Abstract
An actuating mechanism for adjusting the angular relationship of co-axial primary and second drives while both are running comprises a double planetary gear train having a freely rotatable common sun gear (201) and first and second ring gears (213, 223) rotatable relative to each other and each coupled to the sun gear by respective sets of caged planet gears (208, 218). One ring gear (213) is normally held against rotation and the other (223) is adjustable relative thereto. The gear cages are fast with the respective drives.
