| 133/ Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls}6/MH.{M. Huckerby} 25th. July, 1939. The Avon India Rubber Co. Ltd., Melksham, WILTS. For the attention of Dr. Mackay. Dear Sirs, Herewith, as promised, sketch of the hydraulic measuring apparatus which we have been using for determining tyre loss. It has since been modified, in that the gauge is now fixed to the wall and connected to the cast iron box by a long length of small bore pipe. This prevents vibrations causing fluctuations of the needle. Yours faithfully, for ROLLS-ROYCE LTD. | ||
