    摘要: A portable aerosol dust spectrometer has an inlet section with a sampler entry having an entry efficiency for airborne dust approximately to that of the human head during inhalation, a clean-up stage to remove particles above 15 .mu.m and a main collection stage which is a cascade impactor. The cascade impactor classifies particles of dust and collects fractions onto a number of collection surfaces. A pump draws air or gas through the apparatus. The apparatus samples air in a similar way to the human body and yields fractions of dust for further study.

    摘要: Method and apparatus are disclosed for coating substrates with a film polymer based on p-xylylene by vapor-phase polymerization. The apparatus monitors the monomer vapor pressure after pyrolization of the cyclic di-p-xylylene dimer, compares the measured pressure to a predetermined pressure needed to effect a completed vapor-phase polymerization reaction, and adjusts the temperature of vaporization in response to variations between measured pressure and the predetermined pressure.

    摘要: Method and apparatus are disclosed for coating substrates with a film polymer based on p-xylylene by vapor-shaped polymerization. The apparatus monitors the monomer vapor pressure after pyrolization of the cyclic di-p-xylylene dimer, compares the measured pressure to a predetermined pressure needed to effect a completed vapor-phase polymerization reaction, and adjusts the temperature of vaporization in response to variations between measured pressure and the predetermined pressure.

    摘要: An apparatus for separating fine dust particles from coarse dust particles, such as are present in hot filling powders for pit furnaces for the production of electrodes by aluminium fusion electrolysis, comprises a first separator with an adjustable separation gap, arranged inside a bin on an intermediate bottom, which is preferably slanted, dividing the bin into an upper chamber and a lower chamber. The air flow is sustained by a fan connected with its discharge side to the lower chamber. The suction side of the fan is connected to the upper chamber through a further separator for the fine particles and through respective pipes. Preferably the suction return path through the pipes and the further separator leads through a further collector.

    摘要: In a vertical classifier, a high efficiency of separation is achieved by recirculating a portion of the main fluid stream within the classifier so as to create a horizontal vortex whereby larger particles are prevented from passing with the fine fraction; incoming fluid serves to carry fines from such recirculated portion of the fluid stream.
