Abstract: A process for producing an optimized granular material producing a granular material in a granulating mixer having a container and a stirrer tool, and comminuting at least a part of the granular material in a granular material conditioner which has two elements which move relative to each other, and granular material is passed through a gap between the two elements.

Abstract: The present invention concerns a process for producing an optimised granular material comprising the steps: A) Producing a granular material in a granulating mixer having a container and a stirrer tool, and B) Comminuting at least a part of the granular material in a granular material conditioner which has two elements which move relative to each other, wherein the granular material is passed through a gap between the two elements.

Abstract: A folding device is provided for the processing of workpieces and includes, but is not limited to a holding device for the holding of a workpiece in a processing position in a holding plane and a folding slide for the folding over of an edge of the workpiece into a folding position. The folding slide at least includes, but is not limited to a first folding surface and a second folding surface. The first folding surface with the second folding surface forms an angle ?, the first folding surface with the holding plane forms an angle ?1 and the second folding surface with the holding plane forms an angle ?2 and the first folding surface and the second folding surface are intended for pressing onto the workpiece during the folding over of an edge.

Abstract: An immersion pouring spout for introducing molten metal, such as steel, into an ingot mold is provided with a top head and a cylindrical pouring tube including a protective external jacket attached by cement to the pouring tube and extending the entire length of the pouring tube. The jacket material has a thermal conductivity that is less than the thermal conductivity of the pouring tube material.

Abstract: The raising wheel chair substantially comprises the frame (11), wheels (13 and 15) and the seat (17) pivotably connected to the frame (11). A footrest (21) at the front and a backrest (19) at the back are pivotably connected to the seat (17). For raising the user into an upright position, a spring (27) applies a force which acts counter to the weight of the user, so as to facilitate raising the user to an erect position. A support arm (37) which can be arrested in various positions is pivotably connected to the pivot axis on both sides of the frame (11). To arrest the support arm, the locking lever (41) has a multiplicity of locking positions (45), which can be engaged by a locking element (47). The arm (37) can be put into a horizontal position, in which it offers no hindrance to the user in performing a lateral transfer movement, for instance to shift to a toilet seat.

Abstract: A blast heating apparatus includes an inner metal shell having therein a refractory lining. An outer metal shell surrounds at least a portion of the inner metal shell and defines therewith a double shell structure. Spacers are positioned between the outer and inner metal shells to define therebetween a gap. At least a portion of such gap is filled with a pourable dry material having a grain size of up to 8 mm and a heat conductivity of at least approximately 1.5 W/Km.
