ABSTRACT:
A resistance disk that is so constructed that as the disk is rotated between a pair of fixed contact members, there is produced between the contacts a varying and random like resistance pattern of a character unobtainable with any other form of resistance apparatus and further including the feature whereby the varying resistance pattern may be selectively altered by radial movement of one of the contact members across the face of the disk.
