x728. HS{Lord Ernest Hives - Chair} Sent via WW OY2- February 9th, 1929. Mr. F.H. Royce, cc - Mr. Bailey West WitteringHenry Royce's home town, Mr. Hives Sussex, England. London File My dear Mr. Royce: RE ENGINE Stanton's Patents for Spark & Carburation Control. Mr. Wallace Potter of Potter & Johnston introduced to us a Mr. W.F. Stanton who has developed basic patents on the use of the "indicator diagram" to control - Spark Advance. Automobiles & Aircraft. Mixture. Ratio at carburetter. Automobiles & Aircraft. Degree of supercharge. Aircraft. Licenses are carried by General Motors, Pratt & Whitney aircraft, and others, none of which are exclusive. Aircraft. The devices on aircraft engines are under development by Pratt & Whitney at Hartford. We have not seen them but doubtless could do so if you were interested. One interesting point as regards aircraft is the fact that the control of supercharge by "indicator" will automatically compensate for altitude, engine temperature, and even for a change from aviation to commercial fuel, and promises economies for long distance flying. Automobiles. A very old experimental car rigged up with crude devices did not make for a finished demonstration but at least showed that no sort of fine mechanism is called for. Apparatus. This is shown diagrammatically in attached sketch. -continued- | ||
