    Abstract: The invention relates to a composite paving structure consisting of elements forming a pattern. The structure is made up of laying units each of which has a group of elements adjoining at their respective peripheries and held together by predetermined rupture zones. Supplementing stones are disposed at the boundaries of adjacent units. The stones have one or more elements and extend, in each case, into recesses in both of two adjacent units. Preferably, the stones are of one shape and the pattern is a herringbone pattern. The units may be offset relative to one another in the herringbone pattern.

    Abstract: Undercarriage assembly components of track-type machines having a PTA welded wear-resistant coating and methods for forming such coated undercarriage assembly components are disclosed. Bodies of the undercarriage assembly components, formed of an iron-based alloy, have a material PTA welded on a surface or into an undercut or channel of the iron-based alloy. A heat treatment of the formed component further hardens the body. The portion of the outer surface of the undercarriage assembly components having the wear-resistant coating corresponds to a wear surface of the component during operation of the endless track of the track-type vehicle.

    Abstract: A mower sickle bar has an elongated metal bar having a longitudinally extending edge region that is tempered and thereadjacent a longitudinally extending middle region that is not tempered. The untempered middle region is formed with a row of throughgoing holes. A longitudinally extending row of blades lying on the metal bar at least partially over the untempered middle region thereof is secured thereto by fasteners projecting through the holes and through the blades.
