In the limits of a short paper it is impossible to do justice to more than one aspect of the considerations relating to turbines, and it is now proposed to bring before the Mechanical Section of the British Association some conclusions drawn from the behavior of jets of water discharged under pressure, more particularly in the hope that, as water power is extremely abundant in Canada, any remarks relating to the subject may not fail to prove interesting.
Beyond them rose workshops, their machinery driven by electric power from the turbines at the rapids. Even as Allan and Beatrice passed through the cheering crowd, now drifting toward the hangars, a sound of music wafted down-wind a little harsh at times, but still with promise of far better things to be.
He said that of course they would prefer to buy them abroad, but that, though this was impossible, the work would not be delayed on that account, since they could make a start with the machines they had. Turbines for the Petrograd works they still hoped to obtain from abroad when peace had been arranged. If the worst came to the worst he thought they could make their own.
Then Strang bade them farewell and good luck, the engines began to move, the screw churned the water, and the prize, heading westwards, sped rapidly towards the mouth of the Straits. Williams, who was the sort of man who could tackle anything in the way of machinery, from a sewing machine to a Dreadnought's turbines, soon got the hang of the launch's engines.
At Kobe one can often see a whole mountain of wooden boxes containing matches, waiting for shipment to China and Korea. So it is in all other branches of industry. The Japanese travel to Europe and study the construction of turbines, railway carriages, telephones, and soon they can dispense with Europe and produce all they want themselves.
An absolutely pure mineral oil must be supplied, of a non-foaming character, and it should be kept free through filtering from any impurities. The above refers particularly to Allis-Chalmers turbines of the type ordinarily used for power service. For turbines built to be run non-condensing, the part relating to vacuum does not, of course, apply.
Preparing the Turbine for Testing All preliminary labors connected with a test being satisfactorily disposed of, it only remains to place the turbines under the required conditions, and to then proceed with the test. For the benefit of those inexperienced in the operation of large turbines, we will assume that such a machine is about to be started for the purpose outlined.
Much has already been done in this direction. In 1891 the power of turbines driven by the Falls of Neckar at Lauffen was transformed into electricity, and transmitted by a small wire to the Electrical Exhibition of Frankfort-on-the-Main, 117 miles away. The city of Rome is now lighted from the Falls of Tivoli, 16 miles distant.
You should keep abreast of the age, my dear fellows. We might have settled it long ago, if you'd only spoken. Yes, four good turbines and a neat brick penstock eh? This old Wheel's absurdly out of date." "Well," said the Cat, who after a little proud seclusion had returned to her place impenitent as ever.
Our power is obtained by the combustion of gases in highly efficient turbines. It is transmitted and used as direct current, our generator and motors being so constructed that they can produce no etheric disturbances capable of penetrating the shielding walls of our city.
