Abstract

1363561 Function generators NORTH AMERICAN ROCKWELL CORP 3 Jan 1972 [8 March 1971] 154/72 Heading G4G [Also in Divisions B6 and G1] A predetermined non-linear relationship between an input signal and an output signal is derived by means of an arrangement 19. The position of a slider on a potentiometer 18 is directly related to the input signal. Vertical conductor bars 20a are connected with this potentiometer and contact is made to horizontal bars 20b through settable connections 20 (as shown set for a hyperbola function). The bars 20b are connected to tappings on a resistance 21, the amount of resistance thereby introduced varying the output signal derived between 22 and 23. The arrangement forms part of a control system for motors controlling dampening in a lithographic press (see Divisions G1 and B6).
