Title: Method and apparatus for hierarchical bandwidth distribution in a packet network
Inventor: CLANCY ROBERT T
IPC: H04L12/56
Filed: 2002-01-08
Abstract: A scheduler apparatus provides bandwidth guarantees to individual data packet flows as well as to aggregations of those flows (referred to as "bundles") in a completely transparent manner, i.e., without using any additional scheduling structure. For each bundle, the scheduler determines the ratio between the bandwidth nominally allocated to the bundle and the sum of the individual bandwidth allocations of the flows that are currently backlogged in the bundle.  The scheduler uses that ratio to modulate the timestamp increments that regulate the distribution of bandwidth to the individual flows. In this manner, the greater the ratio for that bundle, the more the bandwidth that each backlogged flow in the bundle receives.

Title: Mixer
Inventor: HIROOKA YUICHI
IPC: B01F27/93
Filed: 1999-05-31
Abstract: The present invention provides a pin mixer which can surely prevent deposition of the solid mass of slurry on the pin or the toothed edge of the rotary disc, in spite of a simplified arrangement. The mixer comprises a housing into which a powdered material and a quantity of water is introduced, a rotary disc positioned within the housing. A peripheral edge of the disc is configured to be a circular profile concentric with a circumferential inside wall surface of an annular outer wall. Lower pins are provided with the rear bulged portions which extend rearward of the rotational direction R, and upper pins are provided with front bulged portions which extend frontward of the rotational direction R. The disc does not have a toothed formation on its peripheral edge zone so that the slurry can be prevented from depositing on the outer periphery of the disc. As the front and rear bulged portions are provided, retentive regions of the slurry are not formed in rear and front faces of the lower and upper pins, which may otherwise cause vortex or turbulent flow of the slurry, and therefore, deposition of the solid mass of slurry on t:he lower and upper pins can be prevented.

Abstract: La présente invention concerne des cellules mammaliennes conjuguées à un haptène, ainsi que leurs méthodes de préparation et d'utilisation. La conjugaison d'un haptène à des cellules mammaliennes permet d'empêcher efficacement la croissance des cellules, et elle peut être utilisée à la place de tout traitement classique, notamment l'irradiation. Ainsi, l'invention concerne des cellules mammaliennes en général, notamment, des cellules humaines, qui sont en phase de quasi non croissance, ainsi qu'une méthode permettant de maintenir ces cellules en phase de quasi non croissance par leur conjugaison à un haptène. L'invention concerne également des compositions renfermant des cellules tumorales et des extraits de tumeurs modifiés par un haptène, ainsi que des méthodes de traitement du cancer par administration d'une dose thérapeutiquement efficace d'une composition renfermant une cellule tumorale ou un extrait de cellule tumorale à un sujet nécessitant un tel traitement. Les cellules tumorales et les extraits de tumeurs selon l'invention, ainsi que les compositions les renfermant sont capables de produire des lymphocytes T susceptibles d'infiltrer une tumeur mammalienne, de déclencher une réponse immunitaire inflammatoire contre une tumeur de mammifère, de susciter une réaction d'hypersensibilité du type à retardement vis-à-vis d'une tumeur de mammifère et/ou stimuler des lymphocytes T in vitro. L'invention concerne, en outre, un échéancier de vaccinations efficace, permettant d'induire chez un patient mammifère atteint d'un cancer, une réaction antitumorale, et ce par induction d'un des phénomènes ci-après : nécrose tumorale, régression tumorale, inflammation tumorale, infiltration tumorale par des lymphocytes T activés, réaction d'hypersensibilité du type à retardement, et prolongation de la survie du patient. L'invention concerne enfin une méthode économique, simplifiée et améliorée de préparation de ces cellules tumorales conjuguées à un haptène en vue de leur administration sous forme de vaccin, laquelle méthode consiste à éliminer une étape séparée de traitement des cellules (par irradiation, par exemple) de manière à les maintenir en phase de non croissance.

Title: Enhanced direct digitising array arrangement
Inventor: MASSIE ANGUS
IPC: H03M1/12
Filed: 2000-11-02
Abstract: The invention comprises an array of ADCs, associated either with spatially separated signal input devices such as for example antennae, or with a single signal input device and a plurality of filters having a variable phase delay, which provide a digital output which is processed to remove spurious signals introduced by the ADCs thereby providing a linearised output. An array of N  antennae with respective band pass filters and ADCs (10) feeds received signals into a frequency channelisation device (12) which divides each of the N input streams into M lower bandwidth streams for distribution. In a first path, an FFT (14) is used to detect signals of interest, to determine where intermodulation products are likely to exist and to provide course data for the spatial processing used in the signal separation sub-systems. The second path (16) includes the detection and separation of co-channels signals. Signal classification techniques are then used to identify spurious signals, which are then removed.
