| To RHC.{R. H. Coverley - Production Engineer} x340 Hs{Lord Ernest Hives - Chair}/Std.9/KW.15.11.35. Ph.III Radiator Steam Valves. We do not think that we can make the present Ph.III radiator steam valve work satisfactorily unless we make it even more elaborate than it is at present, and are of the opinion that it is too complicated and expensive as it is. Will you therefore detail and make the scheme Rm.{William Robotham - Chief Engineer}12 attached. This will utilise a diaphragm from one of the "Camel" type valves which we possess, and should therefore be quite satisfactory. This scheme can be fitted to the radiator matrix and top tank removed recently from 33-EX. Hs{Lord Ernest Hives - Chair}/Std. | ||
