Title: Method and apparatus to speed up the path selection in a packet switching network
Inventor: ALFONSI JEAN-PIERRE
IPC: H04L12/56
Filed: 1994-05-12
Granted: 1999-02-16
Abstract: Currently, the routing algorithms compute all the available paths in the network, from the source node to the destination node before to select the optimal route. No assumption is made on the network topology and the route computation is often time and resource consuming. Some paths which are calculated are not acceptable due to the particular geographical configuration of the network. In the real world, large transport networks are not fully meshed. The present invention is based on the observation that networks are usually built around a hierarchical structure. A set of nodes, interconnected by high throughput lines, are used to build a 'Backbone' (401) with a high degree of meshing to allow the redundancy and reliability required by the user. The other nodes or 'local' nodes (404) are attached to one or several backbone nodes. It is the network designer responsibility, at the configuration time to define for each node what is its attribution: backbone (402) or local node (404). The list of the node attributions appears in the topology table (306) and is updated each time a node is added to or dropped from the network. The routing algorithm can take advantage of the particular network topology to drastically reduce the complexity of paths computation. For a given connection, only a limited number of nodes are eligible and are taken in account by the algorithm in the optimal route search. The object of the invention is to split the network in backbone and local nodes to speed up the path selection.

Abstract: Casing spacers for isolating carrier pipe mechanically, galvanically, and chemically from pipe casings. The spacers may be attached using fasteners to pipe joint restrainers or other ring structures which encircle carrier pipe. The spacers are more efficient to install in the field, provide robust mechanical structure and physical stability which does not degrade over time, provide additional protection to the pipe joints, and, because they may be attached to conventional structures instead of requiring an integral ring structure for encircling a pipe, alleviate the distribution and inventory problems encountered by conventional systems in which the casing spacer runners are attached to an integral ring structure which must conform to the carrier pipe size and the casing inner diameter.

Patent CA-2187208-C (CA)

Granted: 2004-06-29
Abstract: In prior art multi-phase electric machines in which conductor parts are interlace to form conductor lanes for various phases, the connection points are on the winding end, thus permitting only a very limited local possibility for welding of the conductor ends. In addition, the manufacturing cost is increased with an odd number of phases, since the design is asymmetrical and a number of different formers necessary is relatively high. The invention calls for prefabricated conductor parts (17) to be welded or soldered in the zones which will subsequently be located in the soft magnetic body. Divided bars with a high conductor cross-sectional area are connected before the insertion of soft magnetic segments, connection zones which are large relative to the conductor cross-sectional area are realized, and problems with the insulation are avoided. In three-phase machines, the conductor lanes are interlaced with each other, all conductor lanes being identical in design and the same pattern is repeated every four pole pitches. This connection technique and conductor progression permits the inexpensive manufacture of reliable electric motors and generators as well as uniform space utilization in three-phase equipment.

Abstract: In  the  process  and  installation  for decontaminating a liquid effluent contaminated by at least one organic substance, a gaseous combustible is burned in a reactor to produce a flame containing hydroxyl free radicals OH° and oxygen O2 and that flame is centered on the geometrical axis of the reactor. A helical flow of liquid effluent is produced on the inner cylindrical wall of the reactor to cause a direct contact between the hydroxyl free radicals and the  organic  substance  contaminating  the  liquid effluent.  By means of the hydroxyl free radicals, the organic substance is oxidized in liquid phase.  The high temperature of the flame enables completion of the oxidation of the organic substance,  in liquid phase, by means of the oxygen O2 present in the flame. At the outlet of the reactor, the liquid and gaseous products  are  separated;  the  liquid  product  is collected while the gaseous product is evacuated.
