TWO:"This is the road by which the Tartars went to the conquest of China,[Pg 385] and there is a story that the empire was lost in consequence of a woman. The Chinese were very much afraid of the Tartars, and they built the Great Wall to keep them out of the country. But a wall would be of no use without soldiers to defend it, and so it was arranged that whenever the Tartars were approaching, a signal should be sent along the towers, and the army would come to Pekin to defend it.The Doctor's conclusion may be taken as a fair expression of his character. Naturally, the effect of such a preposterous revelation upon a sluggish and doubting mind would be to arouse it to a kind of furious defence of all that man has been in the past, and a scarcely less spirited rejection of that grotesque possibility of the future which the Clockwork man presented to the ordinary observer. Gregg, on the other hand, may be excused, on the score of his extreme youthfulness, for the impetuosity of his actions. His attempt to persuade the editor of the Wide World Magazine that his version of the affair, put in the shape of a magazine story, was actually founded on fact, ended in grotesque failure. His narrative power was not doubted; but he was advised to work the story up and introduce a little humour before offering it as a contribution to some magazine that did not vouch for the[Pg 194] truth of its tall stories. As this was beneath Gregg's dignity, and he could find no one else to take him seriously, he shut up like an oyster, and just in time to forestall a suspicious attitude on the part of his friends. It was only years later, and after many experiences in this world of hard fact and difficult endeavour, that he began to share the Doctor's view, and to cherish the memory of the Clockwork man as a legend rich in significance.

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:"Who are you?" he demanded, after a preliminary click or two.
  • 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:Norah got up, smiling at him. Her internal blush had filtered through to her face."Arthur was not sure what this term implied. In spite of his confusion he couldn't help feeling a little amused. The figure standing by his side was so exactly like a wax-work come to life, and his talk was faintly reminiscent of a gramophone record.
