| 81435. Hs{Lord Ernest Hives - Chair} S/W. ANTI-FREEZING MIXTURES. Will you kindly refer to our H1/H3.11.32 and let us have your reply on the matter raised in the final paragraph. We are particularly anxious to draft a letter which may be used generally when customers enquire for glycerine, such as Prices' Zero glycerine, and it is our intention to recommend that they should use Ethylene-glycol or di-Ethylene gly-col and to tell them where they can obtain it as per your Hoy7/MG9.11.32. In the same letter, however, it might be advisable to set forth how the mixture should be prepared, and it is for this reason we should like the above mentioned question to be cleared up. In connection with this matter generally, we note that in Hoy's letter to Prices' Patent Candle Co.Ltd., he refers only to the evil effect that glycerine has on rubber connections. In our letter to customers, however, we would propose to refer to the deleterious effects it has in conjunction with ever present grease or oil on the radiator itself when hard waters are in use. This, in fact, is in accordance with Hs{Lord Ernest Hives - Chair}' memo - Hs{Lord Ernest Hives - Chair}/LIDI/MA5.3.32. Will you confirm that we shall be in order in referring to the bad effect on the radiator itself, as well as on the rubber connections. H.{Arthur M. Hanbury - Head Complaints} SH [STAMP: RECEIVED NOV 18 1932] LID{A. J. Lidsey} See me Hs{Lord Ernest Hives - Chair} | ||
