| X850 TO DFG FROM R.{Sir Henry Royce} Copy to - OI BY HS.{Lord Ernest Hives - Chair} re. SEQUENCE STARTER. X7650 We have found an excellent way for definitely preventing the undesirable phenomenon found by you - i.e. possibility of motors continuing to drive engine. It consists of arranging the press button so that it makes the two operating circuits separately, that is, when the press button is released the main switch operating circuit is broken. The design of the press button will therefore have to be altered to two way type, but we do not think the modification need cause any difficulty. R.{Sir Henry Royce} | ||
