The latter is, in this form of turbine, made in the shape of a paddle-wheel of very small circumference but considerable length, the paddles being set at such an inclination as to obtain the greatest possible rotative impulse from the outward-rushing steam.
In practice these latter movements are always curves of more or less complicated form, which effect a considerable modification in the forms of buckets, etc., but not in the general principles, and it is the duty of the designer of any form of turbine to give this consideration its due importance.
What do you want to look at it for?" "It's the motor-boat those fellows had who tried to get away with your turbine model invention, dad. The one they used at the old General Harkness mansion, in the woods near the lake, and the same boat that fellow used when he got away from me the day I was chasing him here." "Oh, yes, I remember now. But what is the boat doing over at Lanton?"
Impinging upon the second row of stationary blades 3, the direction of flow is diverted so as to make it impinge at a favorable angle upon the second row of revolving blades 4, and the action is continued until the steam is expanded to the pressure of the condenser or of the medium into which the turbine finally exhausts.
Times had changed for Kedzie indeed when the little beggar from the candy-store who had cried once when Skip Magruder, the bakery waiter, refused to take her to the movies twice in one Sunday, was crying now because her miser of a husband forbade her a turbine yacht as a plaything. She was crushed with chagrin and she felt completely absolved of the last obligation.
Perhaps the only feature against it is its lack of simplicity of construction and corresponding costliness. The turbine and generator spindle ends, A and B, have toothed heads C and D shrunk upon them, the heads being secured by the nuts E and F. The teeth in this case are cut in the enlarged ends as shown.
Now, my dear, don't worry about it you have never known me to fail, and I won't now. Besides, you forget my successes, Sallie the turbine water-wheel and the others. It will all come, right." "It will never come right." She had risen from her seat, and was standing over, him, both hands on his shoulders, her eyes looking down into his, her voice trembling. "Oh, Richard, Richard!
In relation to this view, it may suffice to note that theoretical deductions have frequently been based upon a generalization that "streams of water must enter the buckets of a turbine without shock, and leave them without velocity." Both these assumed conditions are misleading, and it is now well known that in every good turbine both are carefully disobeyed.
Of course the test was only one to see if the engine worked, for the boat could not move until in the water. The professor opened a valve. The steam filled the turbine with a hiss and throb. The Porpoise trembled. Then, with a cough and splutter of the exhaust pipes, the engine started.
She put them with the others, rather dazed. To Cecil the journey had been a series of tragedies. Not his own. There were two hundred of them, officers and men, on the boat across the Channel. Blind, maimed, paralysed, in motley garments, they were hilariously happy. Every throb of the turbine engines was a thrust toward home. They sang, they cheered.
