  • Patent number: 6443514
    Abstract: A hoist ring for fixed engagement, in a mounted position, in a threaded bore on a load surface of a load member includes a load bearing ring, a support member and a post. The support member has a cylindrical passage having a first axis and further includes a ring slot to pivotally support the load ring and allow the load ring to rotate about a second axis perpendicular to the first axis such that the load ring freely adjusts to the direction of an applied force. The post has an unthreaded portion in the passage and the passage and the ring slot intersect for the unthreaded, portion of the post to interengage with the load ring to retain the load ring in the ring slot when the post is received in the passage.

  • Patent number: 6441342
    Abstract: A monitor for an electric arc welder as the welder performs a selected arc welding process by creating actual welding parameters, such as arc current and arc voltage, between an advancing welding wire and a workpiece, where the process involves an arc and is defined by a series of rapidly repeating wave shapes constituting a weld cycle with a cycle time, the wave shapes are each segmented into time states having command signals corresponding to the actual parameters and a time duration. The monitor selects a specific wave shape state, reads one of the actual parameters, compares the actual read parameter with a function of the command signal corresponding to the actual parameter, and uses-the comparison to generate a characteristic of the welding process during the selected state.

  • Patent number: 6422377
    Abstract: A band conveyor device used for the suspended transport of plate-like workpieces, metal sheets or the like and has a conveyor belt which is moved along a holding track. A vacuum device holds the goods to be conveyed by suction against a transport side of the conveyor belt. The vacuum device has a multiplicity of suction nozzles which are disposed on the holding track at the transport side of the conveyor belt, so that their nozzle edges which point towards the transported goods to be conveyed are situated at a short distance from the goods. The air necessary for holding the goods is drawn through local, separate invariable vacuum zones, through which the goods pass in succession along the transport path.

  • Patent number: 6420680
    Abstract: A control pedal for a welder that controls the output current level of the welder. The control pedal includes a foot pedal, a start switch, and a current level controller. The foot pedal is movable between an off position, an intermediate position, and a fully on position. The start switch initiates a startup sequence for the welder. The current level controller produces a signal that causes the output current level of the welder to vary between a minimum and a maximum current level. The foot pedal causes the start switch to begin the startup sequence prior to the foot pedal causing the current level controller to generate a signal which results in the output current level increasing above the minimum current level.
