  • Patent number: 11976875
    Abstract: A refrigerator has a shelf seating protrusion and a separate shelf seating member. The shelf seating protrusion is not formed at an approximate mid-point, height wise, of a storage space defined by an inner casing. The shelf seating member may be coupled to the inner casing to support a shelf assembly. An arrangement of the shelf seating protrusions and the shelf seating member is configured to reduce deformation and cracking of the inner casing due to thermal impact in a manufacturing process or when items are stored on the shelf assembly.

  • Patent number: 6296817
    Abstract: Disclosed is the recycling of aluminum dross. Aluminum dross is crushed into particles which are size-classified on the basis of 1 mm. The aluminum dross particles equal to or smaller than 1 mm in size are leached with an aqueous sodium hydroxide solution to give a leachate which contains sodium aluminate as a result of the reaction the aluminum metal of the aluminum dross particles with sodium hydroxide. The aluminum dross particles greater than 1 mm in size are remelted to recover aluminum metal. In the leachate, a small quantity of aluminum hydroxide is seeded, followed by hydrolyzing the sodium aluminate to obtain aluminum hydroxide. Meanwhile, the leachate is filtered to obtain a residue. This residue is subjected to washing, drying and roasting. The mixing of the roasted residue with aggregate and alumina cement gives alumina castable refractories.
