| 1135 EXPERIMENTAL DEPARTMENT. Rm{William Robotham - Chief Engineer}/Ed.{J. L. Edwards}12/JH. 17th. May, 1939. Messrs. Ferodo Ltd., Chapel-en-le-Frith. For the attention of Mr. Longley. Dear Sirs, Many thanks for your letter of the 15th. inst. and hope that the fans we have despatched will fulfil your requirements for some time to come. With reference to the adjustable diameter pulley angle, we shall be very interested to hear from your Mr. Shilton on this, and we should also like to know whether you have any schemes in your possession of pulleys of this description. Referring to your fan rig, at present we have no fans which we want to test, but expect to have some coming to hand shortly from which power absorption figures will be required. We should be very grateful therefore, if you could test these on the aparatus in your possession. Yours faithfully, FOR ROLLS-ROYCE LTD. | ||
