  • Patent number: 6803741
    Abstract: A method and apparatus for operating a motor controller to cause balanced positive and negative current half-cycles in a motor phase, the method comprising the steps of, for an occurring half-cycle, identifying the most recently obtained valid shut-off angle, identifying the fire angle immediately preceding the identified shut-off angle, mathematically combining the identified fire angle and the identified shut-off angle to identify a next virtual zero crossing (VZC) angle, mathematically combining the next VZC angle and the notch angle to determine a fire angle for the occurring half-cycle and repeating the method for the next half-cycle.

  • Patent number: 6076805
    Abstract: A rope pulling device includes a come-along (20) having a frame (30) on which are mounted an anchor end grip assembly (200) and a load end grip assembly (300). During operation, the anchor end grip assembly is locked on the rope. A hook (100) is carried on the spindle (62) of the ratchet assembly (60). A lever assembly (50) drives a pawl assembly (80) which rotates the ratchet assembly in the forward direction. The hook causes rope to move through the unlocked load end grip assembly and to wind about the spindle. When the spindle is full, the load end grip assembly is locked. A lock assembly (70), which prevents counter-rotation of the spindle is released, allowing the spindle to be reversed and emptied. Slack rope is then passed around the hook, and wound about the spindle for approximately two turns. The load end grip assembly may then be released and the spindle may again be filled with rope, thereby pulling the load (400) closer to the anchor (500).
