| COPY. COPY. To E.{Mr Elliott - Chief Engineer} from R.{Sir Henry Royce} Copy to J.{Mr Johnson W.M.} Copy to Na.{Mr Nadin} With reference to the pressure release valves, for some time we have been trying to introduce a pump with a reliable valve, which will only give us the pressure that we need, that is not exceeding two points per square inch. The present relief valve is very unsatisfactory. Please let me know what has been done. R.{Sir Henry Royce} (Sgd) F.H.R. X1092 | ||
