TWO:He did no good, and on his way home was taken prisoner by the English and carried to England. There, amongst other French prisoners, he met the young Comte de Genlis, an officer in the navy who had distinguished himself at Pondicherry, been desperately wounded, and gained the cross of St. Louis. They became great friends, and M. de Genlis expressing great admiration for a miniature of Flicit which her father constantly wore, M. de Saint-Aubin poured into his ears the manifold perfections of his daughter, and read to him the letters he frequently received from her. When M. de Genlis soon afterwards was set free, he used all the means in his power to obtain the release of his friend, and, in the meanwhile, called upon Mme. de Saint-Aubin at Paris, bringing letters from M. de Saint-Aubin, who three weeks afterwards was set at liberty, and returned to France; but his affairs were in such a state that he was induced to give a bill which, when it fell due, he could not meet. Six hundred francs was all that was required to execute the payment, and Mme. de Saint-Aubin wrote to her half-sister, who had married a rich old man, M. de Montesson, asking her to give or lend her money. She refused to do so, and M. de Saint-Aubin was arrested and imprisoned. His wife and daughter spent every day with him for a fortnight, at the end of which, the money being paid, he was released. But his health seemed to decline, and soon afterwards he was seized with a fever which ended fatally, to the inexpressible grief of Flicit, who always laid his death at the door of Mme. de [365] Montesson, whether with justice or not it is impossible to say, though, at any rate, her refusal to help the sister who had been so shamefully treated, and who was in distress, sounds exceedingly discreditable.

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.
