Dear Sirs, For the attention of W.A.Robotham Esq. Many thanks for your letter of the 7th on the subject of the anodic treatment of RR.53. Your interpretation of my remarks concerning the firm dealing with the experimental work are correct, except that I do not remember having conveyed to you that they were not well equipped technically. I believe they are, although I have not seen the plant, but I am quite satisfied that they have not tackled the problem of RR.52 either energetically or thoroughly up to the present, and many times I have been very disappointed with the information I have been able to extract from them. We made for them six specially die cast discs for their own dimensions, and supplied them on the 17th May last, and as you know, we are to-day without any results. They can, without doubt, treat successfully alloys containing silicon, but this is because all the experimental work was done in America, and the final results transmitted to them. Very little work, if any, has been done in the States on 122, Y, and certainly not RR.53, so that all the factors | ||
