  • Patent number: 10927516
    Abstract: Reflective luminescent markings on a road or sign surface are formed by applying onto the surface a base material which is liquid in an initial state for application and sets or cures to form a solid layer after application where the base material contains a fine/medium filler material of glass ground from recycled materials in a rotary mill. Coarse material from the grinder is separated out and supplied as a separate material to be applied onto the surface of the layer of base material and fine ground glass. The base material is connected or impregnated with a luminescent material such as photo luminescent 2 4 6 trichlorophenyl in a binder such as polyurea.

  • Patent number: 10300490
    Abstract: A rotary mill for grinding recycled glass materials into particles has a housing defining an impact chamber with a rotor in the chamber at the bottom of an inclined guide wall underneath the feed opening. The rotor has a plurality of axially extending, angularly spaced massive impact hammers so that the impact hammers impact and deflect the solid materials onto a plurality of shatter bars located at the peripheral wall. Each of the impact hammers has a leading blade element of a hardened steel which has a front face inclined relative to a bottom portion of the guide surface so that an outer edge of the front face is angularly advanced relative to an inner edge thereof.

  • Publication number: 20160138230
    Abstract: Reflective visible markings on a road or sign surface are formed by applying onto the surface a base material which is liquid in an initial state for application and sets or cures to form a solid layer after application where the base material contains a fine/medium filler material of glass ground from recycled materials in a rotary mill. Coarse material from the grinder is separated out and supplied as a separate material to be applied onto the surface of the layer of base material and fine ground glass. The base material can be colored to provide the color required and the base material transparent or both can be transparent and the color provided by the underlying layer.

  • Patent number: 8550264
    Abstract: Containers are mounted in rows on a display rack having shelves inclined upwardly so that articles on the shelf tend to slide forwardly. The containers arranged in rows located side by side across the width of the shelf are formed of board or as transparent plastic jars. Each container has a base on the shelf, upstanding front and rear walls and upstanding side walls with the front and rear walls inclined at a wall angle to a plane at right angles to the base the base so that with the base sitting on the inclined shelf the front and rear walls stand substantially upright. The front wall is higher than the rear wall to provide an exposed strip of each container of the row so that all strips can be seen in front elevation. The strip can be marked with a bar code.

  • Patent number: 8317963
    Abstract: An anchor is fastened into a drilled hole in substrate layer such as concrete by providing on an end portion of the anchor a surrounding layer of an adhesive of a character that it softens when heated and sets when it cools with a portion of the anchor exposed outside the hole. The exposed portion is heated by an inductive heating device in a heating cycle where the heating cycle is actuated by the operator switch but accurately controlled and limited to a single operation in the presence of the anchor by a control in the device in dependence on sensed environmental conditions and a measured size of the anchor.

  • Patent number: 6799689
    Abstract: A shelving rack includes a frame structure including two generally vertical rear legs and two generally vertical front legs and a plurality of shelves formed of welded wire mesh arranged one above the next with a width substantially equal to the width of the rack and a depth between a front edge and a rear edge substantially equal to but greater than the depth of the rack. Each shelf is supported at the front edge either on a wire of the shelf attached across between the front legs or on a transverse beam of the frame so the weight from the front edge is carried by the front legs. Each shelf is inclined upwardly and rearwardly from the front edge toward the rear edge which is elevated with each shelf having an element forming part of a rear stiffener thereof at the rear edge in engagement with a respective one of the rear legs or a transverse beam across the rear legs.

  • Publication number: 20030116463
    Abstract: Elongate articles such as threaded rod and dowels are displayed for sale in a retail situation by inserting them standing generally vertically in a display device having formed from a molded plastics container where a bottom portion forms a base member molded integrally from a plastics material and lid forms a support grid member also molded from a plastics material and arranged to span the side walls. The bottom wall of the base member has upstanding walls for locating bottom ends of the articles. The lid has various openings across it through which the articles extend. The lid is supplemented by small containers at spaced positions therearound and a post each for receiving and displaying related articles. The lids and bases can be stored and shipped in nested condition and erected simply by snapping the lid onto the base.

  • Patent number: 6484471
    Abstract: An anchoring member is provided for anchoring an object to a supporting surface having a bore for receiving the anchoring member. The anchoring member comprises an elongate cylindrical body having a penetrating end arranged to be embedded in the bore and an exposed end opposite the penetrating end. The exposed end is configured differently than the penetrating end for distinguishing which end is to be embedded into the bore. At least part of the outer surface of the body is threaded adjacent the exposed end. An adhesive compound arranged to be coated about the penetrating end of the body secures the body within the bore. A heat generating compound located within a chamber in the body generates ambient heat for assisting in setting and curing the adhesive compound for anchoring the body in the bore.
