| To Bn.{W.O. Bentley / Mr Barrington} from EFC. EFC5/T24.9.19. Handwritten notes: Top Left: E.F.C. X 3646 Top Right: Write to Capt Briggs RAF Central House Kingsway I spoke to him if he can help us. Bn{W.O. Bentley / Mr Barrington} Stamp: B 24 XII 1919 RECEIVED RE ELECTROLYTIC VACUUM VALVE Mr. Olley is trying to obtain for me a few samples of these valves with which to experiment, as it is suggested that they may be used for limiting the amount of current given by a dynamo in charging a battery, and therefore having application to a lighting set without the necessity of any particular type of regulation on the dynamo. He suggests, however, that you might be able to obtain some of these from the Equipment Dept. of the R.A.F. Do you think you can do this ? E.F.C EFC. | ||
