096413000 | WITH SAMPLING MEANS | 8 |
20080229930 | PARTICLE COLLECTION APPARATUS AND METHOD - A particle collector comprises a housing defining an enclosed chamber. An inlet opening in the housing provides fluid communication between a source of gas and particles and the chamber and an outlet opening provides fluid communication between the chamber and the exterior of the housing. The outlet opening is connected to a pump for drawing gas and particles through the housing from the inlet opening to the outlet opening. A collecting member having an adhesive on at least a portion of the surface is disposed in the chamber between the inlet opening and the outlet opening. The adhesive surface of the collecting member is positioned adjacent to the inlet opening. When gas and particles are drawn through the housing, the inlet opening directs a stream of gas and particles at the surface of the collecting member. Particles having an aerodynamic equivalent diameter of less than about 2.5 μm are captured. | 09-25-2008 |
20100050879 | FILTER ARRANGEMENT - A filter arrangement for removing impurities from a fluid is disclosed, the filter arrangement ( | 03-04-2010 |
20110232498 | Omnidirectional Aerosol Sampling Intake - An aerosol sampling intake configured to exclude particles generally greater than 20 microns AD and capture particles of less than about 10 microns AD with high efficiency, independent of weather conditions, through which air is sampled by suction. The intake combines an omnidirectional horizontal segment with diffuser and elbow, the elbow transitioning flow to a vertical segment, the vertical segment with overhanging lip, the centrifugal impactor for self-cleaning operation, thus relieving the dual problems of re-entrainment of particles bouncing from the impactor surface and fouling by particles sticking to the impactor surface. The device is adapted for use on moving vehicles, for sampling at increased windspeeds, or for sampling in rain. | 09-29-2011 |
20110290120 | METHOD AND APPARATUS FOR IN-SITU TESTING OF FILTRATION SYSTEMS - Embodiments of the invention generally provide an apparatus and method for certifying a filter in a containment system without decontaminating the containment system prior to certification. The apparatus generally comprises a valve assembly selectable between at least three operational states. A first state prevents flow from prevents flow through a port of a housing. A second state fluidly couples the port to test equipment necessary to test a filter disposed within the housing. A third state seals the port but fluidly couples the test equipment to a decontamination system. | 12-01-2011 |
20120060696 | AIR FILTERING SYSTEM CAPABLE OF ENHANCING INSPECTION CONVENIENCE - The present invention relates to an air filtering system capable of enhancing inspection convenience, which is disposed in the ceiling and comprises a housing, a filter, a first sampling tube, and a second sampling tube. On both ends of the housing, an intake and an outtake are disposed opposite to each other. The filter is disposed in the housing, and has an intake surface and an outtake surface opposite to each other. The filter divides the inner space of the housing into a first sampling zone and a second sampling zone. A first end of the first sampling tube is fixed on the housing, and communicates with the first sampling zone. Likewise, a first end of the second sampling tube is fixed on the housing, and communicates with the second sampling zone. Besides, a second end of the first sampling tube and a second end of the second sampling tube are both fixed on the wall. Thereby, the inspection convenience for the inspection staffs can be enhanced. | 03-15-2012 |
20130213236 | FAILURE DETECTING APPARATUS FOR PARTICULATE FILTER - An object of the present invention is to detect any breakdown or failure of a particulate filter more appropriately. A failure detecting apparatus for detecting failure of a particulate filter according to the present invention comprises an acquiring section which acquires an amount of PM contained in an exhaust gas allowed to outflow from the particulate filter; a regeneration process executing section which executes a filter regeneration process for oxidizing and removing PM deposited in the particulate filter; and a failure judging section which judges that the particulate filter is in the failure state if a decreased amount of the amount of PM contained in the exhaust gas acquired by the acquiring section, during a predetermined period of time as started from a point in time at which the execution of the filter regeneration process performed by the regeneration process executing section is completed, is not equal to or larger than a predetermined reference amount. | 08-22-2013 |
20130247768 | APPARATUS, SYSTEMS, AND METHODS FOR SAMPLING AND CONDITIONING A FLUID - A system of sampling a fluid comprises a fluid separator having a central axis. The fluid separator includes an insulating sleeve. In addition the fluid separator includes a separator assembly coaxially disposed within the sleeve. Further, the fluid separator includes an annulus radially disposed between the sleeve and the separator assembly. The separator assembly includes a conduit, a support rod coaxially disposed within the conduit, and a plurality of separator members coupled to the support rod within the conduit. | 09-26-2013 |
20140338540 | EXHAUST GAS FLOWMETER AND EXHAUST GAS ANALYZING SYSTEM - The present invention is adapted to be provided with: a first sampling line for sampling raw exhaust gas; a first concentration measuring part that measures the concentration of the predetermined target component contained in the raw exhaust gas; a second sampling line for sampling diluted exhaust gas; a second concentration measuring part that measures the concentration of the target component contained in the diluted exhaust gas; and an arithmetic unit that, with use of first measured concentration, second measured concentration, and a diluted exhaust gas flow rate, calculates a raw exhaust gas flow rate, wherein in a state where the first sampling line and the first concentration measuring part are heated, the first concentration measuring part measures the concentration of the target component contained in the raw exhaust gas. | 11-20-2014 |
