TWO:The large town lies along the bank of the Jellum; the houses are of wood, grey and satiny with old age, and almost all tottering to their end on the strand unprotected by an embankment. The windows are latticed with bent wood in fanciful designs. Large houses built of brick have thrown out covered balconies and verandahs, supported on tall piles in the water, and on brackets carved to represent monsters or flowering creepers.

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:An aggressive capital! Palaces of concrete and stucco washed with yellow stand cheek by jowl with commission agencies and hovels, and all without a suspicion of style, not even giving one the impression of a southern city. In the streets, thick with dust, an all-prevailing turmoil as of a fair is prolonged to the latest hours of night. Red uniforms and "young England" tourist suits ending their career in rags on half-breed cooliesa wearisome staleness and total effacement of local colour, worse than commonplace; and then, above all, a very strong and nauseating smell of lotus and tallow, with an after-gust of something peppery and acrid.Above Darjeelinga modern and fashionable health-resort, a town of villas, for the most part with corrugated iron roofshangs a dense mist, cutting off the horizon at a distance of a few miles; and through the dull substance of this fleece, at an impossible height, there was a reflectiona mirage, an illusion, a brighter gleam, a bluer shadow, which might be the top of a mountain; but so high up, so far away, and above all so transient, that it failed to fix itself on the memory, blotted out at once by the pallid wall that shut[Pg 147] in the scene. But at sunset one thickness of the haze melted away, unveiling, leagues on leagues away, a chain of giant mountains, not yet the snowy peaks, but bright-hued cliffs on which gold and purple mingled in symphonies before dying into violet, turning to blue in the moonlight; and the mists fell once morea shroud at our feet, an abyss of shadows, in which the tea-planters' lamps twinkled through the darkness.
