Inventor: GLANCE BERNARD
IPC: H04L69/40
Filed: 1998-01-05
Abstract: A mesh telecommunications network with improved reliability for transporting information, known as traffic, is presented. The network includes a plurality of nodes interconnected by a plurality of links. Nodes direct the flow of traffic into, out of, and through the network, and links provide the means of traffic transport between nodes. Each pair of connected nodes has a number of links therebetween. Most links provide dedicated traffic transport, while at least one link is a spare link that can be selectively used with other spare links to form alternative traffic paths for restoring traffic that has been disrupted by one or more inoperative working links. Spare links can be pre-connected to form selectable standby alternative traffic paths for substantially immediate alternative traffic transport. Preferably, control of the network is decentralized to enable nodes to more quickly form alternative traffic paths and to reduce the likelihood of network-wide failures.
Patent CA-2278379-A1 (CA)
Inventor: SCHMALZ STEVEN CHRISTOPHER
IPC: G01R31/12
Filed: 1999-07-22
Abstract: An arcing fault detector band pass filters the ac current in a protected circuit to generate a sensed current signal with pulses having an amplitude related to the step increases in current produced each time an arc is struck. The envelope of this pulse signal is tracked by a first, slow tracking circuit or envelope detector having a first, long time constant and a second, fast tracking circuit having a second, shorter time constant. When the second tracking signal generated by the second tracking circuit falls below a predetermined fraction of the first tracking signal of the first tracking circuit, a charge pulse modulator generates a pulse of a size which is a function of the amplitude of the most recent pulse in the sensed current signal. When a time attenuated accumulation of the charge pulses maintained on an integrating capacitor reaches a preselected level, an output circuit generates an arcing fault indication.

Filed: 1998-04-17
Abstract: A process for the preparation of a catalyst useful for conducting carbon monoxide hydrogenation reactions, especially a Fischer-Tropsch catalyst, use of the catalyst for conducting such reactions, especially Fischer-Tropsch reactions, and the composition produced by said process. In the preparation of the catalyst, a solution of a multi-functional carboxylic acid having from about 3 to 6 total carbon atoms, preferably about 4 to 5 total carbon atoms, is employed to impregnate and disperse a compound or salt of rhenium and a compound or salt of a catalytic metal, or metals, e.g., copper or an Iron Group metal such as iron, cobalt, or nickel onto a refractory inorganic oxide support, e.g., titania. The rhenium, which need be present only in small amount permits full and complete reduction of the catalytic metal, or metals, dispersed by the acid. Higher catalyst activities with lower rhenium loadings are thus achieved than in previous preparations where higher concentrations of rhenium were required to both effectively disperse, and reduce the catalytic metal, or metals, during the preparation. Surprisingly, as little as about 1/10 of the rhenium is required to accomplish the reduction promotion where the dispersion is effected with the acid.

Title: Multi-port ram based cross-connect system
Inventor: BECKER KENNETH A
IPC: H04Q11/04
Filed: 1999-10-29
Abstract: A high capacity digital non-blocking cross-connect switching fabric is realized by employing a multi-port RAM based space-time switch having a plurality of write circuits and a plurality of read circuits, each of which operates at a timing rate that is a prescribed fraction of the input/output clock rate of the input/output ports of the multi-port RAM based cross-connect switching fabric. The at least one multi-port RAM switch unit has a plurality of write circuits and a plurality of read circuits, each of which operates at a timing rate that is a prescribed fraction of the input/output clock rate of the input/output ports of the multi-port RAM based cross-connect switching fabric. Additionally, in one embodiment, each of the write circuits and each of the read circuits has independent and unrestricted access to all data storage positions in each of a plurality of storage units that make up the at least one multi-port RAM switch unit. Because the write circuits and each of the read circuits are operating at the prescribed fraction of the multi-port RAM switch unit input/output clock rate, a multi-port RAM based cross-connect switching fabric is realizable which has a significantly larger storage capacity that is accessible within a reasonable access time. In one embodiment of the invention, a plurality of multi-port RAM switch units is employed to realize a multi-port RAM based non-blocking cross-connect switching fabric. In a specific embodiment, the fractional write rate is exploited so that a plurality of input ports can be served by a single write circuit. In another embodiment, each write circuit is assigned exclusive access to a particular segment of the write address space that is different from that assigned to any other write circuit. Furthermore, since the read circuits are operating at a fraction of the output port clock rate, each of the read circuits can serve a plurality of output ports by delivering read signal elements from the multi-port RAM switch unit to the output ports in a round robin fashion.  Additionally, in another embodiment of the invention, each read circuit is assigned exclusive access to a particular segment of the read address space that is different from that assigned to any other read circuit. Consequently, the capacity of the multi-port RAM based cross-connect switching fabric is markedly increased.
