A flange (23) extends down from the underside of the marker head (22) and is adapted for a close tolerance sliding fit into a channel cut in said walkway surface. There are a plurality of upwardly inclined ribs (25) formed on the flange (23) so that the flange (23) once push fitted into the channel is secured in place without adhesive by outward pressure of the ribs (25) on the sides of the channel.

  • Patent number: 6673417
    Abstract: Anti-slip floor tiles are provided which are textured with a pattern of spikes. The spikes are preferably pyramidal or conical in shape. The height, angle, and base width of the spikes are important to slip resistance coefficients. Preferred spike dimensions range from about 0.2 to about 3.0 mm in height and from about 0.8 to about 3.0 mm in base width (or diameter). Further, a process for manufacturing an anti-slip floor tile which is textured with a pattern of spikes is provided. The tile is manufactured by pressing a powder on a mold, drying the resulting tile, and then firing the pressed tile at a high temperature. The surface texture is formed by the punch of the mold press which includes spike shaped indentations being the negative of the surface of the tile.

  • Patent number: 6659683
    Abstract: An anti-slipping agent for a frozen road surface is provided by crushing a stone having flat-crushability such as black slate into flat-crushed pieces of a required grain size. Furthermore, a method for spreading an anti-slipping agent for a frozen road surface is provided in which the anti-slipping agent for a frozen road surface is heated and then spread onto the frozen road surface. Further an apparatus is provided for spreading an anti-slipping agent for a frozen road surface onto a frozen road surface, which has a hopper, a heater and a spreader.

  • Patent number: 6592288
    Abstract: A high traction anti-icing road cover system; the system includes a pair of base magnetic covers, for example steel plates or flexible non-porous magnetic layers, disposed in grooves in a road surface, such as a bridge span or deck, along the expected tire tracks followed by vehicles. A road cover is constructed of a lamination of a flexible non-porous magnetic layer, an intermediate thermal insulating layer and a tube layer including a plurality of bonded parallel tubes. The plurality of tubes extend obliquely across the width of each road cover. Most of the tubes contain a substance that collapses upon the temperature falling below about freezing; other tubes remain extended above the collapsed surface, to provide better traction in the event of icing of the road surface. All of the tubes are somewhat deformable by the weight of passing vehicles, which mechanically breaks forming ice. Selected tubes may contain a heating coil, coupled to a switch that controllably applies current thereto.

  • Patent number: 6450728
    Abstract: The invention relates mainly to a concrete pavement tile, which produces a clearly recognizable sound when touched with a blind person's cane or a white stick. In practice it appears useful to incorporate sound sources in guide paths for the blind. The invention has solved this problem by providing a pavement tile (1) with an upper plate (3) of metal, which is supported by the tile at its circumference. The plate can be provided with regularly distributed outwardly projecting tears, bumps or ledges (6). Below the plate there is a sound space (2) which can be formed by pressing the plate, upwardly convex, whereas a hollow executed tile gives the same effect.

  • Patent number: 6449790
    Abstract: A transit boarding platform panel comprising a base portion formed from a reinforced composite polymer. The base portion has a top deck and a bottom plate, a first end, a second end, a first side and second side. Between the top deck and bottom plate are a series of internal longitudinal and cross support members. The top deck has a central section and opposite end sections. Detectable warning tiles are mounted to the top surfaces of the end sections. The top surface of the central section has a slip resistant surface. In the preferred embodiment the slip resistant surface consists of a non-slip walking surface coating applied to the top deck. The slip resistant coating should be resistant to the effects of ultraviolet radiation, temperature changes and corrosive elements such as acids, alkalis, salts, phosphates, organic chemicals and solvents such as mineral spirits, gasoline etc. It should also preferably be sufficiently hard to protect against abrasion, chipping, scratching or marring.
