TWO:"Go along with your doctor," said Maitrank now, in great good humour. "If you will have the goodness to call a cab I will get back to my hotel."In working to regular scales, such as one-half, one-eighth, or one-sixteenth size, a good plan is to use a common rule, instead of a graduated scale. There is nothing more convenient for a mechanical draughtsman than to be able to readily resolve dimensions into various scales, and the use of a common rule for fractional scales trains the mind, so that computations come naturally, and after a time almost without effort. A plain T square, with a parallel blade fastened on the side of the head, [80] but not imbedded into it, is the best; in this way set squares can pass over the head of a T square in working at the edges of the drawing. It is strange that a draughting square should ever have been made in any other manner than this, and still more strange, that people will use squares that do not allow the set squares to pass over the heads and come near to the edge of the board.

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:The steam-engine is the most important, and in England and America best known among motive agents. The importance of steam contrasted with other sources of motive-power is due not so much to a diminished cost of power obtained in this way, but for the reason that the amount of power produced can be determined at will, and in most cases without reference to local conditions; the machinery can with fuel and water be transported from place to place, as in the case of locomotives which not only supply power for their own transit, but move besides vast loads of merchandise, or travel.That same Friday evening the women and children living in the Rue de la Station were told to leave their houses as the whole street was to be burned down. Everybody fled, but the design was not executed. The burgomaster and his son were taken prisoners, and brought to Tongres; later on the son was released; the Very Reverend the Dean was also arrested.
  • 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:Women and children had frequently been ill-treated in a most atrocious manner, aged and sick people were dragged out of the houses, and flung down in the street. This happened, for example, to an old man, who lay dying in his cellar. In spite of the supplications of his wife and two sons, he was flung on the cobbles, where he died soon. The sons were taken prisoners and sent away. His widow assists at present nursing other unfortunates at Professor Noyons' hospital.
