Patent CA-2111544-A1 (CA)
Inventor: COX RICHARD V
IPC: H04L1/00
Filed: 1993-12-15
Abstract: A receiver for decoding N received branchword signals is disclosed. Illustratively, the branchword signals are generated by a tailbiting convolutional coder. The receiver stores received branchword signals in memory such that the branchword  signals are accessible in a logically circular sequence. The receiver then performs Viterbi updates on the logically circular sequence of branchwords, the sequence comprising more than N branchwords. Each Viterbi update provides a decision vector. The receiver stops performing Viterbi updates in response to anindication that Viterbi update decisions have become repetitive. A set of generated decision vectors resulting from the Viterbi updates is then modified in response to the indication. A decoded signal is generated by performing a Viterbi traceback procedure using the modified set of decision vectors. The indication that Viterbi update decisions have become repetitive may be provided by a predetermined fixednumber of Viterbi updates, the number reflecting an estimate of when said updatedecisions will likely become repetitive. The indication may also be provided by a comparison of decision vectors generated by Viterbi updates on the same stored branchword to determine whether the vectors are substantially equal. Or, the indication may be provided by a comparison of a pair of path metric vectors generated by Viterbi updates on the same stored branchword to determine whether differences between metric signals of one or more respective trellis state pairs of the path metric vectors are substantially equal. Modification of the set of generated decision vectors may include replacing a one or more decision vectors of the set with one or more later-determined decision vectors of the set. Alternatively, such modification may include extending the set of decision vectors by repeating previously determined decision vectors of the set.

Title: System for Cross-Connecting High Speed Digital Sonet Signals
Inventor: UPP DANIEL C
IPC: H04B10/27
Filed: 1989-12-08
Abstract: A modular, expandable, non-blocking system for cross-connecting high speed digital signals is provided.  The system is capable of connecting DSn, CEPTn, and STSn signals as desired, with lower rate signals being included as components of the high-rate signals or terminating on low speed lines, as desired.  The system accomplishes its goals by converting all incoming signals into a substantially SONET format, and by processing all the signals in that format.  The signals are typically cross-connected in the substantially SONET format, although an expandable non-blocking wide band cross-connect module provided which cross-connects any like signals.  If the outgoing signal is to be in other than SONET format, the substantially SONET formatted signal is reconverted into its outgoing format,  To create a complete system, various modules are utilized, including: add/drop multiplexer means for add/drop applications of DS-0, DS-1, CEPTn signals, etc.; a SONET bus interface; a virtual tributary cross-connect module which cross-connects virtual tributary payloads in space, time, and phase to generate new substantially SONET formatted signals; a wide band cross-connect module; a DS-3/SONET converter; and front end interfaces including a DS-3 line interface, and various STSn interfaces.  The modules may be mixed and matched as desired to accommodate a multitude of applications.

Title: Flotation Processes
Inventor: HOECKER WALTER
IPC: B03D1/002
Filed: 1994-02-23
Abstract: Disclosed is a process for the flotation of a mineral concentrate comprising thesteps of forming an aqueous slurry of a milled mineral ore containing particles of a desired mineral species and adding a flotation reagent which causes a desired variation in the flotation tendency of the desired mineral species present within the slurry so as to increase the efficiency of separation of that mineral species from the slurry relative to a situation where said flotation reagent is absent from the slurry. A stabilizing agent is introduced to the slurry in an amount which creates electrochemical conditions conducive to separation of the desired mineral from the slurry and causes the destruction of a deleterious component from the slurry which consumes the flotation reagent thereby maintaining or improving the efficiency of separation of the desired mineral species from the slurry of milled ore.

Inventor: FISHER DONALD E
IPC: A01G29/00
Filed: 1994-03-03
Abstract: An irrigator has an annular reservoir, open radially inwardly. A wall on the inside of the reservoir closes the open inner side and contains a bed of soil for growing plants. Wicks trickle moisture from the reservoir into the soil bed. In preferred versions of the irrigator, an impermeable plastic insert is designed to fit into the centre of a scrap vehicle tire as the reservoir. When inserted forcefully into one side of the tire, the tire is locked firmly onto the insert on one side to form a reservoir that has an opening between the opposite side of the tire and an upwardly tapered centre wall of the insert. When set into the ground, plants may be grown in the centre of the insert with moisture being fed into the centre growing zone from within the tire by wicks leading through appropriate slots in the insert wall.

Title: Composite type screen
Inventor: SATOMI HITOSHI
IPC: B01D29/01
Filed: 1994-03-09
Abstract: ABSTRACT OF THE DISCLOSURE         A composite type screen includes a machine main body divided into a first structural part in which a primary processing chamber is contained and a second structural part in which a secondary processing chamber is contained and a screen plate is interposed between the surfaces of the first structural part and the second structural part defined by the division.  Since a first rotary shaft having an impeller mounted thereto is disposed in the primary processing chamber and a second rotary shaft having a rotor mounted thereto is disposed in the secondary processing chamber, the first rotary shaft does not pass through the first screen member.  As a result, a seal member for the first screen member is not needed, whereby the number of parts is reduced and moreover a paper material can pass through the entire region of the first screen member and the area thereof through which the paper material passes is increased, so that a foreign substance removing efficiency can be improved.

Inventor: BILLINGS DOUGLAS W
IPC: G06F11/00
Filed: 1994-08-18
Abstract: A high availability method and system manipulate and store document images and coded data.  The method and system include an image local area network and a coded data local area network.  The image local area network is operated at a high utilization because of the relatively large size of the image files transmitted over it.   The coded data local area network is operated at a relatively low utilization level because of a relatively small size of the codeddata files transmitted over it.  Two or more work group servers are connected tothe image local area network.  Each work group server is connected through a work group local area network to the coded data local area network.  Each work group server operates in both a primary mode to service its own work group LAN and in a hot standby mode to serve as a backup processor for its corresponding work group server when the corresponding work group server is in a failure mode.  When the failure mode occurs, a local area network manager reroutes image files from the first work group local area network over the under utilized coded data localarea network, to the second work group local area network and its work group server which is operating in a hot standby mode.   In this manner, a high availability is provided for the image file processing and coded data processingby providing alternate LAN links having adequate capacity to accommodate the large rerouted image files.
