Abstract: A bandwidth transfer switching system (100) connecting various customer devices (12a-g), including local area networks (44), from customer premises (42) through a local loop (50) to a telco central office (50), to deliver switched circuit traffic to central office switches (60) and data packet traffic to wide area networks (64), such as the Internet. Access concentrators (104, 140) are employed at the customer premises (42), remote concentrators (106, 140) and optional relay nodes (160, 140) are employed in the local loop (50), and transfer switches (108, 140) are employed in the central office (56). Copper wire lines (166) and fiber optic lines (168) are used to handle typical protocols such as POTS, E1/T1/xDSL, and SONET between the various transfer nodes (140).

Abstract: Cette invention se rapporte à un bogie électrique (10) qui comprend une poutre de collecteur de troisième rail non suspendue (14) pour une suspension primaire à bras oscillant. La poutre de collecteur (14) et le collecteur de courant (12) associé à elle sont montés sur le châssis (20) du bogie, par l'intermédiaire d'adaptateurs de montage (22), de liens (30) et de bagues élastomères (28). Plus spécifiquement, la poutre de collecteur (14), à proximité des boîtes d'essieu (18) du bras oscillant, est fixée aux adaptateurs de montage (22) qui, à leur tour, sont suspendus sous les boîtes d'essieu correspondantes (18) par des liens (30) et des bagues élastomères associées (28). La déflexion par torsion des bagues élastomères (28) permet aux liens (30) d'osciller dans le sens longitudinal, autorisant ainsi des mouvements des boîtes d'essieu angulaires et longitudinaux relativement plus amples, créés par la suspension primaire à bras oscillant.
Patent CA-2360702-A1 (CA)
Inventor: BOGGS DAVID LEE
IPC: B60L50/16
Filed: 2001-10-31
Abstract: This invention relates to a hybrid electric vehicle component coolant control system and method. The coolant system has an electric pump to move coolant through a closed system including engine and motor components. Such components to be cooled can include any electric motors, power electronics, engine, and transmission. The preferred embodiment controls coolant flow to the vehicle engine and motor in a single closed loop.  Vehicle components have temperature sensors that send temperature signals to an electric coolant pump duty cycle control strategy. The control strategy makes a determination of a duty cycle of the electric coolant pump as a function of the temperatures of vehicle components and orders the duty cycle of the electric pump.  In the preferred configuration, engine temperature sensors can acquire either engine coolant temperature or engine cylinder head temperature. The preferred configuration includes a heater core in the coolant flow path connected between vehicle components and the electric coolant pump return, whereby passenger heating requests are facilitated.  Several coolant flow paths among the vehicle components are possible including a parallel and series configuration. The control system can also use a rolling average filter routine connected between the temperature sensor for the motor and the control strategy to determine the average temperature of the motor.

Title: Improved shock absorber
Inventor: BELL STEPHEN H
IPC: F16F9/46
Filed: 2000-01-31
Abstract: The present invention provides an improved method and apparatus for controlling and making real-time adjustments to damping in a shock absorber (100) based on driving conditions and desired driving characteristics. The shock absorber has a reservoir compartment (122) and a fluid-filled internal chamber (120) divided into a compression compartment (130) and a rebound compartment (128) by a movable piston (126). A piston rod (138) is connected to the piston (126) and extends through a seal (174) in the rebound end of the internal chamber (120). The shock absorber contains flow passages (410) connecting, and normally allowing fluid to flow between, the reservoir compartment (122), the compression compartment (130) and the rebound compartment (128). Fluid flow in the flow passages (410), which is directly related to the relative motion between the shock main body and the piston rod assembly, is controlled by providing a variable valve closing force (112). Control of the valve closing force, and thus the damping of the shock absorber, may be controlled in real-time either by the vehicle operator or an autonomous damping control system.

Inventor: LACHANCE RAYNALD G
IPC: C25B9/00
Filed: 2000-05-03
Abstract: It is an object of the present invention to provide an improved cell assembl y which reduces or eliminates fluid leakage. The invention provides an electrolyser, particularly, of the MSE or SSE type, wherein the circulation frames (38, 40) extend beyond the edges of the metallic current carriers (11 0) such that a circulation frame and/or gasket of a first cell is formed of an elastomeric material compatible with the elastomeric material of a circulati on frame and/or gasket of an adjacent second cell, which first and second cells  comprise a cell stack or cell block; and wherein the circulation frames exte nd beyond the edges of the metallic current carriers whereby the circulation frames may be bonded directly to adjacent non-metallic separators (36). Thus , the first and second cells may be joined directly together without current carrier metallic/non-metallic frame intervening boundary edges. This eliminates the need to provide gaskets at this boundary. This invention enables an entire cell block to be suitably encapsulated with elastomeric material to render the edges of the block to be hermetic and leak tight for both O2 and H2 gases and electrolyte.

Abstract: A fill cup is provided for a fluid filter having a housing and an end plate which enclose a filter element. The end plate has an inlet port for receiving unfiltered fluid and an outlet port from which flows filtered fluid. The fill cup includes a base having openings formed therein, a cylindrical rim which surrounds the base, and a hollow tube which extends axially through the base and rim. The tube forms a stub which projects away from the base and which is adapted to be coupled to the outlet  port of the filter. The tube also forms a hollow standpipe which is aligned with the  stub and which projects away from the base and into an interior of the cup. When the filler cup is mounted on the filter, the cup openings communicate fluid to the inle t ports of the filter, and the hollow tube prevents unfiltered fluid from directly entering into the outlet port and communicates air from the filter to atmosphere as the filter  is filled with fluid. The stub has external threads for screwing into the outlet port of the filter, and the base of the cup sealingly engages a seal mounted on the filter end plate.

IPC: H04B7/185
Filed: 2000-11-13
Abstract: In a satellite network with on-board switching and bandwidth on demand, traffic monitoring is required to facilitate billing data collection and to avoid congestion at the satellite. In addition to traffic monitoring, performance monitoring is necessary to quickly respond to link degradation or possible equipment anomalies.  Monitoring terminals (MTS) specially equipped with traffic measuring and policing and link performance measuring capabilities are used to monitor traffic and performance. The monitoring terminal (MTS) is located in each satellite beam to perform the monitoring functions for that beam. The monitoring terminals (MTS) are low-cost terminals that receive down-link traffic in their respective beam, and record statistics on a per transmit-terminal or per virtual connection basis. Records are periodically transmitted to a central location where they are processed for billing, enforcing traffic contracts, and taking actions against link degradations.

Filed: 2001-05-17
Abstract: In cross section, dryer screen has flat machine warp threads, and substantially round strongly shrinking cross direction weft threads. The threads form a single-layer wire cloth, and are shifted closer to one another due to cross directional shrinkage of the wire during heat treatment. Each warp thread in the wire cloth passes above two weft threads on the paper side of the cloth, below one weft thread on the machine side of the cloth. The adjacent warp threads show a shift of one weft thread in the machine direction. Each warp thread passes one weft thread in relation to the previous warp thread from a different point to the paper side and correspondingly to the machine side. After weaving, the paper side surface has empty spaces at the points where the warp threads pass below the weft thread. Each warp thread overlaps the adjacent warp threads at the empty spaces.
