  • Patent number: 4414833
    Abstract: A method of bending a long metal member of constant cross-section by locally heating a narrow zone on the periphery of said member by means of a heating collar (5) which surrounds said zone, by exerting thrust (2) on one end of the member and by supporting its other end by means of a pivoting arm (3). The temperature of the heated zone on the periphery of the member is kept substantially constant by detecting the temperature of this zone or the size of the gap which separates the heating collar from the periphery of said zone at at least two points around said periphery, one of these points being nearest the center of curvature and the other being on the opposite side to the first.

  • Patent number: 4413396
    Abstract: A method for tightening a fastener to yield point wherein areas under a torque-angle curve--each of said areas including a constant abscissa--are successively measured. A decrease of area in a subsequently measured area, indicates that yield point of the fastener has occured. Upon attainment of yield point, the final torque and angular rotation parameters are checked to determine if pre-set values have been realized. The method includes a preliminary torque-angle curve measurement to determine if certain conditions are satisfied; failure to satisfy such conditions, aborts the tightening operation.
