  • Patent number: 10473730
    Abstract: A defect detection device enables easy removal of magnetic impurities. The defect detection device has a structure capable of effectively removing magnetic impurities adhered to a magnetic flux leakage detection device for nondestructive inspection of a small-diameter heat transfer tube or a partially saturated eddy current detection system. With the defect detection device, it is possible to minimize adhesion of magnetic impurities that deteriorate the performance of a leakage magnetic flux detection device for nondestructive inspection of a small-diameter tube of ferromagnetic metal material or a partially saturated eddy current detection system. Further, there is an advantage in that it is possible to remove the adhered magnetic impurities from the defect detection device easily.

  • Patent number: 6676120
    Abstract: The present invention generally relates to a handle assembly for a hand operable bar clamp having a fixed jaw, a movable jaw and a drive for translating the movable jaw towards the fixed jaw. The assembly includes a handgrip and a trigger handle. The handgrip having an elongated rear portion has a generally rounded surface and being contoured to complement the natural transverse curve of a human palm. The trigger handle is pivotal with respect to the handgrip. The trigger handle includes an elongated front portion having a rounded front surface and being contoured to complement the natural palmar curve of a set of fingers flexed toward the palm. The shape and contour of the handle assembly cause pressure to be safely distributed across the user's hand when the handgrip and the trigger handle are grasped and the trigger handle is depressed toward said handgrip.
