The direction of the action of force can be changed according to a change in the surroundings of the vibrating plate, particularly to the slope and/or the hardness of a subsoil to be compacted by a soil contact plate. Alternatively, the direction of the action of force can be changed according to the wishes of the operator.Type: ApplicationFiled: June 23, 2006Publication date: December 2, 2010Applicant: WACKER NEUSON SEInventors: Michael Fischer, Otto W.

Publication number: 20100290836Abstract: A preferred embodiment of the invention provides a method of placing visible advertising on the upper surface of a road (1). This method includes determining the location of any traffic control signs that are applied to the surface of the road, such as the location of signs (22, 25). Following from this, two exclusion zones (31, 32) are defined. These zones extend from the respective signs (22, 25) and terminate at a predetermined minimum distance from the signs. Advertising is then applied to the surface such that it overlies neither the signs nor the exclusion zones. Particularly, the advertising has been placed in the areas bounded by rectangles (33, 34), which are respectively disposed within lanes (7, 8).Type: ApplicationFiled: May 19, 2010Publication date: November 18, 2010Applicant: RHINO ADVERTISING PTY LIMITEDInventor: Caleb Myers

Publication number: 20100272509Abstract: A traffic barrier section is disclosed herein. The traffic barrier section includes a prefabricated or pre-cast concrete barrier wall section and a poured in-place (i.e., in-situ) moment slab footing. As constructed, the traffic barrier section is suitable for constructing a continuous protective barrier for a roadway. In that regard, a plurality of traffic barrier sections are placed side-by-side in close proximity and supported on a retaining wall to form a continuous protective barrier along the edge of the roadway. In use, the erected continuous protective barrier restrains a moving vehicle on the elevated roadway from traveling over the edge of the retaining wall.Type: ApplicationFiled: April 27, 2009Publication date: October 28, 2010Applicant: TRI-STATE CONSTRUCTION, INC.Inventor: Greg Ritke

Publication number: 20100270044Abstract: An apparatus for removing markers from pavement includes a prime mover and an implement adjustably coupled to the prime mover. The implement includes a body, a tool having a working tip, a leveling pointer pivotably coupled to the body such that the leveling pointer moves relative to the body under the force of gravity, and a target indicium disposed near the leveling pointer. In some embodiments, the apparatus may further include a camera focused on the working tip of the tool and a display visible to an operator of the prime mover. A method of removing a marker from pavement includes positioning the working tip of a tool at a predetermined distance from an edge of the marker embedded in the pavement; adjusting the implement to a predetermined angle relative to an upper surface of the pavement by rotating the implement until the leveling pointer is aligned with the target indicium; and advancing the implement to remove the marker from the pavement.Type: ApplicationFiled: April 23, 2009Publication date: October 28, 2010Applicant: Fayette Fabricators, IncorporatedInventor: Steven C.

Publication number: 20100215432Abstract: The invention provides blocks made of certain material, equipped with drainage and ventilation functions, and a side of the blocks formed with first interlocking part and second interlocking part in the opposite but corresponding side while other two sides without the interlocking part formed with ventilating channels penetrating the center of the block unit and other areas without first and second interlocking parts equipped with chamfered channels in certain length and width. The blocks of the invention are paved in multi-layers and equipped with numerous ventilation channels and longitudinal grooving. Thus, the multi-layer structure provides sound drainage of water and moisture while preventing subsidence of road via maximizing the maintenance period of the pavement.Type: ApplicationFiled: May 15, 2007Publication date: August 26, 2010Inventors: Heung Sik Yu, Seong Kyun Jin
