Title: Tissu industriel pourvu de carreaux asymetriquement perces
Inventor: BAKER SAM
IPC: B32B3/10
Filed: 2002-03-18
Abstract: Cette invention concerne un tissu industriel perméable formé à partir d'une pluralité de carreaux distincts assemblés en au moins deux couches, ces deux couches étant rattachées l'une à l'autre au moyen de structures d'attache conçues d'une seule pièce avec les carreaux. Dans ces tissus, pour chaque carreau, les structures d'attache sont incorporées au niveau de premiers emplacements choisis selon un motif symétrique, et les ouvertures des carreaux, qui assurent au tissu la perméabilité requise, sont incorporées au niveau de deuxièmes et troisièmes emplacements selon deux autres motifs, dont au moins un est asymétrique. Cette combinaison de motifs symétriques et asymétriques permet de réguler dans une certaine mesure la perméabilité du tissu ainsi formé.

Abstract: Robinet, appareil et système de distribution de bière, qui permettent de distribuer une boisson généralement sous pression telle que la bière dans un récipient de service avec des résultats convaincants. La boisson passe par un robinet de distribution de conception nouvelle, qui possède une buse dont l'orifice est conçu pour communiquer un mouvement circulaire ou tourbillonnant au flux de boisson sortant du robinet. Le flux de boisson est projeté dans le récipient, dans un mode de réalisation, de préférence directement vers la base du récipient où, sous l'effet de son mouvement, il tourbillonne dans le récipient à mesure qu'il le remplit. Cela produit un effet visuel agréable sur le client pendant le remplissage et permet une présentation convaincante de la bière aux consommateurs.

Abstract: An injector has a single tapered valve controlling fuel flow to a plurality of outlet passages.  The entrance to each outlet passage has an orifice surrounded by a raised valve seat.  Each valve seat is separated from the other valve seats by a recessed space.  The valve pivots as it is displaced from the valve seat to allow fuel flow through the outlet passages, and is constrained against other motion within the injector.

Title: Chloride controls in fossil fuel fired wet scrubbing process
Inventor: DOWNS WILLIAM
IPC: B01D53/50
Filed: 1990-11-21
Abstract: ABSTRACT OF THE DISCLOSURE        A process and an apparatus for the wet scrubbing of the flue gases from a fossil fuel fired plant comprise a dust collector for removing fly ash and dust from the flue  gases.   The  dust  free  gas  is  supplied  to  a prescrubber having a scrubbing liquor return for spraying scrubbing slurry into the flue gases to produce a slurry in  a  sump  of  the  prescrubber.    Some  of  the  slurry  is returned to an input of the prescrubber while some of the slurry is supplied over a bleed line to a flue gas line. The slurry is sprayed into the flue gases in the flue gas line. The  sprayed  slurry  is  dried  and  precipitated  as particles in the dust collector  to remove concentrations of chloride containing products from the process.  A main absorber  is  connected  to  the  prescrubber  for  further scrubbing of the gases and a thickener is connected to the main absorber for  thickening the slurry produced in  the main absorber.  The slurry is filtered to produce a filter cake.    Best   results   are   achieved by limiting   the temperature drop in the flue gas line which is due to the spraying  of  slurry  to  about  20°F  and  by  operating  the prescrubber  at  a  pH  of  4.0  to  4.5  for  avoiding  the absorption  of   SO2   in   the  prescrubber   while   still producing effective HC1 scrubbing.

Title: Method for recovering zinc from zinc-containing waste materials
Inventor: AUNE JAN A
IPC: C22B4/04
Filed: 1990-12-18
Abstract: ABSTRACT   The present invention relates to a method for recover zinc from zinc-containing materials, especially from zinc-containing material recovered from waste gases in metallurgical smelting processes. Particulate zinc-containing materials are agglomerated together with a carbonaceous reduction material and optionally slag forming materials, and are supplied to a gas tight closed electrothermic smelting furnace containing a molten bath kept at a temperature between 1200 and 1700°C in which the agglomerates are smelted and subjected to selective reduction and volatilization of zinc and other volatile metals. An inert slag phase and optionally a liquid metal phase are tapped from the smelting furnace, and zinc and other volatile metals are recovered from the waste gas from the smelting furnace by condensation. In order to prevent reoxidation of metallic zinc the particulate zinc-containing materials are agglomerated together with a carbonaceous binder which cracks at a temperature below 700°C and forms carbon black, and that the temperature in the gas atmosphere in the smelting furnace is kept above 1000°C in order to maintain a volume ratio between C02 and CO in the gas atmosphere in the smelting furnaces below 0.3.
