Abstract:
1. An apparatus for carrying out identical continuous records of characteristics on the surface of an object after selected stages of manufacture and treatment of said objects comprising: a rigid frame; a rotary table rotatingly supported in said frame, said rotary table having means for centering said objects and having a center of rotation and a periphery; rotary drive means installed on said rigid frame for rotating said rotary table; a carriage moveable along said guide means and supporting a resonance sensor unit having a resonance sensor based on resonance sensor technology, said carriage having vertical adjustment means capable of adjusting a measurement distance between said resonance sensor and the surface of said object; linear drive means for moving said carriage with said resonance sensor unit along said guide means, said apparatus having an initial position for starting said identical continuous records; first positioning means for accurately positioning said rotary table angularly in said initial position; second positioning means for accurately positioning said resonance sensor linearly in said initial position; third positioning means for accurately positioning said object on said rotary table in said initial position; and a central processing unit connected to said rotary drive means, said linear drive means, first said positioning means, said second positioning means, and said third positioning means, said rotary movement of said rotary table and said linear movement of said carriage being strictly correlated with each other through said central processing unit; said object having a marking item.
