Patent EP-0294919-A1 (EP)
Inventor: KOMOROWSKI JACEK S
IPC: F16H7/12
Filed: 1988-03-23
Abstract: A belt (12) tensioning device (28) having an improved damping mechanism (40) for damping movements of the pivoted structure rotatably carrying the pulley (36) with respect to the fixed structure. The damping mechanism includes a strap (46) and a ring (42) mounted on their respective fixed (30) and pivoted (34) structures, and with respect to one another such that the strap (46) engages the ring (42) with a gripping action sufficient to provide (1) a relatively high resistance to frictional sliding movement between the strap (46) and ring (42) in one direction corresponding to the direction of untensioning of the belt (12) with the pulley (36), and (2) a relatively low resistance to frictional sliding movement between the strap (46) and ring (42) in an opposite direction corresponding to the direction of belt tensioning. A spring (38,94) is included in the mount for enabling the relatively high resistance and relatively low resistance to vary in response to the existence of predetermined vibrations such that the gripping action between strap (46) and ring (42) is relieved sufficiently to enable movement therebetween in both directions to take place at substantially reduced resistance levels.

IPC: C04B35/65

Abstract: The present invention relates to shaped refractory products, particularly in the form of hollow spheres, and to a process for their formation. The process involves dispersing particles of silica or a metal oxide, e.g. Al₂O₃, in an organic polymer, shaping the dispersion into a desired shape, heating the shaped dispersion in a non-oxidizing atmosphere to carbonize the polymer, and heating the carbonized product at high temperature in a non-oxidizing atmosphere containing nitrogen so that some of the oxide is converted to the corresponding nitride and the particles of unreacted oxide sinter together. The ratio of oxide to carbon should be high so that some but not all of the oxide is converted to the nitride and, preferably, only a relatively small amount should be converted. The resulting refractory material is strong and can be used for a variety of uses, e.g. catalyst supports, packing materials and insulating materials.

Abstract: Céramiques présentant une excellente résistance contre les dommages de fusion provoqués par un métal en fusion ou d'autres matières inorganiques. Lorsqu'ils viennent en contact avec une matière en fusion, tel un métal ou du verre en fusion, les éléments composés de céramiques conventionnelles à base de nitrure de bore (BN) sont facilement endommagés au niveau des parties en contact. On peut améliorer visiblement la résistance aux matières en fusion par l'addition de nitrure d'aluminium (AlN) dans une relation correspondant à 1 AlN < 50 % en poids à des céramiques BN contenant au moins 50 % en poids d'un composant BN. La résistance des céramiques BN est améliorée encore davantage par l'addition supplémentaire de 1,0 à 10,0 % en poids de Y2O3 en fonction de la teneur en AlN. Le capuchon protecteur d'un thermocouple composé d'une telle céramique en contact avec un métal en fusion présente une excellente durabilité et permet d'effectuer une mesure en continu de la température du métal en fusion.

Abstract: Un signal vidéo en couleur de mouvement acquis (52) est comprimé, structuré pour être transmis, enregistré sur support de type disque compact (20) et décodé à des vitesses d'images vidéo classiques. Pendant la compression, les régions d'une image sont indvividuellement analysées afin de choisir des procédés de codage de remplissage optimum spécifiques à chaque région. On fait des estimations du temps de décodage des régions afin d'optimiser les seuils de compression. On groupe les codes de description des régions transmettant leur taille et leurs emplacements dans un premier segment d'une suite de données. On regroupe conformément les codes de remplissage des régions transmettant des indications d'amplitude de pixels destinées aux régions afin de remplir le type de code, puis on les place dans d'autres segments de la suite de données. Les segemnts des suites de données sont codés en longueur individuellement selon leur répartition statique respective, puis structurés afin de former des images de données. Le nombre d'octets par image est modifié par l'addition de données auxiliaires déterminées par une analyse de séquence d'images inverse, afin de produire un nombre moyen choisi pour réduire au minimum les pauses du disque compact pendant la relecture, évitant ainsi les périodes latentes imprévisibles de mode de recherche caractértistiques des disques compacts. Un décodeur comporte un décodeur de longueur variable réagissant aux informations statistiques situées dans la suite de codes, afin de décoder séparément en longueur variable les segments individuels de la suite de données. Les données d'emplacement des régions sont dérivées à partir des données de description des régions puis appliquées avec des codes de remplissage de régions à une pluralité de décodeurs spécifiques à des régions, sélectionnés par détection du type de code de remplissage (par exemple, relatif, absolu, dyadique et DPCM), et les pixels des régions décodées sont stockés dans un graphique en mode point pour être ensuite affichés.

Abstract: According to the invention a machine is obtained, which is particularly suited for the cutting of blocks of granite (42), wherein the chain-guiding blade (13) with its corresponding chain (75) and a block of granite (42) which is to be cut into slabs roll in a relative motion without skidding. 
     The place described by the centers of instantaneous rotation (41) is a horizontal line coinciding with the cutting profile (100). 
     The relative non-skidding rolling motion is conveyed to the chain-­guiding blade (13) in one embodiment, while in another embodiment it is conveyed to the block of granite (42) which is being cut. 
     In order to convey the motion to the chain-guiding blade (13) or to the block of granite (42), there are mechanical driving means with a template (26) matching a counter-template (6, 81), or hydraulic devices using cylinders (19, 21) with a control device (97), comprising directional valves and proportional valves, or electro-mechanical means using electric motors with variable speed (63,64) and racks (51, 52).

The gate has a wedge-shape on the upstream side 21 which assists in forcing the seating surfaces together which is highly desirable in high-pressure conditions. The inlet and outlet ports are completely covered in the closed position which enables the valve to withstand extreme pressures. The gate valve further includes a valve stem 10 having a threaded lower end 11 cooperating with a threaded recess in said gate 4, said stem being axially rotatable in a bearing means in said body to raise and lower said gate between said open and closed position, said bearing means including a stuffing box 15, a lower seat and an upper seat through which said stem extends, said stem including an integral collar 12 located between said seats. The upper seat is provided by the stuffing box. The valve body is formed by two members 1a, 1b. The main body part 1a has integral therewith the neck portion 101 containing the bearing means. The cover plate 1b is removably adapted to a side of the main body portion, the cover plate and the main body portion having mating flat surfaces with a trapped seal 30 therebetween in a recess, such that on removal of the cover plate the whole of the interior of the chamber is exposed to permit machining of the interior of the chamber.
