Inventor: FUCHS EBERHARD
IPC: C07D201/08
Filed: 1998-08-21
Abstract: The invention relates to a process for producing cyclic lactams by reacting aminocarboxylic acid nitriles with water, in liquid phase, in a fixed bed reactor, in the presence of a catalyst containing a catalytically active oxide comprising no soluble constituent under the reaction conditions. This process is characterised in that the catalyst is composed of shaped bodies which can be obtained by shaping the oxide into shaped bodies and by treating the oxide with an acid which is hardly soluble, having 0.1 to 30 % by weight of the oxide, before or after the shaping process.

Abstract: L'invention concerne un procédé permettant d'extraire rapidement des analogues, potentiellement actifs, de composés de plomb. Ce procédé consiste à générer et cribler à partir d'une importante base de données, des empreintes à plusieurs conformations tridimensionnelles de produits de combinaison physiquement possibles, essentiellement en liant des radicaux temporairement à un groupe compact. Ce procédé consiste ensuite à enregistrer des modèles tridimensionnels de radicaux dans une base de données fantôme de produits de combinaison, pour toute structure moléculaire accessible au sein de la base de données fantôme, à détecter tout atome présentant des caractéristiques de propriétés physiques du type pharmacophorique. Pour les paires de pharmacophores détectés dans chaque structure moléculaire, ce procédé consiste à calculer toutes les distances entre les atomes impliqués dans chaque conformation de cette molécule et à créer une densité de répartition de distance; à générer un vecteur d'empreinte de conformation qui contient toutes les densités de distribution de distances des paires de pharmacophores; à définir une fonction de calcul pour chaque empreinte moléculaire représentant l'importance relative des caractéristiques pharmacophoriques; à générer les empreintes pour le composé de plomb et comparer ces empreintes avec chaque empreinte de la bibliothèque potentielle selon la fonction de calcul susmentionnée, maximisée pour le plomb et extraire les molécules de la bibliothèque potentielle pour laquelle la fonction de calcul donne des valeurs inférieures à un seuil spécifié.

IPC: H04B7/26
Filed: 2000-06-02
Abstract: A method for operating a communication system includes steps of: (a) receiving a call for a user terminal at a satellite system gateway, the call originating from another user terminal; (b) examining a database to determine if the called user terminal is located within a coverage area of the satellite system gateway; and (c) if yes, formulating a paging message and transmitting the paging message to the called user terminal via at least one satellite. Upon the called user terminal responding to the page, the method further: (d) establishes the call using satellite system resources, (e) designates one of the calling or called user terminals as a call manager for the duration of the call, and (f) makes a temporary assignment of satellite system resources to the call manager user terminal for use in managing the remainder of the call. The step of establishing the call includes a step of assigning at least an initial channel/circuit pair to each of the user terminals. A call synopsis is transmitted from the call manager user terminal to the gateway at the completion of the call, and the gateway employs the call synopsis when transmitting billing-related information from the gateway to another gateway with which one or both of the user terminals has an affiliation. The other gateway could be a virtual gateway that serves a localized region within the service region of the gateway. At the completion of the call the assigned satellite system resources are relinquished. Also disclosed are methods and apparatus for extending the effective service regions of gateways and virtual gateways through a gateway-to-gateway diversity technique, wherein gateways are interconnected for providing user terminal traffic and signalling information between themselves at call setup and during a call.

Title: Hierarchical transmission digital demodulator
Inventor: KATOH HISAKAZU
IPC: H03D3/00
Filed: 1998-11-30
Abstract: A hierarchical transmission digital demodulator which can perform stable synchronism establishment and stable demodulation by setting its demodulating operations based on a reception C/N value. The reception C/N value is measured by a CNR  measuring circuit (10) upon receiving the demodulated output of an arithmetic circuit (1).  Carrier reproduction is performed based on a demodulated output obtained by demodulating the modulated wave in a header section and the modulated wave of a burst symbol signal during the period until synchronism establishment, and, after synchronous acquisition, performs the demodulation output in the header section based on the output of a logical gate circuit (11) and carrier reproduction based on the burst symbol signal and a QPSK signal when the C/N value is intermediate. When the C/N value is high or low, the demodulator switches a carrier reproducing loop to a higher gain by means of a gain control circuit (8) based on a signal from the logical gate circuit (11).
Patent CA-2313860-A1 (CA)
Inventor: SHARTLE ROBERT JUSTICE
IPC: G01N33/543
Filed: 2000-07-11
Abstract: A distinctive optical signature permits a fluidic medical diagnostic device to measure an analyte concentration or a property of whole blood, particularly the coagulation time, only after first insuring that a whole blood sample has been introduced into the device.      A suitable device has at one end a sample port for introducing a sample and at the other end a bladder for drawing the sample to a measurement area. By requiring a meter, used in conjunction with the device, to first detect the distinctive optical signature, a sample is drawn to the measurement area only if it is whole blood.      In that case, a channel carries the sample from the sample port to the measurement area, and a stop junction, between the measurement area and bladder, halts the sample flow. The meter measures a physical property of the blood sample - typically, optical transmittance - after it has interacted with a reagent in the measurement area.
