Sir John marched out of Edinburgh for the north on the very day that the standard of the Stuarts was erected in Glenfinnan, the 19th of August. On the following day he continued his route from Stirling, accompanied by one thousand five hundred foot, leaving, very properly, the dragoons behind him, as of no service in the mountains, nor capable of finding forage there. He then continued his march towards Fort Augustus, which he hoped to make the centre of his operations, and then to strike a sudden and annihilating blow on the handful of rebels. At Dalwhinnie he heard that the rebels now mustered six thousand, and that they meant to dispute the pass of Corriarrick, lying directly in the line of his march towards Fort Augustus. This Corriarrick had been made passable by one of General Wade's roads, constructed after the rebellion of 1715, to lay open the Highlands. The road wound up the mountain by seventeen zig-zags or traverses, and down the other side by others, called by the Highlanders the Devil's Staircase. Three hundred men were capable, much more three thousand, of stopping an army in such a situation, and Cope called a council of war. At length it was agreed that they should take a side route, and endeavour to reach Inverness and Fort George. The resolve was a fatal one, for it gave the appearance of a flight to the army, and left the road open to Stirling and the Lowlands.
But now Catherine of Russia had concluded her entanglements with Turkey. It was the August of 1791, and her eyes turned immediately on Poland, and she pretended to take great offence and alarm at the new Constitution, as full of French and Revolutionary principles, and therefore intolerable to any neighbouring state. She began to negotiate with Sweden, and Prussia, and Austria, to co-operate with her in her design against Poland. Prussia was easily led to adopt her ideas, for the king was like herself, greedy of his neighbour's dominions, and had been repulsed by the Poles in grasping at Thorn and Dantzic. Leopold of Austria was, by his connection with the royal party of France, through his sister, naturally ready to put down any influence from the French Revolution in a neighbouring country; but he was indisposed to war, and too just and moderate for aggression. His death, on the 1st of March, 1792, removed this obstacle, and Francis, his successor, was found to be more accessible to the Czarina's selfish arguments. Russia, Prussia, and Austria were all agreed on the plunder of Poland, whilst they still preserved the most hypocritical appearance of caring only for its unity and national interests. As for Gustavus III., of Sweden, brave and honest as he was, he was of such chivalrous and, to a certain degree, insane character, that he was easily led on by the artful Empress of Russia to lend himself to her designs, without being aware of them. He had declared himself the knight of Marie Antoinette, and had sworn to rescue her. He was avaricious of military glory, and, like his predecessor, Charles XII., he was desirous only of conducting some great and brilliant enterprise. He desired to lead an army against the French, now bursting out under the Revolutionary general, Custine, on Germany, and, joining with the army of the Emigrants, eighteen thousand in number, to beat back the Democratic general, to march into France, and restore the throne of Louis and Marie Antoinette. But he had no money; the Empress of Russia, who wished him employed at a distance, and especially in keeping back the French Democrats, whilst she carved up Poland, offered him both money and arms. But the Empress was relieved of the high-minded Gustavus in a manner which she had by no means contemplated. He fell, on the 16th of March, in his own capital, by the hand of an assassin called Ankarstr?m.
Hydrocyclone (liquid cyclone)
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.
