Abstract: The screens (114) of a pulp treating vessel (110), such as a paper pulp thickener, or diffuser, are back flushed in a simple yet effective manner. The screens are mounted to a supporting conduit (116) within a vertical vessel, and a cylinder (42) is connected at one open end (43) to the conduit, and the other open end (44) is disposed within the pulp inside the vessel. A piston (46) is mounted within the cylinder and relative movement between the piston and cylinder is effected periodically in order to force liquid from within the cylinder into the conduit and out the screens, backflushing the screens and preventing clogging. Since no additional volume of liquid is added to the vessel during backflushing, no surge occurs in the vessel. Conventional accumulators, on/off valves, and the like can be eliminated while -- in the case of diffusion washing -- efficiency can be increased as much as 20-30%, and capacity increased as much as about 15%.

Abstract: Line trunk groups connected to the duplicated central switching network via correspondingly two time-division multiplex lines each and exhibiting, among other things, one switching stage each and one group processor each are allocated to one another in pairs. The line circuit facilities which are individually allocated to one and the other of two line trunk groups and which are connected to the switching stage of in each case their own line trunk group via internal lines in normal operation, can be switched over to the switching stage of the other line trunk group in each case. So that no connections already switched through or being set up are interrupted up to the point of switch-over, all of the internal lines, which only form connection- individual communication paths for speech, data and the like, can be immediately switched over whereas of the individual associated connection-individual signalling channels only those belonging to unallocated internal lines and those carrying permanent connections can be switched over.

Abstract: The supporting structure of the chair arm consists of two half-parts (1 and 2) in section iron, the second one of which has delimiting parts of the interposed side (4) of the other half-part (1) in order to determine, by means of a passing pivot (5), a rotating articula­tion on a vertical plane with blocking knobs (6) and interposed clotch-disks (7). The first half-part (1) shows an angled appendix (8) fitted in the profile section of the other one in order to allow two stopping positions. In order to bring the two half-parts into an axial prosecution, the second half-part (2) is shifted upwards. When the retention effect of the clutch-disks (7) is over, the low­er part (9) of the angled appendix (8) beats on the inside wall (10) of the second half-part (2). On the contrary, by bringing this sa­me part downwards, the upper wall (11) beats on the inside wall (12) of the second half-part (2). The arm shows the initial half-part (1) brought by the articulation part (13) with variable axle formed by pivot (14) which juts out from the side part (15) and set into eyelet (16) in stop condition by means of the side tooth (17) which beats on strip (18) of the articulation part (13). By pulling the arm out­wards, the articulation (13) of base (18) is unhooked from the tooth (17) by gliding in eyelet (16) of pin (14), thus allowing to bring the arm downwards on the side.

Abstract: La présente invention décrit un appareil et un procédé qui servent à rendre poreuses et à faire fusionner des cellules biologiques au moyen d'impulsions électriques H.F. de puissance élevée. Les électrodes de l'appareil peuvent tenir dans la main ou faire partie d'un équipemet intégré pourvu de récipients spéciaux pour les cellules. Les électrodes, qui sont placées à équidistance les unes des autres, sont attachées à un générateur de fonction de puissance élevée. Le générateur de fonction de puissance peut appliquer à travers les électrodes un champ électrique de courant alternatif continu et/ou un champ électrique H.F. à impulsions à puissance élevée. Le champ électrique alternatif provoque l'agglomération des cellules par di-électrophorèse. Le champ électrique H.F. à impulsions à puissance élevée rend les cellules poreuses ou les fait fusionner. Grâce à un tel procédé, on obtient la perméabilisation ou la fusion de cellules biologiques avec une très grande efficacité. Ce procédé peut être utilisé pour la fusion ou la perméabilisation d'une variété de cellules, telles que cellules animales, cellules humaines, cellules végétales, protoplastes, érythrocytes fantômes, liposomes, vésicules, bactéries et levures. Ce procédé a la propriété unique de rendre poreuses ou de faire fusionner des cellules en très petit nombre ou en très grand nombre. Pendant la perméabilisation ou la fusion, une variété d'agents chimiques, tels que ADN, ARN, anticorps, protéines, médicaments, sondes molléculaires, hormones, facteurs de croissance, enzymes, substances chimiques organiques et inorganiques, peuvent être introduits dans ces cellules. Ce procédé peut également être utilisé pour produire de nouvelles espèces biologiques, pour fabriquer des cellules d'hybridome, qui produisent des anticorps monoclonaux animaux ou humains, et pour introduire des gènes thérapeutiques dans des cellules humaines pouvant être transplantées en retour dans le corps humain pour soigner des maladies génétiques.
