An outer needle valve (104) is reciprocally mounted in the outer cavity (216) and has a seat portion (224) arranged to abut the needle valve seat (218) when the outer needle valve (104) is seated or closed. A first ledge (502) formed on the seat portion (224) of the outer needle valve (104) sealably contacts the needle valve seat (218) along a first line contact seal (220) and a second ledge (508) formed on the seat portion (224) of the outer needle valve (104) sealably contacts the needle valve seat (218) along a second line contact seal (222).

  • Patent number: 8469295
    Abstract: An explosive and narcotics detection system detects the presence of trace particles of those materials that are adhering to surfaces. In order to detect such particles, it is necessary to first dislodge or release them from the surface, next to transport them to the detection instrument, and last to accumulate them on or in a particle collection device associated with the instrument. Narcotics and explosive particles are often bound tenaciously to the surface, and simple techniques, such as blowing air, will either remove only the largest particles or none at all. A nozzle to release particles of narcotics and explosives employs a coaxial configuration that permits particle release at an increased distance from the nozzle compared to existing devices.

  • Patent number: 8348174
    Abstract: Systems and methods for energy-saving and water-saving devices are disclosed. In some embodiments, a head assembly is coupled to receive a liquid flow from a liquid supply and a gas flow from a gas supply, wherein the head assembly defines a mixing region configured to receive the liquid flow and the gas flow, and a dispensing portion configured to receive a combined flow from the mixing region. In some implementations, a spray nozzle may sprayably introduce the liquid flow into the mixing region. In other implementations, a plurality of curtain flows may be drawn through apertures into the dispensing portion by the combined flow. In still other implementations, a portion of the combined flow dispensed by the head assembly may be recaptured into the gas flow.

  • Patent number: 8327643
    Abstract: A main swirler of a triple annular configuration that is partitioned by a pre-filmer and a separator is installed in an inlet port of a main air flow channel. The vicinity of the inner wall of the main air flow channel provided with a main fuel injection port is bulged radially outward from the innermost surface (innermost surface of a small swirler) of a main swirler. Further, a distance from the main fuel injection port and the pre-filmer is set such that an effective opening area between the pre-filmer and “the inner wall of the main air flow channel provided with the main fuel injection port” is equal to an effective opening area of the small swirler. The swirling directions of the swirlers of the main swirler are “clockwise”-“counter-clockwise”-“clockwise” respectively along the radial outward direction when the swirling direction of the innermost swirler is taken as “clockwise”.

  • Patent number: 8302880
    Abstract: A method of creating substantially monodisperse droplets comprising supplying a first fluid (1) and a second immiscible fluid (2) within a set of channels, the second fluid surrounding the first fluid and filling the channels to form a composite jet. The composite jet passes through an entrance channel (4) into a wider cavity (3), where the first fluid breaks into droplets (5), the resulting composite of droplets of the first fluid within the second fluid passing through an exit channel (6). The cross sectional area of the exit channel perpendicular to the flow is smaller than the cross sectional area of the cavity and the passage of a droplet of the first fluid out of the cavity via the exit perturbs the composite flow field within the cavity such that the incoming jet of the first fluid is perturbed.

  • Patent number: 8297530
    Abstract: A spray nozzle assembly that utilizes ultrasonic atomization techniques to atomize a liquid into a cloud of small or fine droplets is disclosed. The nozzle assembly also can use various air or gas atomizing technologies to propel the generally directionless droplet cloud toward a surface or substrate to be coated. The propelled droplet cloud may at this state have a conical or cone-shaped spray pattern. Additional air or gas atomizing technologies can be utilized to shape the propelled droplet cloud into a flattened fan-shaped spray pattern that can be usable in various industrial applications. The shape of the spray pattern and the distribution of droplets within the pattern can be adjusted by manipulation of the gas pressure used in gas atomization.

    Abstract: A device is disclosed that uses a flow-control methodology to control sprays at very high precision and frequency. The device is based on an enhanced Coanda effect. The control flow is selectively applied to the region in which we desire the jet to vector and control the profile (width) of the jet. The control flow is introduced through multiple control flow ports surrounding the primary nozzle and adjacent to the Coanda surface. By selectively opening and closing different control flow ports the motion and profile of the jet can be controlled.

  • Patent number: 8292615
    Abstract: A method for burning gas in a burner, including leading the gas through an inner fuel tube and introduction of combustion air through an annular space surrounding the inner fuel tube. This space forms of an outer tube terminated by a conically converging section, wherein the end of the inner fuel tube forms a burner head. The major part of the primary gas is introduced into the upstream end of the burner head, to go into the combustion air that flows past the burner head, whereas a smaller part of a secondary gas is introduced into the free end of the burner head and into the constricted part of the annular channel that surrounds the burner head. The gas flow is accelerated past the burner head due to the reducing cross section and is burned downstream in relation to the burning head.

  • Patent number: 8141796
    Abstract: An improved nozzle and iodine injector system for use in a COIL are disclosed. The improved nozzle is a two-dimensional, minimum length nozzle with a curved sonic line. The iodine injection system utilizes a series of slender struts for iodine injection into the oxygen stream through a series of small orifices that are located along the base of each strut. The struts are located within the nozzle such that the need for a diluent gas for the iodine is reduced. The use of the nozzle and iodine injection system, particularly when combined with the SOG disclosed in U.S. patent application Ser. No. 10/453,148, have the potential for yielding a highly efficient, high power, optically superior COIL device that is compact, scalable, can operate in space, and has good pressure recovery potential.
