Abstract: The present Specification describes an apparatus for the inspection of translucent containers comprising a conveyor (10) for transporting a container (12) through an inspection zone, and means (15, M1,M1,M3) for directing a plurality of light beams (B1,B2,B3) sideways at the container during its movement through the zone. Each light beam is directed at the side of the container from a different direction relative to the container, and deflection means cause each of the beams to repeatedly scan the side of the container in a vertical direction as the container moves fully through each beam.

Abstract: This invention concerns an apparatus for detecting the presence of faults in a translucent container of the kind comprising a scanning zone in which a translucent container is rotated while being repeatedly scanned by a spot beam of light in a direction parallel to the axis of rotation of the container, a light collection apparatus being arranged to receive light from the beam after passing through the container.The light collection apparatus comprises a rectangular matrix of photosensitive devices disposed behind a light-diffusing screen upon whose front surface the light from the scanning beam falls after passing through the container. A rectangular grid of thin white walls is sandwiched between the screen and the photosensitive devices so as to define a plurality of boxes with a respective device being located at the rear of each box.
