TWO:Hong-kong, being an English colony, is governed after the English form, and consequently the laws enforced in China do not necessarily prevail on the island. The population includes four or five thousand English and other European nationalities, and more than a hundred thousand Chinese. The number of the latter is steadily increasing, and a very large part of the business of the place is in their hands. The money in circulation is made in England for the special use of the colony. It has the head of the Queen on one side, and the denomination and date on the other; and, for the accommodation of the Chinese, the denomination is given in Chinese characters. The smallest of the Hong-kong coins is made to correspond with the Chinese cash, and it takes ten of them to make a cent, or one thousand for a dollar. It has a hole in the centre, like the Chinese coins generally, to facilitate stringing on a wire or cord, and is so popular with the natives that it is in free circulation in the adjacent parts of the empire.

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:What was he going to do next? He had[Pg 22] reached to the end of the field and stopped abruptly. Apparently, the presence of another barrier acted as a complete check to further movement. For several seconds he remained perfectly still. He was now about a hundred yards from Arthur, but the latter had good eyesight, and he was determined to miss nothing.I understand, he said. And what you have said much increases my regret at the election going as it did. He paused a moment, evidently thinking, and Keeling, had an opportunity to wager been offered him, would have bet that his next words would convey, however delicately, the hope that Keeling would reconsider his letter{276} of the morning, announcing the termination of the Clubs lease. He was not prepared to do anything of the sort, and hoped, indeed, that the suggestion would not be made. But that he should have thought that the suggestion was going to be made showed very precisely how unintelligible to him was the whole nature of the class which Lord Inverbroom represented. No such suggestion was made, any more than half an hour ago any idea of a fresh election being held was mooted.
  • Equipment costs can be reduced.
