  • Patent number: 11499278
    Abstract: A method of resurfacing a length of roadway or other paved surface having markers thereon includes covering the markers with respective marker covers, applying a coating material to the road and the marker covers, then removing the covers. The marker covers mask the markers from the coating material. An inside dimension of the marker covers should approximate the widest outside dimension of the markers. The inside height of the marker cover can be higher than the height the marker extends over the surface. The cover should rest on the surface and not on the marker, for preferred masking and stability. The weight and shape of the covers should permit them to stay in place despite various disrupting forces. After coating, the covers can be removed or crushed in place.

  • Patent number: 4974755
    Abstract: A dispensing valve assembly and system for viscous materials includes a dispensing valve including a valve casing with an interior chamber, a dispensing port and a longitudinal valve passageway. An inlet port intersects the valve passageay and connects to a source of material to be dispensed. A valve element is slidably received in the passageway and includes a drive shaft portion, an elongated piston head portion and a waisted portion. Seals are provided to seal against the piston head, and the valve element reciprocates over a cycle so that the waisted portion periodically interrupts the first seal allowing material to flow into the chamber and out of the dispensing port. As the valve element closes, a seal is again established to shut off material flow. Continued advancement retracts the piston head further from the chamber to create a negative pressure that draws back material from the dispensing portion to cause a clean cut off of flow. A metering port and a metering cylinder may be employed.
