Abstract: Des palettes individuelles à about (A, B, C) contenant du béton moulé ou tout autre matériau nécessaire à la fabrication de tuiles, alimentent un premier transporteur à chaîne (4) qui les transfère ensuite à un second transporteur de même type (5). Les deux transporteurs déplacent les palettes au moyen de cliquets qui s'engrènent dans une fente ménagée à la surface inférieure de chaque palette. Le deuxième transporteur avance plus vite que le premier. de manière à séparer les palettes. Un chariot de va-et-vient (30) transporte des outils, par exemple une coupeuse de coins (41) ou une poinçonneuse (40). En sens avant il se déplace à la même vitesse que le deuxième transporteur. Les outils sont actionnés en synchronisme avec les positions des cliquets sur le deuxième transporteur.

Abstract: A method and apparatus are employed to reduce the sulfur dioxide produced by the combustion of a sulfur-containing fuel in a combustion chamber. Part of the combustion air is introduced into the combustion chamber with and closely adjacent the fuel. Another part of the combustion air is introduced into the combustion chamber above and downstream of the fuel and relatively remote therefrom under conditions which buffer the flame front and reduce peak flame temperatures therein. Finely divided limestone particles or the like are aspirated into the combustion chamber by the air introduced above the fuel and distributed thereby throughout the gases flowing downstream through the combustion chamber wherein the limestone particles are calcined to lime particles which react with the sulfur dioxide in the combustion reaction gases to produce calcium sulfate. There is no premixing of the particles and the aspirating air before they enter the combustion chamber. Various parameters are controlled to produce the desired results.

Abstract: For positioning a tool carrier (WT) of a multiple machine tool, on which a plurality of tool units (B1 ... B3) with a multiplicity of tool spindles (W1 ... W21) are fitted, the positions of the tool spindles (W1 ... W21) with respect to the tool carrier origin (WT0) are specified by using the respective drilling unit origins (B10 ... B30). From combinations of different tool spindles (W1 ... W21) it is possible to configure drilling modules to which in each case a leading tool spindle (W1 ... W21) is assigned. The geometrical distance of the tool spindle (W1 ... W21) to be positioned from the tool carrier origin (WT0) is taken into account in the position calculation as a position correction. <IMAGE>

Abstract: In order, in a construction, especially a dwelling or holiday house, to be able to cast the walls and the intermediate floor situated above in one step from concrete without having to attach a separate ceiling form after erection of the walls, it is proposed to use for each room of the construction a room form consisting of a plurality of assembled form elements (4) which bound the room and of an inflatable balloon envelope (5) which is arranged in this room. After inflating the balloon envelope, the latter completely fills the room surrounded by the form elements (4) and covers it in the manner of a dome. If a formwork erected in this way is filled with concrete, the wall surfaces of the rooms are defined by the form elements (4), whereas the ceiling surface is formed by the dome-like balloon envelope. The external form elements (1) are for this purpose at least as high as the storey height plus the thickness of the intermediate floor. <IMAGE>

Abstract: An apparatus is disclosed for use in a drill string 10 to prevent separation of a lower tubular member 16 from an upper tubular member 15 by a rotational force applied from a down-hole motor 22. The down-hole motor 22 is rotated by drilling fluid pumped from the surface, through a passage formed within the drill string 10, and into the down-hole motor 22. A valve 36 is positioned in the passage in the drill string 10 and has a first operating position adapted for passing the drilling fluid to the down-hole motor 22, and a second operating position adapted for substantially blocking the drilling fluid from being delivered through the down-hole motor 22. The valve is of a two piece construction, having a first body 44 connected to an upper tubular section 14 and a second body 46 connected to the down-hole motor 22. Thus, longitudinal movement between the upper tubular section 14 and the down-hole motor 22, which is a result of rotation of the lower tubular section 16 by the motor 22, causes corresponding longitudinal movement of the first and second bodies 44, 46 between the first and second operating positions.

Abstract: A jet condenser of the type comprising a water chamber in a mixing chamber (24) and an after-cooler (52), wherein the water chamber is subdivided in a narrower upper water chamber portion (38a) and a broader lower water chamber portion (38b). The after-cooler (52) is fixed at the junction (66) of both water chamber portions (38a, 38b). Cooling water is injected into the mixing chamber (24) by nozzles (40) of the upper water chamber portion (38a) where it flows in vertical direction.

Abstract: Les conditions d'écoulement d'un volume d'eau sont réglées au moyen d'un mélangeur à cloche (4) présentant un disque profilé (6) et une cloche de distribution rotative (7) en forme générale de croissant. Le disque profilé comporte au moins trois ouvertures traversantes, dont une première est en communication avec la conduite d'entrée de la chaudière (KV), une seconde (12) avec la conduite montante de chauffage (HV) et une troisième avec la conduite de retour de la chaudière. La cloche de distribution (7) est sollicitée à l'extérieur par la pression de l'eau de retour du chauffage et comporte, à l'intérieur, un canal de communication (19). La cloche de distribution court-circuite, sur une zone limitée de position en rotation, l'entrée de la chaudière par l'intermédiaire de la seconde ouverture traversante (12) avec la conduite montante de chauffage, et libère en même temps un domaine variable de la section d'ouverture de la seconde ouverture traversante, pour le mélange de l'eau en retour. On obtient ainsi un réglage optimum en ne faisant appel qu'à un nombre restreint de moyens mis en oeuvre sur le plan construction, entretien et exploitation.

Abstract: A gene coding for BBRP42, which is a protein secreted in an earlier stage of incubation, is cloned from a genomic DNA library of  Bacillus brevis  to construct an expression vector containing a signal peptide coding region and a transcription controlling region. By incubating a host carrying a recombinant plasmid containing a foreign gene joined immediately downstream of the signal peptide coding region, it is possible to allow a foreign gene product to be secreted from the host in an earlier stage of the incubation where a protease is not secreted so much, thus enabling an efficient recovery of the product.

Abstract: The present invention relates to a vibration isolation apparatus provided, for example, between a vehicle body and an engine to absorb vibration from the engine and other parts of the vehicle. An outer cylinder (12) is mounted on a vibration receiving portion (13). A plurality of elastic members (14) are adhesively bonded to an inner periphery of the outer cylinder (12). Frame bodies are independently fixed in the vicinity of an axis of the outer cylinder (12) so as to support the respective elastic members. An inner cylinder (36) is provided between a plurality of elastic members (14) to force the elastic members via the frame bodies toward the outer cylinder (12). Therefore, no distortion remains on the frame bodies, and compressive force can be applied to the elastic members even if the inner (36) and outer cylinders (12) are relatively displaced due to vibration. Durability of the elastic members can therefore be improved.
