| 12-63 EXPERIMENTAL DEPARTMENT. Rm{William Robotham - Chief Engineer}/JBD.{John B. Dixon - Fuel Systems}18/JH. 15th. June, 1939. The S.U. Co.Ltd., Bordesley Green Road, Adderley Park, BIRMINGHAM.8. For the attention of Mr. Cooper. Dear Sirs, We thank you for the two revised specifications PP.16.L. and PP.19.L. and note the addition of the packing ring between the coil housing and diaphragm as requested in spec. PP.16.L. We hope the Neoprene diaphragm will prove as satisfactory in this pump as it has in the Cast Iron pump fitted with the bush and deeper roller recess PP.19.L. In this latter pump PP.19.L. we note the inlet and delivery unions 1701 and 1702 and trust these are for the olive type joint. Will you please ensure that the pumps of this type now on order for the experimental dept. are so fitted. Yours faithfully, FOR ROLLS-ROYCE LTD. | ||
