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:A succession of battles now took place with varying success, but still leaving the Allies nearer to Paris than before. If Buonaparte turned against Blucher, Schwarzenberg made an advance towards the capital; if against Schwarzenberg, Blucher progressed a stage. To check Schwarzenberg whilst he attacked Blucher, Napoleon sent Oudinot, Macdonald, and Gerard against Schwarzenberg; but they were defeated, and Napoleon himself was repulsed with severe loss from Craonne and the heights of Laon. But Buonaparte getting between the two Allied armies, and occupying Rheims, the Austrians were so discouraged that Schwarzenberg gave orders to retreat. The Emperor Alexander strenuously opposed retreat; but the effectual argument was advanced by Lord Castlereagh, who declared that the moment the retreat commenced the British subsidies should cease. A sharp battle was fought on the 20th of March, between Schwarzenberg and Napoleon, at Arcis-sur-Aube, and Napoleon was compelled to retreat. Blucher, who had received the order to retreat from Schwarzenberg, had treated it with contempt, and replied to it by his favourite word, "Forwards!" Napoleon had now to weigh the anxious question, whether it was better to push on, and stand a battle under the walls of Paris, with his small, much-reduced force, against the Allies, and with the capital in a state of uncertainty towards himor to follow and harass the rear of the enemy. He seems to have shrunk from the chance of a defeat under the eyes of his metropolis, and he therefore, finding a Prussian force in Vitry, crossed the Marne on the 22nd of March, and held away towards his eastern frontiers, as if with some faint, fond hope that the peasantry of Franche Comt and Alsace might rise and fly to his support. But no such movement was likely; all parts of France were mortally sick of his interminable wars, and glad to see an end put to them. The Allies had now taken the bold resolve to march on Paris and summon it to surrender.Great meetings were held in various towns and counties to condemn the whole proceedings, and addresses were sent up and presented to the Prince Regent which were, in fact, censures of his own conduct, and were not, therefore, received in a becoming manner. To one from the Common Council of London he replied that he received it with regret, and that those who drew it up knew little or nothing of the circumstances which preceded or attended the Manchester meeting. The fact was, that they knew these a great deal better than he did. Similar addresses were sent up from Westminster, York, Norwich, Bristol, Liverpool, Birmingham, Leeds, Sheffield, and many other towns. A meeting of the county of York was calculated at twenty thousand persons, and amongst them was the Earl Fitzwilliam, Lord-Lieutenant of the West Riding, who had also signed the requisition to the high-sheriff. For this conduct he was summarily dismissed from his lord-lieutenancy. Scarcely less offence was given by the Duke of Hamilton, Lord-Lieutenant of the county of Lanark, who sent a subscription of fifty pounds to the committee for the relief of the Manchester sufferers, expressing, at the same time, his severe censure of the outrage committed on the 16th of August. Of course, the Ministerial party in town and country did all in their power to counteract this strong and general expression of disapprobation. In Scotland and the North of England the squirearchy got up associations for raising troops of yeomanry, as in direct approval of the savage conduct of the Manchester Yeomanry. In the immediate neighbourhood of the scene of outrage the conflict of opinion between the two parties ran high. Numbers of the Manchester Yeomanry were indicted for cutting and maiming in St. Peter's Field, with intent to kill; but these bills were thrown out by the grand jury at the Lancaster assizes. An inquest at Oldham, on the body of one of the men killed, was also the scene of a fierce and regular conflict for nine days, that was put an end to by an order from the Court of King's Bench. But even men who were accustomed to support Ministers generally were startled by their conduct on this occasion. Mr. Ward, afterwards Lord Dudley and Ward, in one of his letters written from Paris at the time, but not published till a later date, says:"What do reasonable people think of the Manchester business? I am inclined to suspect that the magistrates were in too great a hurry, and that their loyal zeal, and the nova gloria in armis tempted the yeomanry to too liberal a use of the sabrein short, that their conduct has given some colour of reason to the complaints and anger of the Jacobins. The approbation of Government was probably given as the supposed price of support from the Tories in that part of the country."

THREE:The other side of the city was only defended by the Seine, but the Allies, who had first to cross that river, feared that Buonaparte might come up and attack their rear while they were doing so. They determined, therefore, to attack the line of fortifications. The most lying proclamations were issued by the ex-King Joseph to assure the inhabitants that the bodies of the enemy who came in view were only stragglers who had managed to get past the army of the Emperor, who was dispersing the Allies most triumphantly. The forces in Pariseight thousand troops of the line and thirty thousand of the National Guardwere reviewed in front of the Tuileries on a Sunday, to impress the people with a sense of security; but on the morning of the 29th the Empress and her child quitted the palace, attended by a regiment of seven hundred men, and fled to Blois, carrying with her the crown jewels and much public treasure, and followed by nearly all the members of Government. The populationunlike their fathers, who stopped Marie Antoinette in her attempt to escapesuffered this departure with murmurs, but without any attempt to prevent it. When she was gone they began heartily to curse Buonaparte for the trouble and disgrace he had brought upon them. That very morning Joseph issued a most flaming proclamation, assuring the Parisians that the Emperor was at hand[82], and would annihilate the last traces of the audacious enemy. But already the assault had commenced, and the next day, the 30th of March, it was general all along the line. The Parisians fought bravely, especially the boys from the Polytechnic schools; and as the Allies had to attack stone walls and batteries, their slaughter was great. Joseph rode along the line to encourage them in this useless, because utterly hopeless, waste of life. The Allied monarchs had, before commencing the assault, issued a proclamation, promising that all life and property should be strictly protected if the city quietly opened its gates; and, in the midst of the storming, they sent in again, by a French prisoner, the same offer, adding that, should the city be carried by assault, no power on earth could prevent it from being sacked by the enraged soldiers, and probably destroyed. Yet Joseph did not give the order for capitulation till the whole line was in the hands of the Allies, except Montmartre. The Cossacks were already in the Faubourg St. Antoine, and bombs flying into the Chausse d'Antin. Then King Joseph, whose lying proclamation was still selling on the boulevards at a sou each, ordered Marmont to capitulate; and though he had vowed in his proclamation to stand by the Parisians to the last gasp, he then fled after the Empress to Blois. In this defence four thousand French were killed and wounded, and double that number of the Allies, as they had to face the towers and batteries crowded with soldiers and to fight their way up hill.
