  • Table top rivet setting assembly
    Patent number: 5199624
    Abstract: A rivet pulling head is supported for vertical displacement from an up position to a down riveting position. A rivet delivery device is carried by a movable support and has a delivery arm which can be lowered relative to the pulling head and pivoted underneath it to deliver the next rivet to the pulling head. The delivery device is operated when the head is at the up position and while the head is maintained at that location.

  • Anchor bolt
    Patent number: 5180264
    Abstract: An anchor bolt comprising a threaded stem and a head at one end of the stem; a tubular, hard rubber sleeve held on the stem by a retaining collar nut has a deeply-dished metal washer located on the stem between the head and the sleeve nut with its open end directed towards the sleeve. The dished washer preferably has axial grooves extending from its periphery towards the centre. When the bolt is set, the dished washer is distorted by compression to undercut the hole and the rubber sleeve cooperates with the stem and the walls of the hole to give a very high pull-out resistance.

  • Arc welding of a weld stud
    Patent number: 5171959
    Abstract: Process for welding a weld stud onto a workpiece by means of a drawn arc, in which the weld stud is placed onto the workpiece and, with performance of a welding stroke, is removed from the workpiece in a return stroke, igniting a pilot arc, and is advanced toward the workpiece again in a forward stroke during the combustion of a connected welding arc. The welding arc is divided by pulse-wise current reduction to a minimum value into a sequence of current pulses and the last of these current pulses is extended in time by at least about 1.5 times relative to the preceding current pulses. This extended current pulse lasts substantially to the end of the forward stroke.

  • Bonding head
    Patent number: 5170928
    Abstract: A bonding head for an automatic wire bonding machine, comprises a flame-off electrode which is adapted to be lifted away from an operative position in which it is used to form a ball on the end of the bonding wire, and a capillary through which the bonding wire is supplied to the flame-off electrode. The capillary is also adapted to apply pressure and ultrasonic energy to the wire when it is in contact with the surface to which it is to be bonded. The flame-off electrode is adapted to be lifted away from the operative position by movement of the bond head from a flame-off position to a bonding position.
