Abstract: Un élément, destiné à un collecteur d'énergie solaire, comprend un tube interne (10, 15 ou 19) portant un fluide échangeur de chaleur, un tube de verre externe (11, 16 ou 20) un espace sous vide (13 ou 21) situé entre les deux tubes et un revêtement de surface sélectif (14, 18 ou 23) se trouvant en contact thermique avec la surface extérieure du tube interne. Un gaz est introduit dans l'espace sous vide (13 ou 21), afin de réduire le vide et de limiter la température de stagnation de l'élément du collecteur. Le gaz est choisi de manière à présenter des caractéristiques hydrophobes, afin d'être adsorbé sur le revêtement de surface sélectif à des températures inférieures à une température prédéterminée, et afin d'être désorbé dans l'espace sous vide à des températures supérieures à la température prédéterminée, tout en n'étant pas adsorbé dans sa majeure partie sur le tube de verre externe. Différentes configurations du collecteur sont prévues pour réduire le niveau de température au-dessus duquel des pertes de chaleur importantes peuvent se produire.

Abstract: This Patent covers the refractory lining of coke-oven doors consisting of 2-layer elements (1, 2) one of these layers being in touch with the door (3) and the other with the coke, the two layers being spaced so as to create a roomy hollow space or chamber (4) for a better upwards discharge of the coke oven gas without external losses, each element being provided with section iron mounting (7, 8) and bolts (9, 11, 12) for assembly of the two layers (1, 2) and to secure the element to the oven door (3). 
     The various elements have different thickness so as to create a slope in the coke wall apt to prevent the coke from sliding down. The two layers are in different materials, i.e. layer 2 in touch with the coke has excellent mechanical properties, whereas the layer in contact with the door (3) has excellent insulating characteristics.

Abstract: Procédé de solidification de déchets industriels avec du ciment, consistant à mélanger les déchets industriels avec un ciment dont le volume ne se modifie essentiellement pas lors de la conservation, et à conserver le ciment pour former des déchets solidifiés. Des substances hydrophiles peuvent être également ajoutées au ciment lors de la conservation. Ce procédé permet de former des déchets solidifiés denses présentant de minuscules cavités, telles des cavités capillaires, ce qui réduit au minimum le dégagement par suintement de substances nocives. En outre, étant donné qu'aucun retrait ne se produit lors de la conservation, le ciment entourant les minuscules particules de déchets ne subit aucun effort de traction, ce qui limite considérablement la perte de résistance des déchets sous forme solide et permet d'accroître la quantité de déchets pouvant être entassés. L'adjonction préalable de substances hydrophiles permet de maintenir le ciment fluide avant la conservation même lorsque l'eau est complètement absorbée par des déchets absorbant l'eau, ce qui présente un très grand avantage lors de la conservation.
