| To Wd.{Mr Wood/Mr Whitehead} from EFC. x3839 EFC4/T1.2.26. X.3839 - THREADED RUBBER SEPARATORS FOR BATTERIES. Answering your Wd{Mr Wood/Mr Whitehead}3/NJ29.1.26, owing to the fact that I shall not feel convinced about the impropriety of making the flat face of the threaded rubber separators face the positive plate, until test shows this to be wrong, we would like, in the case of the P & R, as they do not appear to be so definitely set against it as the Exide, to ask for two of the cells in the battery, i.e. Nos. 2 and 5, to have their flat faces in contact with the surfaces of the positive plates. In the other four cells the more ordinary arrangement of having the ribs against the positive plates should be adhered to. There will be no harm in making the experiment and the main experiment will lose practically nothing by the fact that two of the cells are slightly different. From my experience I am not so sure that even with that arrangement, the threaded rubber separators will not satisfactorily live the life of the positive plates which they themselves are protecting, or at any rate the equivalent life of the positive plates in the other four cells. N.B. If, in accordance with their previous letter they have already put this battery in hand with three and three, there would be no need to ask for this to be altered. EFC. | ||
