Dudley, my Orderly-room sergeant, is leaving next month time-expired so I thought I was conferring a great favour on the boy by promising him the step-up good staff appointment give him a chance to recuperate thoroughly. But no! my young gentleman courteously declines my munificent offer. Nothing must serve him but he must go back to me Irish 'ginthleman' and that d d dissipated scamp of a Yorke."
These generators will be wound to produce an electric pressure of 12,000 volts, raised by means of step-up transformers to 22,000, 40,000, and 60,000 volts, according to the distance of transmission. Each of the revolving parts of these machines will weigh 141,000 pounds. To what gigantic proportions has the little infant dynamo of Faraday grown in this short time since its birth!
The crossing and bracing wires of the frame are used for sending wires, and in place of ground conductors there are trailers which hang below the aeroplane. The current is derived directly from the engine, and the remaining things needed are a small step-up transformer, a key and a few other small parts.
Now as you know it is easy to step-up a 110 volt alternating current to any voltage you wish with a power transformer but until within comparatively recent years an alternating current could not be used for the production of sustained oscillations for the very good reason that the state of the art had not advanced that far.
This latter device may be either a telephone induction coil, a microphone transformer, or a magnetic modulator; the first two of these devices step-up the voltage of the battery current and the amplified voltage thus developed is impressed on the oscillations that surge through the closed oscillation circuit or the aerial wire system according to the place where you connect it.
Barely touched 'em current something less than a thousandth of a micro-ampere on a million to one step-up. However, it proves our ideas are O. K." The next day Skylark III was running on Eastern Standard Time, of the Terrestrial United States of America the two mathematicians covered sheet after sheet of paper with computations and curves.

There are various methods of producing the alternating current for transmission purposes. In some cases the generators are themselves wound for high potential; in others they are wound for 80 volts, and step-up transformers are used, carrying the current up to whatever pressure is desired, from 1,000 to 10,000 volts.
A fourteen-year-old stripling sprang down to help her but she managed the step-up without his hand. She was taken at once, and almost literally, into the bosom of the family, three boys, a withered father, a work-faded mother, all with curious, kindly eyes. They felt she was not their order, perhaps.
