| x9037 BG. c, Hs.{Lord Ernest Hives - Chair} BY11/N.19.4.29. OIL FILTER. Further to our memo BY8/G.17.4.29, I find the Post Script is not correct, and I should have said that the 'Auto Klean' is marketed in this Country by:- Auto Klean Strainers Ltd., Tower House, Trinity Square, London. The Streamline Co.Ltd., make a similar filter in which they use packs of paper washers, and these are so efiective that even colloidal carbon which passes an ordinary filter paper is arrested by these filters. A special small filter is produced by the people referred to for use on Autocars. The filters can be cleaned by reversing the direction of flow and using air instead of oil. Will you please substitute this in place of the Post Script referred to in my previous memo. BY.{R.W. Bailey - Chief Engineer} | ||
