Title: Method for producing propylene from methanol
Inventor: HACK MARKUS
IPC: C07C1/24
Filed: 2001-05-22
Granted: 2007-10-02
Abstract: According to the method, methanol vapour is reacted on a first catalyst to obtain a first vapour mixture containing dimethylether (DME) and a product mixture containing propylene is then produced from the first vapour mixture on a shape-selective zeolite catalyst. The shape-selective zeolite catalyst is provided as a feed material in at least two shaft reactors that are connected in series. A first sub-stream of the first vapour mixture containing DME is fed together with water vapour into the first shaft reactor. A first intermediate product mixture is drawn off from the first shaft reactor and fed to the second shaft reactor, whereby a second sub-stream of the first vapour mixture containing DME is also supplied to the second shaft reactor. A product mixture is drawn off from the last shaft reactor connected in series and a propylene fraction is separated, whereby residual substances that are in part gaseous are also obtained. At least one part of the residual substances is re-supplied to at least one of the shaft reactors.

Abstract: A method for combusting a wood log includes positioning the log within a combustion chamber with the log first end positioned above the log second end so that the log longitudinal axis is generally angled relative to and adjacent the chamber base wall and so that the log and the chamber base wall define a generally triangular air volume therebetween. The log is maintained in the angled configuration during at least part of the combustion process. A log supporting structure facilitates use of the method. The structure includes a supporting rod and a spacing base extending from the latter for resting on the base wall of a combustion chamber. The spacing base has a generally flaring configuration and allows gas to flow between the chamber base wall and the supporting rod in a first flow direction generally parallel to the supporting rod, and in a second flow direction generally perpendicular to and away from the rod from the log first end toward the log second end.

Abstract: The CA125 gene has been cloned and multiple repeat sequences including the carboxy terminus have been identified. The CA125 molecule comprises three major domains: an extracellular amino terminal domain (Domain 1); a large multiple repeat domain (Domain 2); and a carboxy terminal domain (Domain 3) which includes a transmembrane anchor with a short cytoplasmic domain. An amino terminal extension is present. The structure is dominated by a repeat domain comprising 156 amino acid repeat units, which encompass the epitope binding sites. More than 60 repeat units have been identified. The repeat units encompass the site of OC125 and M11 binding. Expression of the repeats was demonstrated. Any one of the repeat domains has the potential for use as a new gold standard for detecting and monitoring the presence of the CA125 antigen. The repeat domains and other domains also provide a basis for the development of a vaccine.

Title: Systeme pour le controle de systemes servant a verifier l'etancheite d'un corps creux

Granted: 2013-11-12
Abstract: L'invention concerne un système qui contrôle des systèmes servant à vérifier l'étanchéité d'un corps creux. Selon l'invention, on introduit dans le système au lieu du corps creux un corps de test (2) qui génère une augmentation de pression définie dans une chambre de mesure (4) pendant une durée prédéterminée. Cette augmentation de pression définie correspond exactement à l'augmentation de pression que génère un corps creux présentant une fuite faible, le corps creux étant alors reconnu comme tout juste étanche. Le corps de test peut être réalisé sous forme de capillaire de verre qui s'étend étanchéifié entre deux chambres à pression d'air différente. Selon un autre mode de réalisation, le corps de test peut être constitué d'un matériau qui peut absorber de manière définie au stockage de l'humidité provenant de l'atmosphère ambiante. Lorsqu'un vide est généré autour du corps de test, ce dernier restitue de l'humidité qui s'évapore au moins partiellement dans le vide, ce qui entraîne une augmentation de pression dans la chambre. Cette augmentation de pression correspond à l'augmentation de pression tout juste tolérée pour un corps creux à tester.

Granted: 2012-12-04
Abstract: A seat assembly is adapted to be mounted along a floor of a motor vehicle. The seat assembly includes a seat cushion frame having a forward end and a rearward end for supporting an occupant on the seat assembly. The seat assembly also includes a front support structure pivotally coupled to the forward end of the seat cushion frame. The front support structure pivots the seat assembly between a generally horizontal seating position and a generally upright tumbled position. In addition, the seat assembly includes a locking strut extending between a first end, which is coupled to the front support structure, and an opposite second end, which is coupled to the rearward end of the seat cushion frame. The locking strut locks and retains the seat assembly in any location between the seating position and the tumbled position in response to an acceleration force exerted on the seat assembly above a predetermined threshold. As a result, inadvertent pivoting of the seat assembly towards the seating position is prevented.
