Title: Digital receiver
Inventor: GIELIS GERARDUS CHRISTIAAN MAR
IPC: H04N5/44
Filed: 1991-11-07
Abstract: Receiver comprising an A/D converter (5) for digitally sampling an analog signal modulated on a carrierfrequency at a first sampling frequency, consecutively coupled to a digital quadrature mixer stage (6) for a carrier frequency shift of the digitized modulated signal from the A/D converter, a digital filter device (10,11) for selecting the phase quadrature signals of the quadrature mixer stage and for decimating the sampling frequency from said first sampling frequency to a second sampling frequency, and a digital demodulation device (12,13). To obtain a receiver which can be easily realised in an integrated form and for which less crystal surface is required than for the digital integrable receivers hitherto known, and which is particularly suitable for receiving RF radio or TV broadcast signals, the digital quadrature mixer stage comprises a first coordinate rotation digital computer (Cordic) (9) in the rotation mode, having at least a first signal input which is coupled to an output of the A/D converter and a phase signal input to which a periodical digital sawtooth-shaped phase signal is applied from a digital sawtooth generator (SG) for a periodical 2π phase rotation of at least the signal applied to the computer  via  the first signal input at a repetition frequency which is equal to the magnitude of said carrierfrequency shift.

Abstract: Built-up deposits on the top surface of a tubesheet (13) and on adjacent tube sections in a tube bundle 11 of a tube bundle heat exchanger are removed by inducing vigorous turbulent flow of cleaning liquid radially across the surface of the tubesheet by repetitively and periodically injecting gas pulses into the liquid through one or more gas injection nozzles (30), preferably a single nozzle proximate the plate centre, to form an expanding and retracting gas bubble. The gas pulse rise time is smoothed by controlling the actuation time of a discharge valve and by a surge volume downstream of the valve to thereby avoid harmful pressure shock waves in the heat exchanger. The cleaning liquid is recirculated through an external filter loop (35,37) to remove suspended foreign materials dislodged by the turbulent flow.

Abstract: A nuclear reactor system pressure vessel comprises a steel inner liner part (22), an intermediate insulative layer part (47) and an outer prestressed concrete part (40) encasing these parts. Use of the pre-stressed construction allows for construction of pressure vessels of larger size than heretofore, and this coupled with utilization of squatter reactor cores (36) allows natural convective circulation in the reactor vessel of the heated water pool in the higher capacity systems currently being introduced. The reactor pressure vessel because of its suitability allows enhanced natural steam separation in the vessel and eliminates need for use of centrifugal steam separators. The outer vessel part can be a cast single piece structure or it can be an integrated concrete segment assembled structure embodying pre-stressing tendons arranged in various orientations to effect pre-stressing. Further, the major portion of the pressure vessel can be disposed below grade to lessen the presence of vessel structure in a nuclear system containment. Cooling passages are provided in the pressure vessel to carry off reactor decay heat as well as heat in the concrete outer vessel part.

Abstract: An information reproducing apparatus according to the present invention is capable of overcoming a problem of impossibility in data reproduction taken place due to a deletion of a SYNC signal or a RESYNC signal or generation of a false signal. If the above-described signal has been deleted, a normal RESYNC position estimation pulse estimated from the previous signal is used in place of the deleted signal. As for the false signal, the structure is arranged in such a manner that only one signal is generated by arranging the RESYNC window circuit (12) or the delay circuit and that the generated signal does not give bad influence to the detection of next RESYNC signal. Therefore, the above-described requirement is achieved by an addition of a simple structure.

Abstract: Opsonine ayant été isolée à partir de sérum humain et présente à des niveaux élevés dans du sérum normal par rapport à la protéine LBP de phase aiguë. L'opsonine comprend une protéine se présentant sous forme purifiée, laquelle est capable de se lier à des lipopolysaccharides afin de former un complexe reconnu par un récepteur sur des monocytes, des cellules macrophages et des cellules polymorphonucléaires et laquelle présente une masse moléculaire apparente d'environ 90 kD déterminée par analyse SDS-PAGE. Après caractérisation approfondie de l'opsonine, cette dernière apparaît comme étant un complexe d'une protéase et d'un substrat destiné à cette dernière. Le substrat semble présenter une similitude structurelle avec l'inhibiteur de protéine C, et l'on croit que l'opsonine est dérivée d'une cascade de protéases dont la disponibilité permet une interaction avec les lipopolysaccharides. L'invention présente des utilités dans les domaines du diagnostic et de la thérapeutique, ainsi que des techniques de tests, des matières sous forme de kit, des matières et des techniques de recombinaison, ainsi que des compositions pharmaceutiques.

Filed: 1991-02-04
Abstract: Procédé servant à acheminer une demande de service dans un réseau (100) comprenant des noeuds (101-104) interconnectés avec des liaisons. Le réseau est aussi conçu de façon que chaque noeud puisse communiquer avec chacun des autres noeuds. A des intervalles de temps présélectionnés, des ensembles d'itinéraires dans le réseau sont générés en réaction à la configuration du réseau et aux informations de trafic. De même, à des intervalles de temps prédéterminés, des facteurs d'occupation sont calculés en fonction de la configuration du réseau et en réaction aux informations de trafic. Les facteurs d'occupation sont proportionnels à des facteurs d'occupation non associés et aux facteurs d'attribution relatifs aux appels des diverses paires de noeuds; chacun de ces derniers facteurs est dérivé d'un plan d'acheminement nominal dans lequel un appel de la paire de noeuds correspondante n'est traité comme perdu que s'il est bloqué sur tous ses itinéraires autorisés. A intervalles prédéterminés, les données d'utilisation du trafic sont mesurées. A intervalles réguliers, les facteurs d'occupation correspondant à l'état occupé-inactif des liaisons sont utilisés pour calculer des valeurs d'occupation (340) relatives à chacun des itinéraires. Les valeurs d'occupation qui ne dépassent par un seuil prédéterminé génèrent des ensembles d'itinéraires séquentiels (350) pour chaque intervalle. Le trafic offert est alors acheminé séquentiellement par les ensembles d'itinéraires séquentiels.
