Title: High-temperature superconductor arrangement
Inventor: CHEN MAKAN
IPC: H01L39/16
Filed: 1998-10-22
Abstract: Layered ceramic high-temperature superconductors which are intended to be used as current limiters in alternating-current lines should have a bypass layer whose electrical resistivity is increased by more than 10 times with respect to that of the pure noble-metal bypass layer.      Preferably, a base-metal bypass layer of steel whose electrical resistivity is in the range between 10 µ.OMEGA.2 × cm and 100 µ.OMEGA. × cm at 77 K is soldered on or bonded to the superconductor layer. For electrical and thermal reasons, it is essential that the sheet resistance .rho.3/d3 of the base-metal bypass layer satisfies the following equation: (see formula I)

Patent CA-2256014-A1 (CA)
Title: Gigabit ethernet interface to synchronous optical network (sonet) ring
Inventor: BRULE JOHN
IPC: H04L12/56
Filed: 1998-12-14
Abstract: A method and apparatus for routing data packets via a synchronous optical (SONET) network from devices connected to a local area network to devices connected to other local area networks. At each transport node in the SONET network the data packets are unloaded from SONET payloads and requeued for transmission on an output path. This allows for easy resolution of contention between devices transmitting at the same time and avoids pre-assigning SONET channels. Source and destination address information from the data packets can be used to route the data packets through the SONET network. A time-to-live indicator can be used to find the shortest path to a destination address in a SONET ring network or any bi-directional ring network.

Patent CA-2265143-A1 (CA)
Inventor: KIM HELEN HAERAN
IPC: H03F1/02
Filed: 1999-03-10
Abstract: In a wireless transmitter, a class B or class C amplifier is used as a power amplifier for boosting the power level of a signal to be transmitted. To linearize the power amplifier, a feedback mechanism is included in the transmitter. The feedback mechanism provides for adjustment of a feedback gain which affects the overall gain of the signal, thereby effectively controlling the signal power level. In addition, a phase difference between components of the signal and the feedback versions thereof is corrected to increase the linearity of the power amplifier and stabilize the feedback mechanism.

Patent CA-2287102-A1 (CA)
Title: Salt grid for water softening system brine tank
Inventor: CHANNELL ALAN B
IPC: B01J49/00
Filed: 1999-10-19
Abstract: A salt grid for supporting salt above a portion of a concentrated brine solution in a bane tank for use in a water softening system. The grid comprises first and second platforms disposed at first and second elevational levels with respect to the vertical wall of the brine tank. The fluid level in the brine tank can be adjusted to be higher than the lower platform of the salt grid but lower than the upper platform of the salt grid. In this manner, salt dissolves only above the lower platform part of the grid and consequently, the din included in the salt only passes through the lower platform of the grid. The brine well which transports brine solution from the brine tank to the resin tank is located away from the localized area in which the dirt collects at the bottom of the brine tank. Leg extension members may be attached to the supporting legs of the salt grid to further raise the salt grid above the bottom of the brine tank, thereby increasing the volume of brine solution which forms below the salt grid.

Patent CA-2290289-A1 (CA)
Title: Cluster node distress signal
Inventor: BLOCK TIMOTHY ROY
IPC: G06F15/177
Filed: 1999-11-22
Abstract: The preferred embodiment of the present invention provides a cluster node distress system and method that improves the reliability of a cluster. The cluster node distress system provides a cluster node distress signal when a node within the cluster is about to fail. This allows the cluster to better to determine whether a non-communicating node has failed or has merely been partitioned from the cluster. The preferred cluster node distress system is embedded deeply into the operating system and provides a pre-built node distress signal that can be quickly sent to other nodes within the cluster when an imminent failure of any node is detected, improving the probability that the node distress signal will get out before the node totally fails. When the node distress signal is effectively sent to other nodes within the cluster, the cluster can accurately determine which node has failed and has not just been partitioned from the cluster. This allows the cluster to respond correctly, i.e., by assigning other nodes primary and backup responsibility, with less manual intervention and troubleshooting needed by administrators.
Patent CA-2293877-A1 (CA)
Inventor: BARTELS JAMES I
IPC: H01H47/00
Filed: 1999-12-30
Abstract: A power controller has upstream and downstream switches in series connection to provide redundant switching for power supplied from a power source to a load. A switch operating system closes the switch closer to the load first (downstream) and then the switch closer to the source (upstream). The operating system conditions closing the downstream switch on absence of power voltage on an upstream power terminal of the downstream switch. A preferred embodiment of the operating system performs a number of real time status checks during the connection process to assure that power voltage is properly absent and present at switch terminals during the stages of the connection process. This operating system guards against supplying power to the load if either the upstream or downstream switch's pair of contacts are welded at the time the connection process starts.
