TWO:"I say we can't give it to you now," Miss Harper persisted, with a motherly smile; "we're wearing it ourselves. We've had no time to take it off. I couldn't get the boots off me last night. And even if you had the boots, the other things--"

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:As the description of the First National Fair at Tokio may not be uninteresting, we will copy from a letter to a New York paper, by one of its correspondents who was in Japan at the time. After describing the opening ceremonies, which were attended by the emperor and empress, together with many high dignitaries of the government, he wrote as follows:There were more attractions outside the temple than in it for our young visitors, and, after a hasty glance at the shrines in the neighborhood of the great altar, they went again into the open air.
  • 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:Dear me, this is absolute starvation, he exclaimed. I should have eaten my scones.As the boys rode along, their attention was drawn to some tall ladders that rose above the buildings, and they eagerly asked the Doctor what those ladders were for. They could not see the use of climbing up in the air and then coming down again; and, altogether, the things were a mystery to them. A few words explained the matter. The ladders were nothing more nor less than fire-lookouts, and were elevated above the buildings so that the watchmen could have an unobstructed view. A bell was attached to each ladder, and by means of it a warning-signal was given in case of a threatened conflagration. Fires are frequent in Tokio, and some of them have done immense damage. The city is mostly built of wood; and when a fire breaks out and a high wind is blowing, the result is often disastrous to an enormous extent.
