| TO EFC. } FROM R.{Sir Henry Royce} -HS{Lord Ernest Hives - Chair}- C.c to BJ. WOR.{Arthur Wormald - General Works Manager} XDS X7625 R2/M3.5.27. 7625 re. SEQUENCE STARTER FOR EAC. 7. X7655 RECEIVED The state of this unit is I believe as follows You have all the particulars for the motor. I refer to the direct drive one with the extra length of carcase, and the teazer circuit, and the spring, to push the armature out of gear, and the contact unit for the main switch, so that this starter unit could be worked with the present standard magnetic main switch and press button. In doing so we should then be trying it without the automatic stopping device. Should we get this to work satisfactorily we can add the stopping device or not, according to whether we find it justifies the complication. From your point of view I understand you are waiting for the new and simplified double magnetic switch. This I have hopes of sending you before the end of next week, but I do not want you to wait for it. You will therefore see that this memo. will leave you in a position that you can - if my view of the situation is correct - test our latest scheme of starter motor arrangement, which should about equal the present gearbox starter scheme, and it suggests that we can or cannot, according to the result of the test, add our special unit of automatic silent stopping control.
