    Patent number: 4649726
    Abstract: A system for determining the bend in a section of a pipe which comprises supporting the pipe section on a conventional pipe bending apparatus which consists essentially of a device for holding the pipe section in a relatively horizontal position, for maintaining a first end of the pipe section in a relatively fixed position and for exerting a transverse force against a second and opposite end of the pipe section for creating a bend in the pipe section between the two ends thereof; mounting a first transducer on the first end of the pipe section, the first transducer providing a variable voltage depending upon the angle of the first end of the pipe section relative to the horizontal, mounting a second transducer on the second end of the pipe section, the second transducer providing a variable voltage depending upon the angle of the second end of the pipe section relative to the horizontal, exerting a bending force at the second end of the pipe section to create a bend in the pipe section between the two ends t
