| X.50 COPY. R5/B23713. 23rd July 1913. Mr Ellis from F.H.R. Copies sent to:- J.{Mr Johnson W.M.} Wor.{Arthur Wormald - General Works Manager} [Handwritten note] X.50 X.607 Re Exide Cells X.607 and Edison Cells X.50 I still await comparative weights of Edison and Exide lighting accumulators. Re the question of E.M.F. there is nothing to choose; also, when the engine slows down below charging the lights need not be very bright. I did not see this point at first. What current does the average set of lamps take ? ----------------------- Don't expect me to find back numbers of papers for reference. I have no time and the work is wasted. Mr Ellis should have all at hand in his note books. ----------------------- F.H.R. COPY. | ||
