Abstract

1437802 Automatic control systems MASSON SCOTT THRISSELL ENG Ltd 18 July 1974 [25 Aug 1973] 40351/73 Heading G3R Ripple generated by a mechanical, cyclically variable transmission between driven and driving inertias is minimized. In the embodiment, motor 21 drives rotary knives 24 via flywheel 22 and draglink 23. The cyclically varying speeds of the knives 24 are normally reflected as ripple in the output of tachometer 26, which is used in a speed control for motor 21. This ripple is reduced by the use of a further cyclically varying transmission 25 between the output of transmission 23 and tachometer 26. The transmissions 23, 25 are chosen so as to have complementary transmission characteristics as Figs. 5 and 6 (not shown).
