Patent CA-2228701-A1 (CA)
Title: Production en phase aqueuse de peroxyde d'hydrogene et catalyseurs afferents
Inventor: FRIEDMAN GAD
IPC: C08F8/06
Filed: 1996-07-19
Abstract: Du péroxyde d'hydrogène est produit par un procédé dans lequel est utilisé comme catalyseur un polymère auquel sont fixés des groupes anthraquinone/anthrahydroquinone, présentant une solubililité différenciée dans l'eau. Le polymère est soluble dans l'eau dans un certain ensemble de conditions, par exemple dans une certaine plage de température, mais insoluble dans un autre ensemble de conditions. Ainsi, les groupes anthrahydroquinone liés au polymère sont oxydés en solution aqueuse et forment des groupes anthraquinone et du péroxyde d'hydrogène, lequel se dissout dans le milieu aqueux. Puis les conditions, par exemple la température, sont modifiées de façon à provoquer la précipitation du polymère, lequel peut alors être facilement séparé, en vue d'une réutilisation.

Filed: 1996-12-12
Abstract: The invention relates to a method and an arrangement for manufacturing a fibre product. The method and the process are characterised in that a first male mould (6) is immersed in stock in a moulding tank (2a). By means of a vacuum, fibres are induced to form a fibre layer of predetermined thickness on the male mould (6).

Title: Scheme for label switched path loop detection at node device
Inventor: OHBA YOSHIHIRO
IPC: H04L45/18
Filed: 1998-08-06
Abstract: A node device and a label switched path loop detection method which are capable of detecting a label switched path loop efficiently and quickly are disclosed. In a node device for carrying out the label switching, an ingress node information is included in a message that is to be successively transmitted from the upstream side in order to set up a label switched path, and the fact that the message with the same ingress node information for the same packet flow will be received from a previous hop node that is different from before if the label switched path has a loop formed thereon is utilized. Also, at a time of transmitting a message for the purpose of setting up a label switched path, if a node at which the label switched path for that packet flow already exists on the upstream or downstream side is encountered, this already existing label switched path is traced along the same or opposite direction as the flow, and the label switched path is set up if no loop is detected after tracing to the end.

Title: Bearing structure for roller shades
Inventor: CHOU TSER-WEN
IPC: F16C19/36
Filed: 1998-08-19
Abstract: An improved bearing mechanism works in conjunction with the control rod of a vertical blind system (21) or a roller shade (101, 301) system to provide superior bearing and load handling capability. A series of cylindrical roller bearings (31, 187, 271, 333, 351), are supported within the grooves, and against a central rotational member having a conical bearing (151, 359,391) for bearing against the rollers. a set screw (29) may be used to control the seating of the central rotational member within the conical bore (53), is used to make up any tolerance created through the manufacturing process, and can be used to increase the tension necessary to hold a roller shade in place. A balanced bearing system uses two sets of roller bearings (31, 187, 271, 333,351), which may be frusto-conical, to make for a more stable, more secure, and more evenly balanced roller shade assembly.

IPC: H04N19/593
Filed: 1997-05-02
Abstract: A television communications method and system particularly suitable for high definition, with narrow-band applications as for specialized broadcasting systems and video links using a block coding procedure to produce a system not wasteful of bandwidth caused by transmitting redundancies from multiple sources which do not contribute to picture quality. A differential order video encoding method (DOVE) provides a video coding scheme based on the need for true high-quality video with real-time TV encoding (14) and delivery in fifty percent of the bandwidth of the 4.5 MHz vestigial sideband suppressed television system in universal use.      Efficient coding algorithms, based on the finding and eliminating multiple source redundancies, characterizes the redundancies and creates, in real-time, an efficient set of codes for encoding (25) only the information that is different, eliminating the need for full 4.5 MHz bandwidth.

Patent CA-2253512-A1 (CA)
Inventor: SWINDLER DAVID L
IPC: H02H7/22
Filed: 1998-01-16
Abstract: An improved ground fault protection system is provided for protecting an electrical power distribution system having multiple sources and multiple grounds.      In accordance with a preferred embodiment, an electrical power distribution circuit having a primary electrical circuit for distributing electrical power from a plurality of sources to a plurality of loads is provided with a ground fault protection circuit magnetically coupled to the primary circuit. The primary electrical circuit includes conventional main and tie buses for distributing power to the loads and switches or circuit breakers for interrupting power from flowing in the buses. The ground fault protection circuit includes current sensors, tripping functions or ground fault relays associated with each circuit breaker and a novel use of an auxiliary transformer. When a ground fault occurs, the ground fault protection circuit is capable of sensing and determining the specific bus in which a ground fault condition exists. It then selectively sends a trip current generated by the associated current sensor only to the proper tripping functions for tripping the appropriate circuit breakers in the affected bus in order to isolate the ground fault; this avoids unnecessary tripping of circuit breakers in bus portions which are not affected by the ground fault. The auxiliary transformer uniquely sends the trip current to portions of the ground fault protection circuits that would not have been connected, or accessible, in the ground fault protection circuits of the prior art.

Title: Adaptation resource module and operating method therefor
Inventor: STACEY DAVID JOHN
IPC: H04L49/111
Filed: 1999-04-07
Abstract: In order to support both signalling processing on a per channel basis and multiple adaptation protocols, an interface (10) is modularised principally by function. Incident channels (60-62, Ch0-Ch n) are applied to a routing device (16) that consults a connection map (64) to determine an appropriate path, via an interface (90), for signal processing of each channel, as shown in FIG. 2. Modularised processing platforms (70-74) each contain a number of signal processors (80-86), with each processing platform providing an additional level of indirection with respect to channel handling. In this latter respect, one of the signal processors (86) on each platform is assigned to distribute channel processing to appropriately configured other ones of the signal processors and such that signal processing functions may be distributed between the other ones (80-84) of the signal processors. The present invention is particularly useful in relation to a narrowband-broadband interface to support differing adaptation protocols that require different signal processing functions and also to vary signal processing capabilities on a per call basis.
Patent CA-2269516-A1 (CA)
Inventor: SALVAIL PATRICK
IPC: B63H16/10
Filed: 1999-04-22
Abstract: The watercraft has an elongated hollow hull having a pair of integral outwardly and upwardly projecting outrigger wings, onto which are mounted oar mounting devices each having a flat casing attached to rods protruding out of the outrigger wings.  The attachment of the casing to the rods is accomplished by means of sockets installed on the rods, which have spherical housings engaged by ball joint portions provided on the casing, to form a ball and socket joint. The sockets are longitudinally spaced-apart on the hull side edge portion, so as to allow the casing to swivel about an axis parallel to the watercraft longitudinal axis. The casing is engaged by a pair of oar members pivoted therein in the plane of the flat casing. A pair of wires interconnect the pivoted oar members inside the casing, to allow pivotal displacement of the oar members only in opposite directions. The rods which protrude out of the outrigger wings are the ends of attachment rods crossing through the hull transversely, thus allowing a secure attachment of the oars onto the watercraft.
