| 340. To RHC.{R. H. Coverley - Production Engineer} Rm{William Robotham - Chief Engineer}/Std.6/JH.6.1.37. NOISE INSULATED THERMOMETERS. We have noticed on production chassis (particularly P.III) that in fitting up the noise insulation scheme for the thermometer bulb, the capillary piping is often bent so that the bulb is forced over to the limit of its movement and touches the cylinder head. Will you please ensure that the capillary piping is positioned so that the bulb is central with the union and has some free movement in every direction radially.
