摘要： A Fluorescence Particle Spectrometer (FPS) performs real-time measurement of the fluorescence spectra of aerosol particles in the size range 1-10 μm diameter. The FPS has a sufficiently high sample rate (estimated to be a few liters/min) to measure aerosol within buildings (from 1 up to 600 particle fluorescence spectra per minute) at practical rates. A virtual impactor first concentrates aerosol particles, which are then drawn under negative pressure through an aerodynamic focusing nozzle in the inlet of the instrument, through the sample region, providing further concentration. The rate of particle spectra measured by the FPS increases significantly when the particle inlet is within a few meters of some common sources of indoor biological particles.

摘要： An aerosol deflection system having a concentration zone expelling an air stream through a first detection zone, a second detection zone, and a deflection zone. The first detection zone activates the second detection zone based upon detection of a suspect aerosol of a pre-selected size. The second detection zone activates the deflection zone when the suspect aerosol of the pre-selected size has a predetermined light-induced-fluorescence signature. The deflection zone directs a pressure pulse at the suspect aerosol having the predetermined light-induced-fluorescence signature to deflect the suspect aerosol from the air stream.

摘要： A transmission device for a band saw includes mainly a transmission, which, connected axially with a motor, consists of a driving gear set, a driven gear set, an output gear set and a gear rod. The gear rod is connected with a gearing jaw engaged with the output gear set inside the transmission and having a pushing device able to push the output gear set forward or backward to engage with the driven gear set to rotate in different speeds. And, combined with a driving mechanism, various speeds can therefore be selected for the sawing band to work, depending on the properties of the material to be sawed, upgrading sawing quality and efficiency.

摘要： A chisel quickly adjusting and positioning device for a chiseling machine includes a plurality of separating members for adjusting a gap between a sleeve and the bottom of a machine body, and a chisel unit composed of a chisel and a drill fitting lengthwise in the chisel. After the drill is fitted in the chisel and then clamped in a drill chuck, the chisel unit is fitted in the sleeve. Then the separating members can be pivotally moved in or out of the gap between the sleeve and the bottom of the machine body, and then the sleeve is pushed up so that a gap between the chisel blade and the tip of the drill may be formed for quickly adjusting and positioning the chisel unit with the machine body.
