  • Patent number: 9067219
    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: 6234002
    Abstract: Automated apparatus and method to aid in the servicing of fuel injectors is adapted to be selectively operated in a test mode or a cleaning mode. The test mode senses flow rate through the injector and current draw of the injector solenoid, and provides the operator with visual indication and a printed record of the data. The cleaning mode begins with a testing sequence to record baseline flow and current draw data, cycles through predetermined cleaning steps including flowing a cleaning agent through the injector, checks the flow rate and current draw of the injector during and after the cleaning cycle, and repeats the testing sequence. This testing-cleaning cycle may be repeated until either the injector meets predefined performance criteria or until a pre-selected limit has been reached.

  • Patent number: 6037010
    Abstract: In a method of cleaning a paint application system when switching between two different types or colors of paint, at least a predominant portion of the first paint (35) remaining in a paint line (3) is caused to flow back into its paint supply container (5). Then the entire paint line is flushed out using a flushing medium, before supplying the second paint through the paint line. In this manner, the paint remaining in the painting system at the end of a painting cycle is not wasted, but rather is saved to later be reused. A paint application apparatus includes a paint supply switching device (4), at least two paint supply containers (5 to 8), a paint spray nozzle (2), and a paint line (3) connecting the color switching device (4) to the spray nozzle (2). Two receiver stations (28) and (31) are interposed in the paint line (3), and a shuttle element in the form of a pipe cleaner swab (29) is arranged in the paint line (3) so as to be able to shuttle back and forth between the two receiver stations.

  • Patent number: 5756155
    Abstract: The invention provides a combination of a nozzle and a vacuum hood. The vacuum hood has a chamber that surrounds the tip of the nozzle and removes residue from the tip by a vacuum which flows in the chamber past the nozzle tip. This vacuum catches and removes residue from the nozzle tip and prevents the reside from interfering with the spraying action or dripping down. The method of the instant invention provides for dispensing a fluid from a nozzle without dripping fluid from the nozzle having a vacuum hood. The method comprises: (a) dispensing a fluid on a rotating semiconductor wafer through a nozzle over the wafer; (b) terminating the fluid flow through the nozzle; (c) creating an upward flow of gas about the dispensing nozzle when the flow of fluid through the nozzle is terminated; (d) capturing any fluid residue from the nozzle in the upward flow of gas; (e) removing the wafer and positioning another wafer; and (f) terminating the upward flow of gas; and repeating the process of steps (a) through (f).
