Abstract
557,079. Calculating-apparatus. PIMM, G. B. R. April 30, 1942, No. 5834. [Class 106 (i)] A slide rule calculator calculates the resistance of an impact-driven pile having thereon scales for hammer-blow energy, resistance, temporary compression and co-efficient of restitution. Pointer 9 is set to the hammer-blow energy on scale 2 and disc 4 is rotated until the temporary compression c, found by experiment, cuts the curve of the set in blows per inch, also found by experiment. Pointer 9 is released and pointer 10 rotated until the co-efficient of restitution, already known, coincides with the curve corresponding to the length of pile divided by the weight of the hammer. Pointer 10 then indicates the resistance on scale 3. Studs 5 facilitate the rotation of disc 4.
