  • CONCENTRATED SOLAR POWER SYSTEM RECEIVER
    Publication number: 20110067690
    Abstract: Systems and methods for concentrating and storing solar energy are provided. A solar energy receiver for use with the systems and methods may include a container for holding a solar absorption material, such as a phase change material, and a cooled cover disposed above the container for condensing and collecting vaporized phase change material collected along an underside of the cover.

  • Method for improving the performance of seam-welded joints using post-weld heat treatment
    Patent number: 7618503
    Abstract: The present invention provides a method for heat-treating seam-welded constructions of hardenable steel and ferrous alloys with reduced weld-zone hardness and improved weld-zone ductility and toughness. This method consists of heating the seam weld rapidly with a secondary heat source to a temperature greater than the martensitic start temperature but not greater than the lower critical temperature, followed by immediately allowing the seam weld to air-cool. The rapid tempering of this invention is particularly suited to the production of high strength hardenable alloy seam-welded pipe and tubing and other structures.

  • Method for controlling weld metal microstructure using localized controlled cooling of seam-welded joints
    Patent number: 7540402
    Abstract: The present invention provides a method for welding and heat-treating seam-welded constructions of hardenable steel and ferrous alloys with reduced weld-zone hardness and improved weld-zone ductility and toughness. This method consists of controlling the cooling rate of the seam weld with a secondary heat source, applied after the weld cools below the materials upper critical temperature (AC3), but prior to the weld cooling to ambient temperature. This invention is particularly suited to the production of high strength hardenable alloy seam-welded pipe and tubing.
