AT-CULATOR (this name is trademarked); The Circular rule for interconverting weight and atomic percentages
Albany, OR: Albany Enterprises, Inc., 1969. Presumed First Edition, First printing. Pamphlet. This manual is 12 pages, counting the covers. Cover has some wear and soiling. It has illustrations. It provides a description of the AT-CULATOR, the Operation of the AT-CULATOR (including interconverting weight and atomic percentages and Circular Slide rule operations (multiplication, division, combined operations, and proportion). It then addresses the Theory of the AT-CULATOR and provides practice problems and solutions. Dr. Oden appears at some point to have joined the Department of the Interior, Bureau of Mines. Converting from atomic percent to weight percent: For each element listed in the compound, multiply the atomic percent of the element by its atomic weight [the larger of the two principal numbers listed for each element in the standard periodic table]. For each element, let’s call this value p. Add all the values of p together, and let’s call this value p(Total). Now, for each value of p, divide it by p(Total), to obtain w. Multiplying the resulting values of w by 100 gives us the weight percent values, for each respective element in the starting compound. Converting from weight percent to atomic percent: For each element listed in the compound, divide the weight percent of the element by its atomic weight. For each element, let’s call this value m. Add all the values of m together, and let’s call this value m(Total). Now, for each value of m, divide it by m(Total), to obtain a. Multiplying the resulting values of a by 100 gives us the atomic percent values, for each respective element in the starting compound. Condition: Good.
