The reason we suggested carrying on with alumiliting ourselves was that we had begun to despair of getting results in any other manner. We arranged with Mr. Brookes of the Light Production Co.Ltd. to send to the Alumilite Co.Ltd. a set of pistons. He also send a set of test pieces in RR.53 alloy. We have repeatedly been in communication with Mr. Brookes, urging him to return these pistons to us so that we could start tests, but he has told us that he has been unable to get satisfaction from the Licencees. As his whole job is pistons, he is as keen as we are to get the job moving. We wrote him again after receiving your memo., and received the following reply :- "I am quite satisfied that they have not tackled the problem of RR.53 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 on RR.53, so that all the factors necessary for successful treatment of these materials have had to be determined in England." | ||
