TWO:It was the usual tale of woe that Geronimo had to tell, much the same that the old buck had recited to[Pg 298] Cairness in the spring of the last year. His particular grievance was the request for his hanging, which he had been told had been put in the papers, and his fear of three White-men who he believed were to arrest him. "I don't want that any more. When a man tries to do right, such stories ought not to be put in the newspapers. What is the matter with you that you do not speak to me? It would be better if you would look with a pleasant face. I should be more satisfied if you would talk to me once in a while." The interpreter translated stolidly. "Why don't you look at me and smile at me? I am the same man. I have the same feet, legs, and hands, and the Sun looks down on me a complete man." There was no doubt about that, at any rate, and perhaps it was not an unmixed good fortune.Then he delivered his ultimatum, slowly, watching the unhappy savage narrowly from under the visor of his pith helmet. "You must make up your mind whether you will stay out on the war-path or surrenderwithout conditions. If you stay out, I'll keep after you and kill the last one, if it takes fifty years. I have never lied to you," he stood up and waved his hand; "I have said all I have to say. You had better think it over to-night and let me know in the morning."

Hydrocyclone (liquid cyclone)01

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:One thing that kept coming into his mind was the strange fact that if the disappearing passenger of the seaplane had taken the rubber boat he had not also taken the hidden jewels.
  • 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:The figure moved into the circle of red firelight and spoke, "It is Cairness."
