SEQUENCE STARTER. ---------------- X7655B [struck through] Mr. Royce in his memo R4/M2.12.27. is urging that possibly the rounded end of the teeth which is given to facilitate engagement may for this particular service be the actual cause of jamming taking place. In view of this he therefore suggests that we should make a pair of gears without rounding off the ends of the teeth at all. We think these [circled] gears should be the helical type. BY.{R.W.
