With this spectacular demonstration he administered the deathblow to all plans for high power ultra-long-wavelength transmitters, and from then on the commercial companies concentrated their efforts on developing equipment for international communications on the short waves.
She had actually felt that bewilderment of his when, just before they had reached the station, she had responded passionately to his last embrace. Even as he returned her caresses, it had been conveyed to her amazingly by the quality of his touch. Was it a lack all women felt in men? and were these, even in supreme moments, merely the perplexed transmitters of life? not life itself?
Now there is only one method by which currents of high frequency, or radio-frequency, as they are termed, can be set up by spark transmitters, and this is by discharging a charged condenser through a circuit having a small resistance.
The Commissioner had swung the transmitter cabinet aside and was back there, prowling among the power leads. "What's wrong?" Trigger asked. "Transmitters went out," he said. "Don't know why yet. Grab some tools and help me check." She slipped on her work gloves, grabbed some tools and joined him. Lyad and Mantelish watched them silently.
Kennedy removed the transmitters of the telephones, and taking the carbon capsules from them placed the capsules on the table carefully. Then he lifted down the etching from the wall and laid it flat on its face before us. Quickly he removed the back of the picture.
"Not if we seal the set here." Trigger nodded. "You'll do the talking," she said. "I'll give you Commissioner Tate's personal number. Tell them to dial it. The Precol transmitters pick up ComWeb circuits. Switch on the screen after the call is in; he'll want to see me. When he comes on, just tell him what's happened, where we are, what the layout is. He's to come over with a squad to get us.
In the wireless telephone transmitters for long distance work which were shown and described in the preceding chapter a battery is used to energize the microphone transmitter, and these two elements are connected in series with a microphone modulator.
And to whom this message was addressed Tom did not say, but we fancy some of our readers can guess. Finally, after several hours of work, the wireless was in shape to send and receive messages. Tom pulled over the lever, and a crackling sound was heard, as the electricity leaped from the transmitters into space. Then he clamped the receiver on his ear. "All ready," he announced.
The system is certainly perfect; for example, over yonder in that sort of cage is the dispatching clerk. The orders, as they are taken by the different departments in the store, are sent by transmitters to him. His assistants sort them and enclose each class in a carrier-box by itself.
The tellers of the stories of which Homer's Iliad was compounded; the transmitters of the legend and history which make up the Gesta Romanorum; the travelling raconteurs whose brief heroic tales are woven into our own national epic; the grannies of age-old tradition whose stories are parts of Celtic folk-lore, of Germanic myth, of Asiatic wonder-tales, these are but younger brothers and sisters to the generations of story-tellers whose inventions are but vaguely outlined in resultant forms of ancient literatures, and the names of whose tribes are no longer even guessed.
