Abstract: The invention relates to a process and device for increasing the separating performance of flue gas desulphurisation installations having at least one reactor (2), to which the flue gas is supplied roughly horizontally at the bottom via at least one flue gas channel (1). In order to equalise the preliminary separating performance in the lower part of the reactor housing (2) and to increase the overall separating performance, the horizontal two-dimensional flow of the flue gas in the flue gas channel (1) is converted into a highly three-dimensional flow simultaneously diverted into the vertical direction by at least one built-in vortex surface (4) arranged in the end region of the flue gas channel (1), producing at least one leading-edge vortex system by forming, prior to entry into the washing zone of the reactor (2), a stationary vortex wake interweaving the flow lines (F1-F4) of the flow in the flue gas channel (1) with each other in a plaited manner.

Abstract: An electrical connector has a release mechanism for releasing a plurality of mating elements. An insulator frame body has a plurality of conductive fixed contacts. The frame body is provided with a plurality of flat plates for moving the mating elements. The flat plates move to release the mating elements from engagement with the electrical connector. A plurality of lever means are pivotally and rotatably supported on the frame body to produce a force required to release the mating elements. Each of the lever means comprises an end portion mechanically coupled to a corresponding one of the flat plates, and an opposite end portion mechanically coupled to one manually operated means. When the manually operated means is pressed in an engaging direction, the lever means are sequentially rotated at different timings. As a result, the flat plates are sequentially moved together with the mating elements in a releasing direction with time delays.

Abstract: The invention relates to a process for purifying or reprocessing a gas in relatively small quantities up to approximately 300 cbm/h, for example and in particular the purification of protective gases or reaction gases flowing off from heat treatments for metals, principally by condensing and/or freezing out the gas utilising the cold of a coolant. A procedure associated with relatively little complexity and enabling a simple and continuous mode of operation comprises, according to the invention, first condensing out with moderate cooling the major impurities having the highest temperatures of liquefaction or vaporisation, for example, water and corresponding materials, and further subjecting the gas to be purified to a cryogenic condensation and/or freezing, the cold requirement for the purification stages being covered by the cold of the coolant, for example and in particular by a cryogenic liquid gas or gases. <IMAGE>

Abstract: On décrit une ailette en bande à configuration décalée (42) conçue pour les échangeurs de chaleur compactes de voitures. L'ailette(42) comporte une pluralité de rangées transversales d'ondulations (44) s'étendant axialement et se chevauchant de manière que la couche limite de l'huile est constamment recréée. Les dimensions des ailettes ont été optimisées pour obtenir un meilleur rapport de transfert de chaleur/chute de pression dans le sens axial. Dans une réalisation, un échangeur de chaleur (30) compacte à tubes concentriques présente une ailette à bande à configuration décalée agencée dans un passage à écoulement annulaire de liquide entre deux tubes concentriques (32, 36). La fourchette préférée de longueurs de chevauchement dans le régime d'écoulements est considérée comme étant comprise entre 0,035 pouces (0,9 mm) et 0.075 pouces (1,9 mm) pour un écoulement développé de manière périodique. Le maintien de la longueur de chevauchement dans le régime d'écoulementdéveloppé de manière périodique présente l'avantage d'offrir un coefficient de transfert de chaleur supérieur à celui qui est possible avec un écoulement entièrement développé. Un avantage supplémentaire réside dans le fait que les variations de la forme des passages d'écoulement n'ont aucun effet défavorable sur le transfert de chaleur.

Abstract: Sheet feed apparatus including a scuff feeder for reliably transporting sheets from the bottom of a stack (S) of sheets without marking of the sheets. The sheet transport apparatus comprises a retard device (24), located in contact with the lead edge, in the direction of sheet feed, of a sheet stack for preventing double feeding of sheets from the sheet stack. A scuff feed belt (22) is located to have a run extending in the direction of sheet feed substantially above the surface of a tray (12) and below the retard device (24) to form a sheet separation nip with the retard device. The run of the scuff feed belt (22) presents an area of contact with the sheet stack to carry about 50% of the weight of the sheet stack. Additionally, the scuff feed belt (22) of the scuff feeder and the retard device (24) respectively have a plurality of grooves oriented in the direction of sheet feed. The grooves assure adequate sheet feeding contact by the scuff feed belt (22) and the retard device in that the lands of the grooves are far enough apart to penetrate any oil on the sheets and collect the oil in the valleys away from the traction area, yet close enough together to prevent localized high pressure points which would result in toner ruboff.
