摘要： An air-driven microfluid control device and its method are disclosed. The control device contains an air source, a first inlet, a second inlet, a narrow sector, and an outlet. The air source is connected two the two inlets to produce an airflow. The first inlet connects to the narrow sector, which then connects to the outlet. The air flows through the first inlet and the narrow sector and exits via the outlet. A fluid tunnel connects to the narrows sideways. The second inlet connects to the fluid tunnel so that the air entering the second inlet flows into the fluid tunnel. Through the interaction between the two inlets, pushing and pulling forces can be produced to control the fluid inside the fluid tunnel.

摘要： A chip sampling device comprising a sampling probe including an outer rotatable tube having an inner tube positioned therein. The upper end of the inner tube is in communication with a source of vacuum so that chips will be drawn into the lower end of the inner tube. The lower end of the inner tube is provided with serrations provided at the lower end thereof while the lower end of the outer tube is provided with serrations and inwardly extending fingers. The rotation of the outer tube and the action of the various serrations and fingers prevents the chips from plugging the lower end of the outer tube or from plugging the lower end of the inner tube.

摘要： A conduit extends from a reservoir through a sampling station and back to the reservoir in a closed loop. A jet ejector in the conduit establishes suction for withdrawing liquid from the reservoir. The conduit has a self-healing septum therein upstream of the jet ejector for receiving one end of a double-ended cannula, the other end of which is received in a serum bottle for sample collection. Gas is introduced into the conduit at a gas bleed between the sample collection bottle and the reservoir. The jet ejector evacuates gas from the conduit and the bottle and aspirates a column of liquid from the reservoir at a high rate. When the withdrawn liquid reaches the jet ejector the rate of flow therethrough reduces substantially and the gas bleed increases the pressure in the conduit for driving liquid into the sample bottle, the gas bleed forming a column of gas behind the withdrawn liquid column and interrupting the withdrawal of liquid from the reservoir. In the case of hazardous and toxic liquids, the sample bottle and the jet ejector may be isolated from the reservoir and may be further isolated from a control station containing remote manipulation means for the sample bottle and control valves for the jet ejector and gas bleed.

摘要： A method for generating an aerosol powder from a melt includes an atomization die having an orifice through which the melt passes to create the powder. In a preferred embodiment, the orifice has a dimension less than 5 millimeters, and may include a heater to prevent freeze-off. The die may be included in a high-temperature probe suitable for immersion on the melt, so that accumulated accretions of powder on the walls of the probe may be melted off by heating the probe.

摘要： A pneumatic sampler for use in collecting a sample of xerographic toner from a mass of such toner. A positive-pressure air source is connected to atmosphere through a venturi so as to produce a negative-pressure source. The positive-pressure source is also adapted to be connected through a first conduit to the toner mass. Positive-pressure airflow through this first conduit both purges the first conduit of residual toner and fluidizes at least a portion of the toner mass. A toner sample container is adapted to be simultaneously connected through a second conduit to the venturi. The resulting negative-pressure airflow through the second conduit evacuates the container. Negative-pressure induced airflow also purges the second conduit of residual toner. The container is connected to the toner mass through the series-connected and now-purged first and second conduits, and the negative-pressure within the container produces flow of toner from the toner mass to the container.

摘要： A device for taking a representative sample from a large volume of liquid in storage is disclosed. The device comprises a sealable sample container with fittings to facilitate attachment to the storage vessel to be sampled and a connected source of pressure controllable by valve means to cause movement of sampled liquid in and out of the sealed container. A filter unit connected to the sample container provides a trap for liquid or vapor that may be purged from the sample container as the sample is taken. The sample container has a control for providing automatic shutoff of sample flow when the sample container is filled. In one embodiment of the invention, source-pressure is utilized to create a suction for drawing liquid to be sampled into the sample container, and in a second embodiment, the source-pressure is used to purge the sample liner and its fittings prior to allowing the storage vessel pressure to force liquid into the sample container. The invention makes possible the taking of large-volume liquid samples without an explosion hazard and without exposing the operator to the liquid directly or otherwise releasing the chemical to the atmosphere.
