Oy2 - G 10122 January 10, 1922 Dear Hives:- Re: Induction Pipes Thanks for yours Hs {Lord Ernest Hives - Chair} 3/LG16.12.21, which exactly confirms our own experiences. We are now using entirely the vaporizer pipes without collector rings but with gas return, as shown in print XA-1400 attached. We find that collector rings make it much more difficult to start and are not really necessary, as mentioned in my letter Oy3-G29.12.21. oy M. {Mr Moon / Mr Moore} Olley | ||
