| x4562 Hs{Lord Ernest Hives - Chair}/Wst.2/MA. March 10th., 1933. Messrs. C.A.V. Bosch Ltd., Acton, London, W.3. Vibrator Control For Dynamos. Dear Sirs, We shall be glad if you would kindly inform us what large bus undertakings fit your vibrator control unit, and whether you can assure us that this C.A.V. regulator as fitted to these buses has given a minimum of trouble. It will be interesting to know if possible the number of regulators you have in service, as we have received a criticism to the effect that the vibrator regulator is not reliable. With regard to the Bosch type regulators, we shall be very interested if you can furnish us with particulars of Car Manufacturers on the Continent who fit Bosch dynamos and regulators. In effect we should like you to give us all the reassuring information you can as regard to the fitting of vibrator regulators on chassi, for instance definite statistics would be extremely valuable. Yours faithfully, FOR ROLLS-ROYCE LIMITED. | ||
