Class Information
Number: 356/426
Name: Optics: measuring and testing > By inspection with agitation or rotation
Description: Subject matter wherein there is apparatus to inspect articles of manufacture, including containers and contained fluids for foreign particles such as dirt, and which includes means to support and rotate, agitate, or otherwise move the containers or the fluid contents to cause motion of the article or of the particles in the fluid contents as part of the test procedure and not as a condition of transporting the article to and from the test location; and means to illuminate the article so that the illumination may be transmitted through the articles, containers or contained fluid or reflected from the article or container, or transmitted around portions of an article for the purpose of testing for defects, blemishes, flaws or any other type of imperfection.
