TWO:When I went away home to the fort, where I was living with my friend Lieutenant F, the sentinel's challenge, the tall grey walls casting sharp shadows on the courtyard silvered with moonlight, and another sentry's cry; and still, in contrast with the cheerful evening, I could remember nothing but the tonga post-horsea thing so frequent in this land of fanatics, so common that no one gives it more than a passing thought.

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:
  • 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:In one brilliantly-lighted hall, priests, dressed in long yellow dalmatics, were adoring idols, elephants, Anantas; and from an enormous gold lotus sprang the Mandeel, rising through the dome, its tip standing in the outer air to bear the white flag that is hoisted on high festivals. At the entrance to this shrine parrots in cages suddenly set up a hostile outcry as I passed them, and were only pacified by the coming of a priest, who gave them some food. The clatter, however, had attracted other Brahmins; one of them desired me to leave, "and[Pg 117] at once." I declined to obey, so he sent for the elephant who does duty as police, to turn me out.At another station, a man, standing on the carriage step, held out a broad sheet to a servant, the two ends falling to the ground. Then a lady stepped out, hid herself under the stuff, which wrapped her from head to foot, and walked along the platform with a woman-servant. She was the wife of some superior clerk, not rich enough to have a palankin, but of too high caste to uncover her facea white bundle tottering along the platform. One of her antelope-skin slippers came off; for a second a tiny foot was put out with silver anklets. The woman put her mistress's shoe on again, and then both went to the waiting-room reserved for ladies.
