  • Patent number: 10227260
    Abstract: A refractory has the form of a dry, mineral batch of fire-resistant mineral materials combined in such a way that refractories which are long-term resistant to fayalite-containing slags, sulfidic melts (mattes), sulfates and non-ferrous metal melts and are used for refractory linings in industrial non-ferrous metal melting furnaces can be manufactured. The refractory at least contains: —at least one coarse-grained magnesia raw material as the main component; —magnesia (MgO) meal; —at least one fire-resistant reagent which, during the melting process, acts (in situ) in a reducing manner on non-ferrous metal oxide melts and/or non-ferrous metal iron oxide melts and converts same into non-ferrous metal melts.

  • Patent number: 7904988
    Abstract: A toothbrush with a bristled head and a handle that includes a pivotable stand. The stand is movable between a collapsed position where an interior surface of the stand is proximate an outer wall of the handle, and an extended position where the stand extends outwardly away from the outer wall and at an angle thereto. This movement is effected by contacting a small flange or a lever on the stand that extends slightly outwardly from the handle. Preferably, the stand is U-shaped and is configured to be received in a complementary cavity in the front wall of the handle. When in the extended position, the legs of the stand together with the end of the handle may be placed in contact with a horizontal surface thereby causing the brush to be oriented in a head-down position with the bristles retained a distance above the surface so that they can drip-dry.

  • Patent number: 7143701
    Abstract: A vehicle collapsible table (28) unfoldable from a vertical rest position between rear seats to a horizontal use position. The table includes a swivel hinge having a profile claw (9) gripping around the edge region of the table board (8) with the said profile claw being attached to a rotary device for swivelling about a swivel axis (11, 34), orientated parallel to the edge (10) gripped around by a profile claw (9), through an angle of approximately 90° such that the table board (28) can be rotated through a rotational angle of approximately 90° about an essentially horizontal rotational axis (15).
