Dear Professor Finch, Many thanks for your kindness in running me over to St.Pancras on Thursday last. Referring to our discussion on induction coils if I sent one of our standard ignition coils down would you be good enough, to produce a few Kathoderay oscillograms of secondary EMF, and current as well as primary EMF. and current. We have never been able to get photographs of the performance of our coils and it would be of great interest to us. We look forward to your visit to Derby and trust you will let us know well before hand of the day you propose to visit us. Yours sincerely, FOR ROLLS-ROYCE LIMITED. | ||
