| X.2512. Extract from EFC2/T5.6.18. (To RHC{R. H. Coverley - Production Engineer}). X.3173 - BATTERY IGNITION. Condenser. None of the condensers so far produced have been up to specified capacity. This is principally due to the thickness of the mica di-electric being greater than was allowed for in the calculations. We have some finer and possibly better mica on order and when we obtain this it will be necessary to make up a number of further condensers in which we shall endeavour to obtain, and probably do so, the required capacity without increasing the size of the condenser. We understand from Mr. Hives that the platinum contact points on the set on 49-GB appear to have suffered rather badly although the same effect has curiously enough not taken place on our test set which has run continuously for three working days. We know from observation that a larger capacity condenser than we have on at present reduces the flash at the points, and therefore when we have made these newer condensers we shall wish to replace those previously made by these new ones. | ||
