Abstract: A vibratory roller having four drums that can be vibrated. The drums are driven individually, and are mounted in pairs in respective supports. One of the supports is attached to a front frame, and the other support is attached to a rear frame. The object of the invention is to improve the steering condition of vibratory rollers, and especially of trench rollers, in such a way that on the one hand changes in direction during normal travel, or small corrections in direction, can be rapidly undertaken without damaging the already compacted surface of the ground, and that on the other hand it is also possible to make sharp changes in direction practically on the spot. Previously known types of steering for vibratory rollers, namely fifth-wheel steering, transfer steering, articulated steering, and panzer steering, do not permit such a diversified steering condition. Pursuant to the invention, the desired steering condition is achieved by interconnecting the front and rear frames via a hinged or swivel coupling.

Abstract: A mobile paint application and microwave drying apparatus has a downwardly open hollow frame forming a microwave cavity movable over a surface on rollers. The interior cavity of the frame is coated with microwave absorbent material, as are the rollers. The frame in the front and rear conforms to the rollers with a certain gap and ends above the surface at a certain distance. Treads extend between the front and rear rollers on each side and have a thickness which is greater than the gap and distance so as to create a circuitous path from the cavity which blocks microwave radiation. A paint spray nozzle is located in the cavity and applies paint to the surface. This paint is rapidly dried by a microwave generator which is positioned in the cavity and directs radiation onto the wet paint.
