RECEIVED X3032 Re - Impregnating Aluminium Castings. R8/W26917. With reference to impregnating the aluminium castings with silicate of soda, I should think this would be so very simple that it might be tried on such castings as are only slightly porous. I should not recommend that the definitely bad ones were treated in this way, but scrapped. R.{Sir Henry Royce} | ||
