| To R. {Sir Henry Royce} from EFC. {E. Fowler Clarke - Electrical Engineer} c. BJ. PN. {Mr Northey} Wor. {Arthur Wormald - General Works Manager} c. By. {R.W. Bailey - Chief Engineer} Rg. {Mr Rowledge} EP. {G. Eric Platford - Chief Quality Engineer} c. Da. {Bernard Day - Chassis Design} E. {Mr Elliott - Chief Engineer} ORIGINAL EFC {E. Fowler Clarke - Electrical Engineer} 3/T24.6.26. X.4088 - MIDGLEY CUTOUT AND CONTROLLER. As referred to in EFCl/T24.6.26, please find attached copy of my assistant's report AC.74 dealing with the description of 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 electro-magnetic 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 EFCl/T24.6.26. EFC. {E. Fowler Clarke - Electrical Engineer} | ||
