Abstract: A hanging device for a cross-sectionally trough-shaped, downwardly open supporting rail (5) of a false ceiling possesses a vertical hanger part (1) having a flat, hammerhead-shaped anchor piece (4). The anchor piece (4) is inserted through an insertion slot (10) into the web face (7) of the supporting rail (5). The two edges of the insertion slot (10) are formed by a single longitudinal cut in the web face (7) and are bent apart perpendicularly to the web face (7) to such an extent that between them a gap is formed which is sufficiently wide to permit insertion of the anchor piece (4) in the inclined position into the insertion slot (10). The hanger part (1) can be set vertical only in an anchor hole (11) at the end of the insertion slot (10). In this vertical position, unintentional detachment of the hanger part (1) from the supporting rail (5) is prevented. <IMAGE>

IPC: B01J15/00

Abstract: A hollow fiber bundle element is provided comprising a bundle of microporous hollow fibers disposed in a cylindrical impermeable casing. With respect to each fiber, its wall is selected to provide a permeability in the microfiltration range (0.05 to 5 micrometers). The bundle forms two longitudinal passageways, being the lumina of the fibers and the other being the void space between the fibers. A first of these passageways is densely and uniformly packed with minute solid particles. No binder is used to fix the particles - they maintain their distribution in the passageway as a result of having been densely packed under pressure. The ends of the first passageway are sealed and the fiber wall pores are smaller than the particles, whereby the particles are immobilized therein. The hollow fiber module packed with minute adsorbant particles in the first passageway provides an adsorber. A fluid mixture comprising a carrier and an adsorbate is introduced into the second passageway. The adsorbate diffuses through the fiber walls and is collected by the adsorbent particles. By way of result, the particles used in this adsorber can be of much smaller size than those used in a conventional fixed bed column. The use of small adsorbent particles enhances adsorption rate, and availability of a separate longitudinal flow passageway reduces pressure drop across the adsorber. Alternatively, the hollow fiber module may be packed with minute catalyst particles to provide an effective catalytic reactor with improved mass transfer between the catalyst particles in the first passageway and surrounding fluid containing the reactants, in the second passageway.

Abstract: Un polypeptide destiné à être produit en levure comprend une fusion d'un peptide signal, d'un peptide de tête et d'une protéine ou d'un polypeptide hétérologues. Le polypeptide est modifié dans sa séquence d'acides aminés ajdacente à un site de traitement de levure situé entre l'extrémité de terminaison C du peptide de tête et l'extrémité de terminaison N de la protéine hétérologue, de façon à fournir une présentation du site de traitement qui rend accessible celui-ci au clivage protéolytique. On assure une telle présentation en ajoutant un ou plusieurs acides aminés (dont au moins un est chargé négativement) soit à l'extrémité de terminaison C du peptide de tête soit à l'extrémité de terminaison N de la protéine, ou aux deux. La protéine hétérologue peut par exemple être constituée par un précurseur d'aprotinine ou d'insuline ou par un analogue de ce précurseur.

Abstract: Des circuits de réseau logiques programmables, de multiplexeur et de réseau de mémoire utilisant la logique MOS complémentaire dynamique de l'invention, sont capables de fonctionner à des vitesses approximativement égales à deux fois celles de circuits similaires utilisant une logique MOS complémentaire dynamique classique. Le circuit de l'invention présente un plan ET défini par une série de colonnes d'entrée (64) et par une série de rangées (68), et présente un plan OU défini par la série de rangées (68) et par une ou par plusieurs colonnes de sortie (69). Des transistors (70, 71) sont connectés sélectivement entre les colonnes d'entrée (64) et les rangées (68), et entre les colonnes de sortie (62) et les rangées (68). Pendant un état d'une entrée (O1) d'horloge extérieure dans le circuit, chaque entrée d'une série d'entrées (A, B, C) est placée dans une colonne respective des colonnes d'entrées (64), chacune desdites colonnes de sortie (69) étant préchargée, et chacune des rangées (68) étant déchargée. Le passage de l'entrée (O1) d'horloge extérieure à l'autre état, a pour résultat de verrouiller les valeurs se trouvant dans les colonnes d'entrée (64) et d'achever le préchargement des colonnes de sortie (69) ainsi que le déchargement des rangées (68). On injecte ensuite une charge dans chacune des rangées (68), laquelle se propage dans les plans à la fois ET et OU, tandis que l'entrée (O1) de l'horloge extérieure demeure à l'état alterné. A la différence des circuits logiques MOS complémentaires dynamiques à deux plans classiques, l'on n'a pas besoin de circuit d'horloge entre les deux plans.

Abstract: Additions of conditioning agents to a particulate-containing flue gas stream are controlled by a controller operating from feedforward and feedback signals received from sensors in the combustion and gas cleanup system, and, optionally, from the power consumption level of the electrostatic precipitator. The flow rates of the conditioning agents, such as sulfur trioxide and ammonia, are thereby balanced to achieve an optimal removal of particulate matter and also sulfur and sulfur compounds from the gas stream before it is exhausted to the atmosphere. A typical feedforward signal is the boiler loading, and typical feedback signals include residual sulfur trioxide and ammonia levels and stack gas opacity.

Abstract: An apparatus (20) is provided for transferring articles (40-40) from a pickup position to a pickoff position and thence to a dropoff position. The apparatus includes a pair of pickup arms (60-60) which are spaced apart to engage lugs (42-42) oppositely extending from an article to be transferred. As the transfer arms are caused to be moved rotatably, the article is transferred to the pickoff position whereat the lugs are adjacent to stepped end portions (88-88) of a pair of pickoff arms (80-80). Further movement of the transfer arms causes the article to engage surfaces (92-92) of the stepped free ends of the pickoff arms and to be supported by engagement of the lugs with surfaces (94-94) of the stepped end portions of the pickoff arms. Afterwards, the pickoff arms are turned to allow the article to descend until, at a predetermined position, the lugs of the article become engaged with a conveyor ( 100) and become disengaged from the pickoff arms. Successive ones of the articles are supported by engagement of the lugs with the conveyor such that main body portions of the articles are submerged in a treating bath beneath the conveyor.
