Title: Plaque de transfert rotative double de canettes vers une courroie transporteuse
Inventor: WILLIAMS ROBERT
IPC: B65G47/86
Filed: 1997-02-28
Abstract: L'extrémité de sortie d'un décorateur de canettes cylindriques se déplaçant en continu à très grande vitesse est pourvue d'un appareil de déchargement ayant la forme d'une courroie à boucle fermée à déplacement continu (105) et d'un disque tournant en continu (102). Les canettes décorées sont amenées jusqu'au disque et leurs extrémités ouvertes orientées vers l'arrière s'engagent dans la face avant du disque en rotation et sont maintenues contre cette face avant, de préférence par des forces d'aspiration dirigées vers l'arrière. Les canettes sont déplacées par le disque à proximité immédiate d'une palette montante de la courroie, et sont transférées vers cette dernière par des forces d'aspiration dirigées vers l'avant et agissant à travers la palette montante de manière à attirer les extrémités fermées des canettes contre la palette montante. Les forces d'aspiration dirigées vers l'arrière agissent à travers le disque et sont appliquées au niveau des parties du disque qui occupent des positions angulaires sélectionnées pour faciliter le transfert des canettes vers le disque. L'application des forces d'aspiration dirigées vers l'arrière est interrompue au niveau des parties du disque occupant des positions angulaires où les canettes sont transférées du disque à la courroie. Lorsque les canettes décorées se composent de matériaux ferreux, les forces de transfert et de maintien par aspiration agissant sur les canettes peuvent être remplacées par des forces magnétiques.

Patent CA-2255215-A1 (CA)
Inventor: BRIDGES GREG
IPC: G06F19/00
Filed: 1998-12-07
Abstract: A method and system for modelling electromagnetic phenomena in three-dimensions is formed by three-dimensional interconnection of two-dimensional HPP cells, with operations at the junctions between cells to model the propagator properties of the phenomenon such as polarisation. The incorporation of polarisation as a property is performed in dependence upon the field component to which a cell contributes. During collision, like polarised propagators interact and during advection, associated field components to an original cell and a destination cell are determinative of a transform of propagator properties.

Title: A process for the isolation of protein concentrates on their native state from milk under sterile conditions
Inventor: MARTIN GENEVIEVE
IPC: A23J1/20
Filed: 1998-11-27
Abstract: The procedure includes the suspension of freshly collected milk in acetone or ethanol, then filtration under reduced pressure or centrifugation with or without an inert gas atmosphere. The process allows preservation of enzymatic activity of milk and presumably immunoglobulin properties, and native structure of lipids.    Acetone and ethanol have bactericidal and viricidal effects (Goodman et al. 1980) that provide the advantages of pasteurization while keeping the properties of raw milk. Traces of acetone and ethanol are removed by ventilation with air or an inert gas.

Patent CA-2263920-A1 (CA)
Title: Pre-biasing technique for a transistor based avalanche circuit
Inventor: DUNNE JEREMY G
IPC: G01S17/10
Filed: 1997-08-21
Abstract: A pre-biasing technique for a transistor based avalanche circuit which improves the initial rate of rise in the current applied through a laser diode or other light emitting device (122) in a laser based distance measurement and ranging instrument and, therefore, the sharpness of the leading edge of the laser pulse produced. Since the timing of the flight time of a laser pulse to a target and back to the ranging instrument is determined with reference to the leading edge of the emitted laser pulse, the inherent precision obtainable is enhanced by the production of a sharper leading edge pulse. The use of the pre-biasing technique disclosed also allows for the substitution of a much cheaper light emitting diode (122) in lieu of a conventional laser diode in an alternative implementation of a light pulsed-based distance measuring and ranging instrument.

Title: Error detection scheme for arq systems
Inventor: KHAYRALLAH ALI S
IPC: H04L1/18
Filed: 1997-09-22
Abstract: An error detection and correction scheme for automatic repeat request (ARQ) systems in which multiple copies of a received data packet comprising a CRC  field are compared to each other to determine the non-unanimous bit positions.  If the number of bit positions thus determined lies under a threshold, tentative packets with all possible configurations at the non-unanimous bit positions are tested on validity by CRC check. In order to account for the changes in the header fields between the multiple copies of a received data packet, the CRC fields are calculated before and after modifying the variable header fields of at least some of multiple copies of said received data packet.

Title: Reformulation et emballage combines retardant le rassissement des produits de boulangerie
Inventor: SMITH JAMES P
IPC: A21D8/04
Filed: 1997-10-24
Abstract: Les pertes dues au rassissement sont un des problèmes majeurs de l'industrie de la boulangerie. Ce problème peut être résolu par un procédé qui retarde le rassissement des produits de boulangerie associant en synergie la reformulation et un emballage sous atmosphère modifiée. La pâte est reformulée à l'aide d'un agent anti-rassissement, tel qu'une enzyme, une gomme ou un sirop de blé à haute teneur en fructose. La pâte reformulée est ensuite cuite et emballée sous une atmosphère gazeuse, par exemple de CO2, ou d'un mélange de N2 et de CO2, ou en présence d'un agent absorbant l'oxygène. Ce procédé permet de retarder le rassissement jusqu'à 42 jours.

Patent CA-2270053-A1 (CA)
Title: Dense wdm optical multiplexer and demultiplexer
Inventor: ALEXANDER STEPHEN B
IPC: G02B6/34
Filed: 1998-09-10
Abstract: In accordance with the present invention, optical channels to be demultiplexed are supplied to first and second optical fibers via an optical splitter. Low loss interference filters, for example , coupled to the first and second optical fibers, select respective groups of channels. Each group of channels is next demultiplexed with sub-demultiplexers into individual channels, each of which is then sensed with a corresponding photodetector. Although the optical splitter introduces an optical power loss at the input to the demultiplexer, the interference filters and sub-demultiplexers create little additional loss. As a result, the total power loss associated with the present invention is significantly less than that obtained with a conventional n channel demultiplexer based on a 1 x n splitter. Accordingly, large numbers of channel, e.g., in excess of forty, can be readily demultiplexed and detected.
Patent CA-2270863-A1 (CA)
Title: Method for assigning tasks, data processing system, client data processing nodes and machine-readable storage medium
Inventor: STAIGER WOLFGANG
IPC: G06F15/177
Filed: 1999-05-04
Abstract: The subject of the invention is a method for assigning tasks for processing received from one or several client data processing nodes (C1 through C5) within a group of at least two server data processing nodes (S1 through S4) to one of the server data processing nodes (S2), as well as a server data processing system, a client data processing node and a machine-readable storage medium for carrying out this process. A client data processing node (C2) that has a task to assign, first selects the server data processing node from the group that is the next server data processing node to be selected based on a predefined cyclical order. If the server data processing node that is selected first denies the processing of the task, the client data processing node randomly selects a different server data processing node for processing the task. Otherwise, the client data processing node assigns the task to the selected server data processing node.
