Patent EP-0409387-A1 (EP)
Inventor: DEANE JOHN D
IPC: E21B10/52
Filed: 1990-05-23
Abstract: A rotary drill bit (10) has three roller cutters (20A, 20B and 20C) mounted thereon for rotation with a plurality of cutting elements (26) arranged in concentric annular rows (28A, 28B, 28C, 28D) thereon. A high velocity drilling fluid is discharged from the nozzle orifices (40, 42, 52) and the orifices are sized and positioned so that more hydraulic energy is directed against the cutting elements (26) in the gage row (28D) than against the cutting elements (26) in the remaining rows (28A, 28B, 28C). The drilling fluid impinges the cutting elements (26) on the leading side of the roller cutters (20A, 20B, 20C) immediately prior to engagement of the cutting elements (26) with the bore hole bottom (30) and then sequentially strikes the bore hole bottom formation at or closely adjacent the juncture (35) of the horizontal bottom portion (32) with the vertical side portion (34).

IPC: B29C48/05
Filed: 1990-10-24
Abstract: A tendon (100,200) for prestressed concrete structure includes a core member (1) such as a steel wire, a steel strand or a steel bar; and an unset bonding material (2) coating the core structure to a predetermined thickness, having a specific setting time determined by selectively determining the respective contents of the bonding material and which sets at an ordinary temperature by chemical reaction; and a seamless corrugated sheath (4) with a long span. 
     The tendon (100,200) is manufactured continuously by coating a wire strand core member (1) with an unset bonding adhesive (2), melt extruding and shrinking a seamless plastic sheath (4) around the coated core member, deforming the plastic sheath (4) to a corrugated shape with the depth of an indented portion being deeper than the thickness of the plastic forming the sheath and cooling the tendon. 
     The tendon (100,200) with a long span is wound on the reel for storage, paid off from the reel and cut to the predetermined length, and anchorages are attached to the end of each reel. The tendon is arranged in a desired arrangement for forming a prestressed concrete structure, concrete is placed so as to bury the tendons therein, and then the tendons are tensioned and fixed after the strength of the deposited concrete has increased to a degree to permit tensioning the tendons and before the unset bonding material sets. Thus, the unset bonding material (2) sets after the tendons (100,200) have been tensioned and bonds the tendons firmly to the prestressed concrete structure.

Abstract: On soumet un matériau devant être congelé à un procédé de refroidissement qui consiste à appliquer des ondes sonores, telles que des ultrasons. L'invention s'applique notamment aux produits alimentaires congelés tels que la margarine, le chocolat et les glaces, mais peut également s'appliquer aux procédés de lyophilisation et de cryoconservation. On peut également soumettre le matériau en cours de congélation à un régime de refroidissement qui élimine efficacement la chaleur latente de congélation, par exemple en augmentant la vitesse de l'extraction de chaleur lorsque la chaleur latente de congélation se libère. L'invention peut permettre des temps de congélation réduits et/ou une viabilité améliorée du produit congelé ou solide.

Abstract: Méthode pour créer une séquence de balayage pour caméra couleur à un seul microprocesseur. Les images typiques captées par un réseau de filtres couleur sont analysées pour déterminer une séquence optimale de balayage pour ledit réseau et/ou lesdites images. Une fois saisies numériquement, ces images sont séparées en bases de données images rouge, verte et bleue, qui sont traitées séparément. Une transformée discrète de cosinus est effectuée sur les blocs de données images et les valeurs quadratiques moyennes des coefficients des images sont calculées. Ces valeurs sont triées par ordre descendant de manière à produire une séquence de balayage descendante qui optimise les performances des schémas de codage de la longueur de passage. La séquence de balayage peut être stockée dans une table de consultation sur matériel informatique, logiciel ou magiciel en tant que liste de coordonnées ou indices de blocs. Elle peut être utilisée par le système pour convertir deux blocs dimensionnels de coefficients en une seule liste dimensionnelle de coefficients adaptés au codage de la longueur de passage. Les coefficients de blocs sont utilisés pour convertir les coefficients décodés en blocs d'images avant leur présentation sur un terminal couleur ou avant la fabrication d'une épreuve couleur. En intégrant cette méthode à un système de saisie d'image, on obtient un système adaptable qui optimise le codage pour différents environnements d'image et/ou différents réseaux de filtres couleur convenant aux différents environnements.

Abstract: Each bonded electrode (14) of the layered-type manganese dry battery has a conductive carbon coat (15') the surface of which contacts the adjacent positive electrode composition (11) and is provided with protrusions of 0.05 to 0.15 mm in height, which serves to prevent the electrodes from sticking to each other even when the electrodes are punched into a prescribed shape by a press mounted with a chute and transported by pressure with the top and bottom of the electrodes facing the respectively specified sides. The protrusions formed on the surface of the coat (15') stick into the positive electrode composition (11), which serves to reduce the contact resistance with the positive electrode composition (11), facilitating the easy maintenance of the low contact resistance. Furthermore, since the contact area with the positive electrode composition (11) facing the coat (15) is increased, the current collecting performance is also improved.

Abstract: An information recording device (Fig. 1) is disclosed, which device comprises write means (3, 8) for providing the record carrier (1) with information patterns (58, 59). The write means (3, 8) are adjustable. In determining the optimum adjustment a calibration procedure is carried out. For different settings of the write means (3, 8) information patterns (58, 59) are recorded. The optimum setting is determined on the basis of the recorded information patterns. The information recording device further comprises storage means for storing in a memory the determined optimum setting together with identification data which indicate for which combination of the recording device and a record carrier (1) the adjustment data has been determined. After a record carrier (1) has been loaded into the information recording device, it is detected whether adjustment data for the relevant combination of a record carrier (1) and an information recording device has been stored in the memory (1, 12). If adjustment data for said combination has been stored the write means (3, 8) are adjusted in conformity with this data and no new calibration procedure is performed, which saves a substantial amount of time.

Abstract: A brake pressure reducing valve assembly (1) comprises first (2) and second (3) normally open valve sets each for controlling communication between respective associated inlet (4A,15) and outlet (4,16) chambers. The first valve set (2) is controlled by a brake pressure responsive piston (6) and a deceleration responsive member (7). The second valve set (3) is controlled by a pressure responsive piston (14). The respective pressure responsive pistons (6,14) are biased apart by a common compression spring (9). In use, the force applied to the piston (14) of the second valve set (3) by the spring (9) is determined by the position of the piston (6) of the first valve set (2) relative to the valve body. Accordingly the pressures at the outlet chambers (4,16) are maintained equal. The valve (1) provides deceleration responsive brake pressure reduction to the rear brakes of a dual braking system without the need for two separate deceleration responsive members.
