Abstract : An industrial abrasive unit was modified to enable precise, repetitive abrading of small glass columns. The abraded areas completely circle the tubes at preselected intervals. When such markings are scanned by a light beam - photocell combination, they can be graphically recorded as a series of spikes. The presence or absence of spikes at certain intervals can be transposed into Arabic numbers by using a modification of the conventional binary coded decimal. Using numbers 00 to 99 at the top, bottom, or combination of top and bottom of the tubes permits 9,999 different designations.
