It talks right out in meeting, too no transmitter to hold to the mouth, no receiver to hold to the ear. You see, this transmitter is so sensitive that it picks up even a whisper, and the receiver is placed back of those two megaphone-like pyramids." He was standing at a table, carefully packing up one of the vocaphones and a lot of wire.

I seized the telephone at my elbow, pressing upon the button which would call the chief engineer to the instrument in the bowels of the ship, only to find him already at the receiver attempting to reach me. "Numbers one, two, and five engines have broken down, sir," he called. "Shall we force the remaining three?" "We can do nothing else," I bellowed into the transmitter.

Trigger said. The transmitter signaled for attention while she was studying the report. Holati Tate went off to answer it. The report was rather lengthy, and Trigger was still going over it when he got back. He sat down again and waited. When she looked up finally, he asked, "Can you make much sense of it?" "Not very much," Trigger admitted. "It just states what seems to have happened.

The Operation of the Key Circuit. The effect in a C. W. transmitter when a telegraph key is connected in series with a buzzer and a battery and these are shunted around the condenser in the grid circuit, is to rapidly change the wave form of the sustained oscillations, and hence, the length of the waves that are sent out.

It is built on exactly the same lines as the experimental transmitter just described, but instead of using a 100 volt plate amplifier as a makeshift generator of oscillations it employs a vacuum tube made especially for setting up oscillations and instead of having a low plate voltage it is energized with 350 volts. The Apparatus You Need.

Bell had six of these instruments tuned to as many different pitches and six receivers to answer them you may picture to yourself the hideousness of the sounds amid which the experimenters labored." "I suppose when each transmitter sent out its particular whine its own similarly tuned receiver spring would wriggle in response," Laurie said. "Exactly so."

A single apparatus at each end is therefore sufficient, performing the double function of transmitter and receiver. It will be noticed that in this arrangement no battery is used The strength of the impulses transmitted is therefore limited to that of the necessarily weak induction currents generated by the original sounds minus any loss arising by reason of resistance in the line.

And he preferred Ursula to be there, as a sort of transmitter to Gudrun. 'Do you do nothing but architectural sculpture? Gudrun asked him one evening. 'Not now, he replied. 'I have done all sorts except portraits I never did portraits. But other things 'What kind of things? asked Gudrun. He paused a moment, then rose, and went out of the room.

It's nice to see that homely old mug again!" "Be a lot nicer when it won't have to be over a transmitter." "Right you are!" "When are you coming back?" She shook her head glumly. "Don't know." He was silent a moment. "I've had to take a bit of chitchat now and then," he remarked, "about you and old Tate vanishing together." Trigger felt herself coloring. "So don't take it," she said shortly.

On May 23, 1844, the line was complete. Remembering his promise to Miss Ellsworth, Morse called upon her next morning to give him the first message. She chose, "What hath God wrought?" and early on the morning of the 24th Morse sat at the transmitter in the Supreme Court room in the Capitol and telegraphed these immortal words to Vail at Baltimore.
