摘要： A novel trimer of p-isopropenyl phenol of the structure ##STR1## which is useful as a material or a curing agent for epoxy resins. The linear trimer includes a cis-isomer (m.p. 225.5.degree.-227.degree. C.) and a trans-isomer (m.p. 167.degree.-168.degree. C.). It is prepared by reacting p-isopropenyl phenol or its linear polymer in the presence of an acid catalyst such as sulfuric acid, boron fluoride or activated clay in an aromatic hydrocarbon, halogenated hydrocarbon, substituted aromatic hydrocarbon or aprotic polar solvent (e.g., benzene, carbon tetrachloride, nitrobenzene or dioxane).

摘要： A system and method for calculating a sales tax imposed upon a total amount of sales based on a predetermined sales tax collection schedule in an electronic cash register, which schedule comprises a series of the imposable tax values and the corresponding ranges of the taxable sales amounts, a first portion of which comprises a pattern of widths of successive said ranges in for the successively increasing, respectively corresponding tax values which does not occur again in the remainder of the schedule and a second portion of which comprises a pattern of widths of successive said ranges for successively increasing, respectively corresponding tax values which pattern repeats in a regular fashion while the tax value becomes higher. The first and second patterns of width are in advance stored in a storage of said electronic cash register; a usual registering operation is carried out to provide a taxable total amount of sales; an arithmetic operation is carried out to deduct the largest possible integral number of full cycles of the taxable amount of the repeated pattern in said second portion from the taxable total amount of sales; the stored schedule of said first and second portions is indexed for determining a first imposable tax corresponding to said total amount of sales, as deducted; a second corresponding sales tax imposable upon said deducted integral number of full cycles of taxable amount of sales is obtained by multiplication of a full cycle of the imposable tax amount of the repeated pattern in said second portion by said integral number; and the imposable total amount of sales tax is obtained by addition of said first and second tax amounts thus obtained.
