Messrs. Rolls-Royce Ltd. DERBY. Dear Robotham, Many thanks for your letter, and the information you have given me regarding the test carried out on the hydraulic torque converter. I share your view entirely that to come to any hasty conclusion on a device of this kind would be unfortunate. The only satisfactory way is to have one and try it out for a period of time, and satisfy oneself on its characteristics, good or bad. Your reference to the Bendix Co. in the States does not refer to this particular one, and I am endeavouring to find out what type of device they were interested in at the time; but this one has not gone over to the States yet. I am informed in regard to this one that the Italians are taking a very keen interest in it, and at the present moment the Fiat Co. are designing two, which I believe govern almost the whole of the field of their mechanical transport, and if these when tried out give the same results as a very rigid test they carried out in the Apennines not very long ago, they will be inclined to take a serious view of applying it to the whole of the Italian mechanical transport. This particular one seems to have gone further than any other in the matter of efficiency, | ||
