Abstract: An apparatus for supporting a vehicle door, the apparatus comprising a base, a first support column mounted on the base, a lift device mounted on the first support column, the lift device comprising at least a first lift bar and a second lift bar each for engaging and together supporting a vehicle door and an actuator operatively coupled to the lift device. When actuated, the actuator imparts vertical movement to the lift device thereby imparting vertical movement to the vehicle door by way of the first lift bar and second lift bar. A second support column is mounted on the base, and the lift device is mounted on and guided by the first support column and the second support column. A load-bearing bridge member spans a space between the first support column and second support column above the base, and the actuator is mounted on the bridge member.

Abstract: An apparatus and method for neutralizing static electric charges are disclosed, which include a cooperating pair of laterally spaced apart electrodes disposed so as to be in a flow path of a moving airstream. A relatively high positive DC voltage is applied to one electrode, and a relatively high negative DC voltage is applied to the other electrode. As a result, the electrodes generates free positive and negative ions, which are carried away by the airstream and delivered directly to the manufacturing area, where they are attracted to opposite static charges. Thus the ions act to neutralize static charges of either polarity, and the excess ions will eventually be attracted to each other or to ground, leaving no static in the area. In a preferred embodiment, the electrodes are mounted immediately downstream of a HEPA filter bank which removes essentially all particulate matter and dust before the ions are generated in the airstream.
