Waller - Head of Chateauroux}/2/JAB.23rd March 1937 To. Rm.{William Robotham - Chief Engineer} c. Rm{William Robotham - Chief Engineer}/GWH.{George W. Hancock - Head Chateauroux} 6. B. IV. Oil Pressure Drop on Braking. In response to your Rm{William Robotham - Chief Engineer}/Swdl.{Len H. Swindell}8/AP.13.3.37, we have carried out the tests you suggest, and enclose graphs showing the results obtained. We trust that they are self explanatory. In all cases, acceleration followed directly on braking. It was noted that the gain in maximum oil pressure when the filter element was removed was 3 lbs/sq". Before carrying out these tests, the suction pipe in the sump was checked for air leaks where it enters the suction filter and the special baffle previously fitted was removed. We have received and fitted to-day the new filter and steel pipes and replaced the pipes removed on 3.B.IV. ------------- Rm{William Robotham - Chief Engineer}/GWH{George W.
