ABSTRACT:
An apparatus for moving samples through a CAT scanner is comprised of a driver table assembly and a follower table assembly. The assemblies are fixedly positioned in aligned spaced condition on opposite sides of a CAT scanner and are adapted to move a sample therethrough with great linear accuracy. The driver table assembly is the active member in moving the sample while the follower table assembly is passive in responding to movement of the driver table assembly. Both table assemblies have lathe heads mounted thereon for securing the sample therebetween in a self-centering manner.
