    摘要: A method of lining a metallurgical furnace particularly induction furnaces using a form which is placed at a spaced location from the furnace wall comprises filling the hollow space between the furnace wall and the form with a granular and dry refractory material, compacting the material, subjecting the compacted material to a ceramic sintering process by heating it to an intermediate termperature in the range of from about 300* to 800* C. until the material attains a sufficient stability of shape, thereafter removing the form and subjecting the refractory material to a further ceramic sintering process by further heating. A self supporting lining for the metallurgical furnaces comprises a highly compacted and dry structure of a refractory oxide or an oxide mixture to which a dry sintering agent is added and which has been consolidated at a temperature of from between 300* to 800* C.

    摘要: A bogie locomotive with axles which are supported relative to the bogie frame by axle springs and which are linked to the bogie frame by linkage means while the damping of the axle spring system is effected by hydraulic damping means. Each axle side has associated therewith lateral motion abutments and hydraulic damping means which are connected to a first bearing means in the bogie and to a second bearing means in the axle bearing arrangement and which during lifting of the locomotive proportionately absorb the weight of the wheel set and the residual force of the relaxed springs.
