  • Patent number: 6032876
    Abstract: The invention relates to an apparatus for forming liquid droplets, such as a micro nebulizer, useful for preparing samples for subsequent analysis via MS, AA, ICP, CE/MS, and similar analytical systems. The apparatus has a mechanically stabilized inner microtube or needle, thereby ensuring controllably uniform droplet size. The mechanical stabilization is provided by securing the inner microtube or needle, such as by narrowing the inner diameter of the outer microtube or otherwise narrowing the annular intermediate space between the inner and outer microtubes for a predetermined length. Thus, the inner microtube is secured in a centered or otherwise predetermined fixed radial position, with minimum perturbation of the fluid flow. Further, a tip, when coupled with the exit end of the outer microtube, provides a region in which the sheath fluid flow in the outer microtube stabilizes prior to both exiting the tip and colliding with the liquid analyte exiting the inner microtube.

  • Patent number: 5996912
    Abstract: The injector nozzle includes a cylindrical needle which is axially reciprocated by an armature assembly. The needle has a needle tip terminating in a flat end surface with a spherical transition surface between the flat end surface and the side walls of the needle. Depending upon the diameter of the needle and the included angle of the valve seat, the diameter of the flat end surface may be less than the diameter of the orifice through the valve seat. The circular edge defined between the flat end surface and the spherical transition surface defines a location where the liquid fuel and air consistently separate from the needle in the valve-open condition whereby variations in the spray cone angle and the flow rate are minimized during steady-state and transient operating conditions.

  • Patent number: 5961045
    Abstract: A control valve, preferably for use with a fuel injector, includes a valve body defining an inlet passage separated from an outlet passage by a valve seat. A solenoid is attached to the valve body, and includes a coil and an armature. A portion of the armature is a permanent magnet. The polarity of the permanent magnet is oriented such that the armature is pushed away from the coil when the solenoid is energized. A valve member is positioned in the valve body and attached to the armature. The valve member is moveable between an open position in which the inlet passage is open to the outlet passage, and a closed position in which the inlet passage is closed to the outlet passage.

  • Patent number: 5950866
    Abstract: Method and apparatus for preparing and dispensing a cool beverage and for transporting ice. The apparatus utilizes a heat exchanger for directly contacting water and ice to produce cooled heat exchanger water in the heat exchanger from the water and ice and an outflow of the cooled heat exchanger water. A beverage concentrate flows through a beverage concentrate conduit that is in thermal contact with ice. The beverage concentrate is thus cooled by indirectly contacting the ice to produce an outflow of cooled beverage concentrate. A proportioner and mixer receive the outflow of cooled heat exchanger water and the outflow of cooled beverage concentrate, and proportion and mix the outflows to produce a cool, proportioned, mixed beverage, which is dispensed from a dispensing valve.

  • Patent number: 5938118
    Abstract: An aerosol dispensing apparatus comprises a housing which includes a top l having a sharp edged orifice and a speaker assembly mounted on a bottom portion of the housing. A sawtooth waveform generator generates and then provides a sawtooth waveform signal which includes a jitter component to the speaker assembly which drives a flexible diaphragm resulting in a reciprocating motion of the flexible diaphragm. The ramp portion of the sawtooth waveform signal retracts the flexible diaphragm in a rearward direction, while the approximately vertical portion of the signal causes an abrupt forward movement of the flexible diaphragm. The inner portion of the housing forms a chamber which contains a medication. The jitter component of the sawtooth waveform signal fluidizes the medication suspending the medication in air within the chamber to form a vaporized medication.
