TWO:Very early in the morning we met a many-coloured caravan of men, women, and children riding astride on asses, amid baskets and bundles. They were on their way to a wedding: they had stopped to rest for the last time; and alone, far from the merry, noisy group, a "bad woman" sat down on a stone. She was on the way to the same festival, and was allowed to travel with the[Pg 288] caravan for succour in case of need; but she was not permitted to join the party.

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:In the afternooncalm and almost coolI went to call on the Resident, who talked to me of India in the days of Dupleix, of its departed glory, and the poor old fort of Chandernagore, once impregnable and now demolished under the provisions of treaties; and as we walked on through the town, between gardens that look like the great parks of the French kings, all the past seemed to live again on this forgotten spot of earth, and every moment, in the silence of the purple dusk, I could have fancied that I saw in the avenues, under the tall ph?nix palms, the shades of powdered marquises in skirts with full farthingales, and of gallant knights of St. Louis; then from a far distance came the sound of a pianosome simple melody quavering in the air that was so full of memories.
  • Equipment costs can be reduced.
  • Operating costs can be reduced.
  • Maintenance costs can be reduced.
  • Any change in raw material and product can be easily addressed.
  • Large amounts can be treated in a small area.
  • Separation and cleaning are easy because of the simple structure.
  • Simplified control
  • This equipment can be operated in synchronization with external devices.
  • Alarm and interlock mechanism.
THREE:AGRAOne of the servants of the place, sitting in the shade of the arcade, was painting, after a strange method. He sprinkled powdered colour on the surface of some water in a tub, outlining the colour with black; then, with a feather, he massed and arranged the colours, taking some off and replacing it in infinitesimal quantities. Finally the result was a representation of Siva and Ourasi, robed in blue and violet, against a background of crude red. When they were quite finished he jerked the bowl, giving the figures a curtseying motion, and stood a little way off to contemplate the general effect;[Pg 158] and then, quite satisfied, stirred the whole thing up and began again, the same picture, with the same precise care.
