| To R.{Sir Henry Royce} from EFC. c. CJ. c. Bn.{W.O. Bentley / Mr Barrington} c. E.{Mr Elliott - Chief Engineer} X1402 EFC1/T22.6.20. X.4148. R.R. VIBRATOR REGULATOR. X.1815. X.1482. We are shortly taking up the experimental investigation of the characteristics of vibrator control of the charging output of chassis dynamo. You will remember that in our EFC5/AT26.2.19, we mentioned that Mr. Young of the B.T.H. Co., had told us of a combined vibrator regulator and cut-out, in which the whole business of control could be got very neatly into a small space, the series winding put on for the cut-out operating the series compounding coil for the vibrator regulator. We attach to your copy of this note a small diagram of this arrangement. We would like to suggest that an R-R design of combined regulator and cutout on these lines be got out if you think the combination of the two is fundmentally correct. Otherwise, that a design for vibrator regulator and separate cut-out be produced. If, we, as the Experimental Dept., were provided with all the mechanical details of such a design, we could have one or two of these made up and then could change about and experiment with various shunt and series windings and varying amounts of external non-temperature co-efficient resistance, etc, until we found the best operation electrically.
