| X14351 W/N. A.{Mr Adams} From Hs{Lord Ernest Hives - Chair}/Lid.{A. J. Lidsey} Hs{Lord Ernest Hives - Chair}/Lid.{A. J. Lidsey}1/MA.2. 5. 32. ANTI FREEZING COMPOUNDS. In reply to A.8/H.30.4.32., we do not think there is anything in the patent held by Prestone to prevent you obtaining ethylene glycol for your own use as an anti-freezing mixture; so long as it is not marketed as such we cannot see how trouble can arise. We have recommended its use for some considerable time in our instruction book without any question being raised. Hs{Lord Ernest Hives - Chair}/A.J.Lidsey. | ||
