TWO:"And so these things come here in cans, do they?" Frank inquired.

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:My heart beat wildly and I wanted to ask if it was on my account; but I was too pusillanimous a coward, and when I feebly tried to look into her eyes she would not let me, which convinced me that she lacked candor. A dance ended. Gold-laced fellows came and sat on the veranda rail wiping wrists and brows with over-tasked handkerchiefs, and explaining the small mishaps of the floor. Two promenaders mentioned the hour. I gasped my amazement and extended my hand. "Good-bye."
  • 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:"What's that to do with the crow?" Fred asked.The train sped onward, and in an hour from the time of leaving the station at Yokohama it was nearing Tokio. It passed in full view of the forts of Shinagawa, which were made memorable during the days of Perry and Lord Elgin, as the foreign ships were not allowed to pass them, and[Pg 108] there was at one time a prospect that they would open fire upon the intruders. Near one of the forts, a boat containing three fishermen was pulling slowly along, one man handling the oar, while the other two were lifting a net. Whether any fish were contained in it the boys did not ascertain, as the train would not stop long enough to permit an investigation. The fort rose from the water like a huge warehouse; it might resist a Chinese junk, or a whole fleet of the rude craft of the East, but could not hold out an hour against the artillery of the Western nations. In recent years the forts of Tokio have been[Pg 109] strengthened, but they are yet far from what an American or English admiral would hold in high respect. The Japanese have made commendable progress in army organization; but, so far as one can learn generally, they have not done much in the way of constructing and manning fortifications.
