| R6110 Hs{Lord Ernest Hives - Chair}/Wst.13/MA. 24th September, 1935. Imperial Chemical Industries, Ltd., North West Division, 154, London Road, LEICESTER. Seekay Wax. Dear Sirs, We should be glad to know if this wax deteriorates with repeated melting, we require this information as we propose to use this wax for the impregnation of our ignition coils and to use the wax in melted form and remelt it when necessary. It occured to us however that there might be some possible emanation of vapour which causes the wax to chemically deteriorate after a certain time and we should be glad to have your views on this matter. Yours faithfully, FOR ROLLS-ROYCE LIMITED. | ||
