    • A load transporting vehicle has a plurality of independently steerable wheel sets, each of which incorporates a turntable having a downwardly extending strut and a pivotally mounted trailing arm that carries a pair of wheels. The turntable is rotatably mounted on the vehicle frame. A pair of double acting piston and cylinder assemblies are coupled to rotate the turntable via a rack and pinion. A hydraulic control valve, having a control spool actuated by a boden type cable, controls the flow of hydraulic fluid to the piston and cylinder assemblies.The linear movement of the boden cable is programmed and controlled by rotatable cams. Three or four sets of cams, each set of which controls a different mode of steering, are mounted on a rotatable shaft. Each set of cams has a single cam to a given boden cable and associated wheel set. The sets of cams are interleaved to form groups corresponding to each wheel set. By axially shifting the shaft, a cam follower connected to the boden cable disengages from one cam and engages a next adjacent cam to change from one mode of steering to another. A cam follower lifting mechanism is provided to raise the followers from the cam surfaces during the shifting procedure.

    • A personnel door for sealing a room having a source of Radio Frequency (RF) radiation. The door when swung into a closed position can be energized to be partially disposed in an opening below floor level directly beneath the door. Sealing between the door and the door frame of the room can occur around the borders of the door including the part disposed in the opening below floor level. A step up into the room or use of a ramp to gain access to the room is thereby eliminated. In the preferred embodiment, the door is retained above the opening below floor level by springs and energized to move vertically downward into the opening against the force of the springs by an air cylinder.
    • 用于密封具有射频(RF)辐射源的房间的人员门。 摇摆到关闭位置的门可以被通电以部分地设置在门下方的地板下方的开口中。 门和门框之间的密封可以在门的边界周围发生,包括设置在地板下方的开口中的部分。 因此,消除了进入房间或​​使用斜坡进入房间的步骤。 在优选实施例中,门通过弹簧被保持在地板下方的开口上方,并通过气缸被激励以垂直向下移动到开口中,抵抗弹簧的力。
