| X3676. ROLLS-ROYCE OF AMERICA, INC. SPRINGFIELD, MASS. OY-2 Jan. 29, 1930. Cc- Mr. A.J. Rowledge Mr. R.W.H. Bailey Mr. Ellor Mr. Southern (Eng.) Mr. E.W. Hives, Rolls Royce, Ltd., Derby, England. Dear Mr. Hives: STANTON CONTROL DEVICES The fullest description of the scope of the Stanton patents is contained in the French Patent No. 661,979 issued Aug. 1, 1929. The drawings are not very clear so I have not attempted to photostat them. But I believe you would be interested in seeing and studying this patent. I think also E. {Mr Elliott - Chief Engineer} and Da. {Bernard Day - Chassis Design} would like to see it. Have already described the ignition and boost control and the need of injection control on high-speed compression ignition engines. Further variations found in the French patent are as follows:- 1. A rotating disc-valve for "sampling" with means to prevent sticking, methods of lubrication, etc. 2. Use of such a valve for injecting anti-detonants such as water. 3. A rotating and oscillating piston valve. 4. Use of the sleeves or sleeve in sleeve-valve engines for "sampling", by means of small supplementary ports without added mechanism. 5. Poppet valves for sampling, electrically operated. 6. Entirely valveless operation by means of a diaphragm, solenoid, two electrical circuits, and a slide valve communicating with a separate pressure system. 7. Taking a third sample for carburation control, etc. at the end of the suction-stroke. 8. Use of Stanton ignition control with the existing common centrifugal advance. - continued - | ||
