Patent number: 10927516Abstract: 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.Type: GrantFiled: August 9, 2016Date of Patent: February 23, 2021Assignee: Patent Applied TechnologyInventor: David Langtry

Patent number: 10300490Abstract: 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.Type: GrantFiled: July 29, 2015Date of Patent: May 28, 2019Assignee: Patent Applied TechnologyInventor: David Langtry

Publication number: 20160138230Abstract: 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.Type: ApplicationFiled: July 29, 2015Publication date: May 19, 2016Inventor: David Langtry

Patent number: 8550264Abstract: 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.Type: GrantFiled: August 11, 2011Date of Patent: October 8, 2013Assignee: Patent Applied TechnologyInventors: David Langtry, David Langtry

Patent number: 8317963Abstract: 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.Type: GrantFiled: November 21, 2005Date of Patent: November 27, 2012Inventors: David Langtry, William G. Steed

Patent number: 6799689Abstract: 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.Type: GrantFiled: February 26, 2002Date of Patent: October 5, 2004Assignee: Patent Applied TechnologyInventor: David Langtry

Patent number: 6484471Abstract: 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.Type: GrantFiled: March 16, 2001Date of Patent: November 26, 2002Assignee: Patent Applied TechnologyInventors: William G.
