SYNCHRONOUS MACHINES. INDUCTION MOTORS. DIRECT-CURRENT MACHINES.

Dawn was breaking now, and here and there a Chinese was taking down the shutters of his shop. In its dark recesses, by the light of a taper, a woman was washing her hands and face. In a tea-house at a corner a group of men were eating an early meal. The grey, cold light of the rising day sidled along the narrow lanes like a thief. There was a pale mist on the river and the masts of the crowded junks loomed through it like the lances of a phantom army. It was chilly as they crossed and Kitty huddled herself up in her gay and coloured shawl. They walked up the hill and they were above the mist. The sup shone from an unclouded sky. It shone as though this were a day like another and nothing had happened to distinguish it from its fellows.

"Wouldn't you like to lie down?" said Waddington when they entered the bungalow.

"No. I'll sit at the window."

She had sat at the window so often and so long during the weeks that had passed and her eyes now were so familiar with the fantastic, garish, beautiful and mysterious temple on its great bastion that it rested her spirit. It was so unreal, even in the crude light of mid-day, that it withdrew her from the reality of life.

"I'll get the boy to make you some tea. I'm afraid it will be necessary to bury him this morning. I'll make all arrangements."

"Thank you."

Chapter LXV

They buried him three hours later. It seemed horrible to Kitty that he must be put into a Chinese coffin, as though in so strange a bed he must rest uneasily, but there was no help for it. The nuns, learning of Walter's death as they learned everything that happened in the city, sent by a messenger a cross of dahlias, stiff and formal, but made as though by the accustomed hands of a florist; and the cross, alone on the Chinese coffin, looked grotesque and out of place. When all was ready they had to wait for Colonel Yü, who had sent to Waddington to say that he desired to attend the funeral. He came accompanied by an A.D.C They walked up the hill, the coffin borne by half a dozen coolies, to a little plot of land where lay buried the missionary whose place Walter had taken. Waddington had found among the missionary's effects an English prayer-book and in a low voice, with an embarrassment that was unusual to him, read the burial service. Perhaps, reciting those solemn but terrible words, the thought hovered in his mind that if he in his turn fell a victim to the pestilence there would be no one now to say them over him. The coffin was lowered into the grave and the grave-diggers began to throw in the earth.

Colonel Yü, who had stood with bared head by the graveside, put on his hat, saluted Kitty gravely, said a word or two to Waddington and, followed by his A.D.C, walked away. The coolies, curious to watch a Christian burial, had lingered and now in a straggling group, their yokes trailing in their hands, sauntered off. Kitty and Waddington waited till the grave was filled and then placed on the mound, smelling of fresh earth, the nuns' prim dahlias. She had not wept, but when the first shovelful of earth rattled on the coffin she felt a dreadful pang at her heart.

She saw that Waddington was waiting for her to come away.

"Are you in a hurry?" she asked. "I don't want to go back to the bungalow just yet."

"I have nothing to do. I am entirely in your hands."

SYNCHRONOUS MACHINES. INDUCTION MOTORS. DIRECT-CURRENT MACHINES.

Subtechnical vocabulary

armature ( noun)

a part of a generator, motor that turns around to produce electricity

The armature is a unit in which an EMF is induced.

synchronous ( adjective)

happening at exactly the same time

All large synchronous generators are made with a revolving field.

engine (noun)

a piece of machinery with moving parts that changes power from steam, electricity,

oil into movement.

Engines are of different modifications.

mover ( noun)

a natural force, such as wind or water, that can be used to produce power

The prime mover of a synchronous may be a steam engine.

wheel (noun)

something round which turns when it moves

The prime mover of a synchronous generator may be a water wheel.

torque (noun)

the force or power that makes something turn around a central point, especially in an

engine

The purpose of the auxiliary winding is to produce starting torque.

cast (verb)

to pour liquid metal into a moulder ( specially shaped container)

The whole structure is held in a frame which may be of cast iron or welded steel plate.

weld (verb)

to join metals by melting them and pressing when they are hot

We can join two different metals by welding under high temperatures

slot ( noun)

a long narrow hole made in a surface

The armature has slots which receive the armature winding.

excite (verb)

to make something to increase its activity

The direct current requires exciting the field structure.
