Abstract: The present invention is directed to the upgrading of heavy hydrocarbon feedstock that utilizes a short residence pyrolytic reactor operating under conditions that cracks and chemically upgrades the feedstock. The process of the present invention provides for the preparation of a partially upgraded feedstock exhibiting reduced viscosity and increased API gravity. This process selectively removes metals, salts, water and nitrogen from the feedstock, while at the same time maximizes the yield of the liquid product, and minimizes coke and gas production. Furthermore, this process reduces the viscosity of the feedstock in order to permit pipeline transport, if desired, of the upgraded feedstock with little or no addition of diluents. The method for upgrading a heavy hydrocarbon feedstock comprises introducing a particulate heat carrier into an upflow reactor, introducing the heavy hydrocarbon feedstock into the upflow reactor at a location above that of the particulate heat carrier so that a loading ratio of the particulate heat carrier to feedstock is from about 15:1 to about 200:1, allowing the heavy hydrocarbon feedstock to interact with the heat carrier with a residence time of less than about 1 second, to produce a product stream, separating the product stream from the particulate heat carrier, regenerating the particulate heat carrier, and collecting a gaseous and liquid product from the product stream.

Abstract: The present invention provides a routing protocol that scatters a stream of packets along a number of parallel paths, the packets being treated independently. The next hop for each packet is chosen probabilistically by comparing the resistance of available options. The resistance of a given hop depends upon the time the packet would spend in an output buffer from the current node, the time the packet would spend in the input buffer of the next hop node, the transfer time between the nodes 0 and the number of hops that the packet would take from the current node to the ultimate destination of the packet using the shortest path. This routing protocol is more efficient that shortest path first routing under simulation.

Abstract: The present invention relates to a method and an arrangement for shells (1a, 1b) fired from launch weaponry, using some of the barrel pressure built up in the barrel during the launch phase for an additional active function over and above that of giving the shell (1a, 1b) in question its trajectory velocity.  According to the invention, during the launch phase, some of the propellant powder gas accelerating the shell is therefore introduced into a chamber (12, 38, 60) which is arranged in the same and which is delimited in at least one direction by an element (8, 31, 58, 52, 53) which is movable relative to the rest of the shell and on which the barrel pressure acting on the shell simultaneously acts to maintain the original direction as long as the shell is located inside the barrel during the launch phase. This technique can thus be used to remove protective casings covering the fins, in order to push out fin units and to deploy initially retracted fins.
