  • Patent number: 10184838
    Abstract: A device for determining the temperature of a road building material applied by a construction machine in a placement width includes an infrared temperature measuring head, a motor and a controller. The infrared temperature measuring head is arranged to be twistable by the motor in a manner transverse to the direction of travel of the construction machine so as to scan the surface of the road building material to capture temperature measuring values of the surface of road building material during a rotational movement at a plurality of measuring points spaced apart from one another. The controller is configured to set a scanning speed as a function of a position of the measuring point.

    Abstract: The invention concerns a soil compaction roller (10) and a soil compaction machine of which the roller (10) forms part. The roller (10) comprises a multi-sided, out-of-round, peripheral compacting surface (16) which can roll over a soil surface which is to be compacted. The compacting surface (16) is defined by a series of angularly spaced salient points (20) and a corresponding series of compacting faces (22). Each compacting face (22) is outwardly convex in shape and extends continuously between two adjacent salient points (20). When the roller (10) is operative with the compacting surface (16) rolling over the soil surface, the roller rises up on each salient point (20) in turn, storing potential energy, and thereafter rolls downwardly onto the succeeding compacting face (22) to transmit the stored potential energy to the soil surface to compact it.

    Abstract: A concrete stamping apparatus includes a roller with a stamp forming its surface, and a receiving portion for rotatably holding the roller. There is also a system for delivering fluid to the roller along its surface, such that it releases easily from the concrete. The receiving portion can be adjustably weighted, such that the roller will stamp the concrete uniformly as the concrete tightens.

  • Patent number: 6652186
    Abstract: A cleat assembly for trash compactor vehicle wheels that does not use pins to attach replaceable cleats to cleat bases on the trash compactor vehicle wheels. The cleat assembly includes a cleat base with a receiving portion that has a cleat base abutment wall. The cleat assembly also includes a re-useable connection system and a replaceable cleat with an interference portion. The connection system includes a biasing portion that is adjacent to the cleat base abutment wall and a locking portion that is adjacent to the biasing portion when the connection system is in use. The locking portion includes a locking section and an interference section that engage the interference portion of the replaceable cleat. The locking section and the interference section are capable of movement relative to one another to thereby couple the replaceable cleat to the cleat base.

  • Patent number: RE40505
    Abstract: A cutting head is provided for milling rumble strip depressions in a road surface. The cutting head has a center rotational axis and a transverse diameter that varies along the length of the rotational axis so that an outer cutting surface of the cutting head defines a plane curve, such as an ellipsoid with truncated ends. The cutting head is mounted on a milling machine and rotated about the rotational axis as it is moved alternately up and down into the road surface. As the milling machine moves down the road, the movement of the cutting head creates spaced apart rumble strip depressions in the road. Because of the elliptical configuration of the cutting head cutting surface, the dimensions of the depressions can be varied along both the forward and lateral axes by simply varying the depth of cut. The curved profile of the cutting head along the rotational axis creates rumble strip depressions that avoid the sharp ninety degree corners and vertical side walls found in conventional rumble strips.
