| contd :- -2- We should imagine this is a very suitable material for air valves and have made arrangements for one to be constructed. We do not think the anodic treatment would be very satisfactory on anything with wearing surfaces as the oxidised surface is less than one quarter thou: thick. We will report on the air valve of the new material when we have tested it. Hs{Lord Ernest Hives - Chair}/A.C.Lovesey. | ||
