  • NON-UNIFORM HEAT TREATMENT FOR CUSTOM SPATIAL STRENGTH AND FORMABILITY
    Publication number: 20200010941
    Abstract: Described are metal products having spatially non-uniform strength and formability profiles. The spatial non-uniformity of these properties may be achieved by heat-treating the metal product in a spatially non-uniform fashion, such that different portions of the metal product exhibit different strength and formability characteristics. The metal products may be formed into stamped products, with strength and formability characteristics customized to allow for suitable drawing during the stamping process.

  • Boiler and method of heating liquid
    Patent number: 4528945
    Abstract: In a tube boiler, fuel is burned in a fluidized bed which has a shallower part and a deeper part. The tubes extend only through the shallower part which can be fluidized independently of the deeper part so that the rate of heat transfer from the bed to the tubes can be varied according to demand. Water flows through specially configurated, upwardly oriented tubes by natural convection. There is also a general circulation of particles within the bed.
