    Inventor: Vittorio Prodi
  • Device for the separation of airborne particles into classes by grain size
    Patent number: 4704528
    Abstract: A device of improved type for the separation of airborne particles by grain size is described.The principle characteristic of the present invention lies in the fact that it comprises: a first base body in which is formed a first cavity on the edge of which rests a plate on which is deposited a filter; two second bodies, one inside the other, in such a way as to define between them an annular channel in which is ducted filtered air and communicating with the said first cavity through a second cylindrical cavity defined by the lower surface of a base wall of the said inner second body and the upper surface of the said filter; and an annular nozzle located in the said channel and operable to eject into it a quantity of particle-bearing air in such a way that the particles of dust present in this are deposited on the said filter.

  • Lung simulating aerosol sampler
    Patent number: 4092845
    Abstract: A simulator of the aerosol particle disposition in the human respiratory tract comprises a duct along which the following devices are included in the order: an air humidifier comprising a trunk with longitudinal partitions of blotted paper soaked with water, a cyclone, a vibrated bubbler comprising a cylindrical vertical vessel partially filled with water and provided with a pierced horizontal partition at a level lower than the water level within said vessel, a vacuum pump, a flowmeter. The air to be tested is passed through said duct for a predetermined time period and at a predetermined flow rate. Subsequent to said passage, physical, chemical, toxicological, radiometric analyses are carried out either on the water itself or on the solid therein contained or on both.
