[Berkeley Isotope Chart]

Description: Chart classifying the nuclear properties of known elements. The classification and type of radiation of each isotope is identified with abbreviations indicating the half life the isotopes. The elements are organized by atomic number into vertical columns. For each element, the isotopes are organized according to their mass, with the lighter isotopes at the lower end and heavier isotopes at the upper end of the column.

Chart for Determining the Helix Angles of Screw Threads

Description: Chart showing graphically the relationships among diameters, leads, and helix angles of screw threads or other helical surfaces. The range of the chart includes diameters from 0.05 to 10 inches and 1 to 100 threads per inch. Diameters are represented by a vertical logarithmic scale, designated on each side of the chart, and leads on a horizontal logarithmic scale along the top. Vertical lines are drawn corresponding to threads per inch of the various standard systems and these are designated al… more
