| GRY{Shadwell Grylls} X4037. Hs.{Lord Ernest Hives - Chair} from E.{Mr Elliott - Chief Engineer} E.3/HP.2.3.32. re Oil Cleaner. We send you herewith sample Tecalemit Oil Cleaner, which we should be glad if you will put on test as soon as possible, as we are anxious to know if this device will do what is claimed for it. You will notice that the element capacity is given as 250 G.P.H. We were, however, informed that the drop in pressure when the oil is hot through the filtering element should not exceed .5 of a lb, and 4 lbs per square inch with the oil cold.
