bulldozer" the Spindrift scientists had designed. Barby continued, "I know you can make a small transmitter that will fit in your pocket, because that's all the Tractosaur control was, really. Well, if I wore a receiver that no one could see, and if you carried a transmitter that no one could see, we could put on the most wonderful mind-reading act in history!"
"Another friend of mine, Jim Liverios, was employed at the Civil Aviation transmitter site on a hill south of Nea Smyrni. The American Mission had set up their short wave transmitters on the same site and later Interpol installed their own equipment as well. Liverios was always on night shift because he attended the University during the day.
Joyce tuned the clatter down to a faint clicking, and switched his transmitter on. "You're on, Captain," he said. "This is Captain Greylorn, UNACV Galahad; kindly identify yourself." I repeated this slowly, half a dozen times. It occurred to me that this was the first known time in history a human being had addressed a non-human intelligence.
With the murmuring bush about us in the clear space kept always cleared beneath those quivering wires, we stood all dressed in white, first looking up at the operator as, clinging to his pole, he tapped the line, and then looking down at him as he knelt at our feet with his tiny transmitter beside him clicking out our message to the south folk.
In this warfare, the possession of a good battery transmitter counted very heavily in favor of the Western Union, for upon that the real expansion of the whole industry depended; but in a few months the Bell system had its battery transmitter, too, tending to equalize matters.
His most conspicuous discovery is that pressure diminishes the resistance of contact between two conductors, a fact which Clerac in 1866 utilised in the construction of a variable resistance from carbon, such as plumbage, by compressing it with an adjustable screw. It is also the foundation of the carbon transmitter of Edison, and the more delicate microphone of Professor Hughes.
I fancied that there was a puzzled expression on his face, as he placed his hand over the transmitter and said to Carton, "Here it's for you. Take it. By the way, where's that thing I left down here for recording voices?" "Here in my desk. But you took the cylinder with you." "Haven't you got another? Don't you ever use them for dictating letters?"
For this small transmitter you can use an ordinary buzzer as shown at F. A dry cell or two must be used to energize the buzzer. You can get one for about 75 cents. The Telegraph Key. Any kind of a telegraph key will serve to break up the trains of sustained oscillations into dots and dashes. The key shown at G is mounted on a composition base and is the cheapest key made, costing $1.50.
With an officer in the observation post, we could not carry on the kind of conversation that's usual between two mates, so we used the Morse code. To send, one of us would tap the transmitter with his finger nails, and the one on the other end would get it through the receiver. Many an hour was whiled away in this manner passing compliments back and forth.
