| X.5685. To EFC. from Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} Hs{Lord Ernest Hives - Chair}/Rm{William Robotham - Chief Engineer}1/LG23.12.24. EAC. OIL RELAY GOVERNOR. In answer to your EFC1/T1.12.24. The reply to questions 1. and 2. is in the affirmative subject always to the accuracy at which the controls will be set to prevent toggling. As you will observe from R's. memos., the [handwritten note in margin: when the automatic advance is required] hand control will normally be used for only [handwritten note above: 1/5 of the quadrant] [handwritten over struck-out text: 2 positions], and therefore we have only been concerned about the ignition curves obtained with the control in these two positions. LEC.1917 gives a good illustration of the effect of advance curves when the hand control is moved. It will be observed that the curves are substantially the same. Up to the present the main difficulty with this device has been to induce the oil relay mechanism to function consistently. When we have completely overcome this difficulty we will give you more information as to the exact ignition advanced curves that may be obtained under working conditions.
