Abstract
The identification of a mold in which a vessel made from an optically transparent material has been molded. The vessel is provided with a plurality of marks disposed about a path on the wall of the vessel. There is a first set of marks disposed above the path and a second set disposed below the path. One of the first or second sets contains code marks for providing an indication of the mold and the other set contains timing marks suitable for the sequential reading of the code marks. The marks are illuminated by a light path as the vessel is moved and the diffraction or reflection of the light caused by the marks is evaluated. Time impulses are generated in response to the evaluation of the timing marks for sequential reading of the code marks.
