| r611a Hs{Lord Ernest Hives - Chair}/Wst.2/MA. 16th June, 1936. Messrs.Imperial Chemical Industries,Ltd., 154, London Road, LEICESTER. SEEKAY WAX. Dear Sirs, We have been experimenting for some time with Seekay Wax grade R123 but one of our difficulties has been the high electrical inductivity of this wax which results in the capacity of the windings impregnated with it being increased somewhat. We want a wax having the same melting point as the R123 but with an inductivity approximately the same as pure paraffin wax. Have you anything suitable to offer us or can you recommend any other type of impregnate suitable for our particular requirements. Yours faithfully, FOR ROLLS-ROYCE LIMITED. | ||
