Patent CA-2081036-A1 (CA)
Inventor: ABDELMONEM AHMED H
IPC: G06N3/02
Filed: 1992-10-21
Abstract: Errors or failures in a transmission system can be accurately predicted by a system which processes error or failure data collected by the transmission system during uniform intervals to yield data indicative of the errors or failures during each of a plurality of non-uniform, overlapping intervals. The errors or failures measured during the non-uniform intervals are selectively weighted and summed within a neural network, trained with historical error or failure data, to yield a set of predictions, each representing the predicted number of errors or failures during each non-uniform interval. The predictions from the neural network are then thresholded by a control unit and used to raise an alarm which signals the possibility of error or failure in the transmission system.

Inventor: SAKAI RYOICHI
IPC: G06F1/03
Filed: 1992-10-29
Abstract: A Direct Digital Synthesis type variable frequency signal generator generates a jitter free and stable output signal regardless of the address interval.  If the total number of addressable memory locations of a memory storing digital data is divisible without remainder by an initial address interval, then the memory is read every initial address interval with a clock signal of a predetermined frequency.  If the total number of addressable memory locations is not divisible without remainder by the initial address interval, then the address interval is modified to a value that is divisible without remainder into the total number of addressable memory locations and the clock frequency is modified in accordance with this modification of the address interval.  The memory is read every modified address interval with the modified clock signal.

Title: A method for removing impurities from an alkali metal chlorate process
Inventor: ERIKSSON STINA
IPC: C01B11/14
Filed: 1993-04-28
Abstract: The invention relates to a method for removing calcium ions and silicon compounds from various liquors produced or obtained in an alkali metal chlorate process, thereby reducing the operating cost and improving the possibility to close the process further. The calcium ions and silicon compounds are removed by addition of carbonate ions for precipitating calcium carbonate and by addition of an iron-containing compound for forming and precipitating a complex of iron ions and a silicon compound, whereupon the precipitates are co-separated from the liquor. The removal of calcium and silicate ions is substantially facilitated by the simultaneous separation of the precipitates.       Subsequently, the excess of carbonate ions can be reduced by acidifying the electrolyte for releasing carbon dioxide.

Title: Function Distribution in a Packet Switched Network
Inventor: DERBY JEFFREY H
IPC: H04L12/56
Filed: 1993-07-14
Abstract: A packet switched communication system employing ANR and/or multicast tree routing is improved by using a Copy ID field in the network header of the packet. The Copy ID field defines a control function and allows packet processing to be distributed among the several processors of each node. The selection of the processor (or processors) to receive the packet may be accomplished by making use of the routing field of the network header to qualify the control function specified in the Copy ID field. The control message is processed as defined for the control function by the processor receiving the packet. In multicast tree routing the control function is performed at all nodes in the multicast tree. In ANR routing, a prefacing "selective copy" bit is included in each label in the routing field of the network header; each node employed in the packet transmission path uses one label. The selective copy bit in each label triggers or not (according to its setting) the copy function in that node. The network control function specified in the Copy ID field may be performed in a given node when the copy function is triggered for that node. <IMAGE>
