TWO:He helped her out. "I have drifted in a way," he went on to explain. "I left home when I was a mere boy, and the spirit of savagery and unrest laid hold of me. I can't break away. And I'm not even sure that I want to. You, I dare say, can't understand." Yet he felt so sure, for some reason, that she could that he[Pg 71] merely nodded his head when she said briefly, "I can." "Then, too," he went on, "there is something in the Indian character that strikes a responsive chord in me. I come of lawless stock myself. I was born in Sidney." Then he stopped short. What business was it of hers where he had been born? He had never seen fit to speak of it before. Nevertheless he intended that she should understand now. So he made it quite plain. "Sidney was a convict settlement, you know," he said deliberately, "and marriages were promiscuous. My grandfather was an officer who was best away from England. My grandmother poisoned her first husband. That is on my mother's side. On my father's side it was about as mixed." He leaned back, crossing his booted legs and running his fingers into his cartridge belt. His manner asked with a certain defiance, what she was going to do about it, or to think.

Hydrocyclone (liquid cyclone)02

A hydrocyclone (liquid cyclone) injects treatment solution into stationary equipment to perform separation, classification, and concentration, and is an innovative separator with a very simple structure and no drive unit.

Structure of a hydrocyclone (liquid cyclone)

A suspension containing fine particles of several micrometers or more is supplied to a cylindrical container circumferentially at high speed. And as a result it starts to rotate and a centrifugal force is generated. At this time a gravitational acceleration of several tens of thousands of G is generated in the circumferential direction, and thus leading to fast sedimentation and concentration of the fine particles. The separated concentration can be freely selected by changing the supply rate (supply pressure and flow rate) and the flow ratio of the outlet. Our hydrocyclone (liquid cyclone) was designed and manufactured to classify and concentrate fine particles, and so has a small element.

THREE:"It's six one, and half a dozen the other. They'd be willing enough to die out in peace, if we'd let them. Even they have come to have a vague sort of instinct that that's what it amounts to.""That will do," said Landor. "See there is no delay," and he wheeled about and went back to his tent with Brewster.
  • Equipment costs can be reduced.
  • Operating costs can be reduced.
  • Maintenance costs can be reduced.
  • Any change in raw material and product can be easily addressed.
  • Large amounts can be treated in a small area.
  • Separation and cleaning are easy because of the simple structure.
  • Simplified control
  • This equipment can be operated in synchronization with external devices.
  • Alarm and interlock mechanism.
THREE:But it is because of just this that no scion of ultra-civilization degenerates so thoroughly as does he. Retrogression is easy to him. He can hardly go higher, because he is on the height already; but he can slip back. Set him in a lower civilization, he sinks one degree[Pg 266] lower than that. Put him among savages, and he is nearer the beasts than they. It does not come to pass in a day, nor yet at all if he be part of a community, which keeps in mind its traditions and its church, and which forms its own public opinion. Then he is the leaven of all the measures of meal about him, the surest, steadiest, most irresistible civilizing force. But he cannot advance alone. He goes back, and, being cursed with the wisdom which shows him his debasement, in loathing and disgust with himself, he grows sullen and falls back yet more.
