| X4693 To RHC.{R. H. Coverley - Production Engineer} from Hs{Lord Ernest Hives - Chair}/Gry.{Shadwell Grylls} Hs{Lord Ernest Hives - Chair}/Gry.{Shadwell Grylls}3/KT.19.5.33. OIL COOLERS. We are having considerable trouble on some of the test beds in cooling the oil sufficiently during long runs at high speed. We send you herewith a sketch Hs.{Lord Ernest Hives - Chair}1007 of a small cooler, on the lines of the buick one we have tried, that should dissipate 1000 B.T.U's/min. Will you please make up one of these so that we can be sure the size is correct. We should eventually like one for each test bed if the first is successful.
