Abstract: A device for monitoring the fatigue life of a structural member is comprised of at least one and preferably a plurality of substantially flat, elongated coupons which are fabricated of the same material as that of the member being monitored. The coupons are secured in parallel to the member so that they all experience the same strain history as the member. Each of the coupons includes a different stress concentrating notch pattern so that the application of the same strain to all of the coupons results in the development of different stress concentrations within the coupons. The development of different stress concentrations within the coupons causes each coupon to have a different fatigue life, the fatigue life of each coupon being a predetermined percentage of the fatigue life of the structural member being monitored.

Registration holes are punched about the planar element, so that these may be readily stacked relative to each other, as required to form the surface to be constructed. Sprocket holes are also punched in the sheet material to advance the material along a processing path at which the various processing stations are located.

Abstract: An elongated unhardened blank is passed between a first pair of rollers where it is conductively heated by supplying current to one of the rollers. Thereafter, the blank is further heated by induction and then passed between a second pair of rollers where it is shaped so as to impart thereto a predetermined cross-sectional configuration. The rollers of the second pair are profiled and the blank is maintained at an elevated temperature by supplying current to one of the rollers. After shaping, the blank is passed between a third pair of rollers. Current is again supplied to one of these rollers. The other roller is of a diameter corresponding to that desired for the finished annular articles and the blank is coiled about this roller. This latter roller is partially immersed in a quenching medium so that the blank is quenched and thereby hardened as it is being coiled. Coiling is continued until the number of convolutions corresponds to the number of annular articles which are to be produced.

Abstract: The disclosure relates to a joint-edge element for expansion joints in roadways wherein the anchoring parts, that extend in the longitudinal direction of the joint, just as the remaining parts of the joint-edge profiled element, are joined in one piece to the joint-edge element.
