Title: Adaptive dual-polarization communication of orthogonal frequency division multiplexed signals
Inventor: ABU-DAYYA ADNAN
IPC: H04L1/02
Filed: 2001-06-13
Granted: 2011-12-13
Abstract: A system and method is provided for adaptive orthogonal frequency division multiplexed (OFDM) transmission (ADOT). The system and method includes OFDM  processing of information symbols and is configured for transmission and reception of OFDM signals on orthogonally polarized antennas. Further, the system and method of the present invention is adaptable to channel conditions.  An ADOT transmit system includes a transmit processor configured for a specific OFDM modulation of incoming data symbols to be transmitted based on channel condition data, and a pair or orthogonally polarized transmission antennas. An ADOT receive system includes a receive processor configured for restoring the transmitted OFDM signals according to a transmission mode employed in the transmit system. Continual measurement of the transmission channel yields channel condition data for use in selecting a particular transmission mode.

Abstract: The preform of the biaxially drawn, blow-molded bottle comprises polyethylene terephthalate layers 2 and at least a gas barrier layer 3 laminated with the polyethylene terephthalate layers. The gas barrier layer 3 extends downward from a level halfway to the height of the neck 4 including the neck ring 5, or at least from above the neck ring 5, down virtually to the lower end of body 6. The gas barrier layer 3 inside the wall of the neck 4 has an average thickness corresponding to a third (1/3) or less of the maximum thickness of the gas barrier layer 3 inside the wall of the body 6, allowing most of the gas barrier material to be located in the wall of the body 6. Thus, the gas barrier material is effectively utilized, and in the case of the heat-resistant bottle, the neck has the predetermined dimensions without fail after the whitening treatment.

Abstract: The invention concerns an arrangement with two concentric shaftlines (15, 16) one of which overlaps the other, wherein a gasket-bearing sleeve (38) interposed therebetween is conical and supported on a spacer (40) of the outer shaftline, so that a nut (19) for mounting the front end is accessible from the rear passing through the gap (43) between the two shaftlines (15, 16), thereby enabling the nut to be unscrewed and the outer shaftline to be dismounted. The invention is applicable to front bearings of high pressure shaftlines of gas turbines and enables the high pressure body to be dismounted from the rear, without having to further detach components such as a fan at the front of the machine. The arrangement does not prevent a meshed gear (20) from being mounted.

Abstract: A dispensing closure, including a horizontal deck, an aperture through the deck, arid a collar depending below the aperture in the deck, is snapped over an annular bead on the neck of a molded plastic bottle. A stop wall, comprising a pair of ribs mounted for pivotal movement, is formed in the interior of the body of the closure; a gap is centrally located between the ribs. A radially projecting lug, which is triangular when viewed in side elevation, is formed on the sloping collar of the container; a dovetailed segment is defined at the free end of the lug. The collar on the closure has interrupted beads, so that the dispensing closure is secured to the container by snapping the interrupted beads over the annular bead on the neck of the container. The ribs of the stop wall flex pivotally outwardly when contacting the outer end of the lug. The dispensing closure is rotated relative to the container, in either the clockwise or counterclockwise direction, so that the dovetailed segment of the lug projects into the central aperture in the stop wall; the free ends of the ribs engage the dovetailed segment and lock the closure into proper alignment with the container.

Abstract: L'invention concerne une attribution de débit binaire de liaison de retour (RL) dans un système de débit binaire élevé (par exemple 1xEV-DO) en tant que fonction de la qualité du canal de liaison montante (FL). La formation de débit d'un profil de débit de terminaux d'accès multiples (AT) est réalisée par réglage des probabilités de transition associées à un algorithme d'attribution de débit binaire. Le débit binaire maximum de la RL par AT est réglé de manière à réduire la charge dans une zone désignée et à obtenir une formation de débit de la cellule et/ou du secteur. Dans un mode de réalisation, les débits binaires maximums sont réglés en tant que fonction du rapport signal/interférence et bruit (SINR) de la FL, tel que mesuré par secteur de service ou en tant que total de la somme saisie de SINR de FL. Dans un autre mode de réalisation encore, les débits binaires maximums sont réglés comme fonction des différences au niveau des valeurs montantes/thermiques entre des secteurs voisins.

Abstract: L'invention concerne un format d'analyse par immunochromatographie sur membrane permettant l'exécution d'analyses enzymatiques rapides. Une combinaison de constituants nécessaires pour susciter une réaction enzymatique spécifique, lesquels constituants sont soit absents de l'échantillon cible soit présents dans ce dernier en quantité insuffisante pour permettre l'exécution de la réaction désirée, est prédéposée sur un substrat à l'état sec avec des ingrédients nécessaires pour produire une couleur désirée dès l'apparition de la réaction désirée. La bande est pourvue d'un tampon à échantillon placé en amont du dépôt de substrat dans le flux d'écoulement, tampon sur lequel l'échantillon liquide est appliqué. Cet échantillon s'écoule du tampon à échantillon dans la zone du substrat, où ledit échantillon reconstitue immédiatement les ingrédients secs tout en se mélangeant étroitement à eux et en réagissant avec eux au niveau du front fluidique. Ce front fluidique se déplace rapidement dans la <= zone de lecture >= finale, où la couleur développée est lue par rapport à des normes de couleur prédéterminées pour la réaction désirée. Des tampons de prétraitement pour l'échantillon, si nécessaires, (p. ex. un tampon de lyse pour lyser des globules rouges de sang entier) sont placés devant le tampon à échantillon dans la voie d'écoulement de façon appropriée. Cette analyse dans le format de l'invention est plus rapide et plus simple à exécuter que des analyses chimiques par voie humide analogues. Ladite invention concerne également des analyses spécifiques pour la glucose-6-phosphate déshydrogénase (<= G-6PD >=), le cholestérol sérique total, l'activité .beta.-lactamase et l'activité peroxydase.

Title: A process for removing sulfur particles from an aqueous catalyst solution and for removing hydrogen sulfide and recovering sulfur from a gas stream
Inventor: KHATTATY MOHAMMAD REZA
IPC: B01D53/86
Filed: 2006-05-23
Granted: 2011-06-14
Abstract: The invention relates to a process for removing sulfur particles from an aqueous catalyst solution used to remove hydrogen sulfide from a gas stream (1, 5), comprising the steps of: directing a flow of a suspension (12) comprising reduced catalyst solution and sulfur particles to an oxidizer zone (20), where the catalyst solution is regenerated by contacting said suspension with a gas (22) containing oxygen; and removing sulfur from said suspension at least by gravity sedimentation at a bottom (21) of said oxidizer zone (20). According to the invention a flow deflecting means (34) is disposed at least at an outlet (35) for the oxidized catalyst solution leaving said oxidizer zone (20) such as to prevent any tur- bulent state caused at least by a stream of oxidized catalyst solution leaving said oxidizer zone (20) such as to reduce foaming and plugging of the whole system. A gas (27) is additionally injected at the conical bottom (21) of the oxidizer zone (20) in parallel to said slanted surface (23) for avoiding sedimentation and agglomeration of sulfur particles on said bottom (21). Heavy hydrocarbons are eliminated to further reduce foam production. Further, foaming and plugging is controlled by using proper packings in the absorber. Proper controls are used to avoid flooding. The temperature is adjusted such that not only the reaction rate in the oxidizer is high, but also the catalyst degradation is kept low. Thus excessive foaming and flooding of the oxidizer zone is avoided.
