TWO:Far away, at the end of the bazaar, in a street where no one passes, are the shoemakers' booths littered with leather parings; old cases or petroleum tins serve as seats. Among the workmen swarm children in rags, pelting each other with slippers.Above the throne, in the white marble wall, is a round hole, the mark of a cannon-ball at the time of the Mutiny. Out of this came a parrot, gravely perching to scratch its poll; then, alarmed at seeing us so close, it retired into its hole again.

Hydrocyclone (liquid cyclone)01

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:A tall wide gate beyond the bridge opens into the ferocious fortress of Hyderabad.On the shore, on the steps in front of the temples and round the holy images, in short, everywhere on this day, red powder was sprinkled to inaugurate[Pg 179] the month just beginning; a beggar, to secure the favour of the gods, had smeared his head and hands with it.
  • 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 the spacious harbour, where a whole fleet of steamships lies at anchor, a swarm of decked boats are moving about, sober in colour, with the bows raised very high in a long peak, and immense narrow sails crossed like a pair of scissors, and resembling a seagull's wings.Then, under a portico in front of us, a man began to undress. He threw off his dhoti and his sarong, keeping on his loin-cloth only. With outstretched arms he placed a heavy copper pot full of water on the ground, took it up between[Pg 171] his teeth, and without using his hands tilted his head back till the water poured all over him in a shower, which splashed up from the pavement, sprinkling the spectators in the front row. Next he tied his dhoti round the jar, which he refilled, and fastened the end to his long hair. Then, simply by turning his head, he spun the heavy pot round him. It looked as if it must pull his head off, but he flung it faster and faster till he presently stopped.
