Abstract: A device for establishing a reference datum of a wheeled vehicle comprises a first element operably rotatably mounted to a hub of an axle of the vehicle, the first element having a first axis of rotation, a second element having one end rotatably mounted to the first element so as to have a second axis of rotation perpendicular to the first axis of rotation of the first element, and a laser mounted to the other end of the second element. The laser is oriented relative to the second element so as to project a laser plane either parallel to a longitudinal axis of the second element to thereby establish a vertical datum for the vehicle, or perpendicular to the longitudinal axis of the second element to thereby establish a horizontal datum for the vehicle.

Abstract: An apparatus for drying wet roadway surfaces, and more particularly, paved race tracks. The drying device has a rectangular, box-shaped housing with first and second chambers. The first or leading chamber has a first drip pan for collecting water. At least one brush is rotatably mounted in the first chamber such that the longitudinal axis of the brush is oriented transversely to the device's direction of travel when removing water. The brush is adapted to contact the surface so as to collect water in the brush as the brush rotates. The brush is also adapted to contact the first drip pan so as to dislodge the collected water in the brush and deposit the water into the drip pan. First and second squeegees are mounted respectively to the first and second chambers for diverting water away from the surface over which the apparatus is traversing. Finally, a blower is mounted atop the housing for forcing air into the second chamber for evaporating water on the surface not already collected by the brush.

Abstract: A coke oven door comprises a door frame, a plate mounted so as to be freely movable relative to the door frame within limits and a seal operatively mounted to the plate and positioned around the periphery of the frame for effecting sealing against the jamb of a coke oven. In a preferred form, the door comprises a first plate mounted so as to be freely movable relative to the door frame within limits and a second plate mounted to the first plate, having a seal mounted around the periphery thereof and having refractory plugs mounted thereto. Force applying members are mounted around the periphery of the door frame and are selectively adjustable to contact and move the first plate. Force applying members are mounted around the periphery of the first plate and are selectively adjustable to contact and move the seal. Angle sections mounted to the door frame and retainer clips mounted to the first plate cooperate to limit movement of the first plate.
