Abstract
A system is disclosed for identifying articles emanating in a predetermined sequence from a plurality of sources and formed into rows prior to conveyance to an identification area. The system is particularly useful for identifying glass bottles and, more particularly, for remote marking of defective glass bottles that emanate from glass forming molds so that the defective bottles can be later separated from acceptable ware. The electronic system utilized generates a series of pulses corresponding to formation of each row of bottles to be conveyed and these pulses are coupled to a shift register used for signal delay with the shift register also receiving pulses that are timewise related to the rate of row conveyance. The delayed pulse output from the shift register is coupled through a delay selector switch and fine adjust delay so that the pulse output is delayed a time equivalent to that required from formation of each conveyed row until that conveyed row arrives at the marking, or identification, area.
