| To HP.. c. to RC{R. Childs}/CAP. 6142 Rm{William Robotham - Chief Engineer}/RC.{R. Childs}11/JH.28.6.38. EXPERIMENTAL DYNAMO FOR WRAITH AND BENTLEY. (36 slot armature). Our tests on the first machine of this type show that the angle of retard of the brushes is more than we require. In order to rectify this, the armature connections to the commutator must be lifted and moved one segment round the commutator in an anti-clockwise direction. This is extremely urgent.
