Patent CA-2149005-A1 (CA)
Title: Ring network system
Inventor: TATTERSALL DAVID
IPC: H04L12/437
Filed: 1995-05-09
Abstract: A ring network system (1) has at least one node M which acts as a master or sender node to transmit an outgoing signal  (O.S.1)  having  a  relative  address  determined according to the relative location of the addressee node in the system.  As the outgoing signal passes through each node in turn, it is changed and a node recognises that it is the addressee node if the relative address has a pre-determined common addressee value.   The addressee node generates a return signal (R.S.1) with a node identifier which is transmitted in the opposite direction to the outgoing signal and the sender node ensures that this is received for a valid poll.   The master node  (M)  may automatically  configure   itself   by  retrieving  the identifier of all nodes in response to outgoing signals. This allows nodes to be easily added or deleted.   Each node on the return path adds data which it has captured together with its identifier so that data may be captured from all nodes between the sender node and the addressee nodes.    A  node  (M)  may  transmit  outgoing  signals alternately in opposite directions in a manner whereby the addressee nodes are selected so that each communication link  (3-8)  is omitted in sequence and fault diagnosis takes place.

Title: Zero discharge mill distillation, salt recovery, and water management
Inventor: NYKANEN TUOMO S
IPC: D21C11/10
Filed: 1993-12-07
Abstract: In minimizing effluents from a cellulose pulp mill, liquid effluents from a bleach plant are concentrated, and then incinerated to produce a residue including sodium, sulfate, and sodium chloride. This residue is distilled with sulfuric acid to produce gaseous hydrogen chloride and remaining residue, the HCI being used in chloride dioxide production for the bleach plant, while the remaining residue is passed to the recovery loop (e.g. recovery boiler). Sulfur containing gases from the non-condensible gas system may be combusted to produce gaseous sulfur dioxide, which is then converted to sulfuric acid, to distill the residue. Where a non-chlorine bleach plant is provided, the liquid effluents may be concentrated in evaporators and then passed directly to the recovery boiler. The liquid streams in the mill are managed by a cascade principle to reserve the cleanest water for only those processes where it is needed while minimizing its use where it is not necessary.
Patent CA-2157418-A1 (CA)
Title: Beamformer using coefficient restrained adaptive filters for detecting interference signals
Inventor: HOSHUYAMA OSAMU
IPC: H04R3/00
Filed: 1995-09-01
Abstract: In an adaptive array beamformer, a spatial beamforming filter is connected to a sensor array for respectively filtering and summing array signals to produce a first filter output containing a target signal that arrives in a specified direction. First adaptive filters provide transversal-filtering the first filter output to produce a second filter output not containing the target signal, using a first error signal by restraining their tap weight coefficients. The array signals are further coupled to subtractors. Each subtractor detects a difference between the second filter output of the corresponding first adaptive filter and the corresponding sensor signal to derive the first error signal. Second adaptive filters provide transversal-filtering the first error signals of the subtractors to produce third filter outputs, using a second error signal, by restraining their tap weight coefficients. The third filter outputs are summed and subtracted from the first filter output to produce an output of the beamformer, which is supplied as the second error signal to the second adaptive filters.

Title: Indigo dye process
Inventor: GURLEY SALLY
IPC: D06P5/00
Filed: 1994-05-05
Abstract: An improved nonpolluting method of dyeing fibers or fabric, including natural cellulose fibers such as cotton or linen, using indigo dye. The improved process includes pretreating the fibers with a mordant solution, preferably a natural nonpolluting mordant solution. The fibers are then treated with a reduced indigo liquor in an inert atmosphere, preferably nitrogen. The indigo is then oxidized by flooding the dyed fabric with cold water. This indigo dye process can be adapted to conventional garment, package and piece dye processes and machinery, which has not been possible with existing indigo dye processes. The improved process results in a more consistent and even dyed material which is color and washfast.

Abstract: A method and apparatus for training a text classifier is disclosed. A supervised learning system and an annotation system are operated cooperatively to produce a classification vector which can be used to classify documents with respect to a defined class. The annotation system automatically annotates documents with a degree of relevance annotation to produce machine annotated data. The degree of relevance annotation represents the degree to which the document belongs to the defined class. This machine annotated data is used as input to the supervised learning system. In addition to the machine annotated data, the supervised learning system can also receive manually annotated data and/or a user request. The machine annotated data, along with the manually annotated data and/or the user request, are used by the supervised learning system to produce a classification vector. In one embodiment, the supervised learning system comprises a relevance feedback mechanism. The relevance feedback mechanism is operated cooperatively with the annotation system for multiple iterations until a classification vector of acceptable accuracy is produced. The classification vector produced by the invention is the result of a combination of supervised and unsupervised learning.
