| To EFC. } from R.{Sir Henry Royce} Copy to OG. ORIGINAL RECEIVED X.4748 RE VIBRATOR REGULATOR. X.294 X.3533 As it will now be necessary to curtail so much experimental work in your department, I think it will be as well if you will abandon all experimental work on vibrator regulators. I also find that time has been spent on attempting to design a vibratory regulator and cutout; this also should be stopped. Apparently the dynamo with third brush and single field circuit for the third brush will do all you desire, and is the simplest arrangement. Can we not adopt this on the dynamos we are obtaining and making for trial on 40/50 H.P. and "Goshawk II"; concentrate on this. R.{Sir Henry Royce} | ||
