  • Patent number: 9388539
    Abstract: Methods of and apparatus for controlling relative telescoping extension or retraction of multiple telescoping assemblies is provided. The telescoping assemblies connect the main frame of a slipform paver to a side member of the slipform paver. Each telescoping assembly has a telescopic lock associated with the telescoping assembly. A common telescoping force is applied across the telescoping assemblies to widen or narrow the frame width of the slipform paver. Extension of the telescoping assemblies is monitored, and activation of the telescopic locks is controlled so as to determine which of the telescoping assemblies is allowed to telescope under application of the common telescoping force.

    Abstract: A self-propelled construction machine, in particular a road milling machine, recycler, stabiliser, finisher or roller, comprises a machine frame, on which a working unit is arranged, and comprises a drive unit for driving the working unit. An additive, in particular a urea solution for operating an exhaust gas treatment system, is provided in an operating material tank which is integrated in the fuel tank or water tank of the construction machine. The integration of the operating material tank in the fuel tank or water tank does not necessitate any modifications to the machine frame, and therefore it is not necessary to have different production lines for construction machines having or not having an exhaust gas treatment system.

  • Patent number: 8308394
    Abstract: Embodiments of the present invention relate to systems and methods implemented in a pothole patching system for creating a vacuum that pulls heavy particulate, such as gravel, out of a hopper. For example, according to an embodiment, a vacuum body having a vacuum chamber formed therein is positioned proximate to an opening of the hopper. A moveable slide gate is provided between the vacuum chamber and the opening of the hopper. The slide gate moves between open and closed positions for permitting and blocking communication between the vacuum chamber and the hopper. A reduction nozzle is provided between an air source and the vacuum chamber. Forced air flows from the air source, through the reduction nozzle, and into the vacuum chamber. The reduction nozzle reduces the pressure of the forced air entering the vacuum chamber, and thereby creates a vacuum in the vacuum chamber. When the slide gate is in the open position, this vacuum pulls particulate from the hopper.

    Abstract: The machinery system and its application herewith, intended to create an opening in the roof of a Reactor Primary Containment of Generation II and III Nuclear Power Electric Generating Station. This opening is necessary to replace an aging nuclear reactor with a new, safer and more efficient reactor. Generation II and III Nuclear Power Electric Generating Stations include General Electric (GE) Boiling Water Reactor BWR/2, 3, 4, 5 and BWR/6 located in Mark II, and Mark III wet containments and Pressurized Water Reactors manufactured by Westinghouse, Combustion Engineering and Babcock and Wilcox located in dry containments. Until this time, existing reactor replacement was not possible due to Reactor Primary Containment structural enclosure configuration. The Dual Head Vertical Milling Machine System will remove a Reactor Primary Containment Dome Segment thus providing an opening, allowing reactor replacement and the electric generating station to remain operational for an other 40 years and beyond.

  • Patent number: 8052347
    Abstract: A floating screed device has a first section for cutting through plastic concrete and a second section for floating on the plastic concrete. The two sections are pivotally coupled for rotational movement about a pivot point. Elevation of the second section is measured and used to rotate the first section as the floating screed device is moved through a volume of the plastic concrete that is unfinished. As a result, the second section pitches to follow the first section.
