Patent FR-2500919-A1 (FR)
Inventor: PALMA ENRICO
IPC: F24S10/75
Filed: 1982-02-26
Abstract: In a solar collector, pipes, which are provided for conducting a heat-transmitting fluid, are provided with ribs which are designed for reflection of the solar radiation and arranged parallel to one another and aligned perpendicularly to the pipe axes. The intermediate spaces between these ribs have a cross-section which narrows from a front plate, which is permeable for the solar radiation, towards a rear plate provided with an insulating material and which is produced by a bent shape, in the same direction in all ribs, of the edge regions of the ribs close to the rear plate. The energy of the solar radiation as a result undergoes collection at the narrowest cross-section of the intermediate spaces between the ribs, as a result of which the solar radiation can be better used for heating the fluid irespectively of the direction of incidence.
Patent FR-2524006-A1 (FR)
Inventor: MADSAC MICHEL
IPC: C23C8/32
Filed: 1982-03-23
Abstract: In a surface hardening process for metal parts by nitriding or carbonitriding, the parts to be treated are placed in a furnace and maintained at a temperature of between 490 DEG  C. and 750 DEG  C., in a nitrogen bearing atmosphere, such atmosphere formed by introducing into the furnace a gaseous mixture comprising in particular ammonia and an oxidizing gas for accelerating the catalytic dissociation of ammonia in contact with said parts. The oxidizing gas is nitrous oxide and the gaseous mixture contains about 0.1% to 10% by volume of nitrous oxide. The invention is well suited for the surface hardening of steel parts.
Patent FR-2508058-A1 (FR)
Inventor: O'CONNOR PAUL
IPC: B01J38/12
Filed: 1982-06-21
Abstract: A reactor system for the process has an endothermic cracking zone (6, 7) and an exothermic regeneration zone (13), heat exchange between these two zones being carried out not only via the catalyst circulation stream (5, 6, 11) but also by passing the fresh batch (1) through heat exchange loops (16) arranged in the regeneration zone (13), before the fresh batch comes into contact with the hot regenerated catalyst in a lift pot (4) and passes into the reaction zone (6, 7). The temperature in the regeneration zone is maintained in this manner at a value below 725 DEG C, while the batch is preheated to a temperature of at least 200 DEG C, preferably to 325 DEG C to 400 DEG C. By this means, heavy batches and batches with high metal contents can be processed.
