Claim 1
Independent Claim
154 words
A GAUGING HEAD MEASURING THE PHYSICAL PROPERTIES OF AN ELONGATED, TRAVELING WORKPIECE IN THE FORM OF A ROD, COMPRISING MEANS FOR LOOSELY GUIDING SAID WORKPIECE FOR LONGITUDINAL MOVEMENT WHEREIN THE CENTRAL AXIS OF THE ROD IS SUBSTANTIALLY CONSTRAINED TO A NOMINAL AXIS OF TRAVEL, ONLY ONE LINE SOURCE OF NUCLEAR RADIATION WHOSE CROSSSECTIONAL DIMENSION IS SUBSTANTIALLY AN ORDER OF MAGNITUDE SMALLER THAN THE CROSS-SECTIONAL DIMENSION OF SAID WORKPIECE LOCATED ON ONE SIDE THEREOF ADJACENT TO A PLANE WHOSE LOCUS IS SAID NOMINAL AXIS OF TRAVEL, AND ONLY ONE RADIATION DETECTOR LOCATED ON THE DIAMETRICALLY OPPOSITE SIDE OF SAID WORKPIECE FOR PROVIDING AN OUTPUT INDICATIVE OF THE AVERAGE INTENSITY OF RADIATION RECEIVED BY SAID BETECTOR, SAID LINE SOURCE BEING PARALLEL TO SAID PLANE AND SO POSITIONED THAT SAID DETECTOR OUTPUT CHANGES IN THE SAME DIRECTION WHEN SAID WORKPIECE AXIS IS MOVED AWAY FROM SAID NOMINAL AXIS OF TRAVEL IN EITHER DIRECTION PERPENDICULAR TO SAID PLANE.
