Incidentally, if you could let him see a copy of that paper which I understand you have written for the I.A.E. it would help him to realise that you have made the subject of filtration a life study. We have just had a look at some bearings out of one of our cars which has done 53,000 miles. They are the best we have ever seen at this distance but we do not know whether to ascribe this to our engine design or your filter. Yours sincerely, | ||
