| To - R.{Sir Henry Royce} from MRC. C. to C.W.H. W.E.R. C. to C.P. E.P. X4008 EFG3/T24.6.26. X.4093 - MIDGLEY CUTOUT AND CONTROLLER. X4008 As referred to in EFG1/T24.6.26, please find attached copy of my assistant's report AC.74 dealing with the description/and observations taken upon the duplex unit of the Midgley cutout and controller, together with a photostat copy of diagram in connection with this. We think that sufficient explanation is contained in the report. We have a standard R.R. cutout fitted with a back contact, i.e. contact which makes when armature is furthest from core, and we are looking into the question of arranging this as an electromagnetic switch unit for inserting a resistance in the dynamo field circuit. We think we can with this arrange a satisfactory system of this kind to work on a chassis. The curves referred to in the last paragraph of the attached report are those which have already been issued under cover of our EFG1/T24.6.26. RPC. | ||
