  • Patent number: 5381829
    Abstract: A fluid mixing device includes a housing having two inlets for two fluids to be mixed, a common outlet, and a cylindrical chamber connecting the inlets to the outlet. A valve member is disposed within the cylindrical chamber and includes a cylindrical wall formed with a slot extending for a part of the wall circumference. The housing inlets include slots extending transversely of the cylindrical chamber. The valve member is displaceable axially for moving its slot into or out of alignment with the inlet slots. It is also presettable angularly to permit presetting the proportion the valve member slot is coextensive with the inlet slots, and thereby the proportions of the inletted fluids to be included in the outlet mixture. Also described is a demand valve optionally usable with the fluid mixing device.

  • Patent number: 5333052
    Abstract: An inspection system for providing high contrast images of two materials of an article to be inspected is disclosed. Light with variable spectral range and large angular coverage is passed from the source through a polarizer, reflects from or is transmitted through the article to be inspected, passes through an analyzer and is detected by a sensor. A phase compensator is disposed either between the polarizer and the sample or the sample and the analyzer. Two of the three polarization optical components, that is, the polarizer, the compensator and the analyzer, are separately adjusted until the maximum contrast is found in the image. This enables high contrast imaging of surfaces of objects of similar optical reflectivity, (such as surfaces consisting of two similar specular materials, or surfaces partly covered with transparent films) which cannot be imaged using normal reflective image forming techniques.
