| To R.{Sir Henry Royce} from EFC. c. SG.{Arthur F. Sidgreaves - MD} PN.{Mr Northey} EFC3/T25.4.29. X1402 Attached is a page from the 'Electrical Review' of April 12th, giving a method of reducing sparking and wear of regulator contacts, which contacts, as is frequently the case, are shunted by a non-inductive resistance. It would appear that this method would be equally applicable to external dynamo regulators of the vibrating contact type. EFC. | ||
