摘要：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 marksdisposed about a path on the wall of the vessel. There is a first set of marks disposedabove the path and a second set disposed below the path. One of the first or second setscontains code marks for providing an indication of the mold and the other set containstiming marks suitable for the sequential reading of the code marks. The marks areilluminated by a light path as the vessel is moved and the diffraction or reflection of thelight caused by the marks is evaluated. Time impulses are generated in response to theevaluation of the timing marks for sequential reading of the code marks.
