摘要： The process comprises at least a first phase for separating a plurality of particles of molten steel from a bath of molten steel, a second phase for subjecting these particles, while still in the fluid state, to a first system of forces acting on the outer surface of each of the said particles and to a second system of forces acting on each element of the body of each particle, the said two systems of forces being chosen in such a way that these forces tend to impart a substantially spherical form to each of the said particles, and a third phase for removing heat from the said particles sufficient to bring them substantially to the solid state.

摘要： A steering box for a motor vehicle comprises a rotatable toothed pinion, an axially movable rack within a casing, and a support unit to support the thrust which the pinion applies to the rack during operation. The support unit comprises a rotatable roller operable to support the rack. The roller is provided with an axial hold in which is formed a pair of rolling tracks for rolling bodies. A pair of rings are disposed within the hole in contact with one another, each forming with the roller the rolling tracks for the rolling bodies. Two rings of the rolling bodies are disposed between the roller and the rings. A pin supports the rings. The pin is mounted in a cylindrical body provided with a central cavity operable to house the roller, at least patially. The cylindrical body is provided with a pair of slots each of which is able to receive one end of the pin.
