S t r e e t Ne w Yo r k: May 27,19U5* Dr. Robert A, Iiehoe University of Cincinnati College of Medicine Cincinnati Ohio My dear Dr. Xehoe: Some work has been done in the aviation field in the last year or so on the use of an injector for injecting aniline (or a 60% solution thereto in butyl and ethyl alcohol) into aviation gasoline to give it addi tional anti-knock value at take-off and under full load The apparatus, I understand, is so designed that aniline is bled into the gasoline stream proportionally to the throttle opening which is approximately proportional to the need for anti-knock value Tie are probably going to be asked by the developers of this scheme for a license under our aniline patents I believe that you have some fair ly strong feelings about the'use of aniline von from such a device as this, and I will appreciate your opinion as to what precaution should be taken if aniline is so used Very truly yours, g b /lrj 0015400
