  • Patent number: 6746712
    Abstract: The present invention pertains to an arrangement for the controlled application of adhesive to substrate. In at least one embodiment, the arrangement comprises a) an adhesive reservoir, b) a pump, c) an applicator head having at least one applicator nozzle, d) a volume throughput sensor, and e) a monitoring unit. The reservoir, the pump, and the applicator head are connected together by a conduit system carrying the adhesive. The volume throughput sensor and the monitoring unit are connected together by a pulse transmission line. The monitoring unit, the feed pump, and the applicator head are connected together by control lines. In at least one embodiment, the application of adhesive to substrates is controlled by measuring the volume throughput of the adhesive, transmitting signals indicative of volume throughout to the monitoring unit, and controlling the amount of adhesive applied to the substrate material in-line in response to the signals.

  • Patent number: 4945697
    Abstract: A floor or walkway has a base and an overlay on the base. The overlay includes a plurality of prefabricated tiles each of which has an upper layer designed to contact objects on the floor or walkway and a lower layer designed to bear against the base. The upper layers are composed of a ceramic while the lower layers are composed of a resilient material having anti-skid characteristics. The upper and lower layers of each tile are adhesively secured or vulcanized to one another during manufacture of the tile. The overlay is formed by simply placing the tile on the base or loosely securing the tiles to the base by means of an adhesive. If the overlay is outdoors, the same or gaps between neighboring tiles are kept open to permit water runoff. The lower layers of the tiles are then formed with drainage channels and/or open pores for the discharge of water which has passed through the seams or gaps.
