However, members felt that the use of the term "handbook" would lead one to conclude that it wa3 of a technical nature, and it was finally agreed that the book should be called "Buyers' Plastics Manual" - this to be followed by "Facts Help You Buy and Sell Plastics."

A* Hirschler Date: May 18, 1955 Summary Trends over the past twenty-five years indicate that the refining in dustry will continue to increase the octane number of marketed gasolines, and that these increases will be utilized quickly by car manufacturers in raising engine compression ratios to improve engine efficiency* An increase in the maximum allowable TEL concentration from 3 to k ml/gallon, with a corresponding increase in average actual TEL concentra tions from 2*23 ml/gallon at present to 3*23 ml/gallon, would lead to an increase of about 1*9 in the Research octane number of average gasoline* If this increase were to be accomplished by refinery operation rather than by the use of additional TEL, the production of the same amount of gasoline would require about 2% more crude oil* An increase of 1*9 octane number in the rating of commercially-available gasolines would be expected to lead to an average increase in engine compression ratio of 0*3 ratio.
