摘要： An impactor assembly comprises a base for supporting a plurality of cups that form impactor plates, and a nozzle above each of the cups through which a flow passes for classification. The cover is removable, and a test cover can be put into position for mounting in place and providing outlets connectable to pressure sensor for determining pressure drop across the nozzle plates at each impactor stage. The cover also is designed to be easily washed by having no blind cavities or moving parts on the cover, and the latch and other hinge assemblies are all supported on the base. The flow enters and exits the impactor without having external connections on the cover.

摘要： A bailer having multiple check valves to minimize leakage of sample fluid from the bailer. A primary check valve assembly including a ball and a seat are disposed at a lower end of the bailer. At least one auxiliary check valve assembly is positioned above the primary check valve assembly. When a first auxiliary check valve closes, the hydrostatic pressure applied to the primary check valve is reduced significantly and leakage through the primary check valve is reduced. When a second auxiliary check valve closes, the hydrostatic pressure applied to the first auxiliary check valve is reduced and the same benefits are obtained for the first auxiliary check valve. Particulate matter is collected in an annular trough formed in the primary check valve assembly and in pockets that form a part of each auxiliary check valve assembly.

摘要： The extraction of intact, representative fluid samples in well-defined depths, such as from wells sunk into the ground, has until now been very difficult, and in many cases impossible to perform. A method is provided as well as a sample extractor for the extraction of intact fluid samples, in particular from a well (26) sunk into the ground, by submersion of a compressible hollow flexible body (22) fitted in a supporting device which, subsequent to submersion to the sample extraction depth, is acted upon to effect liquid entry through an inlet. In particular, hollow flexible body (22) is held in the support device in the form of a pressure vessel (2) and fully compressed by pressurized gas inside the pressure vessel, whereupon the pressure vessel is caused to change in such a way that a surrounding fluid seeps into the hollow flexible body (22), whereupon the vessel (2) with the body (22) containing the fluid sample is hoisted out of the well (26).

摘要： An air-tight bailer is filled completely and closed at its open upper end with a flat cap so that no ambient air is trapped in the bailer. A mounting member to which a rope is secured for lowering and lifting the bailer is recessed with respect to the open upper end of the bailer so that it does not interfere with the cap. A disc-shaped protuberance formed on the bottom of the cap fills the recess. An annular groove around the recess receives the rim of the open upper end to enhance an air-tight seal between the cap and the open upper end. In a first embodiment, the bailer is emptied by piercing a thin membrane formed in the cap with a spout device having a trailing end in fluid communication with a container. A second embodiment eliminates the membrane and the spout device.

摘要： A no purge sampler for collecting fluid samples includes a flexible tube having a sealed first end and a second end, the tube defining an interior cavity, a buoyancy-compensating ballast compartment secured to the tube, and a check valve disposed at the second end of the tube. To collect fluid samples, the no purge sampler is lowered into the fluid to be sampled. The buoyancy-compensating ballast compartment is filled with an appropriate ballast to allow the sampler to sink to a desired level. Once the sampler reaches the desired depth, the sampler is moved up and down to pump water into the collapsed tube. The check valve is opened each time the sampler is pulled upwards allowing fluid to enter the interior cavity. The up and down motion is repeated until the interior cavity of the tube is filled with fluid. Once the interior cavity is filled, the pressure of the fluid in the tube causes the check valve to close, thereby preventing additional fluid from entering the interior cavity. The sampler is then pulled out of the fluid without losing any of the fluid in the interior cavity of the tube or the sample contaminated with any extraneous fluid.

摘要： An apparatus is provided for extracting cross-sectional samples of bulk material from a moving belt conveyor with a rotating sample cutter. The sample cutter is driven around a circular sampling path by a pair of double-acting pneumatic cylinders that are connected to angularly offset crank throws. Fluid flow in and out of each pneumatic cylinder pressure chamber is independently regulated as a function of the respective cylinder rod position and direction of movement whereby both chambers may be simultaneously open to the pressure supply or to the atmospheric vent for a brief rotational arc.

摘要： A bulk material sampler comprising an elongated body having a first axial bore and an interior wall, a handle having a second axial bore and a finger grip, and a shaft assembly axially supported. inside the first and second bores. The bottom end of the handle is connected to the top end of the body. The shaft assembly comprises a tip at the shaft assembly bottom end and a button at the shaft assembly top end. The button is adapted to protrude from the handle top end. The shaft assembly is axially moveable between an actuated position in which the button is maximally depressed within the handle, and a resting position in which the button maximally protrudes from the handle. The sampler further comprises means for biasing the shaft in the resting position, and a sample collection cavity defined by a portion of the tip and a portion of the body interior wall. The tip may be removable from the shaft assembly. A plurality of tips having different configurations tailored for sampling different bulk materials are claimed, as are methods for taking a sample using the sampler.
