| To Hs{Lord Ernest Hives - Chair}/AJL. from EFC. X.8673 EFC1/T22.11.27. DYNAMO FOR 10,000 MILE TEST. In view of the proposed and impending 10,000 mile test on 12-EX, and the fact that we would like to get the type EG2 Morganite brushes through such a test, we should be pleased if you could arrange to have the N.B. dynamo I from 9-EX which is fitted with such brushes, changed over to chassis 12-EX, and the machine (K) from 12-EX together with the artificial load should be placed on 9-EX. We have a special experimental sandwich battery with threaded rubber separators in the cells on 12-EX and the overcharging which this will receive without the load is what we require. Also we require the high voltage of the overcharging for the test of the EG2 Morganite brushes. EFC. | ||
