Abstract: L'invention se rapporte à un appareil (10) et à un procédé de fabrication d'une conduite sous-marine pour grande profondeur ou d'une conduite de très longue portée, par soudage de tuyaux entre eux. On dispose deux tuyaux (2, 4) de manière que leurs extrémités (26, 27) définissent une gorge (28) disposée circonférentiellement et formant un angle faible ( moins de 10 degrés). Au moins deux torches de soudage à l'arc (1) sont disposées de manière directement adjacentes l'une à l'autre sur un unique chariot qui se déplace autour des tuyaux de façon à former un système de soudage à l'arc jumelé. Les arcs des torches (1) forment une soudure (3) dans la gorge. Le chariot est déplacé autour du tuyau et, de ce fait, les torches se déplacent autour du tuyau à la même vitesse. Chaque torche (1) est amenée à osciller indépendamment de sorte que la position de son arc oscille entre les parois de la gorge. Ces arcs sont guidés automatiquement par un système de guidage électronique, dans lequel des caractéristiques électriques de chaque torche (1) (telles que l'intensité du courant et la tension) s'agissant du soudage respectif de chacun des tuyaux (2, 4), sont déterminées et une comparaison effectuée entre les caractéristiques électriques relatives à l'un des tuyaux et les caractéristiques électriques correspondantes relatives à l'autre tuyau. Il est également possible d'aligner l'arc d'une torche (1) avec la ligne médiane de la gorge (28).

Abstract: A method includes steps for modifying tensile stresses in an unpainted canvas that is mounted on a frame under applied tensile stresses. The canvas is formed of material that can undergo heat-shrinking when at or above a thermoplastic shrinking temperature, and can undergo heat-softening when at or above a thermoplastic softening temperature. The method includes heating the canvas to a temperature at or above the thermoplastic shrinking temperature and the thermoplastic softening temperature. The method further includes maintaining the canvas at a temperature at or above the thermoplastic shrinking and softening temperatures. This induces heat-shrinking, and thereby increases the tensile stresses in any portions of the canvas in which the applied tensile stresses are less than the opposing dresses of the heat-shrinking. This also induces heat-softening, and thereby decreases the tensile stresses in any portions of the canvas in which the applied tensile stresses are greater than the opposing stresses of the heat-shrinking. The method further includes subsequently cooling the canvas to a temperature below the thermoplastic shrinking and softening temperatures, whereby the canvas becomes set in a condition of modified tensile stresses.

Abstract: The invention provides a system and method for constructing and maintaining a price structure for an e-commerce transaction relating to a complex product or service. A pricing tree is built of "price components" which include discrete revenues, price adjustments, taxes, and disbursements (such as royalties). Separate revenue streams, which may be allocated to different service providers, may have independent adjustment, tax, and disbursement treatments. Attributes may also be used in the calculation of separate components. Time-date adjustments and rate package adjustments are also supported. The system allows both automated calculation and accounting using the pricing tree. Transactions are supported by a modular e- commerce back-end platform.

Title: Bag house cleaning system
Inventor: ELLIOTT JEFFREY A
IPC: B01D46/02
Filed: 1994-09-01
Granted: 2006-11-21
Abstract: A reverse pulse cleaning system for use in a bag house filter including a blow tube (2) having outlet holes (3) to direct high velocity air pulses into filter bags to be cleaned. The system includes a nozzle (1) which may be an assemblage of parts, which has a control formation at or in between an inlet or outlet of the nozzle. The control formation determines the characteristics such as velocity and direction of the flow emergent from the outlet holes (3) and can improve uniformity and effectiveness of filter bag cleaning. A clampable and releasable fixing of the nozzle (1) to the blow tube allows replacement of the control formation with one of different characteristics during manufacturing or in situ fine tuning. The fixing allows precise alignment of nozzles (1) on assembly which reduces the need for costly precision in forming the blow tube outlet holes (3). The system may include a tube (9) forming part of the nozzle with adjustable radial holes (13) to induce secondary air into the cleaning flow and may include a venturi (10) to induce tertiary air.
