| Y3806 To DA.{Bernard Day - Chassis Design} from Hs{Lord Ernest Hives - Chair}/Gy. Hs{Lord Ernest Hives - Chair}/Gy2/LG19.2.29. With reference to the attached. We have now received a print of N.sch.2830 and note that you have allowed for a spring controlled valve. We also note that your 100 lbs. pressure is the max. pressure i.e. at the top of the stroke. We believe that Mr. Bijur uses a system in which the 100 lbs. is the minimum pressure i.e. at the bottom of the stroke. Hs{Lord Ernest Hives - Chair}/F.Gaye. | ||
