Abstract

1,241,462. Resistors. PENNWALT CORP. 1 Aug., 1968 [21 Aug., 1967], No. 2950/71. Divided out of 1,241,461. Heading H1S. An abrading apparatus for removing electrically conductive material from a resistive film, in which the abrasive jet moves with respect to the workpiece and the resistance of the workpiece indicates the correct instant to reverse the motion of the jet and stop the abrasive flow is disclosed, the apparatus being substantially as described in Specification 1,241,461.
