| -2- Hs.{Lord Ernest Hives - Chair}1/WJ.14.2.34. Cont'd.{John DeLooze - Company Secretary} On the aero engine side, I am rapidly coming to the conclusion that evaporative cooling is a wash out. By the time we have fitted mechanical separators, ejectors, low level warning devices, all of which are potential sources of trouble, more than ever I agree with the U.S. opinion that installation difficulties are too great. We are just starting off a test on Ethylene Glycol and we are pressing for the adoption of this on the 600 HP. Kestrel. Hs.{Lord Ernest Hives - Chair} | ||
