    Abstract: A system and apparatus for cutting grooves in a surface includes a housing having a rotatable cutting head mounted therein. An actuator drives the cutting head out of and into contact with the surface. Sensors disposed on the housing sense a depth of the groove cut by the cutting head. A controller is arranged to receive a signal from the sensors and compare the depth of the groove with a predetermined reference depth. The controller sends a signal to the actuator and adjusts the position of the cutting head via the actuator to maintain the depth of the groove at about the reference depth.

  • Patent number: 8647013
    Abstract: The present invention provides a marking system adapted for coating a surface of a substrate in which a drying agent is used. According to a first aspect of the invention, a binder layer, such as paint, is applied to the surface. A drying agent is dispensed into the spray of a binder and becomes incorporated with the binder on the substrate surface. The incorporation of the drying agent into the binder prior to application on the surface provides improved mixing of the drying agent and binder and improved performance. According to a second aspect of the invention, a combination of optical elements and a drying agent are stored in a common hopper and are dispensed into the spray of the binder and become incorporated with the binder on the substrate surface. The mixture of optical elements and drying agent prevents coagulation of the drying agent and the resulting clogging of the dispenser.

    Abstract: An adjustable spacer plate 12 mounts over the US standard screed box 10 thermoplastic opening 14 of 0.125? and creates a 0.090? opening.[This eliminates the need for the user to buy another costly screed box.] For screeding over stencils, the spacer 12 can be flipped to create a zero clearance opening. This allows the thermoplastic to come out only when an opening in the stencil pattern is present. Also, as the die 14 wears down, the spacer can be removed which lets the standard size opening be used as a substitute for the 0.090? opening.

  • Patent number: 8297877
    Abstract: The present invention relates to a rotor box for a ground and/or road milling machine such as, in particular, for a road miller or a trench cutter which surrounds at least one milling rotor for removing ground material (B). It is provided that the wall of this rotor box is configured at least in one section with an enlarged distance from the milling rotor in order to allow a specific guiding of the milled material away from the milling rotor in this region of the rotor box and that at least one separating device is disposed between this section of the wall and the milling rotor, which prevents contact of the guided-away milled material with the milling rotor in this region. The present invention further relates to a ground and/or road milling machine such as in particular a road miller or trench cutter having at least one such rotor box.

  • Publication number: 20120203475
    Abstract: Presented herein are a system and method (i.e., utilities) for monitoring the flow of materials used to mark road surfaces and other surfaces. The utilities utilize one or more pressure sensors to monitor in-line pressure of road marking material to determine the amount of material being applied. Electronic equipment receives signals from the pressure sensors, temperature sensors and/or additional monitoring equipment to generate an output indicative of an amount of material flow. In a further arrangement, the equipment generates an output indicative of a thickness of the read marking material as applied to a surface.

  • Patent number: 8192108
    Abstract: An apparatus to aid in the layout of hashed lines, particularly for laying out lines in parking lots near parking islands and handicapped parking spots is herein disclosed, comprising a large push broom on wheels. Two (2) canisters of marking chalk project downward from a main horizontal member and are spaced so as to produce parallel chalk lines or chalk dots within no parking areas in a parking lot. A guide arm is located on a side of the apparatus such that it can trace the last set of dots and produce two (2) more in an offset, but equally-spaced manner.

  • Patent number: 8177456
    Abstract: A pavement milling sled upholds a rotating pavement milling drum during travel over pavement preselected for milling. Coplanar lower faces of laterally-separated left and right runners configured for sliding travel on the surface of the pavement define a sled floor. A milling frame mounted between the runners circumscribes a milling region, wherein rotation of the milling drum dislodges pavement located in the path the sled below the sled floor, pulverizes dislodged pavement, and deposits pulverized pavement to the rear of the sled. Left and right milling region sidewalls extend upwardly from the sled floor on opposite sides of the milling region. A guard plate is secured between the milling region sidewalls forward of the milling region at a distance above the sled floor. A discharge baffle extends between the milling region sidewalls at the back of the milling region in close proximity to the sled floor.

  • Patent number: 8157473
    Abstract: 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.

  • Patent number: 8128313
    Abstract: A zero velocity bead dispenser is provided for a paint striping vehicle. The dispenser includes an electric motor which rotates a pair of rollers. A bead gun directs reflective particles into the nip point between the rollers, which discharge the particles or beads with a rearward velocity substantially matching the forward velocity of the vehicle. Therefore, the beads are discharged into the wet paint on the road with a net zero velocity so as to minimize or eliminate rolling of the beads in the paint, thereby maximizing the reflective properties of the beads. A speed sensor continuously monitors the vehicle speed and automatically adjusts the motor speed, and thus the roller speed, so as to maintain the relative zero velocity of the discharged beads.

  • Patent number: RE44184
    Abstract: Disclosed is an alkyd resin-based pre-manufactured thermoplastic airport runway signage that is applied in relatively large sections onto an airport runway. The pre-manufactured preformed thermoplastic formed as a continuous sheet and wound onto a take-up spool. The runway surface is prepared with a CCS an epoxy primer and the preformed thermoplastic is unwound from the take-up spool and positioned onto the runway surface. When the pre-manufactured thermoplastic signage is in a desired location it is initially rolled conforming to the runway surface. Heat is applied to the rolled surface to a preferred temperature with an infra-red (IR) heater to melt and adhere the pre-manufactured thermoplastic signage into the runway surface.
