TWO:On the 14th of September the Russian army filed through the streets of their beloved but doomed city, with sad looks, furled banners, and silent drums, and went out at the Kolomna gate. The population followed them. Rostopschin had encouraged vast numbers already to transplant all their wealth and stores from the place, and, as his last act, he called up two prisonersa Russian traitor, and a Frenchman who had dropped hostile expressions. The Russian he ordered, with the consent of the culprit's own father, to be put to death; the Frenchman he set at liberty, telling him to go to Buonaparte and say that but one traitor had been found in Russia, and him he had seen cut to pieces. Rostopschin then mounted his horse and rode after his countrymen, having first[47] ordered all the gaols to be set open, and their wretched inhabitants to be allowed to make their escape.

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:CHAPTER IV. Reign of George II. (continued).During these proceedings, the National Assembly was sitting at Versailles in the utmost agitation. On the morning of the 13th, Mounier had risen and censured the dismissal of the Ministers, and had been seconded by Lally Tollendal, who had pronounced a splendid panegyric on Necker, and recommended an address to the king for his recall. M. de Virieu, a deputy of the noblesse, proposed to confirm by oath the proceedings of the 17th of June; but Clermont Tonnerre declared that unnecessary, as the Assembly had sworn to establish a constitution, and he exclaimed, "The Constitution we will have, or we will perish!" In the midst of this discussion came the news of the rising of the people of Paris, on the morning of the 13th, and an address was immediately voted to the king, beseeching him to withdraw the foreign troops, and authorise the organisation of the Civic Guards. The Duke de la Rochefoucauld said, the foreign troops in the hands of despotism were most perilous to the people, who were not in any one's hands. The address was sent, and the king returned a curt answer, that Paris was not in a condition to take care of itself. The Assembly then assumed a higher tone, asserted that the present counsellors of the king would be responsible for all the calamities which might take place, and declared itself in permanent session, that is, that it would sit day and night till the crisis was over. It appointed M. de Lafayette vice-president, in the place of the aged Bishop of Vienne, who was not capable of much exertion.
  • Equipment costs can be reduced.
