  • Patent number: 9575567
    Abstract: In a preferred form, a keyboard has a single row of eight multi-position keys with the letters arranged in a standard QWERTY keyboard configuration. The eight keys correspond to the eight fingers used when touch typing; each finger operates one key, and that key contains all the letters that the finger normally accesses when touch typing on a standard QWERTY keyboard. With this design, no finger has to move to a different key while typing. When depressed at different locations on its key face, each key either moves straight down, or down while tilting slightly about one of a plurality of axes. Three-position keys have two tilt axes and six-position keys have five tilt axes. The keys utilize contacts located on the bottom of the keys which may be conductive or nonconductive.

  • Patent number: 8956075
    Abstract: A slip-mold having a housing having (a) concrete hopper having (b) means for distribution of quick set concrete within said hopper, (c) a mold cavity, and (d) at least one tunnel, in communication with said mold cavity, and extending through said housing from the leading to the trailing end of said housing. The tunnel through the housing is of sufficient height and width, and positioned within said mold housing, to permit rebars, extending from an iron work array, to pass through said mold cavity without becoming embedded in concrete, concurrent with the formation of a slip formed concrete structure on a portion of said iron work array.

  • Patent number: 8920068
    Abstract: A process for slip forming of concrete structures, specifically, concrete structural components, for road and bridge construction. This process has particular application for slip forming of monolithic structures having multiple component/functional parts, wherein the resultant slip formed monolithic, structure has exposed rebars bar the later integration with additional concrete structures arid/or mechanical structural elements, c,g. noise walls, barricades, guard rails and the like. This invention also includes a system adapted for the formation of these unique, monolithic slip formed structures with exposed rebars, including the tunnel mold assembly, which is utilized in this slip forming process; and, the resultant to slip molded monolithic structural component with exposed rebus.

  • Patent number: 8221027
    Abstract: A powered roller screed (366) is disclosed, that uses a dual-drive power unit (370) and a screed roller (368). A power source (372) of the dual-drive power unit (370) includes a first drive output (374) and a second drive output (376), which rotate in the same direction and at the same rate. Each of the first drive output (374) and the second drive output (376) may be used to rotate the screed roller (368). For instance, the first drive output (374) could be attached to a first end of the screed roller (368), or the second drive output (376) could be attached to the second end of the screed roller (368), all to rotate the screed roller (368) in the same direction as the screed roller (368) is being pulled over wet concrete (364).

  • Publication number: 20100266339
    Abstract: A paving machine that moves in a travel direction spreads, levels and finishes concrete into a form having a generally upwardly exposed, finished concrete surface that terminates in lateral sides. The paving machine has a main frame with first and second bolsters arranged at opposite ends of the main frame. Each set of bolsters has two hydraulic jacking columns used to raise and lower the machine frame. Crawlers attached to the bottom of the jacking columns engage the ground and move the paving machine in the travel direction. A paving kit is secured to the machine frame and has a substantially rigid center portion oriented transverse to the travel direction. It terminates in lateral ends and is disposed between the bolsters. A variable length terminal paving kit is secured to each lateral end of the center portion.

  • Patent number: 7168886
    Abstract: The present application relates to methods for laying a traffic calming surface, in which molten material is deposited on the surface of a road or path and is then moulded so as to form a continuous, substantially sinusoidal profile which extends along the intended direction of travel. The profile can be formed by employing at least one pair of longitudinal rails which are positioned on the surface of the road so as to be spaced apart from each other and such that they are aligned with the intended direction of travel. The upper surface of the rails exhibits the required profile so that molten material deposited between the rails can be spread between the rails to form the required surface.

  • Patent number: 6508606
    Abstract: An apparatus for continuously shaping and extruding a longitudinally extending curb of moldable material. The device provides a self-contained and self-powered platform for modular curb forming inserts of multiple disciplines including auger extrusion and vibratory slip form. Moldable material is supplied to a feed hopper for the modular auger/slip form inserts that creates and dispenses a shaped curb bed. Leveling sensors and guides compensate for irregular surface gradients maintaining the orientation of the formed curb shape.

  • Patent number: 5971656
    Abstract: A hot-mix motorized paver is used to deliver fresh pervious pavement mix to form one or more lanes of pavement. The paver is supported on ski-type support runners on parallel side forms. A compacting roller is connected to the paver and rolls along the top of each side form to compact the fresh pavement down to the top of the forms. Indentations are cut into the fresh compacted pavement by rolling a hand powered roller, containing a pointed hoop, across the fresh pavement at select locations to form expansion joints. The pavement is covered with polyethylene sheeting within 20 minutes after completion of placement and finishing, the sheeting is removed after a curing time of approximately seven days, and a concrete saw is used to remove excess pervious pavement that extends beyond the desired paved area.

  • Patent number: 4706317
    Abstract: Apparatus and method for pouring concrete on a bridge is disclosed employing rail-mounted pouring and related equipment and separate rail-mounted rolling pipe for attachment to a concrete source system located on an approach to the area to be poured. The equipment rail and rolling pipe rail are both mounted on stable overhang brackets located outboard of the area to be poured. A power tractor is also mounted in the approach area on the rolling pipe rail and straddles the vertical reinforcing members located on the outside edges of the bridge deck. The tractor pushes the rolling pipe and permits a flexible hose connection to a stationary concrete pump located on the approach. A spring-loaded telescoping channel connection allows the trolleys on the tractor and the idler trolleys supporting the rolling pipe to be clamped securely to the rail.
