1. A process utilizing ultrasonic identifying and control means, for coating articles having differing dimensional characteristics comprising:

  • (a) providing a means for moving a series of said articles past a predetermined point to work station;

    (b) detecting the presence of each article when it reaches said predetermined point;

    (c) generating ultrasonic waves from at least two transducers and impinging the waves on each article at said predetermined point to obtain reflected wave patterns from each article thereby to identify its dimensional characteristics;

    (d) electronically comparing and matching the reflected wave patterns with similar numerically code-identified wave patterns in a data base to select a predetermined control sequence program for operating a numerically controlled pre-programmed means for coating each of said articles in accordance with its dimensional characteristics; and

    (e) electronically transmitting the identifying code numbers to the coating means to cause coating to be appropriately applied to each article when it arrives at the work station.
