    摘要: Cantilever chemical vapor sensors that can be tailored to respond preferentially in frequency by controlling the location of deposition of an adsorbing layer. Cantilever chemical vapor sensor having a base, one or more legs and a tip are fabricated using a gold layer to promote deposition of a sorbing layer of a polymeric material in a desired location, and using a chromium layer to inhibit deposition of the sorbing layer in other locations. Sorbing layers having different glass temperatures Tg and their effects are described. The methods of making such cantilever chemical vapor sensors are described.

    摘要: A system for analyzing a gas mixture, including at least one chromatography column, a mechanism injecting the mixture into the column, and a mechanism detecting compound(s) forming the gas mixture, the detection mechanism including at least one detector of nanosensor type of an outlet of the column and a detector of nanosensor type in the column, capable of detecting passage of the compounds. It is then possible to determine the velocity of each of the compounds within the system.

    摘要: An eccentrically rotatable control valve has a seat ring containing two seating surfaces and a stationary sealing ring mounted on an inner wall of a valve chamber to form a port therein. Rolling movement of an eccentrically mounted plug of the valve from a partial to full line fluid tight sealing contact with one of the seating surfaces of the seat ring causes the seat ring to be simultaneously moved in a rocking manner and the other seating surface of the seat ring to be moved into fluid tight sealing engagement with the stationary sealing ring. The rockable seat ring construction provides a means by which the plug and its associated seat ring can center itself in a properly seated fluid tight position on the sealing ring in the event that the sealing ring is out of properly aligned seating surface engagement with the plug.
