| r1282 Hs{Lord Ernest Hives - Chair}/Wst.1/JH. 28th July, 1936. F.R.Banks Esq., The Ethyl Export Corporation, Thames House, Millbank, London, S.W.1. r60010 Dear Banks, Have just returned from holiday and have noted the correspondence between Rm.{William Robotham - Chief Engineer} and yourself regarding misfiring on K.L.G. 850 plugs when used with Ethyl. I have been thinking hard about the whole business a lot lately and wondered whether you could give me any information in response to the following questionnaire :- (a) Is a short blunt nosed insulator less prone to lead deposit, of a nature such as to cause misfiring, than a long insulator nose like the 850 K.L.G.? (b) Is there any test to which we can submit plugs to detect leakage ? Our ordinary electrical tests seem valueless as they shew the plugs to be O.K. with practically infinite resistance. (c) Is there a critical temperature at which lead deposits form of a conductive nature and which when subjected to higher temperatures become non-conductive. | ||
