(d) B-end drive couplings. - Two internal gear,
lubricant retaining "Fast"type couplings provide
the drive coupling from the B-shaft,
through a short connecting shaft, to the worm
shaft of the projectile ring drive.
Hydraulic Power and Control Circuits
12. The mechanical arrangements of the drive and coritrol
mechanisms as described above, have complementary hydraulic
arrangements interconnected and functioning as indicated
by the schematic diagrams of figures 32 to 36. These showsequential
phases of the circui t during a full cycle of operation
with flow conditions and resultant movements as explained
in the paragraphs which follow.

lever (S) is moved in the direction to give the ring rotation
de.sired. Motion is carried through gears (9) and (10), lever
(11), control link (12), lever (13), lever (14), link (15) and
hence to mo. ve pump yoke away from its neutral (center) position.
Lever (18) is connected by link (19) to links (20) and
(21). Link roller (22) or (23) contacts its respective timing
cam; depending on direction of pump offset.
