Dear Heron, I want to thank you very much for the trouble which you have taken as regards the salt cooled valves, and we are looking forward with considerable interest to the tests on these valves. We will let you know as soon as we obtain any results. Am I right in assuming that Nitro Hardened Steel will not work with TEL. dope? I should be very glad of any information you have on this point. Yours faithfully, For Rolls-Royce Ltd. | ||
