TWO:The Prussians, writes Carlyle, tramp on with the usual grim-browed resolution, foot in front, horse in rear. But they have a terrible problem at that Kesselsdorf, with its retrenched batteries and numerous grenadiers fighting under cover. The very ground is sore against them; up-hill, and the trampled snow wearing into a slide, so that you sprawl and stagger sadly. Thirty-one big guns, and near nine thousand small, pouring out mere death on you from that knoll-head. The Prussians stagger; can not stand; bend to rightward to get out of shot range; can not manage it this bout. Rally, re-enforced; try it again. Again with a will; but again there is not a way. The Prussians are again repulsed; fall back down this slippery course in more disorder than the first time. Had the Saxons stood still, steadily handling arms, how, on such terms, could the Prussians have ever managed it?90Lord Hyndford, evidently embarrassed, for the facts were strongly against him, endeavored, in some additional remarks, to assume ignorance of any unfriendly action on the part of the British government. The king again, in a loud and angry tone, replied,

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:At eleven this day I went to the council-chamber for the third time, and desired Secretary Hartoff to prevail with the ministry to allow me to speak with them, and communicate what the King of Prussia had ordered me to propose. Herr von Hartoff gave them an account of my request, and brought me, for answer, that I must wait a little, because the ministers were not yet all assembled; which I did. But after having made me stay almost an hour, and after the president of the council was come, Herr von Hartoff came out to me and repeated what he had said yesterday, in very positive and absolute terms, that the ministers were resolved not to see me, and had expressly forbid him taking any paper at my hands.Immediately after his return he wrote again: I am now a peaceable inhabitant of Reinsberg, applying myself to study and reading almost from morning till night. With regard to the news of this world, you will learn them better through the gazetteers than through me. They contain the history of the madness and folly of the great, the wars of some, the quarrels of others, and the childish amusements of all. These news are as little worthy the attention of a man of sense as the quarrels of rats and mice would be.25
