OUR REF................ M/5. 7th June 1928. DIRECTORS: SIR ARCHIBALD C.GOLD WILLIAM PETO F.C. GRAHAM MENZIES C.R.D. PRITCHETT G.R.N. MINCHIN T.W. PRITCHETT Messrs. Rolls Royce Ltd., DERBY. For the attention of Mr. Fowler Clark. Dear Sirs, With regard to the large glass cells which you have, our Works say they have not any pasted positives which could be put into the existing cells and it would mean new cells as and when you wish to renew them. Wood and ebonite separators could be put in when new positive sections are put in and we suggest that when you are ordering any more of these you might order with them wood and ebonite and you could then see whether this prevented buckling better than the three or four rows of glass tubes. Our Works confirm the writer's view that you must not expect too great a life out of the positives with the battery doing the heavy duty that it is, unless you have very much larger cells, which we do not think it would pay you to do as even with renewals as you have been having them, the maintenance upkeep of the battery is a very small sum per annum. Yours faithfully, PETO & RADFORD. G.R.N. Minchin | ||
