摘要： The invention concerns an improved method of interconnecting carbon blocks intended for the construction of cathodes in cells for electrolysis of aluminum and the steel bars which connect these blocks to the source of current. The method comprises forming the current supplying bars in two portions or half-bars which are housed in channels provided in the carbon blocks, the half-bars being rigidly connected to the blocks by bedding with cast iron or steel. One or more anchoring points provided near the end of the blocks holds the half-bars in position, while the ends of the bars near the middle of the blocks can expand freely in zones left for the purpose.

摘要： In an opto-electronic head, an optic fiber is coupled with a laser or a light-emitting diode. According to the invention, a plane ceramic substrate acts as a reference plane for the alignment. It is separated into two zones: one zone dedicated to the semi-conductor device and one zone dedicated to the fiber. The second zone supports a heating resistor placed between two insulating layers. A heat barrier, consisting of a slit in the substrate, reduces heat transfers towards the layer to the minimum. To align the two components, a solder preform or polymer preform is put on the resistor. When the preform melts, it forms a drop in which the fiber 4 can be moved in three directions. The invention can be applied to opto-electronic systems.

摘要： An arrangement is disclosed for preventing the molten corium of a nuclear reactor from penetrating into the ground. The reactor is supported by a concrete raft bearing on the ground, and inserted in the raft is a retaining basin having an upper portion of refractory material which is chemically inert towards the constituents of the corium oriented toward the corium, and a lower portion made of a refractory material with a heat conductivity much greater than that of the upper portion. Generally the upper layer of the retaining basin will be made of zirconia and the lower layer will be made of graphite. Disposed between the reactor and the retaining basin is a means for deflecting the vertical attack of corium on the basin and spreading out the corium, comprising a plurality of concentric cavities, each successive cavity having a greater outer diameter than that of the preceding cavity and having a center located at a greater vertical distance from the reactor than the preceding cavity.

摘要： The invention relates to synthetic carbonaceous granules having high mechanical characteristics and, more particularly, the granules produced from anthracite fines. The invention also relates to a process for the preparation of these granules.These granules are produced by agglomeration of fines to the form of pellets, superficial pre-baking of these pellets by an oxidizing gas at a temperature of between 650.degree. and 1000.degree. C. for a few minutes, followed by calcination at a high temperature and, finally, by crushing permitting the desired granulometry to be obtained.The synthetic carbonaceous granules, according to the invention, are used for all types of application and, in particular, for the manufacture of all types of carbonaceous paste, electrodes and carbonaceous blocks for the linings of furnaces or electrolysis cells.
