  • Patent number: 9573320
    Abstract: A method, for repairing a discrepant weld in a workpiece arrangement including at least two workpieces, comprising positioning a mechanical intermediary adjacent the discrepant weld and inserting the intermediary through the discrepant weld and into at least a distal workpiece of the two workpieces, wherein upon insertion, a proximate surface of the intermediary is exposed at a proximate side of the workpiece arrangement. The method further includes delivering weld energy to the intermediary. The intermediary is configured, and the weld energy provided, so that energy passes through the intermediary in a pre-determined manner. Energy passing through the intermediary in the pre-determined manner generates heat in material of the workpieces causing the material to melt at an arrangement interface. The method further comprises allowing or causing the material melted to cool, wherein the melted material, when cooled, forms and/or strengthens a robust joint connecting the workpieces.

  • Patent number: 9574971
    Abstract: A method for assessing a cold start emission reduction (CSER) strategy applied to an engine system is provided. The method determines a first accumulation value based on an estimated output signal that would result from applying a first control command to the engine system. The method determines a second accumulation value based on a measured output signal resulting from applying a second control command that implements the CSER strategy to the engine system. The method compares the first accumulation value and the second accumulation value. The method determines whether the applying the second command to the engine system achieved a performance threshold of the CSER strategy based on the comparing.

  • Patent number: 9573194
    Abstract: Spherical particles of one or more elemental metals and elemental carbon are prepared from a precursor in the form of a metal oleate. The metal oleate precursor is dispersed in a liquid vehicle and aerosol droplets of the dispersed precursor are formed in a stream of an inert gas. The aerosol droplets are heated in the stream to decompose the oleate ligand portion of the precursor and form spherical particles that have a mesoporous nanocrystalline structure. The open mesopores of the spherical particles provide a high surface area for contact with fluids in many applications. For example, the mesopores can be infiltrated with a hydrogen absorbing material, such as magnesium hydride, in order to increase the hydrogen storage capacity of the particles.
