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.A port crowded with steamers taking in coal, and very light barks high out of the water, kept in equilibrium by parallel outriggers at the ends of two flexible spars. These crank boats, made of[Pg 124] planks that scarcely overlap, were piled with luggage, and the boatmen jostle and turn and skim close under the fast-steaming transatlantic liners, amid a bewildering babel of shouts and oaths, under a sun hot enough to melt lead.

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:BOMBAYA wide open space covered with rubbish heaps was to be seen where the sepoys' barracks had been, and where from the first the men had died of the plague by hundreds. In one garden, a bungalow where a[Pg 303] man had just died was being burnt downstill burning. A party of police were encouraging the fire, and a cordon of native soldiers kept everybody else off.
  • 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:The country was nowhere deserted. Labourers in the rice-fields were transplanting the young seedlings or watering the taller growth that waved in delicate transparent verdure. Or again, there were the watchers perched on their platforms in the middle of the fields; fishermen pushing little nets before them, fastened to triangular frames, or grubbing in the mud in search of shell-fishsmall freshwater mussels, which they carried away in clay jars of Etruscan form. A motley crowd, with animated and graceful gesticulations; the women red or white figures in fluttering sarees, with flowers in their hair, and a few glittering bangles on their arms; the children quite naked, with bead necklaces and queer charms of lead or wood in their ears or their nose; the men slender and active, wearing light-coloured turbans made of yards on yards of twisted muslin, their brown skin hidden only by the langouti or loin-cloth.At the station pilgrims again, bewildered, shouting, rushing about in search of their lost luggage. One group presently emerged from the crowd, led by a man bareheaded, who rang a big bell with great gesticulations, his arms in the air, and the whole party marched off towards the temples in silent and orderly procession.
