BCF/RCC/gm 15555 INSPECTING AND SORTING OF GLASS CONTAINERS Abstract of the Disclosure A method and apparatus for inspecting and sorting transparent containers such as glass containers having defects in the container sidewalls, and for distinguishing between commercially acceptable and unacceptable defects on the basis of defect type and size. A light source is positioned to direct diffused illumination through the sidewall of a container under inspection as the container is rotated about its central axis with the intensity of the illumination varying across the light source transversely of such axis as a pre- determined function of transverse position. In specific dis- closed embodiments of the invention, the light intensity is filtered across the source to provide transversely spaced outer regions of uniform intensities, either equal or unequal, and an intermediate region of either uniform intensity different from that in the outer regions or transversely varying intensity. A camera which includes a plurality of light sensitive elements disposed in a linear array parallel to the axis of container rotation is positioned to receive light energy transmitted through the container sidewall. Electronics monitor the camera light elements during container rotation, identifies defects as a function of differences in light detected by the camera elements at adjacent increments of container rotation, and generates signals to distinguish and sort defective containers from commercially acceptable containers. A conveyor sequentially presents containers for inspection and includes separate selec- table exit paths for acceptable and unacceptable containers. --o-- i.
