| R.{Sir Henry Royce} from E.{Mr Elliott - Chief Engineer} c. to Sg.{Arthur F. Sidgreaves - MD} Hs.{Lord Ernest Hives - Chair} BY.{R.W. Bailey - Chief Engineer} X7510 E1/M4.2.29. VACUUM PUMP OIL PIPE CONNECTION. X.7510 E.7190 Blueprint LeC.2660 attached shews our proposal for the above. We understand that the present connection is made by a tee joint on to another pipe, and this gives trouble by twisting when being tightened. The original drg. is attached to BY's copy of this note.
