Publication number: 20220057112Abstract: The invention relates to a heliostat sub-assembly and to a method of forming such a sub-assembly. The method of mounting a concave mirror to a supporting structure of a heliostat includes the steps of bonding a plurality of risers at predetermined spaced intervals to a rear face of the mirror, each riser having a bonding pad and a stem extending from the bonding pad, and applying a predetermined concave curvature to the mirror by conforming the front face of the mirror with a convex forming jig or die. The supporting structure and curved mirror are then aligned, and the supporting structure is clinched to the stems of the risers when the curved mirror is conformed with the forming die.Type: ApplicationFiled: December 4, 2019Publication date: February 24, 2022Inventors: Kurt Friedrich DREWES, Bruce Alexander LESLIE

Publication number: 20200355400Abstract: A concentrated solar thermal receiver is mounted on a tower to receive concentrated solar thermal energy from a concentrating array of solar reflectors. The receiver comprises a single layered array of tubes configured to carry a heat transfer fluid such as sodium and defining in combination an exposed concentrated solar thermal energy receiving surface. The array of tubes have a lower fluid inlet header communicating with an inlet conduit, and an upper fluid outlet communicating with an outlet conduit. The tubes are arranged in a serpentine configuration and define a fluid flow path which is predominantly transverse and upward. The receiver includes a thermally insulating cover movable between an open position and a closed position in which the solar thermal energy receiving surface is covered to block or reduce the incidence of solar flux on the tubes or to reduce heat loss from the array of tubes when they are not operational.Type: ApplicationFiled: November 15, 2018Publication date: November 12, 2020Inventors: James Robert FISHER, Allan CURTIS, Kurt Friedrich DREWES, Bruce Alexander LESLIE, Timothy Peter JOST, Nicholas Paul BARTOS

Patent number: 8468724Abstract: A retaining pin assembly for an excavator tooth assembly. The retaining pin assembly has opposable locating members each having a shank portion able to be slidably insertable via a respective retaining pin aperture on opposite sides of a wear member into a transversely extending mounting aperture of a mounting nose of an excavator. Each locating member also has an enlarged inwardly convergent tapered wedge portion adjacent a normally outer end. The retaining pin assembly also has a tensionable retaining member extending between the locating members from one side of the retaining pin assembly. When tension is applied to the retaining member relative contraction of the locating members occurs to urge the wear member into engagement with the mounting nose by wedging engagement between each of the wedge portions and a rear wall of respective retaining pin apertures.Type: GrantFiled: February 29, 2008Date of Patent: June 25, 2013Assignee: CQMS Pty LtdInventors: Bruce Alexander Leslie, Simon Peter Orton, Benjamin Charles Plant, Roderick Mark Bolt
